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 MS225 series supports connecting the Cisco RPS2300 for optional power redundancy. MS225 series models support failover and reversion to main power once it has been restored. The following Cisco part numbers are supported:

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 [idle/max including PoE]

MS225-48 25 / 42 W
MS225-48LP 53 / 490 W
MS225-48FP 54 / 882 W

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


Bringing your Stack Online

The MS210 and MS225 series switches additionally support cross-model stacking, meaning an MS210 can be stacked with an MS225 and vice-versa.

MS225 switches can be connected in a physical stack using dedicated stacking ports and cables. Configuration steps and additional information about stacking can be found here.

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.

Optional Mid-Mount bracket

MS225 48 port models are designed for an optional MA-MNT-MID-1 mid-mount bracket when using 2-post racks.
