Cisco UCS B440 High Performance Blade Server Installation and Service Note
OL-22475-01
topicWorking Inside the Blade Server
LED states are saved, and if you remove the blade from the chassis the LED values will persist for up to
10 minutes. Pressing the LED diagnostics button on the motherboard will cause the LEDs that currently
show a component fault to light for up to 30 seconds for easier component identification. LED fault
values are reset when the blade is reinserted into the chassis and booted, and the process begins from its
start.
If DIMM insertion errors are detected, they may cause the blade discovery to fail and errors will be
reported in the server POST information, viewable using the UCS Manager GUI or CLI. UCS blade
servers require specific rules to be followed when populating DIMMs in a blade server, and the rules
depend on the blade server model. Refer to the documentation for a specific blade server for those rules.
HDD status LEDs are on the front face of the HDD. Faults on the CPU, DIMMs, or adapter cards will
also cause the server health LED to light solid Amber for minor error conditions or blinking Amber for
critical error conditions.
