Gah! I've got 6 chassis' with dual ARCs, and HiperNMCs, 14 DSPs in one location. All the latest TCS4.5 code. However, one of the chassis's is giving me a red "hub status" on the NMC. The chassis runs fine, otherwise. I've tried swapping out the NMC, rebooting, firmware upgrades, etc... it stays red. Actually, it goes red a few seconds after the NMC gives a console on the RS232 port. This is a _real_ basic question. How do I find out what is causing this? I've looked in the TCM and I'm pulling my hair out, as I am stumped. Any thoughts? ----Steve Stephen Amadei Dandy.NET! CTO Atlantic City, NJ
Check the fans...make sure all are spinning. I had a hub status light go red because one fan went belly-up.

Ah... totally forgot about that. I'll check it next time I'm there... though it's stacked tight, so I have no idea how... ;-) ----Steve Stephen Amadei Dandy.NET! CTO Atlantic City, NJ

The fan trays are removeable. At the front, there are two screws, one on each side, pointing sideways, unscrew those, then pull...hard. The whole fan tray will slide out. There may be a couple of screws in back holding it into place as well, so check those. -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456

Don't forget to release the third screw, on the chassis' back end. -- [.........]s Marcelo Marchesoni rede1@linkway.com Sao Carlos - SP - Brasil
If you highlight the nmc and go to performance...failure reasons...it should tell you why the alarm light is on.
