In all power supply configurations, the power distribution is shared. All of the power supply
power to all of the components in the services gateway chassis. The power supplies are
guaranteed to provide adequate power to the system. In the low-line (110VAC input) and
high-line (220VAC input) configurations, two power supplies are required to support the
services gateway electrical requirements. Although the services gateway is configurable
with three (2+1) power supplies, you can add a fourth power supply for fault tolerance.
The fourth power supply is used when one of the power supplies in the 2+1 configuration
fails.
NOTE:
There are no slot restrictions for AC power supplies. If you are using
two DC power supplies, then use any of the slot combinations as shown in
