USP-RPS

The UniFi SmartPower Redundant Power System, model USP-RPS, is a proprietary redundant power system designed to protect up to six UniFi SmartPower supported devices from sudden power supply module failure.

The USP-RPS continually monitors all attached devices. In the event of an internal AC/DC power supply failure, failover is automatic so your network continues to operate with no interruption in service.

With a 950W DC power budget, the USP-RPS can protect a variety of high-power devices, including UniFi PoE switches. An integrated 1.3″ color touchscreen LCM displays system information for convenient monitoring.

• (6) USP DC output ports
• (1) Ethernet port
• 1U Rackmountable (kit included)
• 1.3″ Touchscreen display with status information

With a 950W (12V 350W / 54V 600W) DC power budget, the USP-RPS can protect a variety of high-power devices, including UniFi PoE switches.

The following table lists the supported RPS models and their power budget.

Failover Mechanism
The USP-RPS automatically triggers a seamless failover in the event of an internal AC/DC power supply failure or AC circuit failure on the connected devices.

Power Architectures

Users can select different power architectures to protect the different levels of power failure.

• Internal power supply failure
• AC circuit failure
• Interruption of utility power

Single Port Power Overload
To prevent short circuiting, the USP-RPS monitors power continuously. If the power limit threshold is exceeded, the USP-RPS will cut off power on the port to protect the device and the port’s circuit.

PSU Power Overload
The primary purpose of the USP-RPS is to recover the device experiencing the internal power supply failure. For the resilience of power policy, the total backup power can be greater than the PSU capacity of the USP-RPS. In the event of an interruption of power for all devices, the pulse of power could be over the RPS PSU capacity.
