After removing a hard drive in a hot-pluggable environment, wait at least 30 seconds prior to installing the new hard drive.

COM1 Port Conflict After Installing the Microsoft Windows 2000 SP4 or Windows Server 2003 Operating System

If the Microsoft Windows 2000 SP4 or Windows Server 2003 operating system is installed and console redirection is enabled, a yellow exclamation mark conflict will appear by COM1 in the Device Manager. This is because the operating system attempts to assign a COM1, but the server module physically does not have a serial port. To prevent the conflict from returning, delete the COM1 port in Device Manager.

Shutdown Procedure for Servicing a Hard Drive

NOTE: This section applies only to situations where the server module must be powered down to service a hard drive. In many situations, the hard drive can be serviced while the server module powered on.

If you need to power off the server module to service a hard drive, wait 30 seconds after the server module’s power indicator turns off before removing the hard drive. Otherwise, the hard drive may not be recognized by the PERC 4/IM after the hard drive is reinstalled and the server module is powered on again.

Acquiring the asset.com Utility

The asset.com utility is not located in the Service Mode section of the Dell OpenManage Server Assistant CD. To acquire the utility, use the Server Assistant CD to create a bootable diskette and the utility is created on that diskette. The asset.com utility will be available in the Service Mode section in future releases of the Server Assistant CD.

Red Hat Enterprise Linux AS (Version 3) Operating System Diskette Drive Detection Messages

When the Red Hat Enterprise Linux AS (version 3) operating system boots, it detects the USB controller and attempts to load a USB diskette drive. If the optional USB diskette drive is not connected to the server module’s front-panel custom cable, the operating system attempts to load the diskette drive five times and displays informative messages on the screen. After five attempts with no USB diskette drive detected, the messages stop appearing. If a USB device is removed or inserted, the detection attempts begin again. This is a normal operating system behavior.
