HP server ML350 G3 won't boot, red internal health LED

http://community.spiceworks.com/how_to/show/2931-reset-hp-ilo-2-password-without-server-reboot

Can you confirm that server fan is rotating or not when server power on. and which led glowing red when you power on server

you can tray to refix system ram on server and check it

You will continue to get internal error until you add memory. It shouldn't even boot without RAM.

Open the case and turn it on. There should be corresponding red light indicator inside or possibly the back.

Check with another PPM module.
clear NVRAM.

check your smps and the raid status if you have created any raid in the server....

If it is not booting at all then the disks will not be configured. Better boot the server using the HP utility CD and install the OS after creating the right array and partitions.

The ProLiant DL380 G3 server requires that both primary and redundant fans exist in a specific configuration in order to perform optimally. Any deviation from the specified configuration will cause one of the above error messages to occur and the internal Health LED to illuminate. In a ProLiant DL380 G3 server without the redundant fan option, the server will shut down after the error message is displayed. In a server with the redundant fan option, the internal Health LED will illuminate and the appropriate error message regarding fan redundancy will be displayed. The purpose of this document is to detail the required configuration for both primary and redundant fans.
DETAILS Both primary and redundant fans in the ProLiant DL380 G3 server must be configured to meet specific requirements in order to avoid the error messages above and in some instances, subsequent shutdown of the server.
All primary fan locations (2, 4, 5, 6 and 7) must be populated with a fan before the redundant fan locations (1, 3, or 8) are populated. If a primary fan location is left unpopulated, the server will display one or more of the error messages shown above. In addition, the internal Health LED (the top LED on the front panel of the server) will display the status of the fans.
When the redundant fan option is used, all redundant fan locations must be populated. ProLiant servers do not support partial population of redundant fans. If any redundant fan location is populated without also populating all other redundant fan locations in the server, the fan system will not be fully redundant and one or more of the error messages above will be displayed.
Figure 1 below illustrates a ProLiant DL380 G3 server configured with all eight fans installed for fan redundancy. The server airflow is divided into three zones: processor, I/O and power supply. Shared fans 4 and 7 each provide airflow for two zones. If a shared fan fails, the failure is experienced in both zones.

The internal Health LED (the top LED on the front panel of the server) indicates failed or missing components. The internal Health LED should be observed to determine the status of the fans as follows:
RED LED: A red LED indicates that the minimum fan requirements have not been met. Minimum fan requirements indicate that all primary fan slots must be populated with functioning fans.

• If the 1611 fan "x" is not present (where "x" is the fan location) error message is displayed at POST and the internal Health LED is red , then a primary fan is missing.
  
  
• If the 1611 fan "x" failure (where "x" is the fan location) error message is displayed at POST and the internal Health LED is red , then a primary fan has failed.

AMBER LED: An amber LED indicates that the minimum fan requirements have been met; however, requirements for redundant fan configuration have not been met. This means that all primary fan slots are populated with functioning fans, but at least one redundant fan has either failed or is missing.

• If the 1611 fan "x" is not present (where "x" is the fan location) error message is displayed at POST and the internal Health LED is amber , then a redundant fan is missing.
  
  
• If the 1611 fan "x" failure (where "x" is the fan location) error message is displayed at POST and the internal Health LED is amber , then a redundant fan has failed.
  

Note: In a redundant fan configuration, the error message fan system not fully redundant will also be displayed at POST if any redundant fan slot is left unpopulated or if a redundant fan has failed.

Hi Franceso, plz specify
Is it powering ON ?
Which LED is glowing?
These leds are there on the front panel :

1 Power On/Standby button
2 System power LED
Green = Power on
Amber = System shut down, but power still applied
Off = No power

3 Internal health LED (Wave sign in BOX)
Green = Normal
Amber = System degraded. To identify the component in a degraded state, refer to system board LEDs.
Red = System critical. To identify the component in a critical state, refer to system board LEDs.
Off = Normal (when in standby mode)

4 External health LED (power supply)
Green = Normal
Amber = Power redundancy failure
Red = Critical power supply failure
5 NIC 1 activity LED Green = Network link
Flashing = Network link and activity
Off = No link to network.
6 UID LED Blue = Activated
Flashing = System remotely managed
Off = Deactivated
7 UID button

If it is Internal health led then any internal h/w issue is suspected.
If it is external health led then any power supply or power source related issue is suspected.
Also check the status of the server & its IML (Integrated Management Logs) in ilo (Integrated Lights Out ) if it is configured. (2nd RJ45 port in rear)

Also make sure the cabinet is properly closed.
