Step 5. Remove the adapters and disconnect the cables and power cords to all internal and external
devices until the server is at the minimum configuration that is required for the server to start (see
"Power-supply LEDs" on page 55 for the minimum configuration).
Step 6. Reconnect all power cords and turn on the server. If the server starts successfully, reseat the
adapters and devices one at a time until the problem is isolated.
If the server does not start from the minimum configuration, see "Power-supply LEDs" on page 55 to replace
the components in the minimum configuration one at a time until the problem is isolated.
