Step 3: Connect Ethernet
The C424G ONU supports four, 1 Gigabit (10/100/1000Base-T) connections (1 to 4).
If Ethernet cables are not available, use the following procedure and table to create the Ethernet cables:
1. Trim the insulation for the subscriber Ethernet cable.
2. Using a CAT 6 cable, connect the wires per the following table using an RJ-45 Crimper.
3. Refer to Figure 1 and insert the CAT 6 rated cable in the appropriate Ethernet port.
Step 4: Connect Power
Refer to Figure 1 and plug the 12 VDC Power Adapter (supplied with the unit) into the
12V DC2.5A
connection on the rear of the chassis.
Connect the AC plug to a standard 120 VAC outlet.
Step 5: Connect Uninterrupted Power Source (UPS)
The step is optional. The C424G ONU can typically use an un-interruptible power supply (UPS) if desired. Power is supplied to the
C424G ONU by a local power source with battery backup that utilizes the AC power at the customer premises. The UPS powers the
C424G ONU supplying continuous 12 VDC. Refer to the installation material that is provided with the UPS.
To connect UPS, refer to
Figure 1 and connect a UPS cable from the source to the UPS port on the rear of the unit.
