Chapter 2 - Hardware Installation

8.Place the MCU in a 23” rack and while supporting it, screw the mounting brackets to the rack securing it with bolts and self-locking nuts.

When the unit is installed on a rack, the rack must be properly grounded to the central office ground. The rack must be grounded with two-hole compression- type connectors using copper conductors (tinned or untinned). Wire, bus bar or braided strap connectors are acceptable.

Mounting the MGC-100 on a 19” Rack

The MGC-100 can be mounted in a 19” rack using the mounting kit (P/N- KIT2026A). It is highly recommended that the 19” rack be located in an air- conditioned room.

Figure 2-3 shows how to mount the MGC-100 on the 19” rack.
