Most of the procedures in this chapter require the removal of the top cover to access the internal component(s) you are removing or replacing. Use the following steps and illustrations to open and close the cover:
To remove the module's top cover and access the internal system components, remove the ten Phillips screws as shown in Figure 7-1.
Lift the hinged cover into the fully open position.
Close the hinged cover on the system and screw in the ten Phillips screws to secure the cover, as shown in Figure 7-2.
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 from system base compute module, can be used to install and remove PCI and PCI–X cards from the expansion compute module or a compute, memory and PCI expansion (CMPX) module.
Figure 7-3 shows the location of the PCI and PCI–X card slots in the base compute module. An optional IO9 base I/O card is shown in the illustration.
For an updated list of supported PCI and PCI-X cards, see SGI Supportfolio at http://support.sgi.com .
This section describes the following:
When installing or removing PCI or PCI–X cards from your system, be aware of the following rules:
If you run a PCI and PCI–X cards on the same bus at the same time, the PCI–X card will run on PCI mode.
If you run cards of different speeds on the same bus, the highest-speed card will run at the speed of the slower card. For example, if a card is running at 100 MHz in one slot of a bus and a card is running at 33 MHz on the second slot of the same bus, both cards will run at 33 MHz.
When deciding to install a PCI or PCI–X card, be aware that if a base I/O card (a PCI card that runs at 66 MHz) is installed in your module (in slot 1 of bus1), and if you want to install a card in slot 2 of bus 1, (the slot immediately above where the IO10 or IO9 base I/O card is installed), the slot will operate only in PCI mode at a speed no faster than 66 MHz.
The base I/O card is installed/replaced by trained service personnel only.
Note the following caution when installing or removing a card:
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.
To install a PCI or PCI–X card, follow these steps:
Power off the server system. For power off instructions, see “Powering the System On and Off” 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. If your module is rackmounted, remove the two screws that secure the module to the front rails of the rack. If the module is mounted with shelf rails, remove the screws at the rear. If your module is not rackmounted, proceed to step 5.
If the module is mounted with the optional slide rail kit, pull the module from the rack until it is stopped by the safety latches. Otherwise, two people should lift the unit from the rack and place it on a stable work surface.
Open the top cover as described in “Accessing the System's Internal Components”.
If you are installing a card into the top two PCI/PCI–X slots, you can install it without completely removing the module from the rack (optional slide rails only).
Note: If you are removing a card from one of the two lower slots (bus 1, slot 1, or bus 1, slot 2), you must remove the module from the rack. For instructions, see “Removing a Module on Slide Rails from a Rack” in Chapter 1. Make sure that you read “Safety Instructions ”, and “Rules for Card Installation and Removal” before beginning your card installation.
If you are installing a card in one of the two bottommost card slots, you may also need to remove the optional chassis rail by unscrewing the five Phillips screws, as shown in Figure 7-4. (If you are not installing a card into one of the bottom-most card slots or your module is not slide-rail mounted, proceed to step 9.)
Caution: The module may or may not have a factory-installed base I/O 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 a base I/O card. If you are installing a card in one of the two lowermost card slots, you must remove the lower PCI/PCI–X support bracket that covers the two lowermost slots, as shown in Figure 7-5, 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 7-6, and the blanking plate.
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 7-7. If you have installed the card into one of the upper two slots, proceed to step 13.
If you have installed a card in one of the two bottommost card slots, replace the lower PCI/PCI–X support bracket that covers the two bottommost slots and screw in the four Phillips screws, as shown in Figure 7-8.
Replace the optional chassis rail (if applicable) by screwing in the five Phillips screws, as shown in Figure 7-9.
If you removed the module from the rack, perform the following substeps. (If you have not removed the module from the rack, proceed to step 15.)
Fully extend the left and right slide rails from the rack until they lock into place.
This step requires two people. With one person holding each side of the module, align the chassis rails of the module with the slide rails of the rack.
Slide the chassis rails into the slide rails until the chassis rails are stopped by the safety latches.
Press the safety latches on both sides of the module and slide the module into the rack.
Install the two screws that secure the module to the front rails of the rack. For shelf mounted units, install the two screws at the rear of the module.
Install all of the cables at the rear of the module.
Power on the server system. For power on instructions, see “Powering the System On and Off” in Chapter 1.

Warning: Components may be hot. To avoid injury, allow the components to cool for approximately five minutes before you proceed with these instructions. Remove the two screws that secure the module to the front rails of the rack.
Pull the module from the rack until it is stopped by the safety latches.
Note: If you are removing a PCI or PCI–X card from one of the two lower slots (bus 1, slot 1, or bus 1, slot 2), you must remove the module from the rack. For instructions, see “Removing a Module on Slide Rails from a Rack” in Chapter 1. Make sure that you read “Safety Instructions ”, and “Rules for Card Installation and Removal”, before installing the card.
To access the card, remove the ten Phillips screws, as shown in Figure 7-10, and lift the hinged cover.
If you are removing a card from one of the two lowermost card slots and your system uses optional slide rails, remove the chassis rail, by unscrewing the five Phillips screws as shown in Figure 7-11. (If you are not removing a PCI/PCI–X card from one of the two lowermost card slots, proceed to step 9.)
Caution: Only a trained SGI service support engineer can install and remove a base I/O card. Otherwise, your system could be damaged. Therefore, if a base I/O card is installed in your system (it is always installed in the lowermost slot), you can remove a card only from the upper three slots. If you are removing a card from one of the two lowermost slots, you must also remove the lower PCI/PCI–X support bracket that covers the two lowermost slots by unscrewing the four Phillips screws, as shown in Figure 7-12.
Unscrew the retaining screw from the card that you will remove, and extract the card, as shown in Figure 7-13. Place the card on an ESD-safe surface.
If you are replacing the card that you have removed, reference the instructions in “Installing a PCI or PCI-X Card”. If you are not replacing the card that you have removed, proceed to the next step.
Place a blanking plate to cover the slot where you removed the card, and screw in the retaining screw, as shown in Figure 7-14. After installing the blanking plate, if you have removed a card from one of the two lowermost slots, proceed to the next step. Otherwise, proceed to step 14.
If you have removed a card from one of the two bottommost card slots, replace the lower PCI/PCI–X support bracket that covers the two bottommost slots, and screw in the four Phillips screws, as shown in Figure 7-15.
Replace the optional chassis rail (if applicable), by attaching the five Phillips screws, as shown in Figure 7-16.
Close the hinged cover on the system and screw in the ten Phillips screws to secure the cover, as shown in Figure 7-17.
If your system uses optional slide rails and you removed the module from the rack, follow these substeps. (If you have not removed the module from the rack, proceed to step 16.)
Fully extend the left and right slide rails from the rack until they lock into place.
This step requires two people. With one person holding each side of the module, align the chassis rails of the module with the slide rails of the rack.
Slide the chassis rails into the slide rails until the chassis rails are stopped by the safety latches.
Press the safety latches on both sides of the module, and slide the module into the rack.
For modules mounted on shelf rails, use two people to slide the unit into the rack.
Install the two screws that secure the module to the front rails of the rack. For shelf mounted units, secure the two screws at the back.
Install all of the cables at the rear of the module.
Power on the server system. For powering on instructions, see “Powering the System On and Off” in Chapter 1.
Each base compute module contains one or two sled-mounted hard disk drives (see Figure 7-18).
| Note: A CMPX module may or may not contain disk drives. These modules would require a base I/O PCI card in order to have a disk drive(s). |
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 the drive into the bay until the locking handle engages with left side of the bay opening, as shown in Figure 7-19A.
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 7-19B and Figure 7-19C.
Close the bezel door, as shown in Figure 7-19D.
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 power off the server system. For instructions to power off the server system, see “Powering the System On and Off” in Chapter 1.
Open the bezel door located on the left side of the front panel of the module, as shown in Figure 7-20A. (Make sure that you open the door as far as it will open.)
Remove the drive by depressing the locking handle with your forefinger (Figure 7-20B). Then swing open the locking handle away from the chassis until the handle disengages the drive connector from the backplane connector (see Figure 7-20C).
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 7-20D) 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”. (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 server system as described in “Powering the System On and Off” in Chapter 1.
Each Altix 350 server system compute module and CMPX module can contain one or two sled-mounted power supplies (refer to Figure 7-21). The second is a redundant power supply to assure that your system always has power.
This section provides the following information:
Use the LED located on the front (towards the top) of the power supply to read the condition of the power supply. Table 7-1 shows the LED status and the power supply condition the LED status indicates.
Table 7-1. LED Status and Power Supply 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 a electrical fuse has blown. |
Amber | 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 main primary DC power has not yet activated. |
Green | The power supply is operating properly. |
To replace a power supply, follow these steps:
If you are replacing a power supply in a module that has only one power supply (no redundant power supply), power off the server system as described in the “Powering the System On and Off” in Chapter 1. If you are replacing a redundant power supply, you do not have to power off your server system to replace the power supply.
Remove the power supply to be replaced, as follows:
Swing open the bezel door located on the right side of the module front panel. With a Phillips screw driver, unscrew the two screws on the screen cover as shown in Figure 7-22A.
Swing open the screen cover as shown in Figure 7-22B.
Disengage the power supply from the power supply bay by pushing the interior release button to the right and pulling up and out on the green–colored handle lock as shown in Figure 7-22C.
Gently pull out the power supply from the chassis until it clears the power supply bay as shown in Figure 7-22D. Place the power supply on an ESD-safe surface.
Caution: When pulling out the power supply from the chassis, make sure not to disturb the power supply fan's ribbon cable.
Install the replacement power supply, as follows:
Position the power supply in the slot and with the power supply handle pulled up (fully opened), gently push the power supply into the bay as shown in Figure 7-23A.
Caution: When installing the power supply, make sure that the power supply does not clip or pinch the power supply fan's ribbon cable. Push in and down on the green–colored handle and snap the power supply into place as shown in Figure 7-23B.
After you have installed the power supply, swing the screen cover until it closes as shown in Figure 6-23C.
Caution: When closing the screen cover, make sure that the cover does not clip or pinch the power supply fan's ribbon cable. Screw in the two Phillips screws that you had removed as shown in Figure 6-23D, and close the bezel door.
If you have replaced a power supply in a module that has only one power supply, power on the server system, as described in “Powering the System On and Off” in Chapter 1.
Memory is contained on cards that are referred to as DIMMs (dual inline memory modules). Each server system base compute module, system expansion compute module, and CMPX module can contain four, eight, or twelve DIMMs installed in DIMM slots located on the module.
These twelve DIMM slots are organized into three groups of (4 DIMMs each) as shown in Figure 7-24.
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, different groups of DIMMs 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 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.
The DIMMs used in the Altix 350 server system base compute module, expansion compute module, and CMPX module are not compatible with DIMMs used in the Origin 200, 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 350 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 350. 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.
To install a DIMM group, follow these steps:
Power off the server system. For powering off instructions, see “Powering the System On and Off” 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. Remove the two screws that secure the module to the front rails of the rack. For shelf-mounted modules, remove the two screws at the rear of the unit.
With shelf-mounted rails, use two people to slide the module out and move it to a stable work surface. With optional slide rails, pull the module from the rack until it is stopped by the safety latches.
To access the DIMMs, remove the ten Phillips screws shown in Figure 7-25 and lift and open the hinged cover.
Install the DIMMs, as follows (see Figure 7-26):
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”. 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.
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.
When the DIMM is fully seated in the connector, the ejector latches snap into place flush with each end of the DIMM, see Figure 7-26.
Attach the hinged cover and secure it to the module with ten Phillips screws.
If using optional slide rails, press the safety latches on both sides of the module and slide the module into the rack. For shelf-mounted units, use two people to slide the module back into the rack.
Install the two screws that secure the module to the front rails of the rack. If shelf rails are used, install the two rear screws.
Install all of the cables at the rear of the module.
