Installing Internal Add-On Components

This section explains how to install internal add-on components into A-Class servers.
Internal add-on components include memory, cache memory, embedded disks and I/O
cards. For cabinet mounted servers, it is necessary to remove the server from the cabinet
to install internal add-on components.
Refer to the appropriate section for internal add-on component installation information:

Installing Memory (RAM) Modules.

This section describes how to install memory (RAM) into A-Class servers. Computer
memory is commonly referred to as Random Access Memory (RAM). The terms RAM and
memory are used interchangeably in this documentation. Abbreviated Memory SIMM
installation instructions also appear on the 11" x 14" maintenance label adhered to the
bottom of the top cover.
A-Class memory is sold as a module. A module is defined as two SIMMs. A-Class servers
support three memory module sizes: 128MB, 256MB and 512MB. The 128MB memory
module consists of two 64MB SIMMS. The 256MB memory module consists of two
128MB SIMMs and the 512MB memory module consists of two 256MB SIMMs. A
memory module occupies two slots. The size (or capacity) of a memory SIMM is printed
along the top edge of the SIMM.
SIMM is an acronym for Single Inline Memory Module. A SIMM has components on one
NOTE
side of the card, only.DIMM is an acronym for Dual Inline Memory Module. A DIMM has
components on both sides of the card.The acronym SIMM will be used throughout this
section to refer to either SIMM or DIMM.
A-Class servers provide 8 slots for memory. These slots are labeled in pairs and are
numbered 0a, 0b, 1a, 1b, 2a, 2b, 3a and 3b. The nomenclature for a pair of SIMM slots is
0a/b, 1a/b, 2a/b and 3a/b. The following rules govern the installation memory in A-Class
Servers.
