About Cautions
CAUTION:
A CAUTION indicates a potential for property damage, personal injury, or death.
Dell™ PowerEdge™ 850 Systems
Information Update
IDE Device Functionality
When a Dell Remote Access Controller 4 (DRAC 4) is used with any version of Red Hat
Linux, the system may lose functionality of IDE devices. To avoid this, pass the following parameter
to the kernel command line at system boot:
linux ide2=0x1f0
Using this kernel command allows the operating system to access the internal CD-ROM drive as well
as the virtual CD-ROM on the DRAC 4 system.
Fan Assembly
In order to replace a PCI fan module, follow the procedures in this section instead of the steps described
under "Fan Assembly" in your Installation and Troubleshooting Guide.
NOTE:
The PCI fan module is required only for certain expansion card options and allowed only for certain chassis
configurations. Otherwise, the system fan assembly provides adequate cooling, and the PCI fan module is not
installed.
Removing the PCI Fan Module
CAUTION:
Any installation that requires removal of the system cover is intended solely to be performed
by trained service technicians. See your Product Information Guide for complete information about safety
precautions, working inside the computer and protecting against electrostatic discharge.
1 Open the system. See "Opening the System" in the Installation and Troubleshooting Guide.
2 Disconnect the fan module's power cable from the connector on the system fan assembly.
3 Disconnect the chassis intrusion switch cable from the INTRUSION_SWITCH connector on
the system board.
4 Gently pull the cables connected to the daughter card out of the slot on the mounting bracket.
5 Remove the two screws connecting the mounting bracket to the chassis and remove the PCI fan
module from the system. See Figure 1.
