7. Install the new expansion card.  
Position the expansion-card cage so that the riser board lies horizontally on your  
work surface.  
Insert the card-edge connector firmly into the expansion-card connector on the  
riser board, until the card is fully seated.  
8. When the card is seated in the connector and the card-mounting bracket is  
aligned with the brackets on either side of it, close the expansion-card latch.  
9. If the expansion card is a full-length card, secure the inner end of the card by  
closing the latch on the card guide over the top edge of the card.  
10. With the securing lever in the upright position, lower the expansion-card cage  
into place until it is aligned.  
11. Rotate the securing lever downward until it is flush with the top of the chassis.  
Make sure the riser board is fully seated in the RISER connector on the system  
board.  
12. Reconnect any cables you removed in step 3.  
See the documentation that came with the card for information about its cable  
connections.  
13. Close the system doors, and then reconnect the system and peripherals to their  
AC power sources and turn them on.  
To remove an expansion card, perform the following steps:  
1. To release the expansion card from the card cage, rotate the expansion-card latch  
away from the expansion-card bracket.  
2. If the expansion card is a full-length card, release the card's inner end by opening  
the tab on the card guide (see Figure 1-2).  
3. Grasp the expansion card by its top corners, and carefully remove it from the  
expansion-card connector.  
4. If you are removing the card permanently, install a metal filler bracket over the  
empty card-slot opening.  
NOTE: Installing a filler bracket over an empty expansion slot is necessary to  
maintain Federal Communications Commission (FCC) certification of the system.  
The brackets also keep dust and dirt out of the system and aid in proper cooling  
and airflow inside the system.  
5. Replace the expansion-card cage in the chassis as instructed in steps 10 through  
12 of the previous procedure.  
6. Close the system doors, and then reconnect the system and peripherals to their  
AC power sources and turn them on.

Your systems integrated SCSI host adapter supports the Ultra3 (also known as  
Ultra160) SCSI standard as defined by the SCSI Trade Association. The Ultra3 SCSI  
standard supports a combination of new SCSI performance and manageability  
enhancements to increase data throughput up to 160 megabytes per second  
(MB/sec). For specific information about the Ultra3 SCSI standard, see the SCSI Trade  
Association Web site at http://www.scsita.org.  
Your system employs an implementation of Ultra3 (Ultra160) known as Ultra160/m.  
The Ultra160/m and Ultra3 (Ultra160) drives supplied by Dell are identical and are  
interchangeable.  
The subsections describing SCSI and redundant array of independent disks (RAID)  
settings in “Using the System Setup Program,” of your Dell PowerEdge 2450  
Systems Users Guide have been combined to read as follows:  
SCSI/RAID Controller  
Selections are RAID Enabled, SCSI Enabled, and Off. When you set the  
SCSI/RAID Controller to RAID Enabled, Channel A displays RAID and  
Channel B displays SCSI. When you set it to SCSI Enabled, Channel A and  
Channel B display SCSI. When you set it to Off, Channel A and Channel B  
display Off.  
When installing the SCSI backplane daughter card as addressed in “Installing Hard-  
Disk Drives,” of the Dell PowerEdge 2450 Systems Installation and Troubleshooting  
Guide, make sure to slide in the daughter card until it clicks and then lock the card into  
place by closing the retention lever on the cards front edge.

Before you perform any of the procedures in this section, take a few moments to read  
the following warning for your personal safety and to prevent damage to the system  
from electrostatic discharge (ESD).

Before you start to work on the system, perform the following steps in the  
sequence listed:  
1. Turn off your system and any devices.  
1-4  
Dell PowerEdge 2450 Systems Information Update  
Download from Www.Somanuals.com. All Manuals Search And Download.  
2. Ground yourself by touching an unpainted metal surface on the chassis, such as  
the metal around the card-slot openings at the back of the system, before touch-  
ing anything inside your system.  
While you work, periodically touch an unpainted metal surface on the system  
chassis to dissipate any static electricity that might harm internal components.  
3. Disconnect your system and devices from their power sources. Also, disconnect  
any telephone or telecommunication lines from the system.  
Doing so reduces the potential for personal injury or shock.  
In addition, take note of these safety guidelines when appropriate:  
When you disconnect a cable, pull on its connector or on its strain-relief loop,  
not on the cable itself. Some cables have a connector with locking tabs; if  
you are disconnecting this type of cable, press in on the locking tabs before  
disconnecting the cable. As you pull connectors apart, keep them evenly aligned  
to avoid bending any connector pins. Also, before you connect a cable, make sure  
both connectors are correctly oriented and aligned.  
Handle components and cards with care. Dont touch the components or  
contacts on a card. Hold a card by its edges or by its metal mounting bracket.  
Hold a component such as a microprocessor chip by its edges, not by its pins.

Before shutting down your system, perform these preliminary steps:  
Record the system configuration settings.  
Update the embedded server management (ESM) firmware.  
Update the basic input/output system (BIOS), if necessary.  
Use the resource configuration utility (RCU) diskette to save the RCU configura-  
tion settings (see your Users Guide for complete information).  
During the upgrade procedure, you must use a wrist-grounding strap for ESD  
protection.

1. Turn off the system, including any attached peripherals, and disconnect the  
power cable from the electrical outlet.  
2. Open the system cover.  
See your systems Installation and Troubleshooting Guide for specific instruc-  
tions, if needed.  
3. Remove the air blower, if present (see Figure 1-3).  
a. Unplug the Y-shaped air blower power cable from the interposer board.  
b. Position your right thumb on the outside of the power supply enclosure  
beside the narrower front part of the air blower.  
c. Push firmly on the power supply enclosure to move it slightly away from the  
air blower and allow extra clearance to remove the air blower.  
d. With your left hand, pull the front of the air blower upward and away from  
the power supplies to unseat it. You should hear it unsnap.  
By pulling the air blower slightly away from the power supplies, you avoid the  
need to use excessive force to clear the power supply enclosure.  
e. Slide the air blower slightly up and toward the front of the chassis until the  
metal tab at the back right of the air blower slides out of the small slot at the  
top back of the chassis.
