BCM50 Installation and Maintenance Guide
Use the following procedures to install a BCM50 unit in a rack:
• “To install the rackmount shelf in an equipment rack”
• “To install the BCM50 unit on the rackmount shelf”
• “To install the power supply on the rackmount shelf” on page 83
To install the rackmount shelf in an equipment rack
1 Determine the location in the rack where you want to install the BCM50 unit.
2 Position the rackmount shelf in the rack.
3 Align the holes in the rackmount shelf with the holes in the equipment rack rails.
4 Fasten the rackmount shelf to the rack using the four rack screws (supplied with the rackmount
kit). See Figure 29.
5 Continue with the next step, “Installing the BCM50 unit on the rackmount shelf”.
Figure 29 Fasten the rackmount shelf to an equipment rack
Installing the BCM50 unit on the rackmount shelf
The rackmount shelf has slots molded into its surface that allow you to attach the BCM50 units to
the shelf. By attaching the BCM50 units to these slots, you can prevent them from accidently being
knocked off the rackmount shelf.
Caution: To keep the BCM50 system operating at the optimal internal temperature, keep
the top, sides, and rear clear of obstructions and away from the exhaust of other equipment.
Do not place any objects, except other BCM50 units, on top of the main unit.
