Juniper SRX300 Hardware Guide

Maintaining the SRX300 Services Gateway Power Supply
To maintain the power supply on the services gateway:
•
Make sure that the power and grounding cables are arranged so that they do not
obstruct access to other device components.
•
Routinely check the PWR LED on the front panel. If this LED is solid green, the power
supplies are functioning normally.
•
Periodically inspect the site to ensure that the grounding and power cables connected
to the services gateway are securely in place and that there is no moisture accumulating
near the services gateway.
CAUTION: We recommend using a surge protector for the power connection.
