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 configurations 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.
