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.

Working Inside the Extended Memory Blade Server

This section describes how to perform the following tasks within a extended memory blade server. All

of these procedures require you to first remove the server from the chassis, and then remove the cover.
