Using two people, insert the enclosure back into the rack and secure it with the two screws you removed in step 1.
The rack-mountable workstation supports PCI and PCI–X cards. The following procedure describes how to install and remove a PCI or PCI–X card from a workstation. This procedure applies to both the first enclosure and the optional second enclosure. Figure 3-3 shows the location of the PCI and PCI–X card slots in both the first and second enclosures.
For an updated list of supported PCI and PCI–X cards, see SGI Supportfolio at http://support.sgi.com.
This section explains how to perform the following procedures:
To install a PCI or PCI–X card, follow these steps:
Power off the system. For instructions on how to power off the system, see “Using the Workstation” in Chapter 1.
Disconnect all of the cables at the rear of the system.
Warning: Components may be hot. To avoid injury, allow the components to cool for approximately five minutes before you proceed with these instructions. If your system is rackmounted, remove the two screws that secure the enclosure to the front rails of the rack. If your system is not rackmounted, proceed to the next step.
If you are installing a card in one of the two lowermost card slots, you must also remove the lower PCI/PCI–X support bracket that covers the two lowermost slots as shown in Figure 3-4 by removing the four Phillips screws.
If a blanking plate covers the slot that is needed for the installation, remove the retaining screw as shown in Figure 3-5 and the blanking plate.
If you want to install a PCI/PCI–X card, insert the card into the slot by pushing the card into the connector until it is properly seated and install the retaining screw as shown in Figure 3-6. If you have installed a card (not an IO9 card) into one of the two lowermost slots, proceed to step 12. If you have installed the card into one of the upper two slots, proceed to step 14.
If you have installed a card in one of the two bottom–most card slots, replace the lower PCI/PCI–X support bracket that covers the two bottom–most slots and screw in the four Phillips screws as shown in Figure 3-7.
Caution: To prevent pinching and damaging of the IDE and SCSI cables, make sure that both of these cables are tucked underneath the IO9 card and safely away from the lower PCI/PCI–X support bracket that you are replacing. Close the hinged cover on the system and screw in the ten Phillips screws you removed to secure the cover as shown in Figure 3-2.
If your system is rackmounted, proceed to the next step. If your system is free-standing, proceed to step 13.

Each workstation enclosure can contain one or two sled-mounted Ultra 160 SCSI disk drives (see Figure 3-12). This section explains how to install and remove a disk drive.
| Note: The second enclosure in a dual-enclosure workstation must have an IO9 card in order to support disk drives. |
To install a disk drive, follow these steps:
Open the bezel door as far as it will open. Position the drive assembly so that it engages the bay guide rails and, with the locking handle fully swung open, gently push in the drive into the bay until the locking handle engages with left side of the bay opening as shown in Figure 3-13A.
Note: If you will have only one disk drive in your system, it should be located in the bottom–most slot. Swing the locking handle towards the chassis until the locking handle engages the latch as shown in Figure 3-13B and Figure 3-13C.
Close the bezel door as shown in Figure 3-13D.
To remove a disk drive, follow these steps:
If you are replacing a data drive, ensure that the drive has spun down before you remove it.
If you are replacing the system drive, you must first halt the operating system using a command such as /etc/shutdown or /etc/halt and then power off the system.
Open the bezel door located on the left side of the front panel of the enclosure as shown in Figure 3-14A. (Make sure that you open the door as far as it will open.)
Remove the drive by depressing the locking handle with your forefinger (see Figure 3-14B) and swing open the locking handle away from the chassis until the handle disengages the drive connector from the backplane connector (see Figure 3-14C).
Note: If you will have only one disk drive, it should be located in the bottom–most slot. Carefully slide the drive out of the bay (see Figure 3-14D) and gently place it on a flat ESD-safe surface. (Do not use the handle to pull the drive out of the bay.)
If you are replacing the disk drive, proceed to “Installing a Disk Drive”, for installation instructions. (After you have replaced the disk drive, return to step 8 for instructions to power on your system.) If you are not replacing the disk drive, proceed to the next step.
Close the bezel door.
Power on the system.
Memory is contained on cards that are referred to as DIMMs (dual inline memory modules). Each workstation enclosure can contain two, four, six, or eight DIMMs. The DIMMs are installed in eight slots located on the system node board.
These eight DIMM slots are organized into a group of even–numbered slots 0, 2, 4, and 6 and a group of odd-numbered slots 1, 3, 5, and 7, as shown in Figure 3-15.
DIMMs are installed one per DIMM slot, and two at a time, so that the two DIMMs installed provide local memory for the same pair of banks. For example, you can install a DIMM in slot 0 and another in slot 1 (this adds memory to bank pairs 0 and 1). Table 3-1 lists the DIMM slots and the corresponding bank pairs to which local memory is provided when DIMMs are installed:
Table 3-1. DIMMs and Bank Pairs
DIMM in Slot Number | Provides Local Memory for Bank Pair Numbers |
|---|---|
0[a] | 0 and 1 |
1 | 0 and 1 |
2 | 2 and 3 |
3 | 2 and 3 |
4 | 4 and 5 |
5 | 4 and 5 |
6 | 6 and 7 |
7 | 6 and 7 |
[a] The first two DIMMs must be installed in DIMM slot 0 and DIMM slot 1. | |
When installing DIMMs, you must follow these guidelines:
Memory is increased or decreased in two-DIMM increments only.
The two DIMMs that make up a bank pair must be the same memory size; however, each pair of DIMMs can be a different memory size from another pair.
The first two DIMMs must be installed in DIMM slot 0 and DIMM slot 1. Subsequent DIMM pairs can be installed in any order, but for consistency they should be installed in the next available DIMM slots.
The DIMMs used in the rack-mountable workstation are not compatible with the DIMMs used in Origin 200, SGI 2000 series, Onyx2, or Octane systems.
The workstation supports the following memory kits:
512-MB kit with integrated directory memory.
1-GB kit with integrated directory memory.
2-GB kit with integrated directory memory.
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.
