The quick hot-swap RAID
Cage may or may not be
included as a standard part
of the server configuration.
Quick Hot-swap RAID cage
The quick hot-swap cage allows you to configure a reliable RAID
subsystem. The quick hot-swap cage consists of a drive cage and all of the
necessary hardware to install it in the system. Each cage supports three
one-inch high 3.5-inch SCA SCSI drives. For optimum operation, use only
approved RAID-ready drives in the RAID Cage. The RAID Cage occupies
two standard half-height 5.25-inch drive bays.
Drives are mounted on a rail system which provides quick and easy
installation and hot-swapping. A fully functional RAID subsystem is
controlled by a RAID caching controller.
Hot-swapping is a useful features that allows you to replace a failed hard
disk drive without interrupting system operation. In the event of a
hot-swappable drive failure, which is part of a RAID 5, the system
22 Maintaining and Troubleshooting the Gateway ALR 7300 Server
continues normal operations. You can replace the failed drive and rebuild its
contents on an equivalent replacement drive automatically, without shutting
down the system.
Figure 9: RAID Cage
SCSI backplane components
The SCSI backplane connects the SCA-2 LVD SCSI drives to the SCSI
RAID controller or the SCSI controllers on the system board. The
backplane provides automatic SCSI address setting and allows
hot-swapping of SCSI drives. Figure 10 shows the back of the backplane
where the drives connect.

If the RAID cage is included as part of the server configuration, see the
Quick Hot-swap Installation Guide for information on how to configure the
quick hot-swap backplane.

Setting the jumpers
The system board jumpers let you change several system functions.
Jumpers are set to the default positions at the factory. You may need to
change the jumper settings to perform the following functions:
Set processor/bus speed settings
•
Clear CMOS memory
•
Processor speed jumper
The system board supports a range of processor speeds, which are set by
changing jumpers. If you upgrade your processor, you may need to change
jumper settings. The Processor Speed jumper (JP22) configuration block
lets you set the processor speed.
The system automatically detects the bus speed supported by the processor
and uses the jumper settings in conjunction with the detected bus speed to
set the processor speed. If two processors are present and they support
different speeds, the system operates at the slower speed. Move the jumper
shunts on jumper block JP22 to connect the jumper pins according to the
table below. Processor speeds are given in relation to bus speeds of
66MHz/100MHz.

Installing software and drivers
Installing software and drivers is usually specific to the operating system
you run on the system. However, some tips on installing drivers or other
software in critical situations or under particular circumstances are provided
below.
Installi ng the video driv ers
The integrated video controller on the system board uses standard drivers
provided with the system utilities diskettes. For those running Windows NT
in particular, use the driver provided on the utilities diskettes (Cirrus Logic
Windows NT 4.0 v1.40 diskette) not those provided on the Windows NT
installation CD-ROM. The drivers provided on the Windows NT CD-ROM
may not function correctly.
Video driver installation varies depending on the operating system that you
run on the server. Refer to the documentation for the operating system for
specific instructions.
If you are using an add-in video controller, the drivers should have
accompanied the controller card. See the documentation that accompanied

NetW are 4.11 driv ers and Seagate Bac kup Exec issues
NetWare 4.11 driver issues:
When installing the second instance driver for the second SCSI controller,
the server will generate interrupts which hang the server. To resolve this
issue, replace the MPS14.PSM file that is installed during the NetWare 4.11
installation with an updated version of the file. The updated file can be
obtained from the Netware Service Pack 5 utility patch provided by Novell.
The following are two methods that can be used to updated the
MPS14.PSM file:
1. After NetWare is installed and before loading the second on-board
SCSI driver, the updated MPS14.PSM f ile can be copied to the
C:\NWSERVER subdirectory to overwrite the older version placed
during installation. Restart the server and the second on-board SCSI
driver will load successfully.
2. During the NetWare installation, select SMP support, a message to
install an unlisted PSM file will display. Path to the location of the
updated PSM file and load it. Once loaded, the updated PSM file will
automatically be copied to the NetWare installation directory. Once
the file has been copied you can successfully load the second on-board
SCSI driver.
Seagate Backup Ex ec issues:
Once Seagate Backup Exec has been installed and the program started, the
CLIB and DSAPI modules report errors while loading. Backup Exec will
continue to run after the errors appear. Backup Exec recommends that these
files be updated to a later version. The updated files can be obtained from
Novell’s website at the following location:
http://support.novell.com/cgi-bin/search/download?/pug/updates/nw/i
nw411/libuph.exe&sr
The update files are CLIB.NLM and DSAPI.NLM.

About the BIOS Setup Utility
The computer BIOS has a built-in program that lets you set many basic
system characteristics. These settings are stored and saved even when the
power is off. This chapter contains information about this setup utility and
is intended to serve as a guide so that you can make changes to your system
BIOS when necessary.
Many of the screen examples that you see in this chapter are identical to
what you see on your monitor; however, you may have a system with a
newer BIOS version than the one described in this manual. In that case,
some of the examples may differ somewhat from what you see, but the
screens are similar enough that you should have no trouble getting the
information that you need.
Using the BIOS Setup Utility
The computer BIOS has a built-in setup utility that lets you configure
several basic system characteristics. The settings are stored in
battery-backed CMOS memory and are retained even when the power is
off.
To enter the setup utility, restart the system and then press
prompted on screen during the startup process. Upon entering setup, the
Main Setup screen opens.

Introduction
If your system does not operate correctly, re-read the instructions for the
procedure(s) you have performed. If an error occurs within an application,
consult the documentation supplied with the software.
This section identifies solutions to common problems. If the suggestions in
this chapter do not resolve your problem, try calling Technical Support.
Computer virus notice
A virus is a program written with malicious intent for the sole purpose of
creating havoc in a computer system. It attaches itself to executable files or
boot sectors, so it can replicate and spread. Some viruses may only cause
the system to beep or display messages or images on the screen. Other
viruses are highly destructive and corrupt or erase the contents of files or
disks. To be safe, never assume any virus is harmless.
Viruses are identified by how they infect the computer.
•
Program Viruse s
.EXE, .OVL, .DRV, .SYS, and .BIN.
•
Macro Viruses
viruses are written in the macro languages certain applications use
to enhance their functionality. These viruses do not infect other
programs or the boot sector.
•
Boot Viruses
FAT, or Partition Table.
•
Multipartite Viruses
infect executable program files such as.COM,
infect the data files of specific programs. These
attach themselves to a Boot Record, Master Boot,
are both program and boot infectors.
84 Maintaining and Troubleshooting the Gateway ALR 7300 Server
Viruses are inactive until the infected program is executed, or a boot record
is read. Thereafter, the virus loads itself into system memory and begins to
copy and spread itself. Diskettes used in a contaminated system can get
infected and, in turn, transfer the virus when used in another system. A
virus can also spread via programs downloaded from bulletin boards or the
Internet.
To Prevent Virus Infection
Obtain an anti-virus program and make it a habit to scan the
•
system regularly.
Make backup copies of all files and write-protect the disks.
•
Obtain all software from reputable sources and always scan new
•
software for any viruses prior to installing files.
If the system has been infected, find and remove the viruses using an
anti-virus program. Then turn off the system for a minimum of 15 seconds
to clear the virus from system RAM. You may want to rerun the anti-virus
software when you turn the system back on the verify that the system is
clean.
T r oubleshooting checklist
Before turning on the system, make sure that:
The power cord is connected to the AC power-in connector and an
•
AC outlet.
The AC outlet is supplying power.
•
If you use a power strip, you have turned it on, and set the circuit
•
breaker.
The voltage selection switch on the system power supply reflects
•
the proper voltage.
Troubleshooting 85
V erifyi ng your confi guration
If your system is not operating correctly, the BIOS may contain an invalid
configuration parameter. Enter the BIOS program and check your
configuration settings.
Trou bleshootin g guidelines
As you troubleshoot your system, keep the following guidelines in mind:
Never remove the system cover while the system is turned on.
•
Do not attempt to open the monitor; it is extremely dangerous.
•
Even if the monitor power is disconnected, stored energy within the
components can cause a painful or harmful shock.
If a peripheral such as the keyboard, mouse, drive, or printer does
•
not appear to work, verify that all connections are secure.
If the system displays an error message on the screen, write it
•
down word-for-word. You may be asked about it when calling
Technical Support.
Only qualified personnel should open the system for maintenance.
•
If you are qualified to maintain the system yourself, make certain
•
you are properly grounded before opening the system chassis. See
“Static electricity precautions” on page 2 for more information on
preventing electrostatic damage to the system.
