Verifying Switch Operation
Before installing the switch in a rack, on a wall, or on a table or shelf, you should
power the switch and verify that the switch passes POST.
If your configuration has an RPS, connect the switch and the RPS to the same AC
power source. See the “Power Connectors” section on page 1-12, and see the
Cisco RPS documentation for more information.
Note Always put the RPS in standby mode when you are connecting devices to it and
in active mode during normal operation.
To power on the switch, connect one end of the AC power cord to the AC power
connector on the switch, and connect the other end of the power cord to an AC
power outlet.
Warning
Attach only the Cisco RPS 675 (model PWR675-AC-RPS-N1=) to the RPS
receptacle.
As the switch powers on, it begins the power-on self test (POST), a series of tests
that runs automatically to ensure that the switch functions properly. POST lasts
approximately 1 minute. When the switch begins POST, the System, RPS, Status,
Duplex, and Speed LEDs turn green. The System LED blinks green, and the other
LEDs remain solid green.
When the POST completes successfully, the System LED remains green. The RPS
LED remains green for some time and then reflects the switch operating status.
The other LEDs turn off and then reflect the switch operating status. If a switch
fails POST, the System LED turns amber.
Note POST failures are usually fatal. Call Cisco Systems if your switch does not pass
POST.
After a successful POST, disconnect the power cord from the switch. Install the
switch in a rack, on a wall, on a table, or on a shelf as described in the “Installing
the Switch” section on page 2-9.
