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 "HP 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
E8200zl, E5400zl, and HP E6200-24G-mGBIC yl Switches 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 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.
