Cisco RPS-2300支持的设备如下：
● Cisco Catalyst 3750-E Series Switches
● Cisco Catalyst 3750 Series Switches
● Cisco Catalyst 3560-E Series Switches
● Cisco Catalyst 3560 Series Switches
● Cisco Catalyst 3550 Series Switches
● Cisco Catalyst 2960-S Series Switches
● Cisco Catalyst 2960 Series Switches
● Cisco Catalyst 2950 Series Switches
● Cisco Catalyst Express 500 Series Switches (select PoE models only)
● Cisco 3825 Integrated Services Routers
● Cisco 2851 Integrated Services Routers
● Cisco 2821 Integrated Services Routers
● Cisco 2811 Integrated Services Routers
RPS-2300有两种电源模块：750W和1150W。如果你提供的是750W电源模块，那么Catalyst 3750-E或3560-E不被支持。
RPS-2300的输出端口可以接6台设备，但是如果你只有一个电源模块的话，只允许其中一台设备掉点后自动切换到RPS-2300供电，如果这时另外一台设备掉电，那么RPS-2300不会给这台设备供电。
如果要通过CLI方式管理RPS-2300直流输出端口的active或standby模式，那么必须要有至少一个直流输出端口接到Catalyst 3750-E或3560-E，然后通过Catalyst 3750-E或3560-E来管理：
Switch# power rps port mode standby
或者：Switch# power rps port mode active
