The FAStT900 Storage Server uses fiber-optic cables to connect to other Fibre
Channel devices. The fiber-optic cables that you need depend on the type of optical
connectors in the device to which you are connecting the FAStT900 Storage Server.
If the device uses SFP modules or optical interface connectors, then you must use
LC-LC Fibre Channel cables. If the device uses Gigabit Interface Converters
(GBICs) as the optical interface connector, you must use LC-LC Fibre Channel
cables and LC-SC Fibre Channel cable adapters (Part number 19K1250) to connect
to the FAStT900 Storage Server.
Handling fiber-optic cables
Before you use fiber-optic cables, read the following precautions.
Attention:
To avoid damage to your fiber-optic cables, follow these guidelines:
v
Do not route the cable along a folding cable-management arm.
v
When attaching to a device on slide rails, leave enough slack in the cable so that
it does not bend to a radius of less than 38 mm (1.5 in.) when extended or
become pinched when retracted.
v
Route the cable away from places where it can be damaged by other devices in
the rack cabinet.
v
Do not use plastic cable ties in place of the provided cable straps.
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.
Using LC-LC Fibre Channel cables
The LC-LC Fibre Channel cable is a fiber-optic cable that is used to connect into
one of the following devices:
v
SFP module installed in a FAStT900 Storage Server mini hub
v
SFP module installed in an IBM Fibre Channel switch
v
SFP module installed in an IBM FAStT EXP700 drive expansion unit
v
Optical interface connector on an IBM FAStT FC–2 Host Bus Adapter (part
number 19K1246), IBM FAStT single port FC2-133 Host Bus Adapter (part
number 24P0960), or dual port FC2-133 Host Bus Adapter (part number
24P8053)
Figure 6 on page 5 shows an LC-LC Fibre Channel cable.
