Replacing the Air Filter

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 lbs (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.
  2. Turn the screw to the left on the fan tray door. Open it to the right and remove it.

  4. Locate the up arrow on the replacement filter to ensure that the air filter is right side up.
  5. Slide the air filter straight into the chassis until it stops.
  6. Replace the fan tray door and tighten the screw to secure it in the chassis.
