Hello again, all. I've got a serious problem with a TNT (referenced in a previous posting). I've received no reply from Lucent's engineers on the matter. Following is the exact description I sent to them. Please tell me if A) you know what is wrong; and, B) if you can understand it, which would let me know why Lucent hasn't responded. :) Our building had lost power the other night, and everything was running on UPS's. We were able to safely shut down the TNT. When trying to bring it up, only the controller card, a fast ethernet card, and 2 t1 cards came up. (slot 17, 2, 3, and 4 respectively). The HDLC-2 cards in slot 4 and 5 would not pass POST. I took 2 madd cards from another tnt that was having no probs and put them in slot 6 and 7; they also would not pass POST. I removed one of the working t1 cards from slot 3, and put an HDLC card in that slot, and it still would not pass post. I reloaded the tntsrb.bin and tntrel.tar files (ver 8.0.1), and no changes. I also swapped controller cards with a working tnt to no avail, and tryed a different flash card (fsck said both cards were good). The error shown is SAR: Failed external loopback POST. In summary, the controller card seems good, the flash card semms good, all cards seem good. I can't point a finger at the chassis, because when I swapped the upped t1 card for the hdlc card, the hdlc wouldn't come up. The HDLC cards come up fine in a different TNT. As an addendum. I recently found out that the UPS's were not meant to do what had been happening. Apparently, a fuse blew in one of the electric company's boxes outside, which knocked out a phase of power into our building. Our transformers require three phases, and was only receiving two. The TNT's were shut off after 30 mins of recieving odd phased power. Any information into this would be most helpful as well. Gene Schwab Network Bob @ Telscape Communications P.S. If you can help me with this, I might even let you beat me in Counter Strike. ++ Ascend Users Mailing List ++ To unsubscribe: send unsubscribe to ascend-users-request at bungi.com To get FAQ'd: <http://www.nealis.net/ascend/faq>
