Re: password recovery

Here are the steps:

1. At the console type " p". This will bring you to the pROBE+ prompt.

2. Type "nv 1". This command will dump the NVRAM informatation, which looks something like this:

NVRAM Section Information

NAME SIZE ADDRESS XSUMMED

CHKSUM 00000418 c0000000 Y

PSOS 00000100 c0000418 Y

BOOT 00000200 c0000518 Y

SYSTEM 00000100 c0000718 Y

DIAG 00001000 c0000818 Y

CFG 00000200 c0001818 Y

EVENT 00040030 c0001a18 N

PROBE 00000800 c0041a48 Y

3. Determine the address of the CHKSUM section (in this case c0000000).

4. Type "pm address data" where address is the address of the CHKSUM section and data is any non-zero value. In this example, you would type "pm c0000000 5".

5. Type "prb". This WILL cause a reboot.

After the concentrator reboots, the administrator password will be reset to the factory default.
