3. Check any cables connected to expansion cards through the back-panel open-
ings. Disconnect any cables that will not reach to where the cage must be placed
upon removal from the chassis.

4. Locate the expansion-card cage securing lever (see Figure 1-1). Rotate the lever
upward until it stops in an upright position.
5. Lift the expansion-card cage up and away from the chassis.
6. Open the expansion-card latch (see Figure 1-2) and remove the filler bracket from

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 system’s 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 User’s 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 card’s 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.

support.dell.com Dell PowerEdge 2450 Systems Information Update 1-5
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. Don’t 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.

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 system’s 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

2. Replace the air blower, if it was removed in step 3 of the previous procedure (see
Figure 1-3).
a. Position your right thumb on the outside of the power supply enclosure
beside the narrower front part of the air blower.
b. Push firmly on the power supply enclosure to move it slightly toward the
power supplies, allowing extra clearance to install the air blower.
c. Hold the air blower above the heat sink while tilting the back of the air blower
slightly down and toward the back of the chassis.
d. Slide the metal tab at the back right of the air blower carefully into the
topmost slot at the top back of the chassis.
e. With your left hand, push down firmly on the front of the air blower until you
hear it snap into place.
f. Make sure that the top of the air blower is level; if it is not level, lift out the air
blower and reinstall it making sure the tab goes into the slot at the very top
of the back chassis.
g. Plug in the Y-shaped blower power cable to the connector on the interposer
board.
