Mini-GBIC Operation Notes
Revision "B" or later mini-GBICs only. This product requires revision "B" or later mini-GBICs (product
number ends with the letter "B" or later, for example J4858B or J4859C). These switches do not support revision
"A" mini-GBICs.
Use only genuine ProCurve mini-GBICs. Non-HP ProCurve mini-GBICs are not supported. Use of genuine
products ensures that your network maintains optimal performance and reliability. Should you require additional
HP ProCurve mini-GBICs, please contact a ProCurve sales representative or an authorized reseller.
Hot Swapping mini-GBICs. The mini-GBICs that you can install in your HP ProCurve switch can be "hot
swapped" — removed and installed after the switch is receiving power. You should disconnect the network
cables from the mini-GBICs before hot swapping them.
Best practice tip: After inserting a mini-GBIC into a switch, the Mode LED will be on for two seconds while the
mini-GBIC is initialized. Do not remove the mini-GBIC until the Mode LED has turned off. For the 2600 and 2800
switches: After inserting a transceiver into a 2600 or 2800 switch, the "M" LED will come on to indicate that the
mini-GBIC slot is active. Wait at least two seconds after the "M" LED comes on, if you need to remove the
transceiver.
When you replace a mini-GBIC with another mini-GBIC of a different type and then execute the write memory
command in the switch console, the switch configures the port on the new mini-GBIC with the default mode
(speed and duplex) settings used for the new mini-GBIC type. The default mode for the mini-GBICs is Auto. Note
that the switch retains other port-specific configuration settings, such as trunking, Spanning Tree Protocol (STP),
and VLAN values that were configured for the previous mini-GBIC.
Connecting the mini-GBICs to Devices with Fixed Configurations . For some older network devices,
including some older ProCurve devices, the default for the Gigabit-SX, Gigabit-LX, and Gigabit-LH ports is a
fixed configuration, for example 1000 Mbps/Full Duplex, or is otherwise different from these default configura-
tions for the mini-GBICs, which is Auto. As a result, those devices may not connect properly to your mini-GBIC
port; you will not get a link. Because of these default configuration and full-duplex considerations, for best
operation, you should make sure that the devices connected to the mini-GBIC ports are also configured to Auto.
At a minimum, make sure the configurations match.
