Installing the Switch
Installation Procedures
Removing the mini-GBICs:
N o t e
You should disconnect the network cable from the mini-GBIC before removing
it from the switch.
Depending on when you purchased your ProCurve mini-GBIC, it may have
either of three different release mechanisms: a plastic tab on the bottom of
the mini-GBIC, a plastic collar around the mini-GBIC, or a wire bail.
To remove the mini-GBICs that have the plastic tab or plastic collar, push the
tab or collar toward the switch until you see the mini-GBIC release from the
switch (you can see it move outward slightly), and then pull it from the slot.
To remove the mini-GBICs that have the wire bail, lower the bail until it is
approximately horizontal, and then using the bail, pull the mini-GBIC from the
slot.
