Installing and Removing Fibre Channel Cables
WARNING: Data processing environments can contain equipment transmitting
on system links with laser modules that operate at greater than Class 1 power
levels. Never look into the end of an optical fiber cable or open receptacle.
Before installing an FC cable, see "Guidelines for Using Fiber Optic Cables"
on page 35.
To install an FC cable:
1
If applicable, remove the protective cap from the SFP module and store
the protective cap for future use.
2
Remove the two protective caps from one end of the cable and store them
for future use.
3
Insert the cable into an SFP module that is installed in the storage array.
The cable connector is keyed for correct installation. Holding the
connector, push in the cable until it clicks into place.
4
Remove the two protective caps from the other end of the cable and store
them future use.
5
Connect this end of the cable to one of the following devices:
• An SFP module that is installed in an FC switch port
• An FC HBA port
To remove an FC cable:
1
Press and hold the lever to release the latches before removing the cable
from the SFP module. Ensure that the levers are in the released position
when removing the cable. Do not grasp the SFP module plastic tab when
removing the cable.
2
On the end of the cable that connects into the SFP module or HBA, press
down and hold the lever to release the latches.
3
While pressing down the cable lever, pull the connector to remove the
cable from the SFP module.
