v Do not overtighten the cable straps or bend the cables to a radius of less than 38
mm (1.5 in.).
v Do not put excess weight on the cable at the connection point. Be sure that the
cable is well supported.
Installing SFP modules
The FAStT600 Storage Server host ports require Small Form-Factor Pluggable
(SFP) Modules. SFP modules are used to convert electrical signals to optical
signals that are required for fibre-channel transmission to and from RAID
controllers. The FAStT600 Storage Server supports two types of SFP modules; one
with a plastic latch and one with a wire latch. After you install the SFP modules, you
will use fiber-optic cables to connect the FAStT600 Storage Server to other
fibre-channel devices.
Before you install SFP modules and fiber-optic cables, read the following
information:
v The SFP module housing has an integral guide key designed to prevent you from
inserting the SFP module improperly.
v Use minimal pressure when you insert the SFP module into a port. Forcing the
SFP module into a port could cause damage to the SFP module or the port.
v You can insert or remove the SFP module while the port is powered on.
v The operational loop performance is not affected when you install or remove an
SFP module.
v You must insert the SFP module into a port before you connect the fiber-optic
cable.
v You must remove the fiber-optic cable from the SFP module before you remove
the SFP module from the port. See “Removing SFP modules” on page 28 for
more information.
To install an SFP module, complete the following steps.
Statement 3:
CAUTION:
When laser products (such as CD-ROMs, DVD drives, fiber-optic devices, or
transmitters) are installed, note the following:
v Do not remove the covers. Removing the covers of the laser product could
result in exposure to hazardous laser radiation. There are no serviceable
parts inside the device.
v Use of controls or adjustments or performance of procedures other than
those specified herein might result in hazardous radiation exposure.
