The switch supports two types of GBICs: the Parallel ID GBIC and the Serial ID GBIC.
The system uses identifier bits to determine the media type for the GBIC that is
installed. Initial ExtremeWare versions do not support Serial ID GBICs. If Serial ID
GBICs are installed in a switch with an initial software release, the switch will not bring
up the link on GBIC ports.
GBICs are used in these switches:
•
Summit1 switch
• Summit24 switch
• Summit48 switch
• Summit7i switch
The Summit1 switch cannot read Serial ID information. When the software tries to read
the media type for the 1000BASE-SX Serial ID, and the 1000BASE-LX Serial ID GBICs
on these hardware platforms, the software displays “Unknown” for the media type. In
that case, you can determine the GBIC media type by removing the GBIC from the
switch and looking at the GBIC label.
