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) is now supported under the
G.07.xx or later switch software version for any of your HP ProCurve Series 4100gl Switches.
Using Trunking with the Gig-T/GBIC gl Module
Valid trunking configurations using this module differ from those described in the Management and
Configuration Guide shipped on the documentation CD that came with the switch, and the online
Help provided in the console and web browser interfaces.
The trunking grouping for the Gig-T/GBIC gl Module is as follows:
Group1: 1-5, 7-11, 16
Group2: 6, 12-15, 17-22
Trunk groups must be created with ports from the same group, Group1 or Group2. See the HP
ProCurve Switch gl Modules Installation Guide for more information.
Release G.07.41 (or greater) of the switch software is required in the HP ProCurve Series 4100gl
Switches to support the HP ProCurve Gig-T/GBIC gl Module (J4098A).
Stack Management Issue
One of the features available on your Series 4100gl Switch is Stacking. You can connect up to 16
switches together to form the stack, and then manage them all through a single IP address. The switch
that has the IP address is designated as the stack commander, and the other switches are configured
as stack members and are accessed through the commander.This feature is also available on older
HP ProCurve Switches including the Switch 1600M, the Switch 2424M, the Switch 4000M and Switch
8000M, the Series 2500 Switches, and the Switch 4108gl and Switch 4108gl Bundle that are running
operation system version G.04.04 or older.
The problem. The older switches use a version of the feature that does not recognize your newer
Series 4100gl Switches, but only when you use the switch web interface to perform your stack
management. (A "newer switch" is any such switch running operating system version G.05.xx or
later). If one of the older switches is configured as the stack commander, when you try to access a
newer Series 4100gl Switch by selecting it in the Stack Access field on the web interface screen, you
will get an error. The newer switch image will not be displayed.
