We came back from the Christmas break to find that half the computers in the bank couldn't get on the network. Joy.
At first, we thought it was the T1 to our main office, but after resetting that connection, I noticed that the connection lights on one of the switches were all orange. I cycled the power to it, although I didn't expect that to help, and still nothing.
Luckily, there were a few open ports on the other switch, so I moved those network cables that we absolutely needed to the other switch. But only half of us are here this week, and come Monday, we're going to need another switch. I emailed our IT guy at the main branch and explained the situation. He ordered us another switch, which should be here Friday.
We didn't figure out until this morning that our VOIP connection to the main office was down. At first, we thought it was the T1 again, even though everything else was working. Then I realized that the phone system must be plugged into the dead switch. I tracked down which network cable it was, and sure enough. I found something that could be temporarily unplugged from the working switch and plugged the phone system in there.
What a fun bit of troubleshooting. They don't pay me enough for this.
ETA: My husband just said he should have bought me a pocket protector for Christmas.
