Help with BayStack 450-24T

Archived from groups: comp.dcom.lans.ethernet (More info?)

Hi, I need to reset the password on a BayStack 450-24T - the original
password has been lost/forgotten. I believe that there is a reset
possibility by using some hash on the mac address. Can anybody give me any
pointers please.

Please reply to the group and cc to

Thanks

Thanks Walter, I'll give that a try tomorrow and report back. I'll use a
Wyse 85 BTW.

There is also a backdoor password, but it is tied to the MAC,
and the algorithm is not publically known. Nortel will only release
the password if you have a support contract, according to people who
have tried.
