No Video After Power-On
If the power is on and the system has had adequate time to boot, but there is no video, check all
add-on cards and cables. Tighten or re-plug any loose cable connections. Be sure your monitor is
powered up and switched to the
On position.
Use the speaker to determine if any beep codes exist. Refer to Appendix A, “BIOS Error Codes”
for details.
If video output is still absent, check with your system administrator or service provider.
Loss of System Setup Configuration
Make sure that your power supplies are operating properly, see “ISS3112-RP2 Server Power
Supply LEDs” on page 74 for guidelines. An improperly operating power supply may cause the
system to lose the CMOS setup information. If this does not fix the Setup Configuration problem,
consult your system administrator or contact your service organization for repairs.
Safe Power-Off
There are several safe power-off methods for a NAS Server or JBOD. They include:
• Using the OS GUI power-off button at the console screen, if a keyboard/mouse/video
monitor is connected.
• Pushing and holding the Power button on the front panel.
