System Interconnect Status Indicators
To prevent damage to critical system components, the ProLiant DL740 server will
not power up if the server detects that certain components are not installed or are
installed incorrectly. The ProLiant DL740 server comes equipped with system
interconnect indicators that provide a closed-loop checking mechanism for verifying
proper component mating and interconnections between critical server components.
LEDs on the front of the server provide visual assistance with isolating components
that may be preventing the server from powering up. If a status indicator light is on,
reseat the component represented by the indicator. Refer to Appendix D for detailed
LED descriptions. Refer to the hood labels for component location.
IMPORTANT: To check system interconnect status indicator LEDs, place the server in
Standby with the power supplies plugged in.
