All EX4600 switches, except the EX4600-40F-S switch, are supplied with two factory-installed power supplies and power
cords. Order separate power cords for the EX4600-40F-S.
Connecting EX4600 to AC power
To connect power to an AC-powered switch:
1. Connect each power supply to a dedicated power source outlet.
2. If the AC power source outlet has a power switch, set it to the OFF (0) position.
3. Insert the coupler end of the power cord into the AC power cord inlet on the AC power supply faceplate.
4. Push the power cord retainer onto the power cord.
5. Insert the power cord plug into the power source outlet.
6. If the AC power source outlet has a power switch, set it to the ON (|) position.
7. Verify that the AC and the DC LEDs are lit green and are on steadily.
Connecting EX4600 to DC power
To connect power to a DC-powered switch:
1. Ensure a licensed electrician has attached a cable lug to the grounding and power cables you supply.
2. Verify that the DC power cables are correctly labeled before connecting the power supply. The DC power supply has
four terminals labeled V+, V+, V–, and V–; the power source cables are labeled positive (+) and negative (–). The V+
terminals are often referred to as +RTN, and V– terminals are referred to as –48 V.
