Infortrend EONSTOR A16E-G2130-4 User Manual
Appendix D
Uninterruptible Power Supply
D.1 Uninterruptible Power Supply Overview
An uninterruptible power supply (UPS) is a separately purchased battery
backup unit that is connected to an Infortrend subsystem. If the UPS is
sufficiently large, it should allow the whole subsystem to safely finish the
ongoing I/Os in the event of an AC power failure.
D.2 Compatible UPS Supplies
The APC SMART-UPS 700VA is compatible with the EonStor subsystem.
D.3 Serial Communication Cable
Part Number: IFT-9270CUPSCab
The subsystem is shipped with a customized audio-jack to DB9 serial
communication cable. The cable is used to connect the controller module on
a subsystem to a PC hyperterminal for subsystem management. If you wish
to use a UPS with your subsystem, an additional audio-jack to DB9 serial
communication cable (see Figure D-1) must be purchased.

CAUTION!
The pinouts on the COM2 audio-jack to DB9 serial cable used to connect
to the UPS are different from the pinouts on the serial cable that was
shipped with the subsystem. When connecting the UPS device, please
make sure you use the correct cable type. The cable pinouts are listed in
Appendix C.
