Well, that was mildly exciting

Replaced the battery in my UPS a few minutes ago. All went well except that I managed to pull the plug on my news/dialup server (on the other UPS, which was on top of the stack and so had to be moved first). The supply doesn't seem to have noticed that it has a new battery; I'll probably have to wait for it to self-test again, unless I want to power down. Think I'll wait 'til tomorrow morning after I run the backups.
