Step 2: Connect POTS (PHONE)
If POTS cables are not available, use
procedure to create the POTS cables:
1. Trim the insulation for the subscriber POTS cables.
2. Refer to the
Figure 3
and connect the twisted-pair Tip (green)
and Ring (Red) to the RJ-11 connector using an RJ-11 crimper.
3. Insert the RJ-11 connector in the appropriate PHONE 1 or
PHONE 2 jack.

Step 3: Connect Ethernet
The 424RG3 ONT supports four 1 Gigabit (10/100/1000Base-T)
connections (GE 1 to GE 4).
If Ethernet cables are not available, use the following procedure and
table to create the Ethernet cables:
NOTE
The Ethernet cables should be CAT 6 rated.
1. Trim the insulation for the subscriber Ethernet cable.
2. Connect the wires per the following table using an RJ-45
Crimper.

Step 4: Connect Power
Plug the supplied 12 VDC Power Adapter into the
the rear of the chassis. Connect the AC plug to a standard 120 or 230
VAC outlet.

Step 5: Connect UPS (optional)
NOTICE
DO NOT connect the Power Adapter and an UPS at the same time as
this will cause damage to the 424RG3 ONT. The ONT can be powered
by either power source, but not both simultaneously.
The 424RG3 ONT can typically use an un-interruptible power supply
(UPS) if desired. Power is supplied to the 424RG3 ONT by a local
power source with battery backup that utilizes the AC power at the
customer premises. The UPS powers the 424RG3 ONT and functions
as a battery backup unit (BBU) supplying continuous 12 VDC. Refer
to the installation material that is provided with the UPS when
installing the BBU.
UPS Connector
Connect the UPS to the 8-pin MOLEX connector labeled "UPS"
located on the rear of the SFU ONT chassis.

The UPS Power/Alarm Connections Table below defines each pin on
the connector.
NOTE
ADTRAN offers a UPS Cable assembly (P/N 1287402G1) for this
connector.
