I am getting a recurring situation where the chassis stops taking calls and
gives a fast busy signal.
I have reported this issue to commworks' technical support but the
technician said that since I was running a chassis with more than 5 PRI with
dual 70amps, they could not guarantee anything. I would need to use 130Amps
and he swiftly emailed me the 3com info bulletin about power consumption on
the chassis ...
I am hoping someone on the list could help me:
The problem affects mostly the chassis that receives most calls (i.e. the
one at the begining of the call queue). It used to happen once in a while
but it now happens daily.
Inventory:
A chassis with dual 70amps, 1hiper arc(5.1.99-8 128Megs), 11 DSP's(2.1.9 PRI
5ESS)
the Arc is running ospf and using an IP pool of 260 IP's
Symptoms:
I checked the syslog files and noticed that at the time of the incident, the
Harc sends the following logs:
** Message: At 09:33:42, Facility "IP", Level "CRITICAL":: Deleting IGMP
network before finally freeing dynamic network IPpdb
** Message: At 09:34:18, Facility "IP", Level "CRITICAL":: Deleting IGMP

[...] (Previous message was repeated 10 times)
** Message: At 09:38:48, Facility "IP", Level "CRITICAL":: ip_fwd_get_opt:
no IP address available for dynamic address assignment
** Message: At 09:38:48, Facility "IP", Level "CRITICAL":: Deleting IGMP
network before finally freeing dynamic network IPpdb
** Message: At 09:39:04, Facility "IP", Level "CRITICAL":: ip_fwd_get_opt:
no IP address available for dynamic address assignment
[..] (Previous message was repeated several times)
I then noticed that an OSPF cisco neigbor complained that the interface on
the HARC went down:
** Message: 85194: May 18 13:42:23.095: %OSPF-5-ADJCHG: Process 1, Nbr
xxx.xxx.xxx.xxx on FastEthernet0/1 from FULL to DOWN, Neighbor Down: Dead
timer expired
At this point, all dialup customers have been disconnected from the DSP's on
the chassis
And I see the following syslog message from HiperArc:
** Message: At 09:43:23, Facility "Configurator", Level "INFORMATION"::
HiPer system configuration complete at 5/18/2001 09:43:23
Doing a "show board crash" shows that a crash happened at 5/18/2001 09:41:43
============================
- I don't think this is related to the number of cards in the chassis
because I've seen this happen with another chassis loaded with 7 DSPs
- I've tried several HARC codes. All 5.x.xx crash
- The DSP's show LocalOutOfService or RemoteOutOfService on most of the PRI
channels. The only way to restore them is to reboot the DSP.
