Upgrade
1.1 Overview
This procedure is to be used to install the500-watt power supply upgradeto the
AlphaServer DS25 system. The old 375-watt power supplies areNOT
mechanically interchangeable with the new 500-watt units so therefore, they
will not fit into the system afterthis upgrade is complete. The upgrade kit part
numberis 3X-H7911-UP and contains the following items:
• Three 30-10047-01 500-watt power supplies
• One 70-41154-01 500-watt PSbackplaneassembly
• 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 andinstallingthepower supplybackplanes. 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.
