H3C CR-19K-MPU-16A main processing unit
1 Identifier
The module identifier CR-19K-MPU-16A is on the far right of the front panel.
2 About the MPU
The CR-19K-MPU-16A main processing unit (MPU) provides the following functionalities:
· Route calculation and forwarding table maintenance.
· System configuration, control, and monitoring. On the MPU, you can monitor, upgrade software, and reset a module.
· High-precision clock and time synchronization.
· Real-time clock (RTC) that keeps tracks of the current time, providing seconds, minutes, hours, day, date, month, and year information.
· Support for active/standby switchover when two MPUs are installed on the router.
IMPORTANT: If you install two MPUs for the router, make sure they are the same model. |
