Fortinet Fortiswitch AC Power Supply AC Power Supply FOR FS-548D AND FS-524D. - FS-PSU-150

Fortinet FS-PSU-150 Redundant AC Power Supply for FortiSwitch

Overview

The FS-PSU-150 is a redundant AC power supply module designed to eliminate single-point-of-failure risk on high-density FortiSwitch deployments. Installing a second FS-PSU-150 alongside the primary PSU keeps the switch running if one supply fails — no downtime, no manual intervention required. This is the accessory to spec when uptime requirements rule out any single-component failure bringing down an aggregation or distribution layer switch.

Compatibility

The FS-PSU-150 is purpose-built for two specific FortiSwitch models: the FS-548D (48-port 10GbE SFP+ aggregation switch) and the FS-524D (24-port 10GbE SFP+ switch). These are the only validated platforms — do not attempt to install this module in other FortiSwitch families. If you are deploying Fortinet switches outside this pair, verify your specific model's PSU compatibility against the FortiSwitch hardware guide before ordering. For broader network switch power redundancy options across other vendors, check the full power supply category.

Installation Notes

The FS-PSU-150 installs into the dedicated redundant PSU bay on the FS-548D or FS-524D — hot-swap capable, so insertion does not require powering down the switch. Confirm your switch chassis has an open PSU slot before ordering; only one redundant bay is available per chassis. Secure the module until the latch clicks and verify the front-panel PSU status LED shows green before considering the installation complete. Consult the FortiSwitch hardware guide for torque requirements on the retention screw if applicable to your chassis revision.
