The head sysadmin was gone and there was an incident that required rebooting or power-cycling the critical Sun 4/390 server that was in a locked machine room, so people were asking me what to do, but I hadn't yet been allowed to touch that server.
This machine handled email, special Internet gateway, Usenet, Sun YP maps, license servers, most of the critical NFS volumes (home directories, tools, SCM of our code), and maybe some weird thing for the non-engineering people who only had Windows boxes.
At the time, I thought of power-cycling as risky (for one thing, we had enough SPARCstations with Quantum 105 drives, that a rare power outage meant that we'd usually lose a workstation, though the 4/390 used huge IPI drives). And I think I didn't have that root password, and maybe not even the door keypad code that the console was behind.
So I mostly just speed-walked around the building, as if with purpose, while trying to figure out who I could contact, to get access and tell me what the safe procedure was to reboot/cycle the big loud machine that everything depended on.
