Back to Contents Page Installing System Board Options Dell™ PowerEdge™ 2550 Systems Installation and Troubleshooting Guide Expansion Cards Adding Memory Upgrading the Microprocessor or Installing a Secondary Microprocessor Activating the Integrated RAID Controller Replacing the Battery This section describes how to install expansion cards, memory, and microprocessors and how to activate the system's integrated redundant array of independent disks (RAID) controller.
Expansion Cards Expansion cards are installed on the system's riser board (see Figure 8-2). The riser board plugs into the RISER connector on the system board (see Figure 81) and is considered an extension of the system board. The riser board contains three full-length 64-bit, 33-megahertz (MHz), Peripheral Component Interconnect (PCI) expansion-card connectors. All three expansion card connectors support 5-V or universal PCI cards.
3. Remove the expansion-card cage (see "Removing and Replacing the Expansion-Card Cage" in "Checking Inside the System"). NOTE: Verify that the power LED on the riser board (see Figure 8-2) is off before removing the expansion-card cage. 4. Open the expansion-card latch (see Figure 8-3) and remove the filler bracket from the expansion slot. Figure 8-3. Installing an Expansion Card 5. Install the new expansion card (see Figure 8-3).
10. Replace the expansion-card cage in the chassis (see "Removing and Replacing the Expansion-Card Cage" in "Checking Inside the System"). 11. Close the system doors, reconnect the system and peripherals to their electrical outlets, and turn them on. Adding Memory The four dual in-line memory module (DIMM) sockets on the system board (see Figure 8-1) can accommodate from 128 megabytes (MB) to 4 gigabytes (GB) of registered synchronous dynamic random-access memory (SDRAM).
WARNING: See "Protecting Against Electrostatic Discharge" in the safety instructions in the System Information document. 1. Open the system doors (see "Opening the System Doors" in "Checking Inside the System"). 2. Locate the memory module sockets in which you will install or replace memory modules. Figure 8-1 shows the general location of the memory module sockets on the system board. Figure 8-4 shows the order of the memory module sockets. 3.
Upgrading the Microprocessor or Installing a Secondary Microprocessor To take advantage of future options in speed and functionality, you can add a second processor or replace either the primary or secondary processor. NOTICE: The second processor must be of the same type and speed as the first processor. Each processor and its associated level 2 (L2) cache memory are contained in a Flip Chip Pin Grid Array (FC-PGA) package that is installed in a zero insertion force (ZIF) socket on the system board.
3. Remove the heat sink. NOTICE: Be careful not to bend any of the pins when removing the microprocessor chip. Bending the pins can permanently damage the microprocessor chip. 4. Remove the microprocessor chip from the socket by pulling the socket release lever straight up until the chip is released (see Figure 8-8) and then lift the chip out of the socket. Leave the release lever up so that the socket is ready for the new microprocessor. Figure 8-8.
9. Place the new heat sink on top of the microprocessor chip (see Figure 8-11). NOTE: To avoid possible damage to the microprocessor, you must align the heat sink so that the triangular mark on the heat sink points toward the triangular mark on the system board. 10. To replace the retention clip, orient the clip so that the release tab is adjacent to the triangular marks on the heat sink and the system board.
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.
7. Insert the RAID battery into the bracket on the underside of the system door (see Figure 8-14). Figure 8-14. Installing the RAID Battery 8. Connect the battery cable to the RAID battery connector on the system board (see Figure 8-1). 9. Close the system doors, reconnect the system and peripherals to their electrical outlets, and turn them on. 10. 11. Install the RAID software. For details, see the RAID controller documentation.
You can operate the system without a battery; however, the system configuration information maintained by the battery in NVRAM is erased each time you shut down the system. Therefore, you must re-enter the system configuration information and reset the options each time the system boots until you replace the battery. The battery is a 3.0-volt (V), coin-cell CR2032-type battery. To remove the battery, perform the following steps.
Back to Contents Page Installing a Drive in the Peripheral Bay Dell™ PowerEdge™ 2550 Systems Installation and Troubleshooting Guide Before You Begin Installing a Device That Uses the System's Integrated SCSI Controller Installing a Tape Drive That Uses a Controller Card Connecting an External Tape Drive The open peripheral bay at the front of your system can accommodate a user-accessible, half-height 5.25-inch device, such as a tape drive. This peripheral bay is contained in a removable peripheral cage.
SCSI ID Numbers Each device attached to a SCSI host adapter must have a unique SCSI ID number from 1 to 7. When SCSI devices are shipped from Dell, the default SCSI ID numbers are assigned as follows: l A SCSI tape drive is configured as SCSI ID 6 (the default ID number for a tape drive). l A SCSI CD-ROM drive is usually configured as SCSI ID 5. NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or that devices be attached to the cable in order by ID number.
