Upgrade
1.1 Overview
This procedure is to be used to install the 500-watt power supply upgrade to the
AlphaServer DS25 system. The old 375-watt power supplies are NOT
mechanically interchangeable with the new 500-watt units so therefore, they
will not fit into the system after this upgrade is complete. The upgrade kit part
number is 3X-H7911-UP and contains the following items:
• Three 30-10047-01 500-watt power supplies
• One 70-41154-01 500-watt PS backplane assembly
• Four 74-62829-01 tubular spacers
This procedure assumes that the system has been powered down and removed
from the rack or pedestal mounting, and that the system enclosure is laying on
its right side.
HINT. A 10-inch long #1 Phillips screwdriver is the recommended tool for
removing and installing the power supply backplanes. It is quite helpful if the
tip of the screwdriver is magnetized!
First the old power supplies and power supply backplane are removed and then
the new power supply backplane and 3, 500 watt power supplies are installed.
