Chapter 2. Installing or Removing Memory and Option Boards

This chapter explains how to install or remove DIMMs (double in-line memory modules), PCI option boards, or a digital display option board. The following topics are covered:

Removing the System Module

Before installing memory or option boards, you must follow these steps:


Note: The illustrations show an O2+ RM7000class workstation. The process of installing and removing the system module is the same for the O2+ R12000class workstation.


  1. Turn off the workstation by pressing the power button on the front (Figure 2-1).

    Figure 2-1. Turning Off the O2+ Workstation

    Turning Off the O2+ Workstation

  2. Remove the power cable from the rear (Figure 2-2).


    Caution: Always remove the power cable before removing the system module from the workstation.

    When you walk quickly across a room, or sit down or stand up, you build up a lot of static electricity. To perform any of the hardware tasks on the system module, you should stand in one place until you have completed the task.

    Figure 2-2. Disconnecting the Power Cables

    Disconnecting the Power Cables

  3. The system module is on the left as you face the rear. Pull down the lever on the left side of the module to release it (Figure 2-3).


    Note: You do not need to remove the cables from the system module, if you are careful when handling it. But you may find it easier to work if the cables are removed.


    Figure 2-3. Pulling Down the Lever on the System Module

    Pulling Down the Lever on the System Module

  4. Slide the system module out of the chassis (Figure 2-4).

    Figure 2-4. Remove the System Module from the Chassis

    Remove the System Module from the Chassis

  5. Lay the system module on a clean, flat surface, such as your desktop (Figure 2-5).

    Figure 2-5. Laying the System Module on a Flat Surface

Now that you have removed the system module, you can perform the following activities:

Installing Memory Modules

To see a 3D animation of installing memory modules, see Hardware Central . When the browser window opens, see “Hardware Overview” and then “Installing Memory Modules.” (If your Web browser is not loaded, it takes a few seconds to load.) If you are viewing this on a remote server, the 3D animation is not available.


Caution: The O2+ workstation uses DIMMs (Double Inline Memory Modules). DIMMs are extremely sensitive to static electricity. Handle the modules carefully, and wear the wrist strap while installing them.



Note: The illustrations show an O2+ RM7000class workstation. The process of installing and removing memory modules is the same for the O2+ R12000class workstation. Also note that DIMMs cannot be installed on earlier workstations that used SIMMs.

To install memory modules, follow these steps:

  1. If you have not already done so, remove the power cable, and remove the system module from the chassis. See “Removing the System Module”.

  2. Components on the system module are extremely sensitive to static electricity. Before touching any of the components, ground yourself to a metal part of the chassis, as follows:

    • Unwrap the first two folds of the wrist strap and wrap the exposed adhesive side firmly around your wrist.

    • Unroll the rest of the strap and peel the liner from the copper foil at the opposite end.

    • Attach the copper foil to the PCI tray. Attach the wrist strap to your wrist and to the PCI tray (Figure 2-6).

      Figure 2-6. Attaching the Wrist Strap

      Attaching the Wrist Strap

  3. Familiarize yourself with the memory (DIMM) banks (Figure 2-7) and (Figure 2-8). There are four banks comprised of eight sockets, numbered 1 through 8. Two sockets form a bank.

    The minimum configuration has 256 MB of memory—one 128-MB module installed in slot 1 and one 128-MB module installed in slot 2.

    Figure 2-7. Locating the DIMM Banks

    Locating the DIMM Banks

    Figure 2-8. Top View of the DIMM Banks

    Top View of the DIMM Banks

  4. Read the following guidelines and then proceed to the next step.

    • Slots 1 and 2 must always be populated.

    • High-density DIMMs must always be installed in the lowest slots, that is, slots 1 and 2.

    • Install the DIMMs in groups of two, with DIMMs of the same capacity in each bank of two. You cannot mix capacities in one bank.

    • In a bank of two slots, both slots must have a DIMM or both slots must be empty (except for slots 1 and 2, which must always be populated). For example, you can install a 128-MB module in slot 3, a 128-MB module in slot 4, a 64-MB module in slot 5 and a 64-MB module in slot 6. But you cannot install a 128-MB module in slot 3 and a 64-MB module in slot 4.


      Note: If you need to remove a DIMM, see “Removing Memory Modules”.


  5. Install the DIMMs consecutively in groups of two, beginning with the lowest open slot (Figure 2-9), as follows:

    • Hold the DIMM over the socket without tilting it.

    • Lower the DIMM, pushing it straight down into the socket gently but firmly. You hear a click as it is seated and the latches on each side of the module snap up.

      Figure 2-9. Installing the Memory Modules

      Installing the Memory Modules

  6. Check the DIMMs visually to make sure they are installed correctly (Figure 2-10), as follows:

    • The tops of the DIMMs of the same capacity should be even.

    • The DIMMs should all be absolutely vertical (no leaning).

    • The latches on the sides should fit snugly against each DIMM.

      Figure 2-10. Checking the DIMM Installation

      Checking the DIMM Installation

  7. Remove the wrist strap and follow the steps in “Reinstalling the System Module”.

Removing Memory Modules

To remove memory modules, follow these steps:

  1. If you have not already done so, remove the power cable, and remove the system module from the chassis. See “Removing the System Module”.

  2. Before touching any of the components, ground yourself to a metal part of the chassis, as follows:

    • Unwrap the first two folds of the wrist strap and wrap the exposed adhesive side firmly around your wrist.

    • Unroll the rest of the strap and peel the liner from the copper foil at the opposite end.

    • Attach the copper foil to the PCI tray. Attach the wrist strap to your wrist and to the PCI tray (Figure 2-11).

      Figure 2-11. Attaching the Wrist Strap

      Attaching the Wrist Strap

  3. Remove the DIMM by pushing down the latches on both sides to release it. Pick up the DIMM and set it aside (Figure 2-12).

Verifying the Hardware Installation

Once you have installed memory modules or an option board, you should verify that the system recognizes the new hardware, as follows:

  1. Log in to your account.

  2. From the Toolchest (Figure 2-55), select System > System Manager > About This System.

    Figure 2-55. The Toolchest

    The Toolchest

  3. If you installed memory, look under the Hardware menu. Check the amount of memory shown. It should equal the total amount that you installed.

    For example, if you had 32 MB of memory when you started and you installed another 64 MB, the total shown should be 96 MB.

    If the system does not show the total amount of memory you installed, turn off the workstation, remove the power cable, remove the system module, and make sure all the DIMMs are installed correctly.

  4. If you installed a PCI option board , from a shell window, enter:
    hinv

    This shows the hardware inventory for your workstation. Look for a line describing the board you installed. For some option boards, the software must be installed before the board is shown.

    If it is now shown, turn off the workstation, and review the installation steps again to make sure the board is seated correctly. (See “Installing a PCI Board in an RM7000class Workstation”, or “Installing a PCI Board in an R12000class Workstation”.)
