Cabling Procedure for MVPFXS-8/16/24
Prerequisites: To complete the MultiVOIP cabling procedure, you must have:
• One RJ-21 Cable. That cable must have a male end to fit the MultiVOIP.
The other end must fit your telephony equipment.
• Two common network cables (RJ45-to-RJ45).
Cabling entails connecting:
- the MultiVOIP to ground ,
- the MultiVOIP to power,
- the MultiVOIP to your LAN/WAN network,
- the control computer to your LAN/WAN network,
- the MultiVOIP to your telephone equipment, and
- connecting, optionally, the MultiVOIP Console port to the control computer’s serial port (needed
for initial setup only if your system cannot use the voip’s default IP address).
1. Ground Connection. Ensure that the unit is properly connected to an earth ground.
To do this, connect a grounding wire between the chassis grounding screw (see Figure 3-5) and a metallic
object that will provide an electrical ground. In some cases, mounting racks will can serve as an adequate
earth ground.
