SRX1400 Services Gateway AC Power Supply

AC Power Supply Overview

In an AC power configuration, the SRX1400 Services Gateway contains one or two AC power supplies, located at the front panel of the chassis in slots PEM0 and PEM1. Each power supply provides power to all components in the services gateway. When two power supplies are present, they share power almost equally within a fully populated system. The two AC power supplies provide full power redundancy. If one power supply fails or is removed, the remaining power supply redistributes the electrical load without interruption.

Figure 15 shows the SRX1400 Services Gateway AC power supply.

Note: Only a redundant power supply supports hot-swappable functionality.

Color

Status

Condition Indicated

Green

On steadily

AC input voltage is present, and both main 12 V output and standby 3.3 V output are enabled and healthy.

Blinking

AC input voltage is present, standby 3.3 V output is on, but the main 12 V output is disabled. This condition usually indicates that the device has been powered off at the POWER button on the SYSIOC front panel. This condition can also indicate that either the SYSIOC or Routing Engine has been removed from the services gateway.

Amber

On steadily

The power supply has detected one or more of the following faults:

  • Power supply fan failure
  • Power supply over-temperature condition
  • Over-current or under-voltage condition on the standby 3.3 V output

Blinking

The power supply has detected one or more of the following faults:

  • Under-voltage condition on the 12 V output
  • Over-voltage condition on the 12 V output
  • Over-current condition on the 12 V output
