Q.
Does the router support active/standby MPU switchover?
A.
Yes. The standby MPU automatically takes over when the active MPU fails to ensure service
continuity.
For a successful active/standby switchover, make sure the active and standby MPUs use the same
software version.
Q.
What is the operating temperature and upper and lower temperature thresholds of the router?
A.
The operating temperature of the router is in the range of 0°C (32°F) to 45°C (113°F).
You can use the
display environment
command to display the router temperature statistics,
including the current temperature and temperature thresholds.
•
When the temperature drops below the lower threshold or reaches the warning threshold, the
router displays a log message and a trap.
•
When the temperature reaches the alarm threshold, the router repeatedly displays log and trap
messages. It also alerts the user to the high-temperature condition through LEDs on the panel.
Q.
How do I identify the card serial number or manufacture information?
A.
Use the
display device manuinfo
command on the router. The following is a sample command
output.
<H3C>display device manuinfo
