Connection
An RPS150 power and communication cable is often used as a common power cable and is not hot swappable.
- Power-on: Connect the RPS150 power and communication cable to the router and RPS power supply, and then power on the router and RPS150 power supply.
- Power-off: Power off the router and RPS150 power supply, and then remove the RPS150 power and communication cable.
An RPS150 power and communication cable is connected as follows:
- One end (20 pins) is connected to the RPS connector on a router.
- The other end (20 pins) is connected to an RPS150 power supply.
