components are hot-swappable or cold-swappable, and whether they can be
removed from the front of the system or through the top of the system.
Front Panel LEDs
Several front panel LEDs provide general enclosure status, alert you to system
problems, and help you to determine the location of system faults.
During system startup, the LEDs are toggled on and off to verify that each one is
working correctly. LEDs located on the front panel work in conjunction with specific
fault LEDs. For example, a fault in the power supply subsystem illuminates the
power supply Service Required LED on the affected power supply, as well as the
system Service Required LED. Since all front panel status LEDs are powered by the
system’s standby power source, fault LEDs remain lit for any fault condition that
results in a system shutdown.
