Ports and Status Indicators

The MS uses EDs to inform the user of the device's status. When the device powers on, all the Internet EDs flash

twice. Additional functions are described below, from left to right.

In addition, there is a RESTORE button available on the front panel.

Insert a paper clip if a restore is required.

• A brief, momentary press: To delete a downloaded configuration and reboot.

• Press and hold for more than 10 sec: To force the unit into a full factory restore.

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

Equipment is to be used only in a restricted access location and installed/operated only by trained service

personnel.

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

MS220-48 P 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:

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=

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.

Only the RPS2300 chassis (PWR-RPS2300) and accessories are supported. For more information, see

the RPS2300 datasheet
