ISS3124-RP2 Server Power Supply LEDs
There is a single bi-color LED (green/amber) to indicate the ISS3124-RP2 server power supply
status. Table 5-3 describes the different states of the LED.
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 “No Video After Power-On” on
page 48 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.
