Please observe these simple rules when going into the cluster room:
- THE DOOR OF THE CLUSTER ROOM HAS TO REMAIN LOCKED AT ALL TIMES
Always lock the door. If you are the last one in the lab, check
the door before leaving. If you changed the water tank, lock the
door afterwards. I found the door open most of the time during
the last weeks.
- NEVER LEAVE LIGHT OR THIN OBJECTS (F)LYING AROUND
Light objects will be sucked in by the airconditioner or, even
worse, by the computing nodes. This will overheat and eventually
kill the nodes. Be careful if you take sheets of paper, plastic
bags or anything of the like into the room.
Of course, the usual rules (switch of light and monitors etc…) apply as well.
Please make sure that you remember these rules whenever going into the cluster room.
