Mechanical Installation
Caution If the BPX switch is to be mounted in an enclosed cabinet, ensure that a free flow of air in
and out of the enclosure is provided. Contact Customer Service for further information.

Horizontal Positioning

BPX switch shelves are designed to be mounted to two sets of vertical mounting rails in either a Cisco
cabinet or a standard 19-inch equipment rack with unrestricted front to rear air flow. When installed in
a Cisco cabinet (see Figure 7-2), the front flanges of the BPX switch are secured to the front rails of the
Cisco cabinet. In factory installations, rear support is provided by rear mounting rails in the cabinet at
a setback of 19.86 inches. As an option, a rear set of rails located at a setback of approximately 30
inches may be used for rear support.
BPX switch shelves can also be mid-mounted to an open T-Rail type rack (see Figure 7-3) with
unrestricted front to rear air flow. To facilitate this type of installation, brackets may be fastened to the
BPX switch shelf at a 5 or 10 inch setback for supporting the front of the BPX switch shelf. Additional
rear mounting support is also recommended. Contact Customer Service for further information.
