■

LAN ports

Two LAN ports (RJ-45) are installed in each controller.

●

Regions other than EMEA&I

Each LAN port is used for operation management (MNT port) and for remote support function 
(RMT port) respectively.

●

EMEA&I region

SCU

A System Capacitor Unit (SCU) is installed in a controller as a backup power source in case of 
power outage.
The SCU is charged from an external power source while the ETERNUS DX Disk storage sys-
tem is running normally. If a power failure is detected, data in the cache memory is saved to the 
non-volatile memory in the controller using the SCU. There is no limit to the post-failure data 
retention time.

■

PWC ports

A PWC port is installed in a controller.
The PWC port is used to connect a power synchronized unit to perform power synchronization.

The following table shows the PWC port specifications.
