Chapter 2 Switch Installation

Planning the Stack

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 1-25, and see the Cisco RPS documentation for more information.

Note Always set 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 Appendix C, “Connecting to DC Power,” for complete instructions.

Warning Attach only the Cisco RPS model to the RPS receptacle:

As the switch powers on, it begins the 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 2-11.
