voice gateway-removal of unused VWIC card

[lleweyiss]

I have 2 VWIC cards in gateway, one has no T1 connection, the other does have an active T1.  Can I remove the unused card without having to power down the gateway?

If I have to power off, is there anything I have to do prior to powering it off (cli commands or anything) ? I understand I need to make sure there is no traffic on the active T1.

Any other tid bits I should keep in mind to do this task?

not sure it matters, but I have a CUCM 7.02,

thanks in advance

Hello,

Cisco's recommendation is to turn off electrical power when replacing WICs on access routers.

What is your gateway model?

I have 2 gateways I am trying to remove unused VWIC cards from , one is a 2851 and the other is a 2821.

So to recap, 

I woudl do the following commands :

copy run start

write memory

And then I would power off,  remove card , install a blank plate, and power it back up.

(not on DC power, the cisco instructions above say not to remove power cord)

does this sound like it will keep me out of trouble   ?

You could do write memory or copy run start. Both commands do the same thing (i.e. they save the running configuration to start up configuration).

You may also want to check the config register by issuing the following command:
show version

The config register should be 0x2102

While you are there, take note of the IOS version the router is currently running

After that, you may want to check your flash to see how many IOS images there are by issuing the following command:
dir flash:

If I remember my CCNA stuff right, if you only have one IOS image in flash, you shouldn't need a boot statement. But if you have two or more, you will need a boot statement if you want to boot to a particular ios version.

Cisco, please correct me if I'm wrong

First of all the two commands above do the same thing, so only one would be needed.

Second, if the router is correctly maintained, no command is necessary because the configuration has been saved already.

Finally, even if no hot-swap is supported for VWIC cards, if you pull it out, nothing bad will happed. The worst can happen is router crash, that is in fact equivalent to power off and on.

I'm pretty sure you should power down to be safe.

If you power down, you should do save your configuratoin at the least. These commands should do it:

copy run start

write memory

Correct, none of the Cisco cards are hot-swappable. You need to shut down the router.
