For the switch with the broken fan Ian hacked a replacement which is
strapped to the outside of the case.
I ordered some higher-quality (ball-bearring) replacements.
They are Delta FFB0412SHN-BF00 and I got three for $8 shipped so we
can swap out others as they fail.
For future reference if you need to order more they are pretty
expensive from digi-key, but if you just search for FFB0412SHN on ebay
and look for a three-pin model you will probably be good, though
there's a chance you'll end up getting one where the third pin is a
"locked rotor sensor" rather than a tachometer but those are pretty
non-standard so it's unlikely.

The gateway has been replaced with a desktop computer
sitting on its
side in the rack on top of the multi-hd storage server. Note that this
is super janky since the two PCI network cards can't be mounted
properly in the somewhat-smaller-than-standard case.
We added two network cards and were planning to use the built-in card
as well, but currently the built-in card is not used and the private
network is down. There are two reasons:
* The switch used for the private network had one of its fans die and
I turned it off until we can replace the fan so it won't overheat
* The built-in network card appears to need firmware which I'm not
going to bother with until the fan on the private network switch is
replaced
Also, we might get a new server rather than using this old desktop machine.
The new computer is using the old harddrive. I changed the following
files due to the different names of the network interfaces:
/etc/network/interfaces
/etc/default/isc-dhcp-server
/etc/iptables/rules.v4
/etc/iptables/rules.v6
You can find backups of the files from before my changes at the same
paths with .old added (for the parent dir for /etc/iptables)
