The MPUs support the clock that complies with IEEE 1588v2.
l
System maintenance unit
The system maintenance unit of the MPU collects monitoring information, remotely or
locally tests system units, or performs in-service upgrades on system units.
Through the Monitorbus, the MPU collects the operation data periodically. The MPU
produces controlling information, such as detecting the board presence and adjusting the
fan speed.
NOTE
The MPUs work in 1:1 hot backup mode, improving system reliability.

Indicator/
Button
Description
STAT indicator
If the indicator is steady green, the MPU is working properly.
If the indicator blinks green, the MPU is being registered.
If the indicator is steady red, the hardware of the MPU is faulty.
If the indicator is off, the MPU is not powered on or fails to be registered.
ACT indicator
If the indicator is steady green, the MPU functions as the master MPU.
If the indicator is off, the MPU functions as the slave MPU or is not
registered.
ETH LINK
indicator
If the indicator is steady green, the ETH link is Up.
If the indicator is off, the ETH link is Down.
ETH ACT
indicator
If the indicator blinks yellow, data is being transmitted.
If the indicator is off, no data is being transmitted.
