If the door sensors die:

• On Mussel, as root:

/etc/init.d/uccdoors stop
/etc/init.d/latd restart
/etc/init.d/uccdoors start

• On Madako, as root:

moprc -i eth0.2 janus
<enter password>
<enter username (UCC)>
set priv
<enter privilege password>
init del 0

Not all these steps may be necessary - often, resetting the DECterm (second item above) will do the trick.

Some tricks and lessons learned

• The door solenoid requires a fair bit of power, the huge power supply in the machine room is huge because it needs to be. Don't try and substitute it with a wall wart.
• Similarly, the door solenoid struggles for power when you try and power it with only 2 of the 4 wires. Instead, connect 2 wires to each terminal.
• The modem takes 12V, so does the solenoid - don't try giving it 9V, it doesn't like it
• To test if you have connectivity to the modem:
  • From mussel:

  • llogin door -w-

  • Enter the password
  • From here you can send characters to the modem (they won't come up on the screen though)
  • Watch the lights on the front of the modem, one of them should turn on and flicker when you're sending data
  • To manually open the door over serial type ATH1F (case sensitive) and hit enter
