Installing the System in a Distribution Rack

You can mount the CoreBuilder 9400 system into a

48.26mm (19-in.) distribution rack. This section describes how to prepare the system and distribution rack for installation and how to mount the system in the rack.

Install your distribution rack near an easily accessible power outlet. You can power down the system only by removing the power cord from the power source.

To prepare the system and distribution rack for installing the CoreBuilder 9400 system:

1See Appendix C for distribution rack requirements.

2Attach one of the L-shaped mounting brackets to one side of the CoreBuilder 9400 using the 8-32 x 1/2 Phillips flat-head screws. Attach the other bracket to the other side. See Figure 4.

You are now ready to cable the system. For cabling instructions, see Chapter 3.
