Replacing an Air Filter

Replacing an Air Filter

Context

To prevent the air filter of a switch from being blocked by dust and to ensure efficient heat dissipation, it is recommended that you replace or clean an air filter at least once every six months. When a switch is used in a dusty environment, clean or replace its air filter more frequently, for example, once every two weeks or one week.

The switches may use honeycomb air filters or non-honeycomb air filters. The switches with honeycomb air filters installed in all air filter slots comply with Federal Communications Commission (FCC) standards.

NOTE:

The methods for replacing the air filters on different models are the same. This section uses S12708 as an example to describe the replacement procedure.

Tools

  • Phillips screwdriver
  • ESD wrist strap or ESD gloves

Procedure

  1. Determine in which cabinet and chassis the air filter is installed, find the air filter in the chassis, and attach a label on the air filter to avoid misoperation.
  2. Wear an ESD wrist strap or a pair of ESD gloves. When wearing an ESD wrist strap, insert the other end in the ESD jack of a device and ensure that the device is reliably grounded.
  3. Remove the air filter.
    1. Use a Phillips screwdriver to loosen the captive screws on the air filter. See callout 1 in Figure 13-15.
    2. Slowly pull the air filter out. See callout 2 in Figure 13-15.

  4. (Optional) Dry clean the sponge air filter.

    1. Tap the air filter to remove thick dust.
    2. Vacuum the air filter.

    If the switch uses a honeycomb air filter, replace the air filter.

  5. Install the air filter.
    1. Slowly insert the air filter into the chassis. See callout 1 in Figure 13-16.
    2. Tighten the captive screws on the filter with the Phillips screwdriver. See callout 2 in Figure 13-16.
