Core and MDF switches on UPS – Verify that they are on the battery backup device that is located in the rack.
Consider UPSs for the three edge switches - This will keep the switches on for a short period of time as well as all downstream Wifi APs that are powered via POE. A UPS will not mitigate long term outage events though.
Investigate why we had a Duplicate IP event –During a reboot, DHCP will expire all addresses and reissue leases to all devices booting up. It is possible during a short outage, a duplicate IP event can happen. In rare occasions a device’s circuitry would have stored power for a short period due to capacitance, thus holding on to its assigned IP. For this morning’s outage, we should not have had any dupe IPs since we were without power for 4 hours.
VOIP - If you hear that a phone isn’t working, they simply need to unplug it and plug it back in.

Update
We are continuing to investigate this issue.
Found that the following WiFI APs did not come back online cleanly. 2nd grade 6th grade Gym#2 Gym#3 This was due to duplicate IP address errors between the 4 WiFi devices. I remotely rebooted all four of the devices so that they get issued their new IP leases. This resolved the situation.
