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.
