SRX240 Services Gateway Power Supplies

This topic includes the following sections:

AC Power Supply

The SRX240 Services Gateway with AC power supply models use a fixed, internal AC power supply. The power supply distributes different output voltages to the services gateway components according to their voltage requirements. The power supply is fixed in the chassis and is not field-replaceable.

The AC power supply has a single AC appliance inlet that requires a dedicated AC power feed.

DC Power Supply

The SRX240 Services Gateway with DC power supply models have a fixed, internal DC power supply. The DC power supply, which is installed on the back panel of the chassis, has dual redundant power feeds and provides full power redundancy for the services gateway. The power supply is fixed in the chassis and is not field-replaceable.

The DC power feed has a terminal block that provides a single DC input (–48 VDC and return) and requires a dedicated 10 A (–48 VDC) circuit breaker. The DC power feed includes two LEDs that indicate the status of the power supply. For more details about the LEDs, see SRX240 Services Gateway LEDs.

Note: Each power feed requires a dedicated circuit breaker to be a fully redundant DC source.

Note: DC-powered devices are intended for installation only in a restricted access location.
