Keep supported FortiSwitch systems online with a dedicated redundant AC power supply sized for network resilience. The FS-PSU-150 delivers 150 W of output power and supports 120 V AC input, giving infrastructure teams a purpose-built replacement or backup power option for compatible switches. This unit is specified for the FS-548D and FS-524D, which makes it a precise fit for environments that value predictable compatibility over generic substitutes. In a switch stack or access layer deployment, that matters: the right power module reduces integration risk and helps preserve service continuity when a primary supply fails. Because it is a redundant power supply, it is well suited to production networks where uptime is measured in business impact, not just technical metrics. The power cord is not included, so procurement teams can align cabling with site standards and existing inventory. Choose this power supply when you need a direct-fit AC module for supported FortiSwitch hardware and want to keep critical network infrastructure protected with a spare power path.
