Customer upgrading network switches. How to do a graceful switch

Customer upgrading network switches. How to do a graceful switch

Customer upgrading network switches. How to do a graceful switch

(OP)
The customer has a CS and 2 SS release 7.65 plugged in. A network upgrade is scheduled next week and the switches are going to be replaced. How can I make the process go smoothly and make sure the PBX is not impacted negatively. Should I shut down the servers first and then unplug them from the old switches? Any steps to follow?
Greatly appreciate any help. Thank you.

RE: Customer upgrading network switches. How to do a graceful switch

As its not going to be a power outage, then perhaps you shouldn't need to power off the Telephony equipment?.

I'd get a list of all the IP addresses and mark up the Ethernet cables as you will probably have both E and C LAN's on the customers network.

Generally speaking, the Call Server needs to be booted up and active first.

Check that the IP address's are able to be accessed OK.

Once that's online, then start off with the main Signalling Server and confirm that it's all OK.

Do the same afterwards for the other SS.

Finally, do the Call Pilot Server.

You might encounter problems with the ELAN configuration in LD 17 as it depends on the way they were built in the order that the IP devices boot up.

It's a good idea the grab all the IP information in case some of it is missed out by the IT department on their replacement switches if they are having to configure them from scratch.

Don't forget any host names in case the customers DNS Server is changing.

Thank you Firebird Scrambler. Any sequence of graceful shut down before the switches go down ?

RE: Customer upgrading network switches. How to do a graceful switch

It's been many years since I last touched the later CS1000 systems.

I'd probably do the shutdown in reverse order.

Call Pilot, Sig Servers, then call server etc.

Be wary of any IP cards in the call server as you might need to give them another reboot when powering up all the devices.
