Chapter 2: Installation

7.Secure the tray supply cable near the rack framework using multiple cable ties to minimize the chance of the connections being disturbed by casual contact with the wiring. Use at least four cable ties separated four inches apart with the first one located within six inches of the terminal block.

This system works with a positive grounded or negative grounded

DC system.  E13

8.Ensure that the circuit breaker is in the Off position.

9.Connect the DC wires to the circuit breaker. (Refer “Power Specifications” on page 82 for power requirements.)

10.Power on the circuit breaker.

11.Verify that the PWR LED on the front of the unit is green. If the PWR LED is OFF, refer to Chapter 3, “Troubleshooting” on page 77.

The switch runs a series of self-diagnostic tests, which take a few seconds to perform. After the self tests are complete, the switch is ready for normal network operations.

Warning

This unit might have more than one power cord. To reduce the risk of electric shock, disconnect all power cords before servicing the unit.  E30

No further installation steps are required if you do not intend to change the default operating parameter settings of the switch, which are listed in the AT-S62 Management Software User’s Guide. However, if you want to manage the switch, refer to “Starting a Local Management Session” on page 73.
