Page 104: Appendix D Uninterruptible Power Supply
Appendix D: Uninterruptible Power Supply 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 the Raid 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. -

Galaxy Raid GHDX2-2430S-16U4D Installation and Hardware Reference Manual D.4 Connecting the UPS to the Subsystem D.4.1 Connect the PSU Module Power Cords The two (2) power cables shipped with the subsystem must be plugged into the power cord sockets in the rear of the PSU modules. The plug at the other end of the power cable must be inserted into a socket on the UPS. -
Page 106: Power On
Appendix D: Uninterruptible Power Supply D.5 Power On When powering on the subsystem, the UPS must be powered on before the subsystem. For instruction on how to power on the UPS, please refer to the documentation that came with your UPS. Note that the power on sequence described in Chapter 4 will be altered. -
