Powering the Switch and Connecting Devices

These sections describe powering the switch, connecting an RPS, connecting cables, and inserting GBICs.

Powering the Switch

Use the supplied AC power cord to connect the AC power socket on the switch rear panel to an AC power outlet.

When the switch powers on, it automatically begins the power-on self-test (POST), a series of tests that verifies that the switch functions properly. When POST completes, the system LED is green. If the switch fails POST, the system LED is amber, and the port LED associated with the particular test is amber.

If POST fails, see Chapter 3, “Troubleshooting,” to determine a course of action.
