On wednesday when working at our food bank warehouse in Talpiyot we had a power cut.
Quite sudden, I was working on setting up a server on my work bench which suddenly went off. It wasn’t running anything important. A repeated beeping came on from the various UPS (battery back up) units around the building. One of them I rebuilt myself as the batteries were old and no longer functioning, each of the cells has a life span of 3 years or so. I am glad I did now.
With multiple circuits around the building, with the sockets labeled for computer use, it seems everything went to plan, apart from the lights going off in my workshop (one of the only rooms with no natural light) and the video intercom system on the front door. I had to manually power down the servers and tell everyone to quickly save their work and shut down their PCs. Meanwhile our giant walk in freezer had its own battery system, so no food that was to be supplied to the poor got spoiled.
After the utility company was called, we were told there could be a wait of 2 hours. I think the power outage ran for about 45 minutes, this meant the electric water heater built into a water bottle dispenser was still hot enough to get two cups of tea each. Once the power came back on, I manually powered on four PCs in my workshop and the two servers and all seems to be fine. Oddly enough, some switches and routers were still blinking away protected with a shoebox sized UPS but we had no internet connection, although I could ping our router. It seems during the hotter months, more people have their air conditioning on and the electricity supplier may not be able to cope. It seems all companies I have seen in Israel all have UPSes on PCs and critical equipment, often see them underneath a cash register in a shop. If this sounds like a big concern, now that I have been here a year, this is the first time I have seen a power cut at one of our offices.
I want to look at means of monitoring our bigger UPS units remotely, we have some APC and some lesser brand units, so I can see sources of problems from my main desk.
