When a Library's entire network is completely down, the first troubleshooting step is to restart the network equipment.
On all of our network racks,
a "UPS" supplies the electricity to all of the equipment on the rack, including the router.
Turn the UPS off and back on, and all of the equipment goes off and back on.
Most of our routers are plugged into a UPS device, which keeps supplying power to the equipment in case of an outage for 10 to 15 minutes. It's the easiest thing to find and the easiest place to switch off the power to the router. Just turn the switch in front off, make sure all the lights on the equipment go out, wait about 10 seconds, then turn the switch back on.
It will take the router from 90 seconds to 3 minutes to reconnect with the Internet. Sometimes, cycling the router a second time is necessary when the first time doesn't solve the problem.
While waiting for the router to come back up, it's an excellent time to run a continuous ping to the gateway, to see if and when the network connection is reestablished. To do this, open a Command Prompt, and type "ping -t 10.212.xx.1" where "xx" is the number that is specific to your Library's gateway. (See the list of gateways for your Library's number.)
