HP D2D, User Manual

Page: 182 / 210

Power On/Off Problems
The normal boot sequence takes approximately 2 minutes. On power up the HP D2D Backup System
runs its fans at high speed for approximately 10 seconds before returning to normal speed. When
powering off the HP D2D Backup System make sure no backup or restore jobs are running or scheduled
to run while the HP D2D Backup System is out of action.
HP D2D shuts down automatically
The HP D2D has found a problem with the internal hardware which requires the device to shutdown
to avoid further hardware problems. The System Health LED on the front panel will probably be
flashing RED.
• Plug in a monitor and keyboard directly to the back of the HP D2D (see
“
To connect a system console ” on page 56) and watch for errors on boot up or on the Console
screen.
• If iLO100 is available on your system, check for errors in the event log.
HP D2D does not boot up correctly
Check the Power LED on the front panel.
If the Power LED is OFF:
• Check power is connected to the HP D2D and is on.
• The PSU may be faulty.
If the Power LED is AMBER:
• Power on the HP D2D using the Power button.
• If it shuts down again, see “ HP D2D shuts down automatically ” on page 182.
If the Power LED is GREEN:
• Plug in a monitor and keyboard directly to the back of the HP D2D (see
“
To connect a system console ” on page 56) and watch for errors on boot up or on the System
Console screen.
• If all the LEDs turn on except for the hard disk drive LEDs, the SmartArray RAID controller in one
of the PCIe slots may be at fault. On the System Console screen, the Smart Array status normally
shown at boot time will not display. No hard disk drive LEDs will turn on. Please refer to SmartArray
RAID information on
http://www.hp.com/support .
• If the System Console screen is not seen:
• The HP D2D operating system may not be seen or recognized. Check the flash memory module
inside the HP D2D for correct seating. (To locate the flash memory module, refer to the
schematic on the hood label.)
• Check for hardware errors as the HP D2D device boots up.
HP D2D System Health LED is flashing RED
One of the two power supplies is not connected to power at power on time, causing a warning
condition. Ensure both power supplies are connected and reboot to clear this LED. The HP D2D will
work satisfactorily with one power supply, but without any redundancy. It is recommended to power
on the second power supply or replace the power supply as soon as possible.
