Connecting AC Power to Multiple-Server Configurations
The HP Server temporarily draws a large "inrush current," when first connected to an AC power
source. This also occurs when the Server is in a standby mode (power is turned off, but the power
cord is plugged into AC power). The inrush current is much greater than the Server's normal operating
current and generally, the AC power source can handle the normal inrush current.
However, if you install several HP Servers on one circuit, precautions are necessary. If there is a
power failure and power is then restored, all the servers immediately begin to draw inrush current at
the same time. If the circuit breakers on the incoming power line have insufficient capability, the
breaker may trip and thus prevent the servers from powering up.
