Powering On the Switch and Running 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
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.
To power on a DC switch, see
Attach only the Cisco RPS (model PWR675-AC-RPS-N1) to the RPS receptacle. Statement 100C
Warning
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, the RPS, the Master, the Status, the Duplex, the Speed, and
the Stack LEDs turn green. (On the PoE switches, the PoE LED also turns green as POST begins.) The
System LED flashes green, and the other LEDs remain continuous green.
When POST completes successfully, the System LED remains green. The RPS LED remains green for
some time and then returns to its operating status. The other LEDs turn off and return to their operating
status. When POST fails, the System LED turns amber.
POST failures are usually fatal. Call Cisco Systems if your switch does not pass POST.
Note
Powering Off the Switch
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
