MNT Ports/RMT Ports/FST Ports
The MNT port is used for operation management and the FST port is used for maintenance. The RMT port is used
to separate the network from the MNT port for operation management.
FST ports are available for the ETERNUS AF650 S3.
The specifications for the MNT port, the RMT port, and the FST port are shown below.

Battery (ETERNUS AF650 S3)
Two batteries are installed in the controller enclosure as backup power supply sources in case of power outage.
The batteries are charged from an external power source while the ETERNUS AF is running normally. If a power
failure is detected, the cache data in the system memory is saved to the BUD in the controller by using battery
power. There is no limit to the post-failure data retention time.
