Chapter 2
Unpacking and Setting up the 150U
This chapter outlines how to unpack and set up your new Sun Model 150U and some of its peri-
pherals (subsystems are covered in the chapter Sub'lIdem Set-up).
If you are
upgrading your Sun Model 150 rather than starting with a system 'fresh from the
box,' please heed the warning on the front page of this manual. Sun-l systems which are
upgrading must not attempt to install this release of the system until all Multibus memory has
been removed or disabled, and - for an upgrade from a Xylogics 440 to a Xylogics 450 -
cabling has been re-routed. Disk switch settings may also need to be reset. Make sure you have
followed the procedures given in Sun's Upgrade Indallation Guide before proceeding.
If you are adding boards and/or peripherals to an existing system, the chapter on
Hardware
Configuration and Ezpan,ion will give you the information you need.
