Monitoring the SRX240 Services Gateway Power System

 

This topic includes the following sections:

Monitoring the SRX240 Services Gateway AC Power System

The LEDs on the SRX240 Services Gateway enable you to determine its performance and operation. The Power LED, located on the front panel of the services gateway, indicates different conditions with respect to the power system.

Table 1 describes different Power LED indications and the required corrective actions.

Table 1: Services Gateway Power LED Status

LED Status

Meaning

Possible Cause and Corrective Action

Green

The services gateway is receiving power, and the internal power supply is functional.

Normal indication. No action is required.

Yellow

The Power button has been pressed and quickly released. The services gateway is shutting down or starting up.

Normal indication. No action is required.

Off

The services gateway is not receiving power.

  • Verify that the AC power cord from the power source to the services gateway is not damaged. If the insulation is cracked or broken, immediately replace the cord or cable.

  • Ensure that the socket you plug in is in working condition.

  • Ensure the services gateway has an AC input voltage between 110 and 240 VAC.

  • If you cannot determine the cause of the problem or need additional assistance, contact the Juniper Networks Technical Assistance Center (JTAC).
