Shelf assemblies have equipment mounts, interconnected wiring, and accessory boxes. Most equipment rack shelves are cooled with air. Air is blown through or drawn through the equipment racks.
There is a drip shield over the racks to protect the equipment from moisture condensation.
The airplane has an E6 equipment rack (not shown) in the aft cargo compartment on the right side, aft of the cargo door. The rack does not have cooling air. The equipment on this rack is passively cooled.

737 GENERAL -- EE COMPARTMENT DOOR OPERATION Operation
You manually operate an external access door to the electronic equipment (EE) compartment. You open and close the door from outside the airplane.
Open Door
The handle on the door fairs in a recess. A push-button trigger releases the handle, and it comes out of fair by spring force.
Turn the handle counterclockwise to disengage the latch pins. When the latch pins are free you can push the door upward and slightly to the right to the first detent. Then push the door to the right to the fully open detent.
When the door is fully open, the roller tracks can be folded to improve access to the equipment racks. A spring catch on the end of each roller track holds the track in the folded or unfolded position.
Close Door
Before you close the door, release the spring catch and extend the roller tracks. Make sure the door frame area is clear.
Pull the door out of the fully open detent and then restrain it as gravity causes it to slide down the tracks. When the door reaches the lower detent you can release it.
737-600/700/800/900 TRAINING MANUAL

Pull the handle to the left and the door will come out of the partially open detent. Then it slides down into the door frame.
Turn the handle clockwise to latch the door. Then push the door handle back into its recess.
