BIOS errors and warnings
The BIOS generates warnings/errors on invalid memory configurations:
●
If the BIOS can find a valid memory configuration by disabling plugged-in memory, it does so and
reports a warning during POST. The system can still be booted. The warning will indicate the
location of the failed DIMM on the system board or memory riser.
●
If there is no way for the BIOS to obtain a valid memory configuration by disabling plugged-in
memory, the BIOS halts with a diagnostics 2006 code for memory error (five beeps and blinks).
System board memory
This section presents system board memory information, including removal and installation procedures.
Removing a memory module
This section describes how to remove a system board memory module.
1. Disconnect power from the system (see
Predisassembly procedures on page 52).
2. Remove the side access panel (see
Removing the side access panel on page 57).
CAUTION: To ensure that memory modules are not damaged during removal or installation,
power off the workstation and unplug the power cord from the AC power outlet. If you do not unplug
the power cord before installing memory, the modules might be damaged and the system will not
recognize the memory changes.
3. Press the green tab at the base of the memory fan (1) and lift it up to expose the memory modules
(2) as shown in the following figure.
