1 Introduction
This guide describes how to install a power supply upgrade kit, HP Product
Number D8551A, in an HP NetServer LH 3000/3000r or an HP NetServer
LH 6000/LH 6000r.
The power supply upgrade kit provides a redundant power supply that allows the
NetServer to keep operating should one of the original power supplies fail. The
redundant power supply fan module, also shipped with the upgrade kit, provides
additional cooling and allows the NetServer to keep operating in case the original
fan module fails.
After installing the power supply upgrade kit, you can remove and replace a failed
power supply without powering down the NetServer.
CAUTION If you remove a power supply on a hot-swap basis, you must
immediately install a replacement power supply or a power
supply filler panel to prevent overheating problems.
Removing a power supply on a hot-swap basis bypasses the
cooling air around the adjacent power supply. Leaving a
power supply bay empty for too long can cause the remaining
power supplies to overheat and may cause a system shutdown.
