+1, though I'm honestly not a networking person. I'd maybe show up to help
document things but couldn't give good input.

It is, though when I got here earlier this evening it was dead. To fix it, I:
1. Unplugged all the POE lines
2. Wired together the lan ports on the two POE injectors
3. Plugged the monkeybrains line into a POE port
4. Plugged the noisebridge wifi line into the other POE port
As it stands, the current setup is: Monkeybrains -> POE Injector -> POE
Injector -> Noisebridge wifi. Ugly, but at least I've got wifi that can send
mail to rack at .
Bikeshed has been doing nothing at all and was last seen with an error light,
so I've got it on a workbench to try and coax some serial data out of it and
see why it isn't working. I also can't access minotaur, so I'm kinda grasping
around in the dark.
Should Bikeshed have some CF card to boot off of? Its socket is empty :(
Related: I hear that we might be getting a new switch sometime soon? Would it
have POE so that we wouldn't have two loose POE injectors just sitting there,
waiting to be messed with? I'm in favor of buying a standalone rackmount POE
injector as well if a non-POE switch has already been acquired.
