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.
When the services gateway is powered by standard-capacity AC power supplies, the services gateway
contains either three or four AC power supplies, located at the rear of the chassis in slots PEM0 through
PEM3 (left to right). Each 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
power supplies provide full power redundancy. If one power supply fails or is removed, the remaining
power supplies instantly assume the entire electrical load without interruption. Three power supplies
provide the maximum configuration with full power for as long as the services gateway is operational.
When the services gateway is powered by either standard- or high-capacity DC power supplies, or by
high-capacity AC power supplies, power distribution within the chassis is divided into zones, as described
in
.
