Power supply Mikrotik 12VDC 27.5A 350W hot swap power supply for CRS804 DDQ

MikroTik G1394-0350WNA is a 350W hot-swap power supply module designed exclusively for the CRS804 DDQ switch, allowing complete power redundancy to be restored or a faulty unit replaced without powering down the device. It is deployed in data centers, enterprise racks, and telecommunications infrastructures where every second of downtime has a real operational cost and power interruption is not an option. It is the essential component for full N+1 power redundancy operation of the CRS804 DDQ switch.

The module accepts AC input 100–240V / 50–60Hz / 8A MAX, covering the full spectrum of global power grids without additional adapters. The stabilized output of 12VDC / 27.5A with a total power of 350W and auxiliary voltage of 5VSB / 4A ensures reliable and consistent power delivery to the switch under any load conditions. The compact 40×50.5×220 mm form factor is designed for direct insertion into the dedicated slot of the CRS804 DDQ without modifications or adapters, guaranteeing full mechanical and electrical compatibility.

Hot-swap functionality allows the module to be installed or replaced while the switch is operating at full capacity, with no impact on network traffic or active services. Combined with the second power slot of the CRS804 DDQ, it provides complete N+1 redundancy — if one module fails, the second immediately takes over the full load without manual intervention. Keeping a spare module in stock eliminates dependency on delivery lead times during an incident and allows redundancy to be restored within minutes.

Recommended for data centers and enterprise racks operating the CRS804 DDQ in high-availability mode, telecommunications infrastructures with strict uptime requirements, and critical laboratories where service continuity is mandatory. Suitable as a standard spare component for any active CRS804 DDQ installation and for any deployment where full power redundancy and downtime-free replacement are mandatory operational requirements.
