This completes the procedure for returning the system to service.
Installing or Removing a Memory DIMMThe Silicon Graphics Prism Deskside visualization system is configured with a minimum of 2-GB of on-board system memory and a maximum of 24 GB of memory. Memory is contained on small cards that are referred to as DIMMs (dual inline memory modules). Each deskside system can contain four, eight, or twelve DIMMs installed in DIMM slots located on the system node (mother) board.
The memory DIMM sockets are divided into three 4-DIMM groups (groups 0, 1, and 2). The instructions in the following sections assume that you know the correct slots in which to install the memory DIMMs. For information about DIMM configurations and placement rules, continue reading the rest of this section.
Instructions are provided in the following sections:
These twelve DIMM slots are organized into three groups of four DIMMs each, as shown in Figure 3-8. DIMMs are installed one per DIMM slot, and four at a time (group of four). Follow 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, different groups of DIMMs can differ in memory size or speed.
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 maximum bus speed for a completely full set of DIMM memory slots (three installed groups), defaults to 100 MHz or 133 MHz, depending on the type of DIMMs installed.
| Note: The DIMMs used in the Silicon Graphics Prism Deskside visualization platform are not compatible with DIMMs used in the Origin 200, Origin 300, Origin 350 series, Origin 2000, Origin 3000, SGI 3000 series, SGI 2000 series, Onyx systems, Fuel, Octane Octane2, O2, O2+, or Tezro systems.
|
| 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 your wrist and to a grounded connection on your system when you install or remove a component.
|
To remove a DIMM, follow these steps:
Locate the DIMM that you want to remove.
Remove the DIMM, as follows (see Figure 3-9):
Push out and down on the two ejector latches (located at each end of the DIMM socket) to disengage the DIMM from its connector.
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.
|
Place the DIMM on an ESD-safe surface.
If you are installing a new DIMM, proceed to “Installing a DIMM Group”. If you are not installing new DIMMs, repeat the procedures until all the DIMMs have been removed from the group.
Place the DIMM(s) in an antistatic bag and store in a secure location.
 | Important: The four sockets in a DIMM bank must always be either empty or fully populated. The system will not function if there are no memory DIMMs installed. Four memory DIMMs of equal capacity and speed must always be installed in DIMM bank (group) zero. See Figure 3-8.
|
To install a DIMM group, follow these steps:
Power off the Silicon Graphics Prism Deskside platform. For specific powering off instructions, see “Powering Off the System” in Chapter 1.
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.
|
Install the DIMMs, as follows:
Ensure the ejector latches are in the open position (leaning away from the slot).
Hold the DIMM only by its edges and remove it from its antistatic package.
Align the bottom edge of the DIMM with the keyed socket. Make sure that the notches on the bottom of the DIMM align with the protrusions in the bottom of the socket (see Figure 3-10).
Insert the bottom edge of the DIMM into the socket, and then press 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. See Figure 3-11 for an example.
When the DIMM is fully seated in the connector, the ejector latches snap into place flush with each end of the DIMM.
Verifying Memory InstallationTo verify the memory installation, follow these steps:
After you power on the system, check the amount of memory displayed for Main Memory. Use the /usr/share/hwinfo inquiry to determine if the new memory installation is recognized.
The displayed memory should equal the original amount of memory minus any memory you removed, plus the amount of memory you installed.
If the amount of memory is incorrect, power off the system and check the following:
Check the angle of the DIMMs. They should be upright and completely seated.
Ensure that each group is populated with four DIMMs, and that they are the same memory size and speed. You must have either 4, 8, or 12 DIMMs installed.
