Connectors, LEDs, and Switches
Interlock Status
Improperly seated components in the interlock chain cause the LED associated with the fault
origination point to illuminate on the system board. Figure 4-7 and Table 4-7 identify the
location and status of each of the LEDs.
NOTE: Interlock components are required for the system to power up.
IMPORTANT: ProLiant DL580 Generation 2 servers are not equipped with chassis door or access
panel interlocks.
