Just recently, I discovered that IBM decided to quietly switch their UPS vendor from APC to Eaton (Powerware). We needed to replace a dead IBM UPS 3000 XHV (SmartUPS-3000) and so I ordered a new IBM UPS, the UPS 3000 HV (Eaton 5125). Upon receiving the UPS, I noticed that the battery and power module were rather different. So I boot up the UPS and start configuring the web management card and it hits me… this isn’t an APC UPS, it’s an Eaton! ARG! Why?!? WHY?!? :'(
Every now and then it’s a good idea to check your UPS batteries, right? Sure, we all know that. But who really does it? In well run environments UPSes are monitored, internally and/or externally but in a small machine room with only a couple racks, the individual UPS systems may not be monitored. These machine rooms (closets?) might also not be frequented by people very often or may not even get a visit, ever unless something goes wrong.
I recently started paying more attention to the OpenGear CM4116 remote console server that was installed at my work before I arrived. Ever since I arrived, I thought of it as more of a pain than a useful tool. This was mostly because it was configured to provide only serial console access to servers and storage devices through an SSH tunnel.
