PCI and PCI–X Cards

Your system module and various optional modules in your system support optional PCI and PCI–X cards.

The following instructions, which describe how to install and remove a PCI or PCI–X card from the system base compute module, can also be used to install and remove a PCI or PCI–X card from an expansion compute module.

Figure 6-3 shows the rear of the module. The PCI and PCI–X card slot is located on the left-rear side in the base compute module.

For an updated list of supported PCI and PCI-X cards, see the SGI Supportfolio at:

http://support.sgi.com .

This section describes the following:

Rules for Card Installation and Removal

When installing or removing a PCI or PCI–X card from your system, be aware of the following precautionary rules:


Caution: Electronic equipment can be irreparably damaged by electrostatic discharge (ESD). Always follow these preventive measures when you handle a system component:

- Remove a component from its antistatic bag only when you are ready to install it.

- If you handle a component before installation, do not place it on surfaces that produce ESD (carpeting, for example) or near devices that create static electricity.

- Attach a static wrist strap to a grounded connection on your system when you install or remove a component.

Each Altix 330 module supports one PCI/PCI-X option card.

Installing or Replacing a PCI or PCI-X Card

To remove, replace, or install a PCI or PCI–X card, follow these steps:

  1. Power off the server system. For power off instructions, see “Powering the System On and Off Manually” in Chapter 1.

  2. Disconnect all of the cables at the rear of the module. The module power cable should be disconnected from the power source and freed from any obstructions.


    Warning: Components may be hot. To avoid injury, allow the components to cool for approximately five minutes before you proceed with these instructions.


  3. If your module is rackmounted, remove the two screws that secure the module retaining brackets to the front rails of the rack. If your module is not rackmounted, proceed to step 5.

  4. Preferably using two people, pull the module from the rack carefully (do not pull on the plastic front panel). Support the unit from below and place it on a stable work surface. The power cable will come out with the module.

  5. Open the top cover as described in “Accessing the System's Internal Components”.

  6. Make sure that you read “Safety Instructions ”, and “Rules for Card Installation and Removal” before beginning your card installation.

  7. If you are replacing an existing PCI/PCI-X card remove it as shown in Figure 6-4. If there is only a blank panel in the slot, go on to the next step and remove it.

    Figure 6-4. Removing an Installed Optional PCI/PCI-X Card

Memory DIMM Group Placement and Guidelines

Memory is contained on cards that are referred to as DIMMs (dual inline memory modules). Each server system base compute module and system expansion compute module can contain four, or eight DIMMs installed in DIMM slots located on the module's mother board.

These eight DIMM slots are organized into two groups of (4 DIMMs each) as shown in Figure 6-10.

DIMMs are installed one per DIMM slot, and four at a time (group of four).

You must note these guidelines when installing DIMM groups:

  • Memory is increased or decreased in four-DIMM group increments only.

  • Each of the four DIMMs that make up a DIMM group must be the same memory size and speed; however, the two 4-DIMM groups can differ in memory size.

  • The first four DIMMs (group 0) must be in place for the base module to operate properly.

  • Mixing DIMM groups with different access speeds will cause the memory bus to default to the speed used for the slowest group.

  • The DIMMs used in the Altix 330 server system base compute module, or expansion compute module, are not compatible with DIMMs used in the Origin 200, Origin 300, Origin 350 series, SGI 3000 series, SGI 2000 series, Onyx systems, Fuel, Octane or Tezro systems.


    Note: Installation of DIMMs not certified or approved by SGI for use in the Altix 330 may impair the functionality or performance of your system. Installation of DIMMs not approved by SGI may also violate your warranty and/or support contract. Check with your SGI sales or service representative before installing any DIMMs not specifically designated for the Altix 330.

    Caution: Electronic equipment can be irreparably damaged by electrostatic discharge (ESD). Always follow these preventive measures when you handle a system component:

    - Remove a component from its antistatic bag only when you are ready to install it.

    - If you handle a component before installation, do not place it on surfaces that produce ESD (carpeting, for example) or near devices that create static electricity.

    - Attach a static wrist strap to a grounded connection on your system when you install or remove a component.


Installing or Replacing a DIMM Group

To install or replace a DIMM group, follow these steps:

  1. Power off the server system. For powering off instructions, see “Powering the System On and Off Manually” in Chapter 1.

  2. Disconnect all of the cables at the rear of the module.


    Warning: Components may be hot. To avoid injury, allow the components to cool for approximately five minutes before you proceed with these instructions.


  3. If your module is rackmounted, remove the two screws that secure the module retaining brackets to the front rails of the rack. If your module is not rackmounted, proceed to step 5.

  4. Preferably using two people, pull the module from the rack carefully (do not pull on the plastic front panel). Support the unit from below and place it on a stable work surface. The power cable will come out with the module.

  5. Open the top cover as described in “Accessing the System's Internal Components”.

  6. If you need to remove a DIMM or DIMM group, use the following substeps:

    1. Push out and down on the two ejector latches (located at each end of the DIMM socket) to disengage the DIMM from its connector, see Figure 6-11.

    2. Carefully grasp the DIMM and pull it up and out of the guide rails.


      Note: Hold the DIMM only by its edges. Be careful not to touch its components or gold edge connectors.


    3. Place the DIMM on an ESD-safe surface or in an anti-static bag.

  7. If you are installing a new DIMM(s), proceed to the next steps.

    Figure 6-11. Removing a DIMM

    Removing a DIMM


    Note: If you need to find the correct locations in which to install the DIMMs, make sure to read the introductory material in “Memory DIMM Group Placement and Guidelines”.


Install the DIMMs, as follows (see Figure 6-12):

  1. Ensure the ejector latches are in the open position (leaning away from the slot).

  2. Hold the DIMM only by its edges and remove it from its antistatic package.

  3. Align the bottom edge of the DIMM with the keyed socket.

  4. Insert the bottom edge of the DIMM into the socket, and then press down evenly on the DIMM until it seats correctly. Use extreme care when you install a DIMM. If you apply too much pressure, you can damage the socket.

  5. When the DIMM is fully seated in the connector, the ejector latches snap into place flush with each end of the DIMM, see Figure 6-12. Repeat until all DIMMs are installed.
