Installing or Replacing an ERA/O Card 1-1
This document explains how to install and remove your system’s Embedded Remote Access
Option (ERA/O) card.
Before You Begin
NOTE: For more information about setting up and using an ERA/O card, see the
remote access controller (RAC) documentation provided on the documentation CD that
came with your system or on the Dell Support website at support.dell.com.
NOTE: The Dell™ Remote Access Card III (DRAC III), DRAC III/XT, Embedded
Remote Access (ERA), and the ERA/O are systems management hardware and
software solutions designed to provide remote management capabilities for
PowerEdge™ systems. Collectively, these solutions are known as remote access
controllers (RACs). RACs allow you to remotely manage and monitor your system even
when the system is down.
Before installing the ERA/O card, record the system configuration settings. View the system
configuration screens in the System Setup program and make a note of each setting. See
your User's Guide for instructions about using the System Setup program.
Installing an ERA/O Card
CAUTION: Only trained service technicians are authorized to remove the system
cover and access any of the components inside the system. See your System
Information Guide for complete information about safety precautions, working
inside the computer, and protecting against electrostatic discharge.
1Remove the optional front bezel (if applicable).
2Turn off the system, including attached peripherals, and disconnect the system and
peripherals from their electrical outlets.
3Remove the optional security screw (if applicable). See Figure 1-1.
4Press the latch on the system front panel and lift the left cover.
5Lift the right cover.

10 If you removed a ROMB backup battery in step 7, replace the battery. See Figure 1-3;
also see "Installing a ROMB Card" in your Installation and Troubleshooting Guide.
11 Replace the SCSI backplane. See Figure 1-2.
aFit the metal tabs at each end of the backplane into the slots in the chassis wall,
and lower the backplane into the chassis, ensuring that the CD and diskette drive
interface cables are not caught under the backplane.
bPress down firmly over the handle to seat the backplane in its connector.
cPivot the release latch out into the securing slot in the chassis.
dConnect the CD drive interface cable to the CD_ROM connector on the
backplane board.
eConnect the diskette-drive interface cable to the FLOPPY connector on the
backplane board.
fPress all installed hard drives firmly back into the SCSI connectors on the
backplane.
12 Close the system covers.
When closing the covers, close the right (larger) cover first and then close the left
cover. Press firmly on the left cover to snap the securing latch into place.

before, you must remove the thin plastic cover that protects the connector.
You can insert your finger underneath the silver strip at the top of the cover to tear
away the cover. See Figure 1-5 for the location of the connector.
17 Connect a network cable to the RAC Ethernet connector. See Figure 1-5.
