How to use

Install the redundant PSU according to the equipment manufacturer’s instructions, connecting the unit to the switch or device redundant power input where provided. Ensure the AC mains cable is rated for the local supply and verify the input voltage is within the 100–240 V range before powering the unit. When used in a redundant configuration, connect both primary and backup power supplies and confirm the target device recognizes the redundant input. Replace units only when the system is powered down or following safe hot-swap procedures specified by the device vendor.

Usage recommendations

For reliable operation, place the PSU in a ventilated area free from excessive dust and moisture, use appropriately rated AC cables and connectors, and perform periodic inspections for secure connections. Verify compatibility with your specific Ubiquiti switch model before installation and keep a tested spare unit on hand for environments where continuous uptime is critical.
