Information Update 3
Information Update
Installing an Internal USB Memory Key
The USB memory key can be used as a boot device, security key, or mass
storage device. To use the internal USB connector, the Internal USB Port
option must be enabled in the Integrated Devices screen of the System Setup
program.
To boot from the USB memory key, you must configure the USB memory
key with a boot image and then specify the USB memory key in the boot
sequence in the System Setup program. See "Integrated Devices Screen"
in your Hardware Owner’s Manual . For information on creating a bootable file
on the USB memory key, see the user documentation that accompanied
the USB memory key.
WARNING: Many repairs may only be done by a certified service technician.
You should only perform troubleshooting and simple repairs as authorized in
your product documentation, or as directed by the online or telephone service
and support team.
NOTE: To avoid interference with other components, the maximum allowable
dimensions of the USB key are 24 mm (0.94 in) wide x 79 mm (3.11 in) long x 8.6 mm
(0.33 in) high.
1 Turn off the system, including any attached peripherals, and disconnect
the system from the electrical outlet.
2 Open the system. See "Removing and Installing the Top Cover"
in your
Hardware Owner’s Manual .
3 Locate the USB connector on the system board. See Figure 6-1
in your
Hardware Owner’s Manual .
4 Insert the USB memory key into the USB connector.
5 Close the system. See "Removing and Installing the Top Cover"
in your
Hardware Owner’s Manual .
6 Reconnect the system to power and restart the system.

Added Support for 8-GB Memory Modules
Your Dell™ PowerEdge™ R900 system now supports the following 8-GB
memory configurations:
• 32 GB — 4 x 8-GB quad-rank memory modules
• 64 GB — 8 x 8-GB quad-rank memory modules
NOTE: If 64 GB of memory is installed, the system will only recognize
and display 63.75 GB during POST.
• 128 GB — 16 x 8-GB quad-rank memory modules
• 256 GB — 32 x 8-GB quad-rank memory modules
NOTE: Prior to upgrading your system, verify that the latest system BIOS version is
on your system. Loading the latest BIOS version from support.dell.com will ensure
that your system is fully supported.
NOTE: Some operating systems cannot support more than 4 GB of physical
memory. For more information on memory support requirements and restrictions,
refer to the operating system documentation that ships with your system.

Information Update 5
BMC and DRAC5 Firmware Version Requirements
When upgrading either the BMC or the DRAC5, you must update the
firmware for both components to ensure full functionality and compatibility.
For example, the power reduction feature of the DRAC5 version 1.40
firmware works only when BMC 2.27 or higher is also installed. If the BMC
and DRAC firmware are incompatible—BMC 2.27 installed with DRAC5
version 1.33 or BMC 1.79 installed with DRAC5 version 1.40—the power
reduction feature may not function correctly.
Back Cooling Fans
Systems manufactured after September 2008 no longer include the four back
cooling fans installed in earlier systems. Therefore, BMC version 2.27 does
not recognize the presence of back fans. The back fans will still run in older
systems; however, from a system perspective, the fans do not exist and are
not monitored. As a result, if the back fans fail, the SEL, server management
software, and remote access card will not log the error. This change does not
compromise the standard hot plug and redundancy features of the front fans.
New LCD Error Codes
The following LCD error codes have been added for your system. For a
complete list of error codes, see "About Your System" in your Hardware
Owner’s Manual.

New SEL Sensor Messages
The following SEL sensor messages have been added to the systems
management software and remote access card software.
System Board Replacement - Safeguarding
Encrypted Data
On systems using an operating system that supports the Trusted Platform
Module (TPM) and related encryption programs, you can use these features
to secure the contents of the hard drive(s).
If you are using the TPM with an encryption program, you may be prompted
to create a recovery key during system or program setup. Be sure to create and
safely store this recovery key. If you ever need to replace the system board, you
must supply the recovery key when you restart your system or program, before
you can access the encrypted data on your hard drive(s).
