Read Me First - gl Mini-GBIC Module (J4893A) G.05.xx or greater

Connecting the mini-GBICs to Devices with Fixed Configurations. For some older network

devices, including some older HP Procurve devices, the default for the Gigabit-SX and -LX 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.

Gigabit-LH mini-GBIC Support. The Gigabit-LH mini-GBIC (J4860A), which is supported on the

HP Procurve 9300 Routing Switches, is not supported under the G.05.xx or earlier operating system

version for any of your HP Procurve Series 4100GL Switches. Contact your HP representative or

check the HP Procurve web site for availability of support for this mini-GBIC type.

Saving the Configuration After Installing or Exchanging a Module

The following cases automatically result in a change to the running-configuration on your switch:

If you replace a module with another module of a different type and then reboot the switch

If you install a module in a slot that has not previously been used (including when you install

a module and apply power to the switch for the first time)

If you replace a transceiver or mini-GBIC in a module with another transceiver or mini-GBIC

of a different type.

If you want to save such changes to permanent memory (startup-configuration), use the write memory

command in the switch console. This causes the switch to use the current hardware configuration

after subsequent reboots. (The switch always reboots from the startup-configuration.)

If you do not save hardware changes to the startup-configuration, you will be prompted with the

following message (to save the configuration) the next time you use the reboot or reload commands,

or if you move from the CLI to the Menu interface in the switch console:

Do you want to save the current configuration [y/n] ?

Note that if you exchange module types in a slot and reboot the switch, but do not save the

configuration, you can restore the switch to its prior configuration state by re-installing the original

module type in the slot and rebooting the switch again. This is because the switch operates by using

the running-config, but reboots from the startup-config.

Replacing a module with another module of the same type in the same slot does not affect the switch

configuration and it is not necessary to save the configuration.

For more information on switch memory, including the startup-config and running-config memories,

refer to the Management and Configuration Guide on the Documentation CD-ROM included with

your switch. For the latest version of HP switch documentation, visit http://www.hp.com/go/
