Chapter 1: Overview
AT-SBx31CFC Fabric Control Card
The AT-SBx31CFC Fabric Control Card provides two functions: the
central switching fabric between all the Ethernet line cards and the central
controller for management and control of the chassis.
Note
One AT-SBx31CFC supports up to 200 Gbps of bidirectional
Ethernet traffic. When two AT-SBx31CFC Fabric Control Cards are
installed, the switching load of the network traffic is shared between
the switching fabric circuitry on each of the line cards resulting in a
potential system throughput of 400 Gbps.
The Switchblade x3112 Management Software resides on the
AT-SBx31CFC Fabric Control Card which monitors and configures the line
cards via the controller circuitry. Either one or two AT-SBx31CFC Fabric
Control Cards may be installed yielding a non-redundant or redundant
controller configuration respectively.

eco-friendly
Button
The eco-friendly button on the AT-SBx31CFC Fabric Control Card front
panel controls the activation of the status LEDs on all the chassis line
cards and AT-SBx31CFC Fabric Control Card and to initiate a lamp test
on all status LEDs. It is displayed in Figure 7.
You may elect to turn off the LEDs when you are not using them to monitor
the status on the line card ports or the overall system status. When the
LEDs are turned off via the eco-friendly switch, all of the LEDs in the
chassis are affected except for the M/S LED on the AT-SBx31CFC Fabric
Control Card(s) which is always illuminated. Also, the overall power
consumption of the chassis is slightly reduced – approximately 3 watts in a
system with 240 active copper ports.
Each time the eco-friendly button is pushed, a lamp test is initiated on all
LEDs in the chassis. The lamp test consists of LEDs flashing in alternating
colors for 3 seconds.
RESET
Figure 7 eco-friendly Button and Reset Button
RESET Button
You can use the RESET button to reset the controller and switch fabric
circuitry on the AT-SBx31CFC Fabric Control Card.This button is
displayed in Figure 7. Push the button only in the unlikely event that the
Switchblade x3112 Management Software is not responsive to CLI
commands or status requests. Depending on your configuration, you may
initiate a short interruption in the flow of network traffic through the switch
when you press the button.
If you press the RESET button with only one AT-SBx31CFC Fabric
Control Card installed, which is the active controller, all of the Ethernet line
cards are reset by the AT-SBx31CFC Fabric Control Card as part of its
boot up process.
Caution
When the RESET button is pressed with only one AT-SBx31CFC
Fabric Control Card installed, the Ethernet network traffic flow
through the switch is interrupted for up to two minutes while the
AT-SBx31CFC and Ethernet line cards reboot.
24

SwitchBlade x3112 Installation Guide
If you press the RESET button with two AT-SBx31CFC Fabric Control
Cards installed, the role of the active controller is “swapped” with the
inactive controller. This means that the inactive controller becomes the
active controller and the active controller becomes the inactive or standby
controller. During this process, the switch management function is
swapped to the new active controller. In this case, the inactive
AT-SBx31CFC becomes active immediately, and consequently, the
Ethernet line cards are not affected or reset.
Caution
With two AT-SBx31CFC Fabric Control Cards installed, the
switching fabric circuitry on each line card is shared. When you
press the RESET button, the Ethernet network traffic flow through
the switch is limited to 200 Gbps for up to two minutes. This is the
time required for the inactive AT-SBx31CFC Fabric Control Card to
reboot and for its switching fabric circuitry to become available again
for switching network traffic.
Note
The RESET switch is specifically provided for resetting the
AT-SBx31CFC Fabric Control Card. If you want to swap the
controller function between the active and standby AT-SBx31CFC
Fabric Control Cards, Allied Telesis recommends that you use the
SWAP commands provided in the Switchblade x3112 Management
Software. Refer the to the Software Reference for SwitchBlade
x3100 Series Switches on the ATI web site for specific information.
Network
Management
Port
The Network Management (NET MGMT) port is an RJ-45, 10/100/1000
Ethernet port. See Figure 8. This port provides an Ethernet interface for
remote management of the SwitchBlade x3112 Switch. Because this port
is intended to be connected to the network, you can connect an Ethernet
cable between the Network Management port and one of the Ethernet line
cards in the chassis. This provides a connection to a remote management
device or PC on the network via the AT-SBx3112 line cards.

Chapter 1: Overview
The NET MGMT port is a standard RJ-45 8-pin connector and can operate
at 10, 100, or 1000 Mbps in either half- or full-duplex mode. The cable
requirements for this port can be found in the table “Cable Requirements
for the 10/100/1000Base-T Management Port” on page 112. For the port
pinouts, refer to “Connectors and Port Pinouts” on page 110.
The default setting for the Management port is Auto-Negotiation with Auto
MDI/MDI-X. At the default setting, the port, which is IEEE 802.3u
compliant, sets its speed and duplex mode automatically with
Auto-Negotiation. You can disable Auto-Negotiation and set the speed
and duplex mode manually.
The wiring configuration of the port is set automatically with
Auto MDI/MDI-X to MDI or MDI-X, depending on the wiring configuration
of the end node. This allows you to use a straight-through twisted-pair
cable regardless of the wiring configuration of the port on the network
device. The Auto MDI/MDI-X feature is only available when the port is
using Auto-Negotiation. If the Auto-Negotiation feature is disabled with the
Switchblade x3112 Management Software, the port defaults to the MDI-X
setting.

Chapter 1: Overview
Note
The AT-SBx31GP24 and AT-SBx31GT24 line cards can only be
installed in slots 0 through 3 or 6 through 11 in the AT-SBx3112
Chassis.
Note
In the Switchblade x3112 Management Software, the CLI mnemonic
for these line cards are as follows:
AT-SBx31GT24 Line Card - “GE24RJ”
AT-SBx31GP24 PoE Line Card - “GE24POE”.
Connector Type
Speed
The ports are 8-pin RJ-45 connectors that use four pins at 10 or 100 Mbps
and all eight pins at 1000 Mbps. For the pin assignments, refer to
“Connectors and Port Pinouts” on page 110.
A port’s speed can be 10, 100, or 1000 Mbps. The speed can be set
automatically through Auto-Negotiation, the default setting, or manually
with the Switchblade x3112 Management Software.
Note
To operate at 1000 Mbps, a twisted-pair port is set to Auto -
Negotiation. You cannot set the speed of a twisted-pair port to
1000 Mbps manually.
Duplex Mode
A twisted-pair port can operate in either half- or full-duplex mode. (Fullduplex
mode is the only mode available when a port is operating at 1000
Mbps.) The twisted-pair ports are IEEE 802.3u-compliant and Auto-
Negotiate the duplex mode setting.
You can disable Auto-Negotiation on one or all of the switch ports so that
you can set the duplex mode manually through the Switchblade x3112
Management Software.
Note
If a switch port connected to a 10 or 100 Mbps end node that is not
using Auto-Negotiation, you should not use Auto-Negotiation to set
the speed and duplex mode, because a duplex mode mismatch
might occur. You should disable Auto-Negotiation and set the port’s
speed and duplex mode manually with the Switchblade x3112
Management Software.
Maximum
Distance
The ports have a maximum operating distance of 100 meters (328 feet).
30

SwitchBlade x3112 Installation Guide
Cable Type
The cabling requirements for a 10/100/1000Base-T port are:
For 10 Mbps operation: Standard TIA/EIA 568-B-compliant Category 3
or better shielded or unshielded cabling with 100 ohm impedance and
a frequency of 16 MHz.
For 100 Mbps operation: Standard TIA/EIA 568-A-compliant Category
5 or TIA/EIA 568-B-compliant Enhanced Category 5 (Cat 5e) shielded
or unshielded cabling with 100 ohm impedance and a frequency of 100
MHz.
For 1000 Mbps operation: Standard TIA/EIA 568-A-compliant
Category 5 or TIA/EIA 568-B-compliant Enhanced Category 5 (Cat 5e)
shielded or unshielded cabling with 100 ohm impedance and a
frequency of 100 MHz.
Auto MDI/
MDI-X
The twisted-pair ports on the switch are IEEE 802.3ab compliant and
feature Auto MDI/MDI-X. This feature, available when a port’s speed and
duplex mode are set through Auto-Negotiation, automatically configures a
switch port to MDI or MDI-X depending on the wiring configuration of the
port on the end node. This allows you to connect any network device to a
port on the switch using a straight-through twisted-pair cable.
If Auto-Negotiation is disabled on a port and the speed and duplex mode
are set manually, the Auto MDI/MDI-X feature is also disabled and the
port’s wiring configuration defaults to the MDI-X setting.
Port Pinouts
Refer to Table 17 on page 110 for the port pinouts when a twisted-pair port
operates at 10 or 100 Mbps in the MDI configuration and Table 18 on
page 110 for the MDI-X configuration. For port pinouts when a twisted-pair

Chapter 1: Overview
AT-SBx31GP24
Power over
Ethernet
The twisted-pair ports on the AT-SBx31GP24 PoE Line Card feature
Power over Ethernet (PoE). PoE is a mechanism for supplying power to
network devices over the same twisted-pair cables used to carry network
traffic. This feature can simplify network installation and maintenance by
allowing you to use the switch as a central power source for other network
devices.
A device that receives its power over an Ethernet cable is called a
powered device (PD). Examples of such devices are wireless access
points, IP telephones, web cams, and even other Ethernet switches. A PD
connected to a port on the switch receives both network traffic and power
over the same twisted-pair cable.
The AT-SBx31GP24 automatically determines whether a device
connected to a port is a PD or not. A PD has a signature resistor or
signature capacitor that the switch can detect over the Ethernet cabling. If
the resistor or capacitor is present, the switch assumes that the device is a
PD.
A port connected to a network node that is not a PD (that is, a device that
receives its power from another power source) functions as a regular
Ethernet port, without PoE. The PoE feature remains enabled on the port
but no power is delivered to the device.
Power Budgeting
The AT-SBx31GP24 PoE Line Card is capable of providing a maximum of
30W of power per port on all 24 ports for a total power consumption of 720
W, while at the same time furnishing standard 10/100/1000 Mbps Ethernet
functionality. See Table 10 on page 35 for the matrix of Class versus
power level output and the maximum number of ports.
Note
The maximum number of PoE ports in the SwitchBlade x3112
Switch is 240 ports.

The PoE power is supplied to the PoE ports on a first come basis. By
default, the highest PoE priority starts from slot 0, port 0 and decreases as
the PoE slot/port numbers ascend to the last PoE port.
For example, if you have one AT-SBx3165 PoE Power Supply and two
AT-SBx31GP24 PoE Line Cards are installed and 40 Class 4 PDs
connected to slot/ports 0/0 through 0/23 and 1/0 through 1/15, they all
receive the full 30 W of PoE power or a total of 1200W. If more than
40 PDs are connected, the highest slot/port numbers have a flashing
amber or fault condition because all the available PoE power (1200 W) are
allocated to the first 40 ports and no additional PoE power is available for
the additional PDs.
Note
The PoE port priorities can be reassigned using the port
configuration commands in the Switchblade x3112 Management
Software. Refer the to the Software Reference for SwitchBlade
x3100 Series Switches on the ATI web site for specific information.

Chapter 1: Overview
Implementation
A standard Ethernet twisted-pair cable contains four pairs of strands for a
total of eight strands. Network traffic at speeds of 10/100 Mbps requires
only four strands (1, 2, 3, and 6), leaving four strands in the cable unused
(4, 5, 7, and 8).
Note
1000BASE-T cables carry the network traffic on all eight strands of
the Ethernet cable.
The PoE standard, IEEE 802.3at, describes two alternative ways for
delivering power to a PD over twisted-pair cabling for 10/100 Mbps ports.
Alternative A uses the same strands that carry the network traffic
where Alternative B uses the spare strands of the cable. The PoE
implementation on the AT-SBx31GP24 PoE Line Card is Alternative A,
where power is transmitted over strands 1, 2, 3, and 6.
PDs that comply with the IEEE 802.3at standard typically support both
power delivery methods. A PD that is compliant with the standard receives
its power from the switch while using either a straight or crossover cable.
The AT-SBx31GP24 PoE Line Card works with most legacy PDs as long
as the device can be powered on pins 1, 2, 3, and 6. A legacy device is a
node that was manufactured before the IEEE 802.3at standard was
completed and, consequently, may not adhere to the standard. If this is
the case, a straight (MDI) cable may be needed to insure that the DC
polarity is correct.

AT-SBx31FAN Tray
The AT-SBx31FAN Tray consists of four fans with speed control and
status circuitry. It is a field replaceable assembly that is factory installed
and shipped with the AT-SBx3112 Chassis.
The fan tray is initialized by the Switchblade x3112 Management Software
which runs on the AT-SBx31CFC Fabric Control Card. The fan speed is
controlled automatically and is adjusted proportional to the internal
operating temperature of the switch. When the ambient temperature
coming into the fan tray is approximately 20 C, the speed of the fans are
their lowest. The fan speed increases to provide additional cooling as the
ambient temperature rises, which allows the line cards to operate properly
within the chassis.
You can find the Fan Status LED in the System Status LEDs on the
AT-SBx31CFC Fabric Control Card. See Figure 5, “System Status LEDs”
on page 22 for the location of this LED.

plug provided with the AT-SBx3161 System Power Supply and the AT-
SBx3165 PoE Power Supply assemblies has a 20 Amp, 125 V NEMA
5-20P plug. This plug is only compatible with a NEMA 5-20R
receptacle. See Figure 26, “100 - 125 VAC 125 V NEMA 5-20 Plug and
Receptacle”.
G
W
1965
Figure 26. 100 - 125 VAC 125 V NEMA 5-20 Plug and Receptacle
Ensure that the rack is safely secured and that it will not tip over.
Devices in a rack should be installed starting at the bottom, with the
heavier devices near the bottom of the rack.
The power outlet for the switch should be located near the unit and
should be easily accessible.
If the chassis has a system and PoE power supplies installed, the
power sources for multiple supplies of the same type should be on
different A/C circuits to protect the unit from a power circuit failure.
Use dedicated power circuits or power conditioners to supply reliable
electrical power to the network devices.
The site should provide easy access to the ports on the front of the
chassis so that you can easily connect and disconnect the network
cables, as well as view the unit’s LEDs.
Air flow around the unit and through the side and rear vents should be
unrestricted.
Do not place objects on top of the switch.
Do not expose the switch to moisture or water.
Ensure that the site is a dust-free environment.

54

SwitchBlade x3112 Installation Guide
Preparing the
Equipment Rack
To prepare for the installation of the SwitchBlade x3112 Switch into your
equipment rack, perform the following procedure:
Caution
Due to its weight, the chassis should be mounted as low as possible
in the equipment rack to maximize vertical stability.
1. Reserve 311.1 mm (12.25“) of vertical rack space for the installation of
the AT-SBx3112 Chassis as shown in Figure 27.
In addition, do not mount any other equipment within 152.4 mm (6”)
above this space during installation. This additional vertical space is
temporary and allows you enough room to lift and tilt the chassis into
its position in the equipment rack without hitting other equipment - see
Figure 31 on page 60. When the chassis is installed, this additional
space is available for any other equipment that you may install.
463.5 mm (18.25”)
311.1 mm (12.25“)
152.4 mm (6”0)

Chapter 2: Installation
2. Identify the lowest 1/2” screw hole pattern on the rack mounting rails
within the space reserved for the AT-SBx3112 Chassis. Install one
rack mount screw in each vertical rail - at the same height in the top
screw hole of the lowest 1/2” hole pattern as displayed in Figure 28.
The screws are used to support the chassis while you secure it to the
rack.

SBx31FAN Tray and shipping brace)
– Ten line card blank panels
– Three power supply blank panels
56

SwitchBlade x3112 Installation Guide
Adjusting the
Brackets
Before installing the AT-SBx3112 Chassis, you need to determine where
the horizontal position of the chassis front panel will be relative to the
vertical rack rails. The AT-SBx3112 Chassis rack mounting brackets come
installed from the factory so that the chassis is flush with the rack rails after
installation. See position “A” in Figure 29 on page 58.
You may decide to extend (positions “B” through “E” in Figure 29 on page
58) or recess (position “F” in Figure 30 on page 59) the horizontal position
of the chassis relative to the rack mounting rails. You can do this by
removing both rack mounting rails and re-attaching them in the
appropriate holes on each side of the chassis. The dimension (X) between
the front panel and the rack rails is given in Table 16 for each rack
mounting bracket position.

Protection Against Electrostatic Discharge (ESD)
Proper ESD protection is required when handling the SwitchBlade x3112
line cards and power supplies. You need properly grounded using wrist or
foot straps to eliminate the risk of ESD damage to the equipment.
Caution
Electrostatic Discharge (ESD) can damage components on the
SwitchBlade x3112 line cards and power supplies. Insure that
proper ESD procedures are followed during installation.
1. Verify that the chassis is electrically connected to earth ground.
2. Wear an ESD-preventive device such as a foot strap or wrist strap,
ensuring that it makes good contact with the user’s skin.
If a foot strap is used, the floor must be ESD conductive.
3. Connect the clip from the ESD-preventative device to the ESD socket
on the lower right side of the AT-SBx3112 Chassis front panel or an
unpainted surface of the frame or rack as displayed in Figure 38. This
ensures that unwanted ESD voltages safely flow to ground.

protective cover in the optical bores. When you do remove this cover,
keep it for future use.
Unnecessary removal or insertion of a transceiver can lead to
premature failure.
Warning
A transceiver can be damaged by static electricity. Be sure to
observe all standard electrostatic discharge (ESD) precautions,
such as wearing an antistatic wrist strap, to avoid damaging the
device.
To install an SFP transceiver in the your switch, perform the following
procedure:
1. Remove the transceiver from its shipping container and store the
packaging material in a safe location.

can be damaged by electro-static discharges (ESD). Follow the
procedure given in “Protection Against Electrostatic Discharge
(ESD)” on page 64 to guard against ESD damage when unpacking
and installing this line card.
Caution
Each of the line cards require that air actively flows across the
electronic circuits for proper operation. Ensure that the fan tray is
installed before powering any line cards.

SwitchBlade x3112 Installation Guide
Cabling the Twisted-Pair or Fiber Optic Ports
Observe the following guidelines when connecting a twisted-pair or fiber
optic cable to a port on the switch:
The connector on the cable should fit snugly into the port on the
switch. The tab on the connector should lock the connector into place.
Because the twisted-pair ports on the switch are auto-MDI/MDI-X, any
type of network device can be connected to a port on the switch using
a straight-through twisted-pair cable. If you disable Auto-Negotiation
on the port, the port defaults to MDI-X. For instructions on how to
configure a port, refer to the Software Reference for SwitchBlade
x3100 Series Switches on the ATI web site for specific information.
If your network topology contains a loop where two or more network
devices can communicate with each other over more than one network
path, do not connect the network cables forming the loop until after you
have activated a spanning tree protocol on the switch. Data loops can
adversely affect network performance.
If you are creating a port trunk, you must configure the Switchblade
x3112 Management Software before connecting the cables of the trunk
to the switch. Otherwise, a network loop will result which can adversely
affect network performance.
In order for a switch port to successfully Auto-Negotiate its duplex
mode with an end node, the end node should also be using Auto-
Negotiation. Otherwise, a duplex mode mismatch can occur. A switch
port using Auto-Negotiation defaults to half-duplex if it detects that the
end node is not using Auto-Negotiation. This can result in a mismatch
if the end node is operating at a fixed duplex mode of full-duplex.
To avoid this problem, disable Auto-Negotiation on a switch port and
set the port’s speed and duplex mode manually if the end node has a
fixed duplex mode of full-duplex.
87

Chapter 2: Installation
Installing the Chassis Blank Panels
Ten blank panels are supplied with the AT-SBx3112 Chassis. These
panels must be installed in vacant slots to insure proper airflow throughout
the chassis.
To install the blank panels, perform the following procedure:
1. Install a blank panel in each vacant slot from slots 0 to 11 where a line
card or a AT-SBx31CFC Card has not been installed.
2. Align the two thumb screws on the blank panel with the mounting
holes on the front panel rails of the chassis.
3. Finger tighten the two thumbscrews to attach the blank panel to the
chassis.
4. With a # 2 Phillips head screw driver, torque both thumbscrews to
.56 Nm (5 lb-in) maximum.
5. Repeat steps 2 through 4 for the remaining vacant slots.
6. Store any unused blank panels in a secure place for future use.

Chapter 3: Troubleshooting
AT-SBx31CFC Fabric Control Card SBx Status LEDs Flashing Amber
If a SBx Status LED is flashing amber, the line card has experienced a
FAULT or an error condition. See “SBx STATUS LED Description on the
Active AT-SBx31CFC Fabric Control Card” on page 23 for an explanation
of all status conditions.
Note
All line cards are hot swappable. This allows the AC power to be
connected to the SwitchBlade x3112 while you re-seat or exchange
line cards.
If a FAULT condition is encountered for one of the card slots, you can
attempt to restart the line card. The following example is for restarting
a card in slot 2:
officer SEC>> restart card 2
You will be prompted as follows - enter y for YES:
Do you really want to restart card 2 (Y/N)? y
Command has been submitted
officer SEC>>
If the RESTART CARD command is not successful, remove the line
card from the slot and re-seat until the face plate is flush with the
chassis front panel. Wait for 2 to 3 minutes for it to come on line. If it
successfully comes up, the SBx Status LED for the slot in question
turns to solid green.
You can obtain specific card status information for each card slot
through the Switchblade x3112 Management Software by entering the
SHOW CARD command as follows:
officer SEC>> show card
If the SBx Status LED for the slot continues to flash amber after the

SwitchBlade x3112 Installation Guide
AT-SBx31GP24 PoE Line Card Link LED is Off
Under normal operating conditions for a port with an active LINK status,
the LINK LED for each port is either solid GREEN or AMBER, or it is
flashing GREEN or AMBER. Refer to “AT-SBx31GP24 Port LEDs” on
page 32 for the LINK LED location and Table 9 on page 33 for the LINK
LED description. If a Link LED is off, do the following:
Verify that the end node connected to the port is powered ON and is
operating properly.
Check that the twisted-pair cable is securely connected to the port on
the switch and to the port on the end node.
Make sure that the twisted-pair cable does not exceed 100 m
(328 ft).
Verify that you are using the appropriate category of twisted-pair cable:
Category 3 or better for 10 Mbps operation, Category 5/5E for 100
Mbps 1000 Mbps and Category 6/6E for 10GBASE-T operations.
Determine if a crossover cable is required. Since the twisted-pair ports
feature auto MDI/MDI-X, you should be able to use a straight-through
cable regardless of the type of device you connect to a port. However,
if you disable auto-negotiation on a port and set a port’s speed and
duplex mode manually, the port defaults to MDI-X.
Verify that the twisted-pair cable is not faulty by replacing it with a
known good cable
Make sure that the operating parameters of the port on the switch are
compatible with the end node to which the port is connected. This may
require that you use the Switchblade x3112 Management Software.

Chapter 3: Troubleshooting
Power not Received on PoE Device
If you attached a powered device (PD) to a port on a AT-SBx31GP24
card, the PoE LED for the port should be green. If the device is not
receiving power or the PoE LED is flashing amber, steady amber, or is
OFF, do the following:
Check to be sure that the PD is designed to receive power over pins 1,
2, 3, and 6 on the RJ-45 port. This can be verified by reviewing the
device’s documentation or data sheet.
Check that the device’s power requirements do not exceed 30 W. This
can be verified by reviewing the device’s documentation or data sheet.
Verify that the PD is not faulty
Verify that you are using the appropriate category of twisted-pair cable:
Category 3 or better for 10 Mbps operation, Category 5/5E for 100
Mbps 1000 Mbps and Category 6/6E for 10GBASE-T operations.
Verify that the twisted-pair cable is not faulty by replacing it with a
known good cable.
Use the Switchblade x3112 Management Software to determine
whether PoE is enabled on the port. The default setting for PoE is
enabled.
Use the Switchblade x3112 Management Software to determine
whether the PoE power setting for the port has been reduced from the
default setting of 30 W, to a value below the power requirements of the
device.
Verify that the power budget on the switch is not being exceeded by
the number of PDs and their load requirements. This should not be a
problem for the AT-SBx31GP24 card, which can support PDs on all
ports 1 to 24, assuming the connected devices require no more than
30 W/port. However, if the total number of ports in the AT-SBx3112
chasssis exceeds the maximum allowed with the number of AT-
SBx3165 PoE supplies, this will result in a FAULT condition for those
ports over the limit. Refer to “IEEE802.3at Classes versus AT-
SBx31GP24 Power Levels” on page 35 for the maximum number of
ports supported for each Class.
