Mini-GBIC Operation Notes
Revision “B” mini-GBICs only. This product requires ProCurve revision “B” or later mini-GBICs (product
number ends with the letter “B”, for example J4858B, J4859B). These switches do not support revision “A” mini-
GBICs.
Use only genuine ProCurve mini-GBICs. Non-ProCurve mini-GBICs are not supported. Use of genuine
products ensures that your network maintains optimal performance and reliability. Should you require additional
ProCurve mini-GBICs, please contact a ProCurve sales representative or an authorized reseller.
Hot Swapping mini-GBICs. The Gigabit-SX, Gigabit-LX, Gigabit-LH, and 1000Base-T mini-GBICs that you can
install in your ProCurve switch or mini-GBIC Module can be “hot swapped”—removed and installed after the
module is installed in the switch and receiving power. You should disconnect the network cables from the mini-
GBICs before hot swapping them.
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 Gigabit-SX, Gigabit-LX,
Gigabit-LH, and 1000Base-T 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.
