Open Frame 750W power supply for CRS354-48P-4S+2Q+RM

MikroTik G1270 is the 750W Open Frame replacement power supply for the CRS354-48P-4S+2Q+RM switch, designed to maintain the switch's full PoE power budget when replacing a faulty unit or restoring power redundancy. It is deployed by network administrators and infrastructure operators managing the CRS354-48P-4S+2Q+RM in enterprise environments and data centers where power supply replacement must be fast and without operational impact. Direct compatibility with the switch's internal slot guarantees immediate mechanical and electrical integration without modifications.

G1270 delivers two independent outputs — 53V DC / 13.5A for the switch's high-voltage PoE ports and 26.5V DC / 27A for the low-voltage PoE ports — fully covering the 750W power budget required for simultaneously powering up to 48 connected PoE devices. The wide AC input range of 90–264V ensures global compatibility with any electrical grid without additional adapters. The Open Frame form factor allows direct integration into the CRS354-48P-4S+2Q+RM enclosure according to original MikroTik specifications.

The CRS354-48P-4S+2Q+RM ships with two power supplies for N+1 redundancy — when one fails the other takes over the load, but redundancy is lost until replacement. Keeping a G1270 in stock eliminates dependency on delivery lead times during an incident and allows full redundancy and the complete PoE budget to be restored within minutes without a planned maintenance window.

Recommended as a standard spare component for any active installation with CRS354-48P-4S+2Q+RM in enterprise environments, data centers, and telecommunications infrastructures where the full PoE power budget and power redundancy are critical operational requirements. Suited for technical teams maintaining spare parts inventories for high-power PoE switches, and for any deployment where continuous power delivery to 48 PoE ports without downtime is a priority.
