2.5.1
Grounding The Stations
Remember, if spare conductors exist in the cables that run between the stations and the 66M-xx
connector blocks, it is good practice to connect them to earth ground. Doing this may help
prevent them from introducing radio frequency and/or AC interference into the system. Also
remember that it is good practice to disconnect any unused station jacks from the connector
block and ground that wiring to earth ground as well.
Remove insulation and twist together all spare wires at the wall outlet. Ground the wires at the
66M-xx to the common equipment cabinet ground lug.
2.5.2
Relocating The Stations
The Comdial proprietary telephones identify themselves to the system when you install them.
The system assigns an extension number and all other programmable attributes to station ports as
a default that you can reprogram as needed. Plus, you can use programming action to reassign
attributes of one station port to a different station port if you wish. This station relocation feature
allows you to do adds, moves, and changes without relocating the station wiring. Refer to the
automatic station relocation programming procedure and the station-to-station programming
procedure found in Chapter 3.
NOTE: The system will not allow you to relocate the station 10 to station port 10 assignment.
2.5.3
Installing The Cable Clips
Each cabinet-mounted 50-pin male connector is equipped with a retaining clip. This clip is
designed to secure the mated connection once it is made. The clip does this by snapping into a
slot on the cable-mounted connector when it is pressed together with the cabinet-mounted
connector. This retaining clip must be pulled back slightly to unsnap it before the connectors can
be separated.
