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.
