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, 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.
Note POST failures are usually fatal. Call Cisco Systems if your switch does not pass
POST.
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 “Installing
the Switch” section on page 2-16.
