unable to connect

[aastratech]

Guiys,

aprreciate any suggestions..

customer has 3 Lim BC12 system.
Engineer noticed alarm that no back ups were possible as main i/o board NIU2 was blocked, tried rectifying this but no joy and all ports and would not allow connection to system, network port also failed to respond to ping test.
He was going to change the board but now the other NIU which allowed connection has also stopped allowing coneection to system programming and not rtesponding to pings..network is fine.
Big problem now is we have connection to look at alarms and dont know if reload will work
We have tried to button it but still same symptoms...
anybody suggest a fix???

1.
Did you reload LIM=1? (Poer off?)
2.
Make sure that you have same EIC code in the NIU board for dump (harddisk), if you swap NIU.
3.
Try to login on NIU port 1. That is the serial port upper most. Run it with 9600 b/s, 8 databits and No stopbit.
4.
NIU or NIU2?

HI, ONLY DID A RESET( BUTTON PRESS ONCE)
didn't do complete reload until i was sure back-up / data would reload..
tried all positions on NIU2 and port 1 on NIU no joy..

any help??

 

[aastratech]

guys,

removed NIU2 from system and tried to load in a 3lim test switch...NIU2 , no joy it has 31xx error so no reload looks like a NIU2 failure...is it possible to use another NIU2 with the same flash ? only issue is that the NIU2 will have a 02-0000 eic code ...
is there any other methods i can use??

 

[aastratech]

SORRY ERROR CODE ON LPU IS 50XX NOT 31XX

You can put a new NIU2 in your test Lim 1 and write EIC and load license to it, use the same flash and it will be ok in your live system.

parnum,

put a new NIU2 with correct eic and worked fine for a few days, the NIU2 is now back to system block and even with pulling the board i cant get it back in service.
Any ideas why this happens?? i can still connect with telnet session to other NIU in system but the system again has no back up and has tried to initiate a reload...help??

 

[parnum]

If you put NIU2 with flash in test lim, does it load ok? do you have your customer data on the flash?

When you put NIU2 in your live lim, it worked ok at first? did you dump the system twice? put it in your test lim.

If you can load from this latest NIU2 in test lim and see customer data, put it back in the live lim and push in LPU button then remove LPU from backplane and put back, and press LPU button again to force a complete reload from the NIU2 flash. Buttoning will only reload from BUP, you must take the power from the LPU.

Consider replacing the LPU in the live system with the one in the test Lim, maybe live data is corrupt or LPU is faulty?

managed to get pcregen data so I will load on another NIU2 and will try replacing the LPU...

Hi mdevo,

The NIU is known for blocking on excessive ethernet traffic.
I would suggest to remove the ethernet cables from ALL NIU's (if not possible, remove only LIM1 cable). and let the system run for a certain period.
- Check the network for broadcast traffic (arp requests, ...)
