Redundant Power Supplies for Use with
Your Switch
The 5320 Series extended temperature (XT) switches contain a xed 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 on page 71.
LEDs on the external redundant power supply provide information on the unit's
operational status. See External Redundant Power Supply LEDs on page 93 for details.
