The services gateway uses either AC or DC power supplies. The services gateway is
configurable with two, three, or four AC power supplies or two or four DC power supplies.
The power supplies connect to the midplane, which distributes the different output
voltages produced by the power supplies to the services gateway components, depending
on their voltage requirements. Each power supply is cooled by its own internal cooling
system.
CAUTION: The services gateway cannot be powered from AC and DC power
supplies simultaneously. The first type of power supply detected by the
services gateway when initially powered on determines the type of power
supply allowed by the services gateway. All installed power supplies of the
other type are disabled by the services gateway. If you install a power supply
of the other type while the services gateway is operating, the services gateway
disables the power supply and generates an alarm.
Redundant power supplies are hot-removable and hot-insertable. When you remove a
power supply from a services gateway that uses a nonredundant power supply
configuration, the services gateway may shut down depending on your configuration.

The services gateway supports either the low-line (110V) AC power configuration or the
high-line (220V) AC power configuration.
In the low-line (110 V) AC power configuration, the services gateway contains three or
four AC power supplies, located horizontally at the rear of the chassis in slots
through (left to right). Each AC power supply provides power to all components

in the services gateway. When three power supplies are present, they share power
almost equally within a fully populated system. Four AC power supplies provide full
power redundancy. If one power supply fails or is removed, the remaining power supplies
