Installing and Maintaining BN Platforms
3-8 109352-E Rev. A
Environmental Requirements
The installation site must meet the environmental requirements listed in Table 3-7.
Setting Up the Backbone Concentrator Node
You must install your BCN in an electronic enclosure rack.
Attaching Angle Brackets
We highly recommend that you place your hardware platform on angle brackets
for added support when installing your BCN in a rack.
Before you begin, locate the hardware package that contains the brackets,
panel-mount screws, and cage nuts. You also need a tape measure and a Phillips
screwdriver.
Attach angle brackets as follows:
1. To ensure that the slots in the BCN flanges align with the holes in the
rack:
a. Measure at least 28 in. (71 cm) of free vertical space inside the rack
and mark the spot.
b. Locate the next two holes below this spot that have a 0.625-in. space
between them.

Caution: Before you set up your BCN, refer to “Space Requirements” earlier
