Note –
For additional troubleshooting information, see the
Sun Fire X2250 Server
Service Manual (
820-4593).
Server does not
power on when the
front panel Power
button is pressed.
Keep notes on the following situations in case you need to call Sun
service:
• Is the Power/OK LED illuminated on the front of the system?
(Ensure that the power cord is connected to the system and to a
grounded power receptacle.)
• Does the wall outlet have power? Test by plugging in another
device.
• Does the monitor sync within five minutes after power on? (The
green LED on the monitor stops flashing and remains illuminated.)
Keyboard or mouse
does not respond to
actions.
• 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 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
or
rlogin
.
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.
