· Insert dust plugs into open fiber ports and transceiver module ports to protect them from contamination and ESD damage.

Examining the installation site

The router must be used indoors. To ensure correct operation and long service life of your router, make sure the installation site meets the following requirements.

Temperature and humidity

To ensure correct operation and long lifespan of the router, make sure the temperature and humidity in the equipment room meet the requirements as described in Table1-1.

· Lasting high relative humidity tends to cause poor insulation, electricity leakage, mechanical property change of materials, and corrosion of metal parts.

· Lasting low relative humidity is likely to cause washer contraction and ESD and cause problems including loose mounting screws and circuit failure.

· A high temperature is the most undesirable condition, because it accelerates the aging of insulation materials and significantly lowers reliability and service life of the router.

To install 50G or 100G transceiver modules on the device, make sure the following operating temperature requirements are met:

· When you install 50G/100G transceiver modules on the device, the operating temperature range for the device depends on these transceiver modules. This can ensure the operation of the transceiver modules. The original operating temperature range is –20°C to +60°C (–4°F to +140°F) for the device and 0°C to 70°C (+32°C to +158°F) for the transceiver modules. For more information about 50G or 100G transceiver modules, see H3C 5G IPRAN Access Router Series Transceiver Module Compatibility Matrix.

· To ensure the operation of transceiver modules when you install the QSFP-100G-ZR4-WDM1300 transceiver module, make sure the operating temperature is 0°C to 40°C (+32°C to +104°F) for the device.

When you install a card in slot 9 on the RA5300-AC device, make sure the following operating temperature requirements are met:

· When 50G commercial transceiver modules with a maximum transmission distance of 10 or 40 km (6.21 or 24.86 miles) are installed, make sure the operating temperature is 0°C to 45°C (+32°C to +113°F).

· When 25G/10G/1G commercial transceiver modules with a maximum transmission distance of 10, 40, or 80 km (6.21, 24.86, or 49.71 miles) are installed, make sure the operating temperature is 0°C to 50°C (+32°C to +122°F).

If the actual temperature exceeds the stated range, use appropriate industrial-grade transceiver modules to ensure their stable operation.

To display transceiver module information:

Task	Command	Remarks
Display key parameters of transceiver modules.	display transceiver interface [ interface-type interface-number ]	Available for all transceiver modules.

Diagnosing transceiver modules

The router provides the alarm and digital diagnosis functions for transceiver modules. When a transceiver module fails or is not operating correctly, you can perform the following tasks:

· Check the alarms on the transceiver module to identify the fault source.

· Examine the key parameters monitored by the digital diagnosis function, including the temperature, voltage, laser bias current, TX power, and RX power.

To diagnose a transceiver module:

Task	Command	Remarks
Display transceiver alarms.	display transceiver alarm interface [ interface-type interface-number ]	Available for all transceiver modules.

For more information about transceiver module-rated commands, see the command references for the router.

Saving the running configuration

IMPORTANT:

You must save the running configuration to a .cfg configuration file.

You can use one of the following methods to save the running configuration:

· Fast mode—Use the save command without the safely keyword. In this mode, the router directly overwrites the target next-startup configuration file. If a reboot or power failure occurs during this process, the next-startup configuration file is lost. You must specify a new startup configuration file after the router reboots.

· Safe mode—Use the save command with the safely keyword. Safe mode is slower than fast mode, but more secure. In safe mode, the system saves the configuration in a temporary file and starts overwriting the target next-startup configuration file after the save operation is complete. If a reboot or power failure occurs during the save operation, the next-startup configuration file is still retained. Use the safe mode if the power source is not reliable or you are remotely configuring the router.

To save the running configuration:

Task	Command	Remarks
Save the running configuration to a configuration file, without specifying the file as a next-startup configuration file.	save file-url [ all \| slot slot-number ]	Use either approach. Available in user view.
Save the running configuration to a configuration file in the root directory of the active and standby RSU storage medium, and specify the file as a next-startup configuration file.	save [ safely ]

save [ safely ]

Rebooting the router or a module

CAUTION:

· If the main system software image file is damaged or does not exist, do not use the reboot command to reboot the router. Specify the main system software image file first, and then reboot the router.

· The precision of the rebooting timer is 1 minute. 1 minute before the rebooting time, the router prompts "REBOOT IN ONE MINUTE" and reboots in one minute.

· If you are performing file operations when the router is to be rebooted, the system does not execute the reboot command for security.

To reboot the router or a module, use one of the following methods:

· Reboot the router at the CLI.

¡ Reboot the router immediately by using the reboot command.

¡ Schedule a reboot to occur at a specific time or date or after a delay by using the schedule reboot command.

· Power off and then power on the router. This method cuts off the power of the router forcibly, which might cause data loss and hardware damage. It is the least-preferred method.

To reboot a module or the router immediately:

Task	Command	Remarks
Reboot a module or the router immediately.	reboot [ slot slot-number ]	If you do not specify the slot slot-number option, the command reboots the router. Available in user view.
