Replacing a Fibre Channel Tape Controller When a Fibre Channel Tape controller fails in an online active system: 1. Perform a normal system shutdown of both the Fibre Channel Tape controller and the server or servers. 2. Remove the Fibre Channel cable connector from the failed Fibre Channel Tape controller. 3. Remove the SCSI cable connectors from the Fibre Channel Tape controller. 4. Replace the failed Fibre Channel Tape controller.

installed one way because the GBIC and the guide rails inside the Fibre Channel Host Bus
Adapter receptacle are keyed.
3.
Install the Fibre Channel cable connector into the receptacle on the GBIC. The GBIC and
the Fibre Channel cable connector are keyed to prevent an improper installation.
Replacing a Storage Hub 12
When a Storage Hub 12 fails in an online active system:
1.
Perform a normal system shutdown of the Fibre Channel Tape Controller, Storage Hub 12,
SCSI devices, and the server or servers affected.
2.
Remove the Fibre Channel cables and associated GBICs. GBICs and cables may be
removed together with normal handling precautions.
3.
Replace the failed Fibre Channel Storage Hub with a known good unit.
4.
Replace the GBICs and associated Fibre Channel cables.
5.
Connect the power cord and perform a power-on self-test. Normal operating mode will
