Power Connection
Make sure the power switch on the front panel is
OFF
. Attach a ground wire to ground lug on the back
panel. The chassis must be grounded using the ground lug to reduce the risk of damage from lightning.
The system is powered by 48VDC and may accept 12 or 24VDC and/or 115/240VAC with the provided
adapter for the specific order. Both inputs may be used at the same time, providing redundant power for
the unit. Once all connections are checked and power is applied, turn the unit
ON
using the power switch
on the front panel.
Note:
The DC power terminals are polarity sensitive. Observe the and
terminals on the DC input terminal.
Optical Ports
The optical ports may be equipped with ST, SC or FC fiber connectors. A fiber pair is required for
operation with dual fiber models, TX is the signal output side and RX is the signal input side. Bi-directional
single fiber models combine input and output, and require only a single fiber.
DIP Switch
The DIP switches are for factory settings and testings and should not be changed by the end user. For
proper operation set all the DIP switches must be set to the
OFF
, or
UP
position.
Analog Phone Ports
The POTS ports use the center 2 pins of RJ-45 connectors. Use the included adapter connectors to
attach RJ-11 connectors to the POTS Mux.
Note:
All ports are included on each unit, but only the ports that are installed on your unit are active, the
unused ports are inactive. Refer to the product label to see the POTS channel capacity on your unit.
