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.
To access and remove/replace internal system components, power off the system as described in “Powering the System On and Off” in Chapter 2, and then use the follow these steps:
Unfasten the two screws that hold the module to the front of the rack.
Disconnect all cables from the rear of the module.
Carefully slide it forward out of the rack until it is stopped by the safety latches.
If removing, adding, or replacing a PCI/PCI-X card, follow the additional steps in “Installing and Removing PCI and PCI–X Cards”.
Remove the ten Phillips screws as shown in Figure 7-1 and lift the hinged cover.
Follow the instructions in this chapter for adding/removing the internal components, such as PCI cards or memory DIMMs.
After completing the procedure(s) needed, close and secure the module by replacing the cover and tightening the ten screws, as shown in Figure 7-2.
Slide the module back into the rack and secure it at the front of the rack with the two screws you removed in step 1.
Move to the back of the rack and reconnect all cables to the rear of the unit before powering on the system.
Your system module and various optional modules in your system support PCI and PCI–X cards. The following instructions, which describe how to install and remove a PCI or PCI–X card in the Onyx base 350 module, can be used to install PCI and PCI–X cards onto other modules in your system. Figure 7-3 shows the location of the PCI and PCI–X card slots in the module. Note that these instructions do not cover the optional 4U PCI module.
For an updated list of supported PCI and PCI–X cards, see SGI Supportfolio Online at: http://support.sgi.com.
This section explains how to perform the following procedures:
Installing a new card
Removing/replacing a card
To install a PCI or PCI–X card, follow these steps:
Power off the module. For instructions on how to power off the module, see “Powering the System On and Off” in Chapter 2.
Complete the first three steps in “Removing a Module and Accessing Internal Components”.
Warning: Components may be hot. To avoid injury, allow the components to cool for approximately five minutes before you proceed with these instructions. If you are installing a card in one of the two lowermost card slots, you must also remove the module completely from the rack and remove its left-side rail and lower support bracket Otherwise, go on to step 6.
Using two people, depress the locking latches on either side of the module and pull the unit out completely (see Figure 7-4).
Move the module to a sturdy table or other non-static work surface.
Remove the chassis side rail by unscrewing the five Phillips screws, as shown in Figure 6-3.
Caution: Depending on the type, the module may or may not have a factory-installed IO9 card, which always comes installed in the lowermost slot. To prevent damage to your system, only a trained SGI service support engineer can install or remove an IO9 card. Remove the lower PCI/PCI–X support bracket that covers the two lowermost slots, as shown in Figure 7-6, by removing the four Phillips screws.
To add a new card to the module, follow these steps:
Remove the blanking plate retention screw (see Figure 7-7).
Extract the blanking plate from the chassis.
To remove and replace a PCI card from a module, undo the retaining screw holding the card in place and extract it, as shown in Figure 7-8.
To replace the card you removed, carefully insert it into the slot and screw in the retention screw, as shown in Figure 7-9. If you are not replacing the card you have removed, proceed to the next step.
If you have removed a card from one of the upper three slots (and will not be replacing it with another) place a blanking plate to cover the slot and screw in the retaining screw, as shown in Figure 7-10.
If you removed or installed a card in one of the two bottom–most card slots, complete the following two substeps. Otherwise, proceed to step 11.
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 7-11.
Reattach the chassis side rail using the five screws you removed (see Figure 7-5).
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 had removed to secure the cover, as shown in Figure 7-2.
Using two people, slide the module back into the rack.
Install the two screws that secure the module to the front rails of the rack.
Install all of the cables at the rear of the module.
Power on the system. For instructions on how to power on, see “Powering the System On and Off” in Chapter 2.
Each Onyx 350 base compute module can contain one or two sled-mounted Ultra3 SCSI disk drives (see Figure 7-12).
| Note: A system expansion compute module may or may not contain disk drives. These modules require an optional IO9 PCI card in order to support SCSI 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.
With the locking handle fully swung open, gently push the drive into the bay until the locking handle engages with the left side of the bay opening, as shown in Figure 7-13A.
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 7-13B and Figure 7-13C.
Close the bezel door as shown in Figure 7-13D.
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 module, as follows:
To power off the module indicated at the L1 prompt (001c01-L1, for example), enter the following command. (If you want to power off the peer-attached module, proceed to the next step.)
001c01-L1> power down
To power off the module that is connected to the module indicated at the L1 prompt (001c01-L1, for example), enter the following command:
001c01-L1> ctc power down
Open the bezel door located on the left side of the front panel of the module, as shown in Figure 7-14A. (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 7-14B) and swing open the locking handle away from the chassis until the handle disengages the drive connector from the backplane connector
(see Figure 7-14C).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 (refer to Figure 7-14D) 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 module.) If you are not replacing the disk drive, proceed to the next step.
Close the bezel door.
Power on the module, as follows:
To power on the module indicated at the L1 prompt (001c01-L1, for example), enter the following command. (If you want to power on the peer-attached module, proceed to the next step.)
001c01-L1> power up
To power on the module that is connected to the module indicated at the L1 prompt (001c01-L1, for example), enter the following command:
001c01-L1> ctc power up
Memory is contained on cards that are referred to as DIMMs (dual inline memory modules). Each Onyx 350 system expansion compute module or MPX module can contain two, four, six, or eight DIMMs installed on eight DIMM slots located on the module.
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 7-15.
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 7-1 lists the DIMM slots and the corresponding bank pairs to which local memory is provided when DIMMs are installed:
Table 7-1. 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. | |
You must follow these guidelines when installing DIMMs:
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 differ in memory size from another pair.
The first two DIMMs must be installed in DIMM slot 0 and DIMM slot 1. Subsequent DIMMs can be installed into any bank pairs as long as the two DIMMs are installed so that they provide local memory for the same bank pair. For example, you can install a DIMM in slot 2 and a DIMM in slot 3 to provide local memory for banks 2 and 3, install DIMMs in slots 4 and 5 to provide memory for banks 4 and 5, or install DIMMs in slots 6 and 7 to provide memory for banks 6 and 7.
Note: The DIMMs used in the Onyx 350 module, the system expansion compute module, and the MPX module, are not compatible with the DIMMs used in Origin 200, SGI Origin 2000 series, Onyx2, O2, or Octane systems. The Onyx 350 system supports the following memory kits:
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.

Each Onyx 350, compute, compute/graphics, or MPX module can contain one or two sled-mounted power supplies (see Figure 7-26). The second is an optional supply.
Use the LED located on the front (towards the top) of the power supply to read the condition of the power supply. Table 7-2 shows the LED status and the power supply condition it indicates.
Table 7-2. Power Supply LED Status and Condition
LED Status | Power Supply Condition Indicated |
|---|---|
Off | If your system has one power supply, it indicates that the power supply is not receiving AC power. If your system has two power supplies, the LED on both power supplies would be Off, and it would indicate that both power supplies are not receiving AC power. Power supplies will not be receiving AC power because either the module is not plugged into power, or an electrical fuse has blown. |
Amber | This indicates a fault condition for one of the following reasons: - The temperature limit has been exceeded. - The current limit has been exceeded. |
Blinking green | The power supply is receiving AC power, but the primary DC power has not yet activated. |
