HP DL760 ProLiant DL760 Generation 2 Server Maintenance and Service Guide - Page 110

Connectors, Switches, and LED Indicators System Interconnect LED Indicators To prevent damage to critical system components, the ProLiant DL760 G2 server will not power up if it detects that certain components are not installed or are installed incorrectly. The system interconnect LEDs provided with ProLiant DL760 G2 servers provide a closed-loop checking mechanism for verifying proper component mating and interconnections between critical server components. LEDs inside the sliding top cover provide visual assistance in isolating components to check if the server will not power up due to a component or module that is not fully installed. If a status indicator light is on, reseat the component represented by the indicator. Refer to the hood labels for component location. IMPORTANT: To check system interconnect status LEDs, place the server in Standby with the power supplies plugged in.
