Power Distribution System

Your rack might have the Sun Rack 900 Power Distribution System option installed. Refer to
Figure 1-4. The Power Distribution System consists of four inputs (two sets of two:
AC_Grid_0 and AC_Grid_1), two power sequencers (A and B), two power strips, and
connecting cables.
FIGURE 1-4
Each power input to the rack should be connected to a dedicated 20 Amp (North America) or
16 AMP (International) branch circuit. Individual outlets are grouped into sets of four. Each
individual outlet has a maximum current rating of 10 Amps. However, each outlet group has
a maximum current rating of 10 Amps also. In other words, the total current for a group of
four outlets cannot exceed 10 Amps.
Note –
AC power source.
