This document updates information on the following topics for your
Dell PowerEdge 2450 system:
Installing and removing expansion cards
Small computer system interface (SCSI) hard-disk drive support
Installing an upgrade microprocessor in PowerEdge 2450 systems
To install an expansion card, perform the following steps.

1.
Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2.
Prepare the expansion card for installation, and open the system doors.

,
-
See the documentation that came with the expansion card for information on
configuring the card, making internal connections, or otherwise customizing the
card for your system.
3.
Check any cables connected to expansion cards through the back-panel openings. Disconnect any cables that will not reach to where the cage must be placed
upon removal from the chassis.

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 HardDisk 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.

This section provides instructions for:
Removing the single edge contact (SEC) cartridge and heat sink
Installing the new SEC cartridge and heat sink
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.
1-4
Turn off your system and any devices.
Dell PowerEdge 2450 Systems Information Update
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 touching 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.

Update the basic input/output system (BIOS), if necessary.
Use the resource configuration utility (RCU) diskette to save the RCU configuration settings (see your User’s Guide for complete information).
During the upgrade procedure, you must use a wrist-grounding strap for ESD
protection.
