Replacing a Power Supply

  1. Slide the new power supply into the chassis (see Figure 6-3).

  2. Rotate the power supply handle up until it snaps into place, securing the power supply to the chassis.


AC Power Module

Your system can operate with an AC module or an integrated redundant AC power module. The AC module is used when a redundant AC power source is not required. The integrated redundant AC power module enables your system to use two AC inputs. Your system can operate on either of these inputs and automatically switches from a failing AC power source. Both of these modules are removed and replaced using the same procedure.

Removing the AC Power Module

  1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.

  2. Loosen the thumbscrew that secures the AC power module to the chassis.

  3. Remove the AC power module by grasping the handle and pulling the module straight out to clear the chassis (see Figure 6-4).

  2. Tighten the thumbscrew that secures the AC power module to the chassis.

  3. Connect the system to the electrical outlet and turn on the system, including any attached peripherals.


Expansion Cards

The system includes 11 hot-pluggable expansion slots. Slot 1 operates at 33 MHz. Slots 2 through 11 are capable of operating at 33, 66, or 100 MHz. The expansion slots are on six different PCI buses (see Figure A-5 for expansion-slot buses and operating speeds).

Expansion-Card Installation Guidelines

Use the following guideline when installing expansion cards:

PCI Bus Scan Order

The system's BIOS scans and numbers PCI buses and devices during startup. Expansion slots are scanned according to the host bus ordering, not by the slot numbers. See Table 6-1 for the order in which the expansion slots and embedded PCI devices are scanned. Figure A-3 provides a diagram of the PCI buses and expansion slots.

Several additional factors affect the assignment of PCI bus numbers:

If you install expansion cards, you may have some difficulty in directly determining the bus number of a controller on a particular expansion card. However, the PCI bus scan order listed in Table 6-1 can help you determine the relative numbering of PCI buses within the expansion slots. For example, a PCI controller residing in expansion slot 3 will never have a lower bus number than one in slot 2 because slot 2 precedes slot 3 in the scan order.

Memory Modules

The memory modules are contained on two memory riser cards. Each riser card has eight memory module sockets. Between the two memory riser cards, the system can accommodate from 512 MB to 16 GB of registered memory. The memory module sockets on each riser card are arranged in pairs (A and B) on four banks (1–4). 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 and ending with bank 4 (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. 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 16 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

Memory module sockets are arranged in pairs, labeled A and B, on each memory riser card. A pair of sockets on each memory riser card forms a single memory bank. See Figure 6-9 to identify the sockets on a memory riser card.

When you install memory modules, follow these guidelines:
