SRX240 Services Gateway Power Supply

This topic includes the following sections:

AC Power Supply (SRX240 Services Gateway Low Memory, High Memory, PoE, and Integrated Convergence Services Models)

The SRX240 Services Gateway uses an internal, fixed AC power supply. The power supply distributes the different output voltages to the device 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 (SRX240 Services Gateway High Memory with DC Power Supply Model)

The SRX240 Services Gateway High Memory with DC Power Supply model has an internal, fixed DC power supply. The DC power supply available on the back panel of the chassis has dual redundant power feeds and provides full power redundancy in the device.

The DC power supply 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 to indicate the status of the power supply. For more details about the LEDs, see SRX240 Services Gateway LEDs.

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

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