xvi PC Server 520 User's Handbook for PCI/Micro Channel

Chapter 1. Introducing PC Server 520 Features
Your PC Server 520 has an Intel Pentium microprocessor and
symmetric multiprocessing (SMP) upgradability, a PCI advance bus,
an integrated SCSI-2 Fast/Wide Controller, large data-storage
capacity, and improved system expandability. This server is
specifically designed by IBM to handle heavy file-server applications
or moderate database applications in today's network environment.
Using Micro Channel and peripheral component interconnect (PCI)
architectures, it provides compatibility with a wide range of existing
hardware and software. Super video graphics array (SVGA)
support provides compatibility with many existing application
programs.
Your server offers dual-processor capability through a second
microprocessor connector so that you can take advantage of SMP
technology. If you have an SMP-capable operating system, you can
maximize the benefits of this technology,
As an open-architecture, industry-standard system, the PC Server
520 has been tested with numerous IBM and non-IBM adapters and
devices to assure compatibility. Rugged dependability is achieved
by incorporating quality standards and design points, such as
stringent IBM systems assurance testing and a cooling design called
FloThru. FloThru cooling helps keep internal electronic components
of the PC Server 520 running cool to improve reliability and
accommodate the full configurations necessary in today's local area
network (LAN) environments.
Refer to the Setup sheet for instructions on unpacking the server
and attaching cables to it.
See Chapter 2, “Installing Your Software” on page 19 for
information on installing an operating system and other software.
In addition, this book provides information on configuring and
using the server, installing and removing options, and using the
system programs that are provided. The troubleshooting
information will help you solve some of the simpler problems that
might occur. Appendix A in this book provides a section for you to
record all the important information about your server.

Before You Begin
Before You Begin
Make sure you have an adequate number of properly grounded
electrical outlets for your server, monitor, and any other options
that you intend to install.
Place your server in a location that is dry. Rain or spilled
liquids might damage your server.
Leave about 51 mm (2 in.) of space around the front and rear of
your server to allow the server's cooling system to work
properly.
Have a supply of 1 MB and 2 MB, 3.5-inch diskettes available.
You will need these diskettes later, when you install your
operating system and backup your configuration and all
important data.
Have small, flat-blade and Phillips screwdrivers available.
If you have not already done so, perform the following tasks.
Instructions are located on the Setup sheet that comes with your
server.
Unpack your server.
Remove the packing material.
If you are not installing options at this time, connect the cables
and power cord.
After you complete these tasks, return here for further instructions.
Note: For information about arranging your PC Server for comfort
and ease-of-use, see “Arranging Your Workspace” on
