3 x 8 Module

Option Module
Standard MOH/BGM Module
3 x 8 Module
The 3 x 8 module requires one 25-pair amphenol type (male) ended station cable to
extend the interface ports to the MDF. The station cable is plugged into the female
amphenol connector at the base (orientation assumes a properly mounted KSU) of the
3x8 module.
It is very important that the KSU be correctly mounted to allow proper
power supply heat dissipation.
System power should be OFF before plugging in the station cable or while working on the
station punch-down block. (Although each port is over-current protected, unnecessary
shorting should be avoided).
