Hub Problems….?

We have around 10 hubs that have management modules in them. Our problem is
that a couple of them have half the ports shut down by the management
module. I believe my predecessor had experimented with the telnet
capabilities of remote management on these hubs and locked them up. I have
HP Advance Stack Assistant software. Here’s the hardware:

HP Switching Hub-12R (HPJ3200A)
10BT Management Module (HPJ3210A)

He didn’t give me the password. Question: Does anyone know how to reset the
module or a way to override the module’s security using a direct (RS 232)
connection? Any ideas would be greatly appreciated…
