For supported platforms and minimum software requirements to support this
product, see the document titled "Support for the J8177C 1000Base-T Mini-
GBIC" on the "ProCurve Mini-GBICs and SFPs" Manuals Web page.
The J8177C Gigabit copper mini-GBIC is not supported on dual-personality
ports.
The J8177C is capable of 100 Mb operation. This is supported on only the
HP ProCurve Switch 8200zl, 5400zl, and 6200yl Series using software
version K.12.21 or later. Use the "auto-100" port setting to enable 100 Mb
operation.
Important: The earlier J8177B does not support 100 Mb operation.
When used in the ProCurve Switch gl 20-Port 10/100/1000 Module
(J4908A), the J8177C mini-GBIC can be installed in either the upper or
lower mini-GBIC port, but will block access to the other port.
