1.4.10 Resetting a Board
During device maintenance, you can use a certain command to reset a board. Before resetting a
board, you need to save the configuration file on the board to ensure that the configuration can
automatically recover after the board is reset.
Background Information
When an operating board of the device fails, you are recommended to reset the board by using
the reset slot command.
WARNING
You need to back up important data before resetting a board.
Procedure
Step 1 Run the reset slot slot-id [ card card-id ]command in the user view to reset the faulty board or
subcard.
NOTE
lIf this command is run to reset a master MPU and no slave MPU exists, the master MPU is reset with
the CPU being powered on. If a slave MPU exists, this command performs the master-slave MPU
switchover.
lIf the board is still abnormal after being reset, contact Huawei technical support personnel.

The cleaning cycle for the air filtered is configured.
NOTE
The air filter is a component without memory. All the monitored information is saved on the MPU, which
may be inserted, removed, switched, or replaced during usage. Therefore, the monitoring cycle may differ
from the set cycle, but this does not affect the monitoring function.
----End
1.5.2 Remonitoring the Cleaning Cycle of the Air Filter
Context
The system generates an alarm about cleaning the air filter. After ensuring that the air filter is
cleaned or does not need to be cleaned, you need to clear the alarm and remonitor the cleaning
cycle of the air filter.
Do as follows on the router:
Procedure
Step 1 Run:
reset dustproof run-time
The alarm is cleared. The cleaning cycle of the air filter is monitored.
----End
1.5.3 Checking the Configuration
Procedure
Step 1 Run:
display dustproof
Information about the air filter is displayed.
----End
Example
Run the display dustproof command. You can view information about the cleaning cycle of
the air filter, the last time when the air filter was cleaned (referring to the time on the router),
how many days the router had been run since the previous cleaning, and how long the alarm
about cleaning the air filter exists. For example:

1.6 Configuration Examples
This section provides several examples for maintaining the router.
1.6.1 Example for Powering Off the MPU
When the MPU fails or needs maintenance or a hardware upgrade, you need to power off the
board. Then, you can remove the board.
Networking Requirements
After checking the alarm information, you find that the hardware on the master MPU fails. Then,
power off the master MPU and check it.
Configuration Notes
CAUTION
On a single NE5000E, interfaces are numbered in the format of slot number/sub-card number/
interface number; whereas in the multi-chassis scenario, interfaces are numbered in the format
of chassis ID/slot number/card number/interface number. This requires the chassis ID to be
specified along with the slot number.
The NE5000E cannot work with a single MPU for a long time. If the MPU fails, the whole
system is broken down. After the slave MPU is powered off, you must finish required operations
and restore the MPU immediately.
Configuration Roadmap
The configuration roadmap is as follows:
1. Switch the master MPU to the slave MPU.
2. Power off the slave MPU.
Data Preparation
To complete the configuration, you need the following data:
lSlot number of the master MPU
Procedure
Step 1 Perform a master/slave switchover on the router.

Before performing the master and slave switchover, check that user interfaces such as AUX,
console, and VTY interfaces are connected to the two MPUs. Otherwise, users that use the
interfaces connected with the former master MPU automatically quit the login after the master
and slave switchover.

Step 2 Power off the MPU in slot 18.
<HUAWEI> power off slot 18
Step 3 Verify the configuration.
Check the registration status of the MPU. You can view that the MPU in slot 18 is in the
unregistered and abnormal state. It means that the MPU is powered off.
