Switch Installation
Connecting to Power
Attaching the Power Connectors to the Switch
To attach the power connectors to the front panel of the switch, follow these steps:
1. Insert one power connector into the DC-A receptacle on the switch front panel, and the other into the DC-B
receptacle. See Figure 8 on page 17.
Warning: Installation of the equipment must comply with local and national electrical codes. Statement 1074
2. Use a ratcheting torque flathead screwdriver to tighten the captive screws on the sides of the power connectors to
1.6 in/lbs.
Caution: Do not exceed 1.6 In/lbs.
When you are testing the switch, one power source is sufficient. If you are installing the switch and are using a second
power source, repeat this procedure for the second power connector (DC-B), which installs just below the primary power
connector (DC-A).
When you are installing the switch, secure the wires coming from the power connector so that they cannot be disturbed
by casual contact. For example, use tie wraps to secure the wires to the rack.
Applying Power to the Power Converter
Move the circuit breaker for the AC outlet or the DC control circuit to the on position.
The LED on the power converter front panel is green when the unit is operating normally. The LED is off when the unit is
not powered or is not operating normally. After the power is connected, the switch automatically begins the power-on
self- test (POST), a series of tests that verifies that the switch functions properly.
