Installing an Avaya MCC1 Media Gateway

Check Commercial Power and Connect AC Power

Before powering up the S8700 Multi-Connect configuration, check the AC power using a
KS-20599 digital voltmeter (DVM) (or equivalent).
Set the DVM to the 250 volt range.

2 Carefully measure the voltage between the hot and neutral side of the receptacle. The
neutral wire is white, the hot wire is black.
3 Verify the meter reads 106 to 128 VAC. If not, have a qualified electrician correct the
problem.
Measure the voltage between the neutral and ground side of the receptacle. The ground

wire is green.
Verify the meter reads 0 VAC. If not, have a qualified electrician correct the problem.

Connect Fiber Optic Interconnect Cabling

Signals between the PN with the center stage switch (for convenience called PN1) and the other
PNs are carried by fiber optic cables. Lightwave transceivers provide the required fiber optic
interface.
The fiber optic cables from the center stage switch route to a Lightguide Interconnect Unit
(LIU) or fiber optic shelf.
Use multimode fiber transceivers and multimode fiber optic cables between media gateways
unless single-mode fiber is required (distance restrictions). Use metallic cables between
carriers.
!
CAUTION:
The PN with the center stage switch may contain a Class 1 LASER device if a
single-mode fiber optic cable is connected to a remote port network.
Make the required connections for the installation:
