Gb Pass-through Module

Gb Pass-through Module Link Negotiations

A Gb pass-through module external port negotiates a link with an external device whether a server
module is installed or not. This is because the Gb pass-though module uses the SerDes interface
for internal connectivity to the server modules.
NOTE:
The Gb Ethernet module must be connected to a 1000 Mb port on the external switch (10 Mb and
100 Mb ports are not supported).
The following cases describe normal behavior of the Gb pass-though module when a cable is
connected from an external port on the module to an external switch.
• A link is displayed at both the external switch and at the Gb pass-through module if a server
module is installed or a Gb Ethernet daughter card is installed in the server module.
• A link is displayed only at the external switch if a server module is not installed or a Gb
Ethernet daughter card is not installed in the server module. A link is not displayed at the Gb
pass-through module.
