If you are installing additional units, you can install a second unit on the shelf beside the first unit.
You can install another unit on top of each of the first two units. Nortel recommends a maximum
of four units per rackmount shelf.
Select your installation option:
• “To install the BCM50 unit on the rackmount shelf”
• “To install a BCM50 unit on top of another unit” on page 83
To install the BCM50 unit on the rackmount shelf
1 Place the BCM50 unit on the rack so that the feet of the unit are in the depressions in the shelf.
2 Move the unit forward until the feet touch the front side of the depressions.
3 Slide the unit back until the feet click in place on the slots in the depressions (see Figure 30 ).
4 If you want to further secure the unit, use four of the self-tapping screws for plastic supplied
with the rackmount kit to attach the unit to the rackmount shelf. Make sure the screw holes in
the unit are aligned with the holes in the rackmount shelf. Then drive the four screws through
the holes in the bottom of the shelf and into the screw holes in the bottom of the unit.

Continue with the next step, “To install the power supply on the rackmount shelf” on page 83 .

Caution: Use only the screws supplied with the rackmount kit (NT9T6325). Do not
replace the screws. Other screws can damage the unit.
