Replacing the Air Filter of the NIP6830

Replacing the Air Filter of the NIP6830

This section describes the procedure for replacing the air filter on the NIP6830.


To ensure proper heat dissipation and ventilation for the system, and to prevent the accumulation of dust on the air filter, you need to clean the air filter regularly. It is recommended that an air filter be cleaned at least once every three months and be replaced once every year. When an air filter is placed in the dusty environment such as an equipment room, the air filter should be cleaned more frequently.

The method for replacing an air filter of the NIP6830 chassis configured with DC power supply is the same as that of replacing an air filter on a chassis configured with AC power supply.

Configuring a Cleaning Cycle for the Air Filter

You can configure a cleaning cycle for the air filter on the chassis using the dustproof check-timer day days command in the system view.

When the air filter has already been running for a period of time, the system generates an alarm to remind you to clean the air filter. You can use the reset dustproof run-time command to clear the alarm and re-count the runtime of the air filter. The default cleaning cycle is 90 days. The value 0 indicates that the air filter monitoring is stopped.


The air filter does not have memory. All monitored information is saved on the MPU, which may be inserted, removed, switched, or replaced at any time. Therefore, the monitoring cycle may differ from the set cycle. However, this does not affect the monitoring function.


Before replacing an air filter, you need the following tools:

  • ESD wrist strap or ESD gloves

  • Phillips screwdriver


  1. Check the location of the air filter to be replaced.

    Before pulling out an air filter that is to be replaced, check its location, that is, the cabinet and chassis where the air filter resides and then label the air filter.

  2. Put on the ESD wrist strap and connect the grounding terminal to the ESD jack on the rack.
  3. Remove the air filter from the air intake frame.
    1. The air filter is located behind the device. Loosen the captive screws on the panel on the rear of the device, as shown in Figure 3-38 (1).
    2. Holding the panel of the air filter, slowly pull the air filter out until it leaves the chassis, as shown in Figure 3-38 (2).

  4. Install a clean and dry air filter in the air intake frame.
    1. Insert the clean and dry air filter into the chassis, as shown in Figure 3-39 (1).
    2. Fasten the captive screws onto the panel of the air filter, as shown in Figure 3-39 (2).

Follow-up Procedure

  • Gather up and store the tools.
  • Dispose of the replaced air filter according to the compliance and safety standards.
