Maintaining the SRX320 Components

Required Tools and Parts for Maintaining the SRX320 Services Gateway Hardware Components

The following tools and parts are required to maintain the hardware components of the services gateway:

  • Electrostatic bag or antistatic mat

  • Electrostatic discharge (ESD) grounding wrist strap

  • Flat-blade screw-blade screwdriver, approximately 1/8 in. (3 mm)

  • Phillips (+) screwdrivers, numbers 1 and 2

Routine Maintenance Procedures for the SRX320 Services Gateway

For optimum performance of the services gateway, perform the following preventive maintenance procedures regularly:

  • Inspect the installation site for moisture, loose wires or cables, and excessive dust.

  • Make sure that airflow is unobstructed around the device and into the air intake vents.

  • Check the status LEDs on the front panel of the services gateway and on the Mini-Physical Interface Module (Mini-PIM) that you are using.

Maintaining the SRX320 Services Gateway Cooling System Components

The services gateway cooling system works to maintain an optimal temperature for the device. If the fan controller fails, the device temperature will exceed the maximum working temperature, and the device will fail. Ensure that you maintain the recommended clearances behind the device to enable the cooling system to function optimally.

Maintaining the SRX320 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.


We recommend using a surge protector for the power connection.

Replacing Mini-Physical Interface Modules in the SRX320 Services Gateway

The Mini-PIMs available on the SRX320 Services Gateway are not hot-swappable. You need to power off the device before removing or installing Mini-PIMs. For information on replacing Mini-PIMs, see SRX300 Series and SRX550 High Memory Services Gateway Interface Modules Reference.
