gibbo_ap Posted September 17, 2009 Posted September 17, 2009 Do any of you use UPS's or surge protection on your network switches? Every power cut i poop my pants. just seems silly that no one ever installed them here before.
FN-GM Posted September 17, 2009 Posted September 17, 2009 We do. We put an APC 1500 rackmount on every switch
maniac Posted September 17, 2009 Posted September 17, 2009 My core switch has a duel power supply. One of these is connected into the main server room UPS to keep it running for a short while in the event of a power failure, mainly so the servers can still communicate with the UPS, as they all run network shutdown and rely on the switch for communication. On the rest of my cabinets, never seen the point. If there's a powercut then the network is useless anyway, and as for surge protection all my HP procurve switches have a lifetime warranty so no worries there Mike.
gibbo_ap Posted September 17, 2009 Author Posted September 17, 2009 ours all all warranty covered, so no real stress there. Its just a pain in the ass (and iminent me running to hide) when after power failure one dies and kills a room or two. (Happened 1st day back here wasnt popular that day)
pete Posted September 17, 2009 Posted September 17, 2009 We have a small ups in most network cabinets, it's the single most effective (price vs improvement) upgrade I've carried out here. Mind you, we're in a valley at the end of a long chain of overhead power, so our supply is probably flakier than most peoples.

(Happened 1st day back here wasnt popular that day) I've always got a couple of spare switches knocking about that I could swap out in an emergency situation.
gibbo_ap Posted September 17, 2009 Author Posted September 17, 2009 think it would be the easiest way to increase uptime, but would cost a lot. mmmm letter writing to the head i thinks
FN-GM Posted September 17, 2009 Posted September 17, 2009 We use ours to keep the phones up and running
User3204 Posted September 17, 2009 Posted September 17, 2009 We've just ordered 15 rack mount UPS exactly for this. As we have recently moved to VOIP someone suddenly mentioned to me that every time the power goes off we will lose the phone system.. ach ! Dunno what they're like yet, but they do remote access and SNMP. About £500 each.
localzuk Posted September 17, 2009 Posted September 17, 2009 We have them only on strategically important switches - ie. the core switch, and the switch used by our admin office. This ensures internet connectivity remains during power failures, as do our voip phones in the admin office (we don't need that sort of reliability for phones in random classrooms). Our cabs don't have enough space for much more in anyway...

Dunno what they're like yet, but they do remote access and SNMP. About £500 each. We lose the phone system anyway, as the switchboard is in one of the offices on the wall, and is hard wired in so couldn't really be put on a UPS. We have 3 emergency analogue lines in stratigic places through out the building for use when the power fails, these serve the purpose fine. Mike.
CraigM Posted October 5, 2009 Posted October 5, 2009 We have them in our core server cabinet and in the second computer room cabinet. These locations have our high end HP Procurves in them. The other cabinets in the school don't have space for a UPS as they are 4U high. Anyway, these switches are all ancient D-Link or Cnet switches, which we are slowly replacing. Once all the cabinets have Procurves in them, I'm not sure what we are going to do. Need to protect them but no space
webman Posted October 5, 2009 Posted October 5, 2009 Once all the cabinets have Procurves in them, I'm not sure what we are going to do. Need to protect them but no space Put the UPS on top of the cabinet if there's enough clearance?

timzim Posted October 5, 2009 Posted October 5, 2009 Put the UPS on top of the cabinet if there's enough clearance? Mmm, H&S.... Maybe also put a few pot plants on top of it and water them regularly, plus any old WW2 hand grenades you have lying around...
webman Posted October 5, 2009 Posted October 5, 2009 I know what H&S is I meant what H&S issues do you think that would pose?
timzim Posted October 5, 2009 Posted October 5, 2009 Most UPSs are pretty heavy (ours = 60kg) and therefore include fairly strong manufacturer recommendations that they are only mounted at the bottom of network cabinets. Mounting at the top will usually make the cabinet top-heavy and liable to topple over when pushed, crushing to death the user. Placing the ups loosely on the top of the cabinet therefore seems, imho, slightly less wise than than that bloke on TV who put a load of scorpions in his pants. Or did I misunderstand your post?
timzim Posted October 5, 2009 Posted October 5, 2009 Oh, the 4u cabs, fair enough. Still might fall on your head though?
webman Posted October 5, 2009 Posted October 5, 2009 (edited) Do you really need UPSs that heavy for a couple of switches? I was thinking more along the lines of the small desktop-type ones. Although, if your cabs are fixed to a strong enough wall using appropriate methods (4 huge bolts for each corner?) you could probably put anything on them Edited October 5, 2009 by webman
DMcCoy Posted October 5, 2009 Posted October 5, 2009 I'd be pretty uncomfortable putting anything as heavy as a ups in our wall mounted cabinets. While they are well secured it seems like an unnecessary weight. I only have ups for the core switches which are required for everything to shut down if power fails. I suppose some form of surge protection would be an idea, but no need for more than that really.
