6.3.1 Removing an Interface Board
Note – It is not necessary to remove the interface board from the card cage to
remove and replace GBICs. A GBIC may be removed and replaced "live" (without
removing power from the system or board). However, the necessary software
precautions must be taken whenever the I/O path to a particular disk is to be
interrupted; halt all I/O activity to the disk affected by the replacement of a GBIC.
To replace a GBIC or fiber optic cable, proceed to Section 6.3.3 "Removing a GBIC."
1. Unfasten any fiber optic cables from the board front panel and set them aside
