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
