Can someone please tell me how to reset a Larscom CSU/DSU unit back to default settings? A former employee has set a password on the device and we need to get in to so some tweaking on the unit for troubleshooting purposes. Does anyone know how to do so?
I have searched high and low on the internet. The easy thing to do would purchase a CSU/DSU card, but we are not allowed to do so...Have you tried contacting the manufacturer for support? Or, look for a manual on the device....I'm not familiar with these devices but maybe there is a BIOS FlASH available from the manufacturer........That will most likely rid the old password...

even if it is the SAME BIOS version, FLASHING the BIOS will could rid the old password, as Flashing a PC motherboard would do the same.Believe me, I have contacted the manufacturer and have looked to the end of the internet with no luck... this is my last hope before I take this unit out to the parking lot and run it over with my truck. Is the CSU/DSU a card in a computer, or it's own unit?
Since this involves circumventing a password i'm afraid we are limited in what advice would be proper to give...
Since also it was done by a former Employee why would you not be allowed to BUY the card to rectify the ISSUE ? ?

I think there may be more to this story...It is its own unit.

PATIO - Since I am not in charge of our budget and we are not allowed to purchase any more equipment, I have to make use of what we have. Trust me, I would rather just purchase a new router with a CSU card. I am not a hacker or trying to circumvent any security. Any attempt by me to do so, would cause me to lose my job and security access. The former employee was actually a contractor and I am a state employee.I am slab's counterpart, we've called verilink (ctdi) who bought out larscom. They emailed us a reset that doesn't work on that model CSU/DSU, so we called again, the engineer said that he was going to get one of those models and play with it then call us back. Haven't heard back from him. As for the former employee, we've tried to contact them, but where there contract wasn't RENEWED, well take a guess.
