4.Connect the A feed 48V return wire to the screw terminal labelled “A +” on the rear panel of the switch, and use a flat screwdriver to tighten the screw to a torque of 0.5 to 0.8Nm (4.4 to 7.1lbf in). Ensure no wire strands protrude from the terminal. Note that the DC return input terminal must be connected as Isolated DC return (DC-I).

5.Use the same procedure to connect an additional power source, if required, to the terminals labelled B.

6.Secure the tray cable near the rack framework using multiple cable ties to minimize the chance of the connections being disturbed by casual contact with wiring. Use at least four cable ties separated 10cm (4inches) apart with the first one located within 15cm (6inches) of the terminal block.

7.Energise the DC power source to the switch.

The Fault LED should light for approximately 3 seconds as the switch runs internal tests. If the LED remains lit, refer to the Rapier Switch Hardware Reference for troubleshooting information.

8.Check that the Power LED on the front panel lights green.

If the LED fails to light, refer to the Rapier Switch Hardware Reference for troubleshooting information.
