The problem could be a incompatibility between the supervisor card used, the IOS version and its support for the GE module.

Hope the following chart with the minimum required supervisor/IOS helps.

Software support

With Supervisor Engine 2—12.1(19)E1

With Supervisor Engine 32—12.2(18)SXF

With Supervisor Engine 32 PISA—12.2(18)ZY

With Supervisor Engine 720—12.2(18)SXF

With Supervisor Engine 720 and WS-F6K-GE48-AF or WS-F6K48-AF PoE daughter cards—12.2(17d)SXB (WS-X6148-GE-TX only)

Can you post a "sh env/sh env power/sh power" (sorry i can never remember which one !!).

Also you are not running VSS are you ?


micoogullari Thu, 05/13/2010 - 07:54

Hi Jon,

thank you for your reply and guidance.

yes we are running VSS.

we installed the cards ot the two 6506-E  and we are facing the mentioned problem.

Jon Marshall Thu, 05/13/2010 - 08:03

You cannot run this card in a VSS system. You need all WS-X67xx modules in a VSS system, see the VSS Q&A for details of supported modules -



jorge.calvo Thu, 05/13/2010 - 08:07


That module is not compatible with VSS. See my VSS hardware details to have an idea:

2 x C6506-E running IOS 12.2-33SXI

SUP720 10GE

WS-X6748-GE-TX module

2 x WS-CAC-3000W power supplies.


francisco_1 Thu, 05/13/2010 - 07:44


Good you asked the question about VSS. Yep the 6148 will not work...
