Description

3.4.1Function

Front and rear door are kept closed with two electromagnets. The door will be pushed open smoothly by a gas pressure spring if power to the electromagnets fails.

If the doors are opened, the thermal load can escape into the room, preventing the servers from over- heating.

The inflow of air with water droplets can also be prevented (Door opening due to humidity alarm). When the rear door is opened, the fans shut down automatically.
