If it were me, and the NAC is running at all, I'd try to restore defaults and then update the code. Not sure if it was DSP, ARC, or NMC, but I recall one software update for something along the way fixed a reboot problem with something. Worth a try. If you get really frustrated, you could always send it to me. If I find that it doesn't work, I can throw it away for you. Of course, if I can get it working, you'll never hear from me again! :-) - Joel -----Original Message----- From: Lee Terrell [mailto:leet@directcon.net] Sent: Monday, December 23, 2002 9:15 PM To: usr-tc@mailman.xmission.com Subject: Re: [USR-TC] Strange DSP NAC activity Well, I now have all 14 DSPs split between the 2 HiperARCs just for an initial configuration, the the suspect DSP NAC is now resetting itself in slots 11-14, so that's all of them. I am now guessing it's a faulty NAC since I've been able to try other NACs in the slot and get a PRI up successfully. Just for mention, the card in question is hardware version 0.54.0 with software version 2.0.51 in case someone knows any tricks to try, but I really doubt there will be any fixes I can try since 6 other NACs are the same version and they all run normally. -Lee Lee Terrell wrote:

I'm digging deeper into the configuration now. It seems that slots 1-10 at statically assigned to one HiperARC and slots 11-14 aren't assigned anywhere, statically or dynamically.

The chassis does have 2 130A power supplies, but I only have one plugged in for now.

If the last for slots aren't assigned at all, would that account for a possible faulty DSP NAC not resetting periodically in slots 11-14? I'm printing out some pdf file now to read some more. This is my first crack at a unit with multiple ARCs and power supplies.

I should be a little better educated when I get through a few of these chapters. Thanks for the initial pointers on what to look for.
