V2 (V2H124-24) password recovery


I lost the admin passwords of two matrix V2 (V2H124-24).

the MACs are: 00-01-F4-45-1A-C0 and 00-01-F4-44-FE-60

How can I do password recovery?

I believe GTAC had to generate a backdoor password for it but the switch is no longer supported.

was this the BIOS password? We have some VHs in storage we need to wipe before sending to surplus

Do you know how to enter a BIOS or boot ROM or similar on the V2 switches?
tiger/tiger123 does´nt work (I remember it works on the VH-series)

any other ideas?

Hi,

there is a GTAC Knowledge article describing the procedure mentioned by Curtis: Password Recovery for the Matrix V2. But as I understand it, GTAC no longer provides the backdoor password, see How to recover password on a Matrix V2. 😞

Is it possible to access the boot ROM, and boot to factory defaults from there?

How about Extreme publishes how to compute the backdoor password for these old, out-of-service switches, to enable the owners to help themselves? The GTAC Knowledge site would be a good place for this.

Edit: Sadly, the Matrix V2 switches we once had have been thrown away, so I cannot try anything out.

Thanks,
Erik
Hi,

we don´t know how we can access to the Boot-ROM.

login with admin/password does´nt work - but we can login with guest/guest - but if we will "configure" the switch ask for password.

any ideas for password recovery / backdoor password?
