ONS 15454 shows up as "unknown" after power outage

[Colin Higgins]

We had a power outage that took down a ONS 15454 in a remote facility. Upon restoring power and powering-up the unit, it shows up in CTC as grey with "Uknown2" as the name.

I had someone reseat the TCC card, but it still comes up as unknown.

Has anyone seen this? Any suggestions (the device is hours from me)

You can try to delete the DCC or OSC, then recreate it.

Try and restart CTC session and clear CTC cache

Can you ping the node

Check to see if the node is in the OSPF routing table

Can you access via CTC locally

Is your CTC terminal directly connected or does it go via a firewall

Probably resolved now how did you resolve it?

It ended up coming back after resetting the TCC card.

chris: out of curiosity, how do you clear the CTC cache?

When you launch CTC a screen appears which gives details of the Java Enviroment and there is a button on the screen which is labeled "Delete CTC Cache"
