SRX2300 Cooling System Maintenance

SUMMARY Maintaining the SRX2300 includes removing and installing the fans.

The SRX2300 has four independent, field-replaceable fans at the rear of the chassis.

Each fan module is a hot-removable and hot-insertable field-replaceable unit (FRU). You can remove and replace the fans without turning off power to the appliance or disrupting its functions.

Before you replace a fan:

  • Ensure that you understand how to prevent ESD damage.

  • Ensure that you have the following parts and tools:

    • Electrostatic discharge (ESD) grounding strap

    • An antistatic bag or an antistatic mat

    • A replacement fan module

    • A Phillips (+) screwdriver, number 1 or 2 (optional), for the captive screws

Remove the Fan Module from the SRX2300

CAUTION:

Do not remove a fan unless you have a replacement fan available.

To remove a fan:

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to one of the ESD points on the chassis.
  2. Place the antistatic bag or the antistatic mat on a flat, stable surface.
  3. Loosen the captive screws on the front faceplate of the fan module by using your fingers. If you can't loosen the captive screws by using your fingers, use the screwdriver.
    Warning:

    To prevent injury, do not touch the fan with your hands or any tools as you slide the fan module out of the chassis—the fan might still be running.
  4. Grasp the handle on the fan module and pull it firmly to slide the fan module out of the chassis.
