Preface
Introduction
The HP NetServer LXr 8000 is an Intel-CPU based network server that
can use up to 8 GB of memory. This memory is situated on two boards
that communicate with the rest of the NetServer via the midplane
connector.
Each memory board can hold up to 4 GB of memory, arranged in four
banks of four buffered DIMMs. These DIMMs can be 64 MB or 256
MB, 50 ns EDO memory.
The standard configuration of memory is 256 MB on the primary (right)
board, as four 64 MB DIMMs in slots J1 through J4. Add memory four
DIMMs at a time. If you use both boards, each must have the same type
and number of DIMMs in the same slots.

1 Preparing for Installation
Verify Contents
CAUTION Do not remove the DIMM from its bag until you are
ready to install it. Make sure the bag remains sealed.
The DIMM is sensitive to humidity, so desiccant has
been packed in the bag containing the DIMM. When
the DIMM has been installed and the HP NetServer is
running, it is no longer sensitive to humidity.
Unpack the shipping box and verify that you received the contents listed
below for the Memory Upgrade Kit.
The upgrade kit includes:
•Four DIMM memory modules, either 64 MB or 256 MB buffered
EDO DIMMs (50 ns)

you are ready to install it.
