Replacing the Air Filter on the SRX240 Services Gateway

 

The SRX240 Services Gateway High Memory with DC Power Supply model and SRX240 Services Gateway High Memory with AC Power Supply model has one air filter that installs vertically in the rear of the chassis. The air filter is hot-insertable and hot-removable.

Note

An air filter is not shipped with the SRX240 Services Gateway High Memory with AC Power Supply model. To meet NEBS requirements, you must order the air filter separately. Contact your Juniper Networks customer service representative for more information.

The air filter is located in the rear of the chassis on left side (from rear side view). The air filter weighs approximately 0.2 lb (0.09 kg).

Caution

Do not run NEBS-compliant services gateways (the SRX240 Services Gateway with DC Power Supply model and the SRX240 Services Gateway with AC Power Supply models) for more than a few minutes without the air filter in place.

Caution

Always keep the air filter in place while the device is operating, except during replacement. Because the fans are very powerful, they could pull small bits of wire or other materials into the device through the unfiltered air intake. This could damage the services gateway components.

To replace the air filter:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the other end of the ESD strap to the ESD point on the rack.
  2. Loosen the thumb-screw on the air filter. See Figure 1.

Note

When you are inserting an air filter for the first time on the SRX240 Services Gateway High Memory with AC Power supply model, you must remove the air filter cover by removing the screw on the cover using a number-1 Phillips screwdriver.
