IBM 8265: Planning and Site Preparation Guide
Determining the Number of Power Supplies Required
The number of power supplies required to operate the 8265 and all installed modules
is determined by adding together:
•
The system overhead, the power required by the 8265 to operate the fans and
backplane, which is 1 Watt at +5.2 volts.
•
The total power requirement (at +5.2 volts) of all installed modules (and daughter
cards).
When you have calculated the total power required, you can determine how many
power supplies are needed (see page 14).
If power fault-tolerance is required, then at least one additional power supply should
be installed.
Module Power Requirements
Table 12 lists the power requirements for the 8265 modules and daughter cards.
