Connecting the Cisco RPS
This chapter provides instructions on connecting your external device to the
Cisco RPS. The chapter is divided into the following major sections:
• Power Considerations, page 4-1
• Connecting Hubs, page 4-2
• Connecting Switches, page 4-6
• Connecting Routers and the Cisco MC3810 Concentrator, page 4-13
Power Considerations
Before connecting to external devices, read the power warnings below. We
recommend that you disconnect all power before beginning.
Note If you want to connect an additional external device to a Cisco RPS that is already
powered up, you can do so without interrupting power to the Cisco RPS or any
other connected external devices. Be sure to connect your cable to the Cisco RPS
first and then to the external device. However, in a redundant-with-reboot
configuration, to ensure proper operation, you must power up the switch or hub
before powering up the Cisco RPS. Therefore, always connect the switch to AC
power before you connect it to the Cisco RPS. Failure to follow the proper
power-up sequence can result in incorrect LED displays.
