The 5320 Series extended temperature (XT) switches contain a fixed internal AC power supply that supplies the power needed for most switch operations. XT switch models 5320-24T-4X-XT and 5320-24T-24S-4XE-XT provide the option to add an external redundant power supply (RPS) for power redundancy. These models support a 150 W external AC RPS (part no. RPS-150W-XT).
For information on installing an external AC RPS, see Install an External Redundant Power Supply.
LEDs on the external redundant power supply provide information on the unit's operational status. See External Redundant Power Supply LEDs for details.
