Ports and Status Indicators
The MS uses LEDs to inform the user of the device's status. When the device powers on, all the Internet LEDs flash
twice. Additional functions are described below, from left to right.

Equipment is to be used only in a restricted access location and installed/operated only by trained service
personnel.
RPS2300 Redundant Power Supply (Optional)
The MS220-24 series supports connecting the Cisco RPS2300 for optional power redundancy. MS220-24 series models
support failover and reversion to main power once it has been restored. The following Cisco part numbers are
supported:
Part number Description
PWR-RPS2300 RPS Chassis
C3K-PWR-750WAC 750W RPS Power supply (see recommendations)
C3K-PWR-1150WAC 1150W RPS Power supply (see recommendations)
CAB-RPS2300-E= RPS 22-pin cable

RPS power supply matrix
Switch Model Full power load, [switch only / including PoE]
MS220-24 18 W / not applicable
MS220-24P 77 W / 447W
MS220-48 51 W / not applicable
MS220-48LP 135 W / 505 W
MS220-48FP 163 W / 903 W
Example configurations
Example 1: "I have 3 x MS220-24 and 3 x MS220-48 switches connected to my RPS2300"
3 x 18W = 54W
3 x 51W = 153W
54W + 153W = 207W total power draw
Recommended hardware:
1 x PWR-RPS2300
1 x C3K-PWR-750WAC (750W) OR 2 x C3K-PWR-750WAC (750W) for redundancy
6 x CAB-RPS2300-E=
Example 2: I have 6 x MS220-24P switches connected to my RPS2300. I also intend to use the full PoE budget of
370W on each switch and want to back it up in case of a failure.
6W x 447W = 2683W total power draw
Recommended hardware:
5
1 x PWR-RPS2300
2 x C3K-PWR-1150WAC (2300W)
6 x CAB-RPS2300-E=
Example 3: I have 3 x MS220-48 and 3 x MS220-48LP connected to RPS2300. I also intend to use the full PoE budget
on each of the PoE switches but I do not need to back it up in case of a failure.
3 x 51 = 153W
3 x 135 = 405W
153W + 405W = 558W total power draw
Recommended hardware:
1 x PWR-RPS2300
1 x C3K-PWR-750WAC (750W) OR 2 x C3K-PWR-750WAC (750W) for redundancy
6 x CAB-RPS2300-E=
Only the RPS2300 chassis (PWR-RPS2300) and accessories are supported. For more information, see
the RPS2300 datasheet
Mounting hardware
The mounting hardware includes a rack mount kit for standard 1U racks. When installing the device, make sure that
there is sufficient space between the rear of the rack and other obstacles to ensure adequate airflow.
