Replacing the Cooling System Air Filter on the SRX1400 Services Gateway

 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 services gateway 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.

Note

You can order an air filter kit separately. Contact your Juniper Networks customer service representative for more information. The air filter kit includes a cooling system air filter and four power supply air filters.

The services gateway cooling system has one air filter that installs in the rear of the chassis. The air filter supports hot-swappable functionality.

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).

To replace the cooling system air filter:

  1. Attach an 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 SRX1400 Services Gateway.
  2. Turn the screw to the left on the fan tray door. Open it to the right and remove it. See Figure 1

  3. Slide the air filter out of the chassis and properly dispose of 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 as shown in Figure 2.
