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.

1 Remove the optional front bezel (if applicable).
2 Turn off the system, including attached peripherals, and disconnect the system and peripherals from their electrical outlets.
3 Remove the optional security screw (if applicable). See Figure 1-1.
4 Press the latch on the system front panel and lift the left cover.
5 Lift the right cover.

6 Remove the SCSI backplane board:

a Pull each hard-drive carrier partially out of its slot, approximately 2.5 cm (1 inch).
b Disconnect the diskette-drive interface cable from the FLOPPY connector on the backplane board. See Figure 1-2.
c Disconnect the CD drive interface cable from the CD_ROM connector on the backplane board. See Figure 1-2.
d Press the release latch in toward the backplane board and use the handle to pull the board out of its connector and up out of the chassis. See Figure 1-2.

7 If the system has an optional ROMB card installed, remove the ROMB backup battery (not the ROMB card itself) to expose the ERA/O card connector.

See Figure 1-3; see also "Removing a ROMB Card" in your Installation and Troubleshooting Guide.

8 Unpack the ERA/O card.

If you are replacing an ERA/O card, see "Removing an ERA/O Card" for removal instructions before continuing with the next step.

9 Install the ERA/O card in the ERA/O card connector (EMBEDDED_REMOTE_ASSISTANT) on the system board. See Figure 1-4.

a Align the connector on the bottom of the ERA/O card with the ERA/O connector on the system board; align the holes along the edges of the card with the center posts of the four retention clips on the system board.
b Press the card down into the connector and onto the retention clip posts until the clips snap into place around the card and the card is fully seated into the connector.

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.

a Fit 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.

b Press down firmly over the handle to seat the backplane in its connector.

c Pivot the release latch out into the securing slot in the chassis.

d Connect the CD drive interface cable to the CD_ROM connector on the backplane board.

e Connect the diskette-drive interface cable to the FLOPPY connector on the backplane board.

f Press 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.

13 Install the optional security screw (if applicable). See Figure 1-1.

14 Reconnect the system and peripherals to their electrical outlets, and turn them on.

15 Install the optional front bezel (if applicable).

16 If the 100-Mbps RAC Ethernet connector on the back of the system has not been used 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.

18 Update the ERA/O card with the latest version of the ERA/O firmware, available at the Dell Support website at support.dell.com.

See the RAC documentation provided on the documentation CD for information about updating the firmware.

Removing 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.

1 Perform steps 1–7 in "Installing an ERA/O Card."
2 Push open the two retention clips nearest the ERA/O card connector while lifting that end of the card from the connector. See Figure 1-4.
3 Push open the remaining two retention clips and remove the card completely.
4 Perform steps 10–15 in "Installing an ERA/O Card."
5 Disconnect the network cable from the RAC Ethernet connector (if applicable). See Figure 1-5.
