in the list. If multiple media disks are required for an installation, then you might have to disconnect and
reconnect for every server when the new media disk is inserted in the DVD.
When a USB key is detected in the Active Onboard Administrator USB port and ISO images are present, they
appear on the DVD menu. Select the server blades you want to deploy an ISO image to, and then select the
ISO image from the menu. The ISO image deploys.
VLAN Configuration
Onboard Administrator 3.00 and higher provide a user-configurable IEEE 802.1Q tagged VLAN. This
feature enables you to completely isolate traffic from the server or the interconnect module by creating a
VLAN on the enclosure management network.
VLAN places no requirements or restrictions on the IP address. However, the external router or switch, which
the Onboard Administrator is connected to, must be configured as a VLAN trunk access mode to route and
pass multiple tagged traffic through the Onboard Administrators external Ethernet interface.
VLAN Features
• The VLAN ID is a unique number, which identifies each VLAN. The allowable range of VLAN ID
numbers is 1 to 4094. By default, VLAN is disabled, and all devices are set to VLAN ID 1. After a VLAN
is configured, devices that do not have the same VLAN ID cannot communicate with each other.
• All untagged frames received by Onboard Administrator are assigned to the default VLAN ID.
Onboard Administrator will respond with untagged frames. All tagged frames will have a VLAN ID or
tag in the frame and Onboard Administrator will respond with tagged frames.
• If a tagged frame is sent using the default VLAN ID, it will be dropped by Onboard Administrator, since
Onboard Administrator expects default VLAN ID frames to be untagged. If the destination is the server
or interconnect, then the Onboard Administrator responds with untagged frames.
• Since Onboard Administrator must communicate with all devices in the enclosure, all private
management network communication inside the enclosure needs to be a member of all the configured
VLANs on the system.
• Traffic between the iLO/IOM and the Broadcom switch is untagged, making VLAN transparent to them.
Incoming traffic destined to the device will be tagged by Onboard Administrator going into the
Broadcom switch which then removes the tag before sending the traffic to the device. The Broadcom
switch will add the default VLAN ID to the port the device is attached to the outgoing traffic of the device
before sending it out.
• The VLAN ID of the server, interconnect module, and Onboard Administrator is configurable to allow
Onboard Administrator to be part of any network by configuring the VLAN ID to match the default
VLAN setting of the external switch that the Onboard Administrator is connected to.
• The Onboard Administrator firmware will assign the default VLAN ID to all non-configured bays. The
default VLAN ID can be changed by the user. You can associate a name, limited to 31 alphanumeric
characters, to a VLAN ID. You can save up to 25 VLAN entries with a VLAN ID and name at one time.
• VLAN supports SAS interconnect peer-to-peer communication. There is also full interface support for CLI
and GUI along with limited support for LCD. You can enable and disable VLAN and view or change
VLAN IDs though the Insight Display. There is no VLAN support on the enclosure link and service port.
• Both active and standby Onboard Administrator are set to the same VLAN configuration settings,
causing any changes to the active Onboard Administrator to be made to the standby Onboard
Administrator as well. No changes can be made to the standby Onboard Administrator, but you can
view the settings.
