Powering the Switch and Connecting Devices
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 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 4, “Troubleshooting,” to determine a course of action.
Connecting a Cisco RPS
Use the cable supplied with the RPS to connect to the switch rear panel. Connect
the switch and the RPS to the same AC power source. Always put the RPS in
standby mode when you connect devices to it and in active mode during normal
operation.
Note Make sure to connect the switch and the RPS to the same AC power source.
You can connect the Cisco RPS 300 (model PWR300-AC-RPS-N1) to these
switch models:
• Catalyst 3550-12T, 3550-12G, 3550-24, 3550-FX, or 3550-48 switch. (The
Cisco RPS 300 does not support the Catalyst 3550-24-DC or 3550-24PWR
switch.)
Warning Attach only the Cisco RPS (model PWR300-AC-RPS-N1) to the RPS receptacle.
