Alarm Handling

Cluster Room Alarm Handling

The cluster room (822) gets hot when the air-conditioning stops working. This normally happens because the chilled water supply gets cut off. There are two high temperature alarms in the room:

1. The alarm on the air-conditioning unit (long continuous whine)
2. The alarm for the room (red flashing light + sound)

If one of the alarms sounds please do the following:

1. Mute the alarm
2. Ring someone who is able to shut down the servers: Roy. If they cannot be contacted or if they are unable to shut down the servers remotely, then enter the room and press for 1 sec the power buttons on each of the computers in the racks. This should trigger an automatic shutdown within. If some machines are still powered on after 5 mins, then hold down the power buttons on those machines until they turn off (usually about 5-10 sec).
3. If you cannot get access to the room, call security on 51234.

In the event that there is no-one to turn off the machines, the power to the room will automatically be cut off if it gets too hot (>35 ºC)
