SRPL8 Server System Product Guide 159
Power Light Does Not Light
Check the following:
• Are all the power supplies plugged in? Is the power turned on to the outlet? Is there a blown
fuse or breaker?
• Is the system connected to a 208 VAC source?
• Is the system operating normally? If so, the power LED is probably defective or the cable
from the front panel to the I/O carrier is loose.
• Are there other problems with the system? If so, check the items listed under “System Cooling
Fans Do Not Rotate Properly” on page 160.
• If all items are correct and problems persist, contact your service representative or authorized
dealer for assistance.
No Beep Codes
If the system operates normally, but there was no beep, the speaker might be defective. If the
speaker is enabled, but the speaker does not function, contact your service representative or
authorized dealer for assistance.
Record the beep code emitted by POST, and see “Error and Informational Messages” on page 162.
No Characters Appear on Screen
Check the following:
• Is the keyboard working? Check to see that the “Num Lock” light is functioning.
• Is the video monitor plugged in and turned on? Many modern video monitors shut down when
inactive and may require a moment to warm up when activated.
• Are the brightness and contrast controls on the video monitor properly adjusted?
• Are the video monitor switch settings correct?
• Is the video monitor signal cable properly installed?
• Is the onboard video controller enabled?
• If you are using an add-in video controller board, do the following:
1. Verify that the video controller board is fully seated in the I/O carrier connector (and verify
that the video monitor is plugged in to the ACTIVE video controller).
2. Reboot the system for changes to take effect.
3. If there are still no characters on the screen after rebooting the system and POST emits a beep
code, write down the beep code you hear. This information is useful for your service
representative. See “POST Codes and Countdown Codes” on page 163.
4. If you do not receive a beep code and characters do not appear, the video display monitor or
video controller may have failed. You can verify this by trying the monitor on another system
or trying a different monitor on this system. Contact your service representative or authorized
dealer for assistance.
