There a fix for ya

When an HP T700 or HP XR5500 Uninterruptible Power Supply (UPS) is connected to a ProLiant ML150 G2 server through the serial port using a serial cable, the CPU utilization will remain constant at 100 percent. As soon as the serial cable is removed, the CPU utilization immediately returns to normal levels.

Any ProLiant ML150 G2 server running System ROM Version 1.10 (or earlier) and is connected to a HP T700 or HP XR5500 Uninterruptible Power Supply (UPS) via a serial cable.

To prevent the processor utilization from immediately increasing to 100 percent when a UPS is connected to the serial port, upgrade the ProLiant ML150 G2 System ROM using the Single Point Solution Systems ROMPaq Firmware Upgrade Diskette for HP ProLiant ML150 G2 Servers, available at the following URL:
