A power surge came in! I work in a very remote location that utilizes a SCADA system. Our SCADA servers are located on site in a locked office, two redundant ones, each on their own UPS. Last week we had a issue in the breaker panel for this office that our electrician didn’t have the parts to fix. This being a critical SCADA system, our guy on shift called our help desk 700km away. The t1 guy escalated and the resulting help desk person had our 70 year old, never owned a cell phone or computer guy move the two small servers to another office and got them plugged into network ports. Within 45 minutes our SCADA system was back up and running. Hurray! However, the servers were the only thing that was moved. The UPS for both stayed behind. So the servers were plugged directly into the wall of a building with notoriously unreliable power and that is known to surge badly. And a week went by with no problems, and no one noticing the issue because the servers are still in a locked office. Today a truck hit a power pole and blew a transformer. The lights flickered and all our SCADA systems crashed. I’m sent to make sure the servers are on and I’m greeted by the wonderful smell of burned and melted capacitors. Apparently a person has been woken up and told to drive here with new servers for us, and he should be here in another 5 hours. In the meantime we’ve been running around shutting stuff down manually until we can control it again. Fun times. This should make for a wonderful end of shift meeting.

It'd be a lot weirder if the cables went out, made an immediate 90 degree turn, and then went straight back in to the unit above/below instead of that graceful curve they've got going on.

With 6" cables it works out, because a 6" cable actually only has about 4.5" of actual cable between the boots - the 1" vertical or so drop between a switchport and the patch panel port below it means that you only have 1.5" out and back in, and since cables obviously aren't going to do actual 90 degree bends (unless you force them to because you're a Besides which, the whole point of doing that (other than never having to trace cables or manage them) is to get higher density in the rack - if you have 1U blanking panels that kind of destroys the increase in density you fought so hard to achieve. Increase in density is also my pet name for our FNG.

Coming up to hour 48 on client site and this has been a total poo poo show. Server is still hosed and not working. Copying data from two different sources at the same time crashes it. Exchange isn't properly configured and not syncing with AD so email cant be setup. The SSD imaging method the boss wanted me to use doesn't work with the clients new desktops. I had to go back to the office, make a bootable USB key for a different tool, because the three USB keys we brought on site are all dead. I'm giving the shop a once over before I leave to make sure that I don't have to come back again today. Then I get to be onsite tomorrow most of the day to "resolve issues". At this rate I wouldn't be surprised if the server had to be fully rebuilt. Again. Because we had to rebuild it last week for reasons I wasn't told.

Entropic posted:You've never seen this kind of setup? I've seen this before of course but I was taught not to use patch cables that short because they couldn't be certified. Doesn't mean they won't work, but if a manufacturer can't certify a cable, it can't warrant that it meets standards.

I'd rather use uncertified cables (from a reputable supplier) than have to lose metres of slack in vertical management, almost guaranteeing to cause damage whenever a patch needs to be moved.

Entropic posted:You've never seen this kind of setup? I can't fathom why people don't at least strive for this every time they setup a rack. I do this and even go farther to have cable colors for the ports role. I tend to have to fight off other people who try and plug rack mounted servers/appliances/whatever directly into a switch and then have to swat them down with the quickness. Its device -> patch panel in the same rack -> patch panel in network rack -> switch. Its clean, its efficient, it doesn't look like total loving garbage.

I like having neat server racks because its a visual representation of how organised i am. Nobody is looking at my list of notes, completed tasks and "todo's" if i'm on top of it, but the rack by the keys (small business guys, be nice) gets seen daily.

Plus it makes me feel organized and better. We did a huge cleanup mid-last year, as best we could without being able to actually shut everything down. We really need a 24-48 hour window where we can have free reign to fix it, and we'd have it all looking amazing. But, 24/7/365 here, so short of some form of IT miracle, its as good as it will get for now.

The most important thing is never to route cables across devices. So if you have devices A, B, C you should route cables between A and C so that you can still remove B without having to disconnect anything else.

Getting outage windows to reboot servers for various issues is hard enough, let alone trying to schedule one for "cleanup". We'll get it done eventually, just not anytime soon. Bigger fish to fry as well, its ~mostly~ cleaned up now, we just need to make it easier to trace.

I've been lurking this thread and the previous one, so I thought I would share a story that happened to me recently: User: Hey, I'm trying to watch this webinar and it says I don't meet system requirements. Me: Remotes on computer and looks at system requirements. Compatible OS's are MAC OS X, Chrome OS, Linux, and . . . Windows Vista or earlier. Me: Well, those are some . . . interesting requirements. Oh look, it will also work in Chrome. *installs Chrome, goes to link. Site runs compatibility check and is fine with Windows 7.* I guess it's because Windows 7 is Vista: Working Version which is why it's fine with it, but what the hell kind of janky software wants Vista or earlier in the YOOL 2018?

Our only window for disruptive repairs was like, 30 minutes before they opened and the rack was such a shitshow I couldn't redo the wiring and test the network in one go. When I left that employer, the client had a fully configured but untested Cisco switch in their rack, with nothing plugged into it and everything still running over an old/failing HP switch.

We've got some version of PeopleSoft that checks against a whitelist of OS versions, and tells you your OS isn't supported if it isn't on the list. Unfortunately that list doesn't get updated, so people on Win10 or High Sierra get told their OS is out of date. Still works perfectly fine after you log in though.
