See the Dell Remote Access Controller/Modular Chassis Version 1.1 User's Guide at support.dell.com for more information about firmware updates and installing redundant DRAC/MC modules. This guide also provides complete instructions on how to set up and operate that version of the module.

Guidelines for Installing Connectivity Modules

When inserting connectivity modules into the system’s back-panel I/O bays, follow these guidelines:

NOTE: See your Installation and Troubleshooting Guide for the I/O-bay numbering sequence.

Insert a connectivity module into I/O bay 1 before installing a connectivity module into I/O bay 2.

I/O bays 1 and 2 support only Gb Ethernet switch or pass-through modules. Ensure that the Ethernet modules installed in I/O bays 1 and 2 are of the same type.

Insert a connectivity module into I/O bay 3 before installing a connectivity module into I/O bay 4.

Ensure that the connectivity modules installed in I/O bays 3 and 4 are of the same type.

For more information, see the Dell Remote Access Controller/Modular Chassis Version 1.1 User's Guide at support.dell.com.

Red Hat Enterprise Linux (Version 3) Update 3 Operating System Information

Installation

Newer Intel® processors have an XD bit-enabled feature that allows an operating system to reserve a segment of memory to store code in a non-executable environment. Under certain circumstances, this feature can cause the installation of the Red Hat Enterprise Linux (version 3) Update 3 operating system from the Dell OpenManage CD to fail.

To disable XD-bit support to prevent this installation failure, add switch noexec=off to the /etc/grub.conf file as shown in the following example:

kernel /vmlinuz-2.4.21-20.EL ro root=LABEL=/ noexec=off

If an EM64T kernel is being used, also include the noexec32=off parameter on the kernel line as shown in the following example:

kernel /vmlinuz-2.4.21-20.EL ro root=LABEL=/ noexec=off noexec32=off
