About Your System
23
A non-redundant power supply has an LED indicator that shows whether
power is present or whether a power fault has occurred.
• Not lit — AC power is not connected. It also indicates that the system
is in standby mode.
• Green — When the system is on, a green light also indicates that the
power supply is providing DC power to the system.
Figure 1-5. Non-Redundant Power Supply Status Indicator
Diagnostic Lights (Optional)
The four diagnostic indicator lights on the system front panel display error
codes during system startup. Table 1-1 lists the causes and possible corrective
actions associated with these codes. A highlighted circle indicates the
light is on; a non-highlighted circle indicates the light is off.
NOTE:
The diagnostic LEDs are not present when the system is equipped with
an LCD display.
