NOTICE: The cooling fans are hot-pluggable. To maintain proper cooling while the system is on, replace only one fan at a time.
  1. Locate the faulty fan and while squeezing the fan release levers, lift the fan straight up to clear the fan assembly (see Figure 6-4).

Figure 6-4. Removing/Replacing a Fan

Replacing a Fan

  1. Lower the fan into the fan assembly until the fan snaps into position.

  2. Replace the system cover (see "Replacing the System Cover" in "Troubleshooting Your System").

Power Supplies

  1. Open the front bezel (see "Removing the Front Bezel" in "Troubleshooting Your System").

NOTICE: The power supplies are hot-pluggable. The system requires three power supplies to be installed for the system to operate normally. The system is in the redundant mode when all four power supplies are installed. Remove and replace only one power supply at a time.
  1. Remove the power supply by grasping the power supply handle, pressing down on the release lever, and pulling the power supply straight out to clear the chassis (see Figure 6-5).

Figure 6-5. Removing and Installing the Power Supply

  1. Install the new power supply by sliding the new power supply into the chassis until it snaps into place.

  2. Close the front bezel (see "Replacing the Front Bezel" in "Troubleshooting Your System").

Expansion Cards

Seven expansion card slots are available in the system. Expansion-card slots 2 through 7 are hot-pluggable and capable of operating at 33, 66, or 100 MHz. These six expansion-card slots are on three different buses. Slots 2 and 3 are on one bus, slots 4 and 5 are on another bus, and slots 6 and 7 are on a third bus. If you are installing a remote access card, it must be installed in slot 1. Slot 1 is not hot-pluggable and operates at 33 MHz.

You can install expansion cards of different operating speeds on the same bus; however, the bus will operate at the slowest operating speed of the cards on that bus. For example, if one card on the bus has an operating speed of 66 MHz and the other card has an operating speed of 100 MHz, the bus will only operate at 66 MHz.

For optimum performance, you may want expansion cards are on the same bus to have the same operating speed.

Installing an Expansion Card

CAUTION: If you are installing an expansion card in expansion-card slot 1, you must turn off the system and disconnect it from its power source. For more information, see "Safety First—For You and Your System" in "Troubleshooting Your System."
CAUTION: If your system's operating system does not support hot-plug PCI or PCI-X expansion cards or the expansion card itself does not support hot-plug installation, turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet.
  1. Unlock and open the expansion-card access cover.

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.

NOTICE: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document.
  1. Rotate the expansion-card latch, and remove the filler bracket from the expansion-card slot (see Figure 6-6).

  2. If your system's operating system does not support hot-plug expansion cards, turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet.

If your system's operating system does support hot-plug expansion cards, press the switch next to the expansion-card slot and wait until the LED turns off.

  1. Install the expansion card (see Figure 6-6):

    1. Position the expansion card so that the card-edge connector aligns with the expansion-card connector on the system board.

    1. Insert the card-edge connector firmly into the expansion-card connector until the card is fully seated.

Figure 6-6. Installing an Expansion Card

  1. 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.

  2. Connect any cables that should be attached to the card.

See the documentation that came with the card for information about its cable connections.

NOTE: SCSI cables connected from an expansion card to the SCSI backplane board should be routed under the front fan assembly.
NOTE: If there is an expansion card in the other expansion card slot on that bus and the expansion card that you are installing has a different operating speed, you must also power down the expansion card that is already installed. This will ensure that both expansion cards on that bus will power up at the slower operating speed.
  1. Press the switch next to the expansion card that you installed and wait until the LED turns green.

If you turned off your system in step 3 due to your system's operating system not supporting hot-plug expansion cards, close the expansion-card access cover, reconnect the system to its electrical outlet, including any attached peripherals, and turn on the system.

  1. Close the expansion-card access cover.

Adding Memory

The memory modules are contained on two memory riser cards. Each riser card has six memory module sockets. Between the two memory riser cards, the system can accommodate 512 MB to 12 GB of registered memory modules. The memory module sockets on each riser card are arranged in pairs (A and B) on three banks (1– 3). Memory modules must be installed in at least one bank on each memory riser card for the system to operate. The memory modules should be installed starting with bank 1, then bank 2, and then bank 3 (see Figure 6-9). Each bank on each memory riser card must contain the same memory module size. For example, if bank 1 on one riser card contains 128-MB memory modules, bank 1 on the other riser card must also contain 128-MB memory modules.

To obtain the desired total memory for your system, you may need to install memory modules of different sizes. This is supported as long as the memory modules installed in each bank are the same size and the largest size is installed in bank 1. For example, if you wanted the total memory in your system to be 6 GB, each memory riser card configuration could be as follows:

Table 6-2. Sample Memory Riser Card Configuration

Memory Riser Card A

Memory Riser Card B

Bank 1 = 2 GB

Bank 1 = 2 GB

Bank 2 = 1 GB

Bank 2 = 1 GB

Memory Upgrade Kits

The system is upgradable to 12 GB by installing combinations of 128-, 256-, 512-MB, and 1-GB registered memory modules. You can purchase memory upgrade kits as needed.

NOTE: The memory modules must be PC-1600 compliant.

Memory Module Installation Guidelines

Starting with the socket nearest the top of the memory riser card, the memory module sockets are labeled BANK1_A and BANK1_B through BANK3_A and BANK3_B (see Figure 6-9). When you install memory modules, follow these guidelines:
