Replacing the Air Filter on the SRX3400 Services Gateway
The services gateway has one air filter that installs vertically in the rear of the chassis.
The air filter is hot-insertable and hot-removable.
The air filter is located in the rear of the chassis on the right side. The air filter weighs
approximately 0.2 lb (0.09 kg).
CAUTION: Do not run the services gateway 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 strap to one of the ESD points on the chassis. For more information
about ESD, see Preventing Electrostatic Discharge Damage to the SRX3400
Services Gateway.
2. Turn the screw to the left on the fan tray door. Open it to the right and remove
it.
