Conventions Used In This Guide
This document uses the following conventions:
Convention Description
Return A key name is shown enclosed to indicate that you
press the named key on the keyboard.
UPPERCASE
lowercase
The console program does not distinguish between
uppercase and lowercase characters in typed user
input. All examples in this guide show user input
in lowercase. All system output is in uppercase.
show A word in this typeface indicates a command that
you must enter from the keyboard at the console
prompt
(>>>) . For example, boot .
Note
There is an 80-character
limit on the input line.
Commands cannot be wrapped
or continued to a new line.
Use the abbreviated form
of a command so the whole
command can be entered on
one line.
Because of space restrictions in
this guide, command format
examples show commands
continued to a new line.
variable Lowercase italicized letters in commands indicate
a variable value that you must provide. The value
must be an actual option like a number or logical
such as on/off. Example:
>>> set language 3
[ ] The information contained within these brackets
is optional. The brackets are not part of the
command syntax and should not be typed.
{ } The information contained within these braces is
required. The braces are not part of the command
syntax and should not be typed.
xi

Convention Description
" " Quotation marks indicate a literal string. A
command in lowercase surrounded by quotes will
not convert to uppercase and will be put on the
network as lowercase. For example,
>>> B esa0
-fi "test.sys" will remain in lowercase
letters.
- Options/qualifiers are identified by a hyphen. The
hyphen indicates that additional information can
be, or in some cases must be, supplied on the
command line. The hyphen must be typed.
Note Notes provide general information.
WARNING: Warnings contain information to prevent personal
injury. Read these carefully.
CAUTION: Cautions provide information to prevent damage
to equipment or software. Read these carefully.

Removing System Components
To remove a TURBOchannel option, disconnect the
power cord and the option.
To remove the CPU, a memory module, or the power
supply, disconnect the power cable and the module.
Before you replace the system module, remember to
swap the Ethernet ROM, that is, move the chip from
the failing system module to the replacement system
module. Detailed instructions for locating, removing
and replacing the Ethernet ROM are available in the
DEC 3000 Model 300 Series AXP Hardware Reference
Guide, part number EK–PELCN–OG.

Removing System Components
Figure 1–1 shows a 3-dimensional view of the
components in a DEC 3000 Model 300 Series
AXP system. To remove the system module in a
DEC 3000 Model 300 Series AXP system, disconnect
and remove each of the components (see Figure 1–1)
in the following order:
! Power harness
" SCSI cable
# Removable-media device (or hard disk drive)
$ Hard disk drive
% Memory
& CPU module
' TURBOchannel option slot filler panels
( Power supply
) System module
+> Loose metal plate
+? Bottom system enclosure
To remove a removable-media device # or a fixed
disk drive $ , disconnect the power cord and SCSI
cable and then the device.
Refer to the DEC 3000 Model 300 Series
AXP Hardware Reference Guide, part number
EK–PELCN–OG, for detailed component installation
and removal instructions.
