Author Topic: best practices Jack Ondracek Film God Posts: 2348 From: Port Orchard, WA, USA Registered: Oct 2002 posted 07-22-2019 03:30 AM                        Years ago, we used to debate whether to leave tube-type equipment on 24/7 or power it down when not in use. At various daytime-only radio stations, we'd leave the tubes lit overnight, and then we'd try powering them down. In all cases, there were people who were completely convinced you should do it one way or the other. In the end, I found that leaving tubes lit for equipment that tended to exhibit temperature drift over the time it took to fully warm up seemed to make sense. Otherwise, tube life vs electric expense seemed more or less a wash. I've heard it said that we should never turn off the servers, the projectors, our various PCs, and various combinations of them all. I've tried it and, again, it doesn't seem to make much difference either way. On average, my equipment is actually productive about 4 hours a day. So... instead of leaving it running, uselessly, for the other 20, I power it all down... everything. After I gracefully power down my servers, I remove their power, as well as to the projectors, by shutting off their respective UPS. Then, I pull the breakers. The stuff is powered off cold. My projectors have been reliable... my drives last about 4 years and my UPS batteries, about 5. Both are on replacement schedules. All of it seems to be fairly predictable. We do the same with the PCs that run our music automation, audio processing and POS stations, with no ill-effects that I can identify. Every night... boot up from scratch, run the show, then power them back off. Just doesn't seem much of a big deal to me... do what makes sense to you.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 07-22-2019 07:33 AM                     Jack If you’re only using the equipment 4 hours a day, it may be well worth switching it off when not in use. The money saved on electricity will well compensate for a broken hard drive after a number of years. The recommendations you find online should be evaluated on a bigger scale: electronics doesn’t like to be switched on and off. That’s a fact. That also does not mean that if you keep switching on and off your computer, then it’ll fail very soon: it means that if you take 100 computers and you switch them on and off every day, after a number of year you’ll likely to have some extra failures because of that. If you’re an end user, you likely won’t be able to see the benefit of keeping them on all the time yourself - besides the power saved. Also, this is statistics so equipment can fail anyway.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 07-22-2019 08:15 AM                     quote: Armand Daiguillon It still seems a lot of fans are still running in the projector while in stand by At most three fans are running in Standby in any given NEC projector. The card cage has to be kept cool because the CPU (top module) is running even in standby. This allows the NIC's and internal web server to continue running so you can remotely control the projector in Standby. Mark  |  IP: Logged
