2–3Installing the Chassis and Power Supply Module
Installing the Chassis in a Rack
The DEChub 900 MultiSwitch chassis can be installed either in a 19-inch equipment
rack or on a wall using the mounting bracket and hanger.
Rack mount brackets and mounting hardware, for installing the chassis into a stan-
dard RETMA 19-inch equipment rack, are supplied with the DEChub 900 Multi-
Switch chassis (see Figure 2–1).
You can use the cable ring bracket supplied with your chassis to manage the cabling
from the network modules (see Figure 2–2). This bracket accommodates eight cable
rings. You can snap the cable rings into the holes in the bracket and then route cables
through the rings.
Perform the following four steps to install the chassis in the equipment rack:
1. Locate the rack mount brackets and the ten #6–32 machine screws that are
supplied with the chassis.
2. Attach the rack mount brackets, using the #6–32 screws, to the back of the
chassis.
3. Install the chassis in the equipment rack using the eight #10–32 machine
screws and U-nuts (if necessary).
4. Install the ac power cord into the ac connector at the bottom of the chassis.
5. Some rack mount bracket assemblies have a punchout on the right rack
mount bracket, which is used to attach a cable tie. If your assembly has a
punchout, secure the ac power cord to the punchout using a cable tie.
