Dell PowerEdge 2550 - Manual (Page 72)

12. Close the system doors.
13. Reconnect your system and peripherals to their electrical outlets, and turn them on.
14. Press to enter the System Setup program, and check that the microprocessor categories match the new system configuration. See the system's
User's Guide for instructions.
15. As the system boots, it detects the presence of the new processor and automatically changes the system configuration information in the System Setup
program.
16. Enter the System Setup program, and confirm that the top line in the system data area correctly identifies the installed processor(s). See "Using the
System Setup Program" in your User's Guide.
17. While in the System Setup program, reset the chassis intrusion detector.
18. Run the Dell Diagnostics to verify that the new microprocessor is operating correctly. See " Running the Dell™ Diagnostics ," for information on running
the diagnostics and troubleshooting any problems that may occur.
Activating the Integrated RAID Controller
To activate the integrated PowerEdge™ Expandable RAID Controller (PERC) 3/Di, perform the following steps.
1. Open the system doors (see " Opening the System Doors " in "Checking Inside the System").
2. Remove the expansion-card cage (see " Removing and Replacing the Expansion-Card Cage " in "Checking Inside the System").
3. Open the ejectors on the RAID controller memory module socket by pressing down and outward, as shown in Figure 8 -5 , to allow the memory module
to be inserted into the socket.
See Figure 8 -1 for the location of the socket on the system board.
4. Align the memory module's edge connector with the slot in the center of the memory module socket, and insert the memory module into the socket (see
Figure 8 -5 ).
The memory module socket has two alignment keys that allow the memory module to be installed in the socket in only one way.
5. Press on the memory module with your thumbs while pulling on the ejectors with your index fingers to lock the memory module into the socket (see
Figure 8 -5 ).
6. Examine the RAID hardware key (see Figure 8 -13 ) to ensure that it is labeled "PE25X0." Hardware keys intended for use in other systems will not
enable the RAID controller. If the key is the correct type, install the key in its socket on the system board (see Figure 8 -1 ) and secure the key with the
latches on each end of the socket (see Figure 8 -13 ).
Figure 8-13. Installing the RAID Hardware Key
NOTE: After you remove and replace the cover, the chassis intrusion detector will cause an alert message to be displayed at the next system start-up.
NOTE: If a setup password has been assigned by someone else, contact your network administrator for information on resetting the chassis intrusion
detector.
WARNING: Before you perform this procedure, you must turn off the system and disconnect it from its electrical outlet. For more information, see
"
Safety First—For You and Your Computer " in "Checking Inside the System."
NOTICE: To avoid possible data loss, back up all data on the hard-disk drives before changing the mode of operation of the integrated SCSI controller
from SCSI to RAID.
WARNING: See "Protecting Against Electrostatic Discharge" in the safety instructions in the System Information document.
NOTE: Verify that the power LED on the riser board (see Figure 8 -2 ) is off before removing the card cage.
NOTE: The RAID controller memory module must be an unbuffered memory module, rated to run at 100 MHz or faster. Do not substitute registered
memory modules such as those used for system memory.
