System cannot read
the hard disk
information.
Do the following:
1. Turn off the server by pressing the Power button.
2. Remove the top cover.
3. Verify that the power and data cables are connected to the disk
drive and that the pins in the cable and connector are not bent.
4. Verify that the drives are cabled properly to the hard drive. See
Chapter 4 for information on hard drive cabling.
5. Replace the top cover.
6. Turn on the server.
System cannot read
the CD information.
Check the following:
• Are you using the correct type of CD?
• Is the CD properly inserted into the drive?
• Is the CD clean and unscratched?
• Are the cables connected to the DVD-ROM drive?
Keyboard or mouse
does not respond to
action.
• Verify that the mouse and keyboard cables are connected to the
on-board USB 2.0 connectors on the server.
• Verify that the server is powered on and that the front Power/OK
LED is illuminated.
Server appears to be
in low power mode,
but the Power/OK
LED does not blink.
The Power/OK LED only blinks when all server components are in
low power mode. A tape drive might be connected to your server.
Because tape drives do not enter low power mode, the Power/OK
LED does not blink.
Server is hung or
frozen: No response
from mouse or
keyboard or any
application.
Try to access your system from a different server on the network:
1. On another system, type ping IP_address_of_X2250
2. If a response is returned, then try logging in to the Sun Fire X2250
server using either telnet, ssh,orrlogin.
3. If you successfully log in, list the running processes using the ps
command.
4. Kill any processes that appear unresponsive or should not be
running, by using the kill process_ID command.
5. Check the responsiveness of the Sun Fire X2250 server after each
process is killed.
If the above procedure does not work, power cycle the server:
1. Press the Power button to power off the server and wait 20 to 30
seconds.
2. Press the Power button again to power on the system.
