    Chapter 1 Preparation for Cabling the HP NetServer LXr8500 If you install several HP NetServers on one circuit, however, precautions are necessary. For instance, 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, they may trip and thus prevent the servers from powering up.
