6.3.4 Installing a GBIC
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.
Ensure that the orientation of the alignment groove is correct ( ) and then
