Handling fiber-optic cables
Before using 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 connecting cables 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 snagged by other devices in
the rack.
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 shown in Figure 18, is a fiber-optic cable that is
used to connect into one of the following devices:
v
SFP module installed in an IBM FAStT EXP700 Storage Expansion Unit
v
SFP module installed in an IBM FAStT700 Fibre Channel Storage Server
For more information about cabling these devices, see the documentation that
comes with the LC-LC Fibre Channel cable.
Note: If you are connecting the FAStT EXP700 to an IBM FAStT500 or to an IBM
FAStT200, you must also use an LC-SC Fibre Channel cable adapter. You
also need the LC-SC cable adapter when connecting a FAStT EXP700 to a
FAStT EXP500. For more information about using the Fibre Channel cable
adapter, see “Using LC-SC Fibre Channel cable adapters” on page 26.
Connecting an LC-LC cable to an SFP module
Complete the following steps to connect an LC-LC Fibre Channel cable to an SFP
module:
