Mini-GBIC Operation Notes
Revision “B” and “C” mini-GBICs only. This product requires ProCurve revision “B” or later mini-GBICs
(product number ends with the letter “B” or “C”, for example J4858B, J4859C). 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
productsensuresthatyournetworkmaintainsoptimalperformanceandreliability. Shouldyourequireadditional
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 ProCurve Switch can be “hot
swapped”—removed and installed after the switch is receiving power. Youshould 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 new mini-GBIC type. The default mode for the mini-GBICs is Auto. 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 Gigabit 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.
