MikroTik G1483-0600WNB Power Supply for Professional Networking Equipment

MikroTik G1483-0600WNB is a 600W hot-swap power supply at 54.5V / 10.35A for the CRS320-8P-8B-4S+RM PoE++ switch, designed either as a second PSU to expand the total power budget or as a replacement unit when the original fails. It is deployed by network administrators and infrastructure operators managing the CRS320-8P-8B-4S+RM in enterprise environments where powering high-draw PoE++ devices — PTZ cameras, screen-equipped phones, Wi-Fi 6 access points, or industrial equipment — requires an extended power budget or complete N+1 redundancy. Installation is performed without powering down the switch or interrupting network traffic.

The CRS320-8P-8B-4S+RM ships with a single 600W power supply and a dedicated expansion slot for a second PSU. Adding a second G1483-0600WNB raises the total available power to 1150W — sufficient to simultaneously power all 8 PoE++ ports at up to 90W per port, covering the requirements of the most power-demanding PoE++ equipment in professional infrastructures. The stabilized output of 54.5V / 10.35A provides the voltage required by the PoE++ 802.3bt standard for high-power delivery without degradation under maximum load.

Hot-swap functionality allows the PSU to be inserted or replaced while the switch operates at full capacity, with no impact on active PoE ports or data traffic. An MTBF of approximately 200,000 hours at 25°C — twice that of standard MikroTik power supplies — confirms superior reliability for continuous 24/7 operation in critical infrastructures. Direct compatibility with the CRS320-8P-8B-4S+RM expansion slot guarantees immediate integration without modifications.

Recommended for CRS320-8P-8B-4S+RM switches powering high-draw PoE++ equipment that require expanding the total budget to 1150W, installations where N+1 power redundancy is a mandatory operational requirement, and any deployment where hot-swap PSU replacement and long-term reliability are priorities. Suited as a standard spare component for any active CRS320-8P-8B-4S+RM installation where continuity of PoE++ power delivery cannot be compromised.
