7.2. Rack Mounting the BSDU
The BSDU is designed for mounting in a standard 19-inch (48.3 cm) equipment rack
or telco rack with 1 rack unit (1-U) of vertical rack space. The sides of the BSDU
chassis provide integrated front-rail mounting brackets. Therefore, all that is
required for mounting the BSDU is to attach the BSDU front-rail mounting brackets
to the rack. The mounting brackets are secured to the rack's mounting rails using the
supplied four M5 mounting screws and plastic cup washers.
To rack-mount the BSDU:
1. Determine which rack rail holes—left and right side—will be used for attaching
the chassis.
2. Insert four nuts into the rack's rail holes you designated in Step 1. These nuts are
housed in Tinnerman clips, which allow you to fasten them into the rail holes.
To insert the Tinnerman clips, hold the clips, squeeze them, and then insert them
into the rail hole.
3. Carefully insert the BSDU into the rack, aligning the BSDU’s mounting bracket
holes with the rack rail holes.
4. Insert the M5-mounting screws, with plastic washers, into the BSDU mounting
bracket holes, on each side, as shown in Figure 7-10. In this way, the chassis is
supported until you tighten the chassis screws.
5. Tighten the M5 mounting screws to fasten the chassis to the cabinet.
