Line card issue? 1

[altolabado]

Is there any way I can tell what TN is coming from what line card.
And if there is an error with the Tn, in what situation will the line card have to be pulle dout and put back in.
Can this be done just like that, or does something have to be deactivated?
Can I see some indication on a line card that is not working? (red light)

Thanks.

The TN tells you which card it is. In large systems (51-81C) the TN is formatted as Loop Shelf Card Unit

For example. TN 012 0 05 11
Loop 12, Shelf 0, Card 5, Unit 11

In Option 11's it's just Card 0 00 Unit, so 009 0 00 11 would be Card 9 Unit 11

To remove a card, use LD 32 to disable it first.

>LD 32
REQ: DISC 012 0 05

Take the card out, replace it, or reseat it, then re-enable it in LD 32 again.

>LD 32
REQ ENLC 012 0 05

If there is a red light on the front of the line card, then it is disabled. You can try to enable it in LD 32. If all the cards in an IPE module are disabled, then most likely the loop that controls that module is disabled as well. You can use the ENLL command in LD 32 to enable a loop.

LD 32 also has the STAT command which you can use for loops and cards. If you use STAT 12 0 5, then it will stat the card, if you use STAT 12, then it will stat the entire loop. In Option 11's, just STAT 12 will give you the status of card 12.

Hope that helps.
