Classical Test Compliant Rack-Mountable Ethernet Switch Box

Disclosed is a device to mount an off-the-shelf ethernet switch box or similar system in a 19" standard rack. The device incorporates features for tool-less mounting, cooling, ease of manufacturing, servicing, safety requirements, and power interconnect. There are multiple problems that this invention solves:

Mounting in a rack, an ethernet switch box that was not designed specifically to be


1.


2.

mounted in a rack.

The airflow pattern for cooling the ethernet switch box is side to side, which is not

compatible with standard IBM* rack mounting.

The brackets included with the switch box for rack mounting, mount only to the rack


3.

EIA rails and, therefore, cantilever the box out from these rails. This leaves the rear of the box unsupported; not a good practice in a shipping environment.

The power connector is located on the back of the box, making it difficult to access

from either the front of an ethernet system or the opposite side of a rack. Since the ethernet switch boxes are mounted at the rear of the rack, a person would have to reach in approximately two feet in order to plug in the power cord. This also causes cable management problems. The other option would be to reach behind the ethernet box while standing at the rear of the system. Due to the fact that there are other components in the rack above and below the ethernet boxes, this is impossible without removing the assembly from the rack. Plugging the power cords into the ethernet boxes either of these two ways is a safety concern.

Safety is requiring a "quick disconnect" in case of an emergency. This is not

possible with the off-the-shelf design.

     The only known solution is to leave the ethernet switch box outside of the rack on a table nearby and cable to the rack. This is not efficient nor is it desired. The vendor does provide simple bracketry for mounting the switch box in a rack, but this bracketry does not contain power cable management nor airflow management. These brackets do not have a value add that IBM requires in this application.

     This disclosure addresses all of the above deficiencies in the current off-the-shelf design. The new mounting method incorporates mounting rails and brackets that give support along the full length...
