NonStop NS1200 Planning Guide

NOTE: If your system includes the optional rackmounted HP R5500 XR UPS, the modular
cabinet will have one PDU located on the rear left side and four extension bars on the rear right
side. To provide redundancy, components are plugged into the left-side PDU and the extension
bars. Each extension bar is plugged into the UPS.
Power and current specifications for each type of enclosure are:

1 Half of the plugs for an enclosure must be connected to the left-side PDU and the other half connected to the right-side
PDU or extension bars (if the optional UPS is installed). PDUs must be supplied from separate branch circuits.
2 Total apparent power is the sum of the two AC power lines feeding the enclosure. Electrical load is shared equally
between the two lines.
3 Measured with PICs installed in slots 1, 2, 5, 6a/7a, 7b, and 7c; PIC in slot 7c had two external connections. Sysex
was running. Fans were running at full speed.
4 Measured with 14 disk drives installed and active.
5 Maintenance switch has only one plug. If a UPS is installed in the modular cabinet, the maintenance switch plug
must be connected to the extension bars on the right side of the modular cabinet.
