cisco 3550 gbic problem

hi

i have a catalyst 3550. i hev also a gbic

i have put the gbic in a frre slot and on boot i have

00:00:34: %GBIC_SECURITY-4-VN_DATA_CRC_ERROR: GBIC interface Gi0/1 has bad crc

00:00:34: %PM-4-ERR_DISABLE: gbic-invalid error detected on Gi0/1, putting

Gi0/1 in err-disable state

my gbic is :

cisco systems 30-0759-01 1000BASE-SX.

i have tried to upgrade ios to the latest version without results.

Why on another catalyst 3500 the gbic seems work well?

bye

Re: cisco 3550 gbic problem

yes i have sent gbic to a friend. he say that no errors on boot, but gbic seems a lx type..... it seems strange.

i have read your link and gbic seems to be not supported...

my model of gbic is 30-0759-01 1000BASE-SX.

note: i have open a case with tac and i have uploaded the new ios. how can i see if gbic is supported for my model?

thank you.

Release- note can tell you if the GBIC is supported or not. By the way, LX is supported

Thanks for pointing, It is not updated, it is not even showing Cat6000- It is always best to check the release note.
