Server Cabinet Door Replacement

Are you trying to cool servers in a glass enclosed server cabinet? Here are some do-it-yourself options.

No matter hard you try, it is impossible to push air through a solid glass door. All of your rack mounted servers were designed to draw cold air from the front and exhaust the warm air out the rear. It is imperative that the servers be able to draw cold air without obstruction. How is it possible to provide adequate air-flow to critical servers when a glass door prevents air penetration?

If the existing door is like a picture frame where the glass is an insert and the door has metal all around the glass, then the glass panels can easily be replaced. Measure the glass panel, have a mesh panel cut to size and powder coated, pop out the glass, and insert the panel. Mesh panels should not affect the integrity of the door structure or the security of the cabinet.

Why mesh instead of simply removing the door? The obvious answer for some customers is to simply remove their existing doors.  This is not a great solution in that it does nothing for security and it does nothing for EMI (Electro-Magnetic Interference).  Without getting too geeky, the point of keeping computers wrapped in a metal box is that it shields the insides from radio interference in the air. Think of the metal mesh inside the glass window on your microwave.  That mesh is acting as a Faraday Cage to contain EMI generated by the microwave tube.  Bottom line, the mesh doors protect the equipment in the rack from EMI.

If the glass is not surrounded by a metal frame on all four sides it means that the glass is part of the structure of the door and can not be replaced. The doors have to be replaced. Your best bet is to contact the manufacture of the cabinet and see if they are making mesh doors for these older cabinets. Order replacement doors, change the hardware over, and hang the door.

If the rear doors are solid steel panels, you can have them louvered. Just like the hoods and trunk lids in the 40's and 50's, have louvers cut in the doors. It is very inexpensive and a simple process. Take the door to a custom body shop and have them stamp louvers in the doors. The cost for louvers is about $30 per door.
