You can incorporate the integrated battery backup into a computer room emergency power off (EPO) system. Otherwise, volatile data can be lost.
When the integrated battery backup is installed and the room EPO is reset, the batteries engage and the computer continues to run. It is possible to attach the computer room EPO system to the machine EPO. When this is done, resetting the room EPO disconnects all power from the power cords and the internal battery backup unit. In this event, all volatile data will be lost.
To incorporate the integrated battery backup into the room Emergency Power Off systems (EPO), a cable must connect to the back of the system EPO panel. The following figures illustrate how this connection is made.
The preceding figure illustrates the back of the machine UEPO panel with the room EPO cable plugging into the machine. Notice the switch actuator. After it is moved to make the cable connection possible, the room EPO cable must be installed for the machine to power on.
In the following figure, an AMP connector 770019-1 is needed to connect to the system EPO panel. For room EPO cables using wire sizes #20 AWG to #24 AWG, use AMP pins (part number 770010-4). This connection should not exceed 5 Ohms, which is approximately 61 m (200 ft.) of #24 AWG.
