(usr-tc) How many is too many?
Does anyone know what the limit is for the number of HiperDSPs you can use in a TotalControl Chassis with 70 amp power supplies? The chassis that I am loading currently has 10 HiperDSPs and 2 HiperARCs. I appreciate any recommendations. Thank you.

Mike, According to 3Com that box with 10 DSP and 2 ARC's would be maxed out. I currently have some 130 dc power supplies in stock if they will work for you. At 02:23 PM 4/10/00 -0500, you wrote:

I'm at 12 DSP's, with two 70AMP PS's. People at 3Com I've talked to said that's fine, adding the more hi-po equipment causes more of a drain. __________________________________ Justin Ellison System Administrator InternetUSA sysadmin@nebi.com http://nebi.com 800-603-3502

Thus spake David DenHollander

Actually, my understanding was that it would be maxed out with a *single* 70amp PS. You can run a full 14 DSPs and 2 Arcs and NMC with 2 70amp PS's, but you loose the fail-safe capability...if you loose a single PS, you loose the whole chassis. A single 130amp will run a whole chassis without problem, so dual 130's give you the fail-safe capability with a full chassis. -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456 - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

I have been running with 11 HDM's in my ARC chassis for a very long time. 11 makes it nice because then you can get 253 modems with PRI's which fits nicely into a /24 pool. - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

I run a perl script that checks the call failure rate of the modems on our HiperDSP. It shows that 6 of the 24 modems on one card have a failure rate of over 50%. Any ideas what might be going on and is there any way to disable these modems? Thanks!

If the number of calls/failures is fairly low on the modems, I wouldn't worry about it as it's fairly easy to get 5% or higher failure rate until you get a few hundred calls or more. If they're obviously hung pairs, here's how to soft busy them; In TCM, highlight the top set of lights on the desired DSP, then select configure-actions/commands. Select "Timeslot", then highlight the desired modems. In the command window, choose "software" and "soft busy out", then click "Execute". Normally what I do is soft-busy the bad modems through peak evening periods, then busy out the whole card later, when usage starts dropping off. By morning, the card is empty and I can reset it. -- Kirk Mitchell-General Manager mitch@keyconn.net Keystone Connect Unlock Your World Altoona, PA 814-941-5000 http://www.keyconn.net - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

Failures are running between 54% and 91% and they are pairs. Thanks for the info on "soft busy out". Is there a fix for this problem?

Anyone know if there is a support list for 3Com switches? I'm having a terrible time trying to get this stupid S400 Pathbuilder to switch from AMI encoding to B8ZS. It refuses to take the setting. Anyone? -Ken - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

I'm not sure what the official recommendation is but, considering that you've got 2 power slots to feed 17 card slots, I don't think I'd feel comfortable filling more than 10 or 11 slots on a single power supply. Especially if it was a 70amp one. -- Kirk Mitchell-General Manager mitch@keyconn.net Keystone Connect Unlock Your World Altoona, PA 814-941-5000 http://www.keyconn.net - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
