• 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

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

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.
