16.5.2 The power-on indicator reports an error by
flashing continuously
It is no longer possible to establish a Remote Desktop connection or access any
service or file on the Headless server. Additionally the power-on indicator
reports an error by flashing continuously.
There are two different error states indicated by the power-on indicator:
The power-on indicator flashes at a high frequency (2 Hz, twice every
second).
This error state indicates that an error occurred during the early BIOS POST
phase. The system is unable to finish the BIOS POST phase successfully due
to an error involving the system board. Additionally a beep code might be
audible. A typical error cause might be an improperly seated memory module.
In order to resolve such problems, proceed as follows:
Ê Terminate all applications and shut down the server.
I If the server does not shut down properly, press and hold the On/Off
button for five seconds, until the server switches off.
Ê Disconnect the AC power cord from the system.
Ê Unlatch and remove the side cover as described in section "Removing the
side cover" on page 43.
Ê Ensure that all memory modules and expansion cards are properly seated
in the slots.
Ê Ensure that all cables are connected correctly.
Ê Close the side cover and lock it in place as described in section "Installing
the side cover" on page 56.
Ê Reconnect the AC power cord.
