Password Recovery For Brocade Silkworm 3900

Hi,

I have a silkworm 3900 that I purchased off ebay. I do not have the passwords for it. How do I go about obtaining the password recovery firmware? I do not have a support contract. Are there any other ways to reset the silkworm to factory defaults. I am surprised that it is so difficult to reset the password to factory defaults...

Any help would be appreciated

There are root, admin, and factory accounts by default. Have you tried all three of them?. I believe the factory password is obtainable on the web somewhere.

Luckly the prom password was never set and I was able to use the instructions found here:

In case that link goes away, the paper is intitled:

Hi,

We already gone through this document but after giving the boot command with that syntax its going to init level 3.
I think this document is only for V2, V3, V4, V5 but we need V6.1.

Before you begin with Recovery Procedure,, have to Identify the Switch Type.

NEW Switch Model, 300; 5100; 5300 and so on, are U-Boot based, and you neet here another procedure.

I have inserted in the preview post a DOC, that alow you to check the Switch Type.

FOS pwd recovery is not only based by FOS Release , but at Switch Type.
