This chapter provides information about installing or removing components from your SGI system, as follows:
This section describes how to open the system for maintenance and upgrade, protect the components from static damage, and return the system to operation. The following topics are covered:
To prepare the system for maintenance, follow these steps:
If you are logged on to the system, log out.
At your system console, switch to the L1 mode by entering the following command: $> Ctrl+T From the L1 prompt (L1>), power off the system with the following command: L1> power down
Locate the PDU(s) in the rear of the rack and turn off the circuit breaker switches on each PDU.
When you finish installing or removing components, return the system to operation as follows:
Turn each of the circuit breaker switches to the “on” position.
At your system console, enter the following command:
L1> power up
Verify that the LEDs turn on and illuminate green and that your controllers display that the system is powered on for each segment of the procedure, which indicates that the power-on procedure is proceeding properly.
If your system does not boot correctly, see “Troubleshooting Chart” in Chapter 13, for troubleshooting procedures.
 | Caution: The components inside the system are extremely sensitive to static electricity. Always wear a wrist strap when you work with parts inside your system. |
To use the wrist strap, follow these steps:
Unroll the first two folds of the band.
Wrap the exposed adhesive side firmly around your wrist, unroll the rest of the band, and then peel the liner from the copper foil at the opposite end.
Attach the copper foil to an exposed electrical ground, such as a metal part of the chassis.
Caution: Do not attempt to install or remove components that are not listed in Table 12-1. Components not listed must be installed or removed by a qualified SGI field engineer.
Table 12-1 lists the customer-replaceable components and the page on which you can find the instructions for installing or removing the component.

This section provides instructions for adding or replacing a PCI or PCI–X card in the IX-brick or PX–brick. To maximize the operating efficiency of your cards, be sure to read all the introductory matter in the “PCI and PCI–X Card Configuration Guidelines” in Chapter 7 before beginning the installation.
| Caution: To protect the PCI cards from ESD damage, SGI recommends that you use a grounding wrist strap while installing a PCI card. |
To add or replace a PCI card, follow these steps:
Shut down the operating system. (See your software guide if you need instructions to do this.)
Power off the I/O brick by following the power-off instructions in the “Powering Off the System” in Chapter 1.
To extract it from the slot, pull the handle on the selected card carrier straight out, as shown in Figure 12-1.
If you are replacing a card, gently remove the existing card from the carrier.
If you are adding a card, extract the carrier metal filler plate by pushing down on it, as shown in Figure 12-2. This filler plate covers the area where your card connectors will protrude out to the rear panel of the I/O brick.
Note: If you are adding or replacing a half-height PCI card, skip step 5 and proceed to step 6. If the full-height card that you want to install does not fit in the carrier, follow these steps:
Loosen the three screws on the guide bar with a Phillips screwdriver (if your carrier uses T8 Torx screws, you will need a Torx screw driver).
Adjust the carrier guide bar (also known as the alignment rail) up or down as necessary (see Figure 12-3).
Mount the card in the carrier, as shown in Figure 12-4, so that the following occurs:
– The card connectors protrude through the bulkhead where the metal filler plate was located.
– The edge connectors fit between the bottom guides of the carrier.
– The top of the card fits under the clips on the guide bar.
Tighten the three screws on the guide bar. Then skip step 6 and proceed to
step 7.
To install a half-height PCI card in a carrier, follow these steps:
Remove the two screws from the carrier guide bar, as shown in Figure 12-5.
Note: Take care not to lose the threaded inserts in the carrier guide bar. Loosen the third screw of the carrier guide bar.
Place the half-height PCI card in the carrier so that the connector edge of the card rests against the lower guide tab of the carrier (see Figure 12-5).
Move the carrier guide bar (adjustment rail) so that it holds the card firmly in place (see Figure 12-6).
Place the PCI card bracket so that the screw holes of the bracket align with the empty screw holes of the carrier guide bar, as shown in Figure 12-7.
Secure the bracket to the carrier guide bar with two T8 Torx screws.
Tighten the screw that you loosened in step 6b.
Insert the carrier-mounted PCI card into the vacant slot, using the slot guide, as shown in Figure 12-8.
Push horizontally on the carrier seating bar, as shown in Figure 12-9, to seat the card securely in the slot.
Power on the I/O brick by following the power-on instructions in the “Powering On the System” in Chapter 1.
Boot your operating system software. (See your software operation guide if you need instructions to boot your operating system.)
Run the hinv hardware inventory command to verify the installation. This command lists hardware that the operating system discovered during the boot operation.
The IX-brick has two system disk drive bays as shown in Figure 12-10. This section describes how to install or remove the drives.
Before you install a disk drive, you must power off the IX-brick according to the instructions in the “Powering Off the System” in Chapter 1.
| Caution: To protect the system from ESD damage, SGI recommends that you use a grounding wrist strap while installing the disk drive. |
To install a disk drive, see Figure 12-11 and follow these steps:
Remove the drive bay cover to access the two disk drive bays (see panel 1 in Figure 12-11).
Note: If you are installing only one disk drive, install it in the rightmost bay. Position the drive assembly so that it engages the bay guide rails, and then gently push the drive into the bay. Do not use the locking handle to push the drive into the bay.
Swing the locking handle towards the chassis until the locking handle engages the latch.
Snap on the drive bay cover.
After you finish installing the disk drive, power on the IX-brick according to the instructions in the “Powering On the System” in Chapter 1.
Before you remove a disk drive, you must power off the IX-brick according to the instructions in the “Powering Off the System” in Chapter 1.
To remove a disk drive, follow these steps (see Figure 12-12):
Remove the drive bay cover to access the two disk drive bays, as shown in panel 1 of Figure 12-12.
Remove the disk drive by depressing its handle lock with your thumb and pulling the handle away from the chassis until the handle disengages the disk drive connector from the backplane connector.
Carefully slide the disk drive out of the bay and place it on an ESD-safe surface. Do not use the handle to pull the disk drive out of the bay.
Note: When the IX-brick has only one disk drive installed, it should reside in the rightmost bay. Install the drive bay cover.
After you remove the disk drive, power on the IX-brick according to the instructions in the “Powering On the System” in Chapter 1.
| Caution: Follow electrostatic discharge (ESD) precautions while replacing the drive carriers. Avoid contact with the backplane components and module connectors. |
To remove and replace a drive carrier module from the SGI TP900 enclosure, follow these steps:
| Caution: Do not remove a drive carrier unless a replacement or a dummy carrier can be immediately added. The system must not be run without all modules in place. Any unused drive bays must be fitted with a dummy carrier module. |
Spin down the drive prior to removal, using the operating system.
Caution: Damage can occur to a drive if it is removed while still spinning. If you cannot use the operating system to spin down the drives prior to removal, perform all steps of the following procedure to ensure that the drive has stopped prior to removal. Note: The anti-tamper lock must be off. If the drive module is locked, insert the Torx screwdriver (included with the disk drive) into the socket in the lower part of the handle trim. Then turn it 90 degrees counterclockwise until the indicator visible in the center aperture of the handle shows black. See Figure 12-13. Release the carrier handle by pressing the latch in the handle towards the right.
Gently withdraw the drive carrier module approximately 1 inch (25 mm), and then wait 30 seconds for the drive to spin down.
After 30 seconds, withdraw the module from the drive bay.
Release the handle of the replacement carrier by pressing the latch in the handle towards the right, as shown in Figure 12-14. Insert the carrier into the enclosure.
Important: Ensure that the carrier is oriented so that the drive is uppermost and the handle opens from the left. Gently slide the carrier all the way into the enclosure until it is stopped by the camming lever on the right of the carrier, as shown in Figure 12-15.
Push the carrier handle into place—the camming foot on the base of the carrier will engage in a slot in the enclosure. Continue to push firmly until the handle fully engages. You should hear a click as the latch engages and holds the handle closed.
This section explains how to install or replace a drive carrier in the D-brick2 storage module, as follows:
“Replacing a Drive Carrier Module ”
Caution: Do not remove a drive carrier unless a replacement or dummy carrier can be immediately added. The system must not be run without all modules in place. Any unused drive bays must be fitted with a dummy carrier module.
Note the following:
All disk drive bays must be filled with either a drive carrier module or a dummy drive module; no bay should be left completely empty.
The drives in bays 1/1 and 4/4 of the D-brick2 storage module are required for enclosure management; these bays must always be occupied.
To install a new disk drive module in the storage system, follow these steps:
Ensure that you have enough drive carrier modules and dummy modules to occupy all bays.
Carefully open the bag containing the drive carrier module.
Warning: The disk drive handle might have become unlatched in shipment and might spring open when you open the bag. As you open the bag, keep it a safe distance from your face. Place the drive carrier module on an antistatic work surface and ensure that the anti-tamper lock is disengaged (unlocked). The indicator window is red when the drive is locked. A disk drive module cannot be installed if its anti-tamper lock is activated (locked) outside the enclosure.
Drives are shipped with their locks set in the unlocked position. However, if a drive is locked, insert the Torx screwdriver (included with the disk drive) into the socket in the lower part of the handle trim and turn it 90 degrees counterclockwise until the indicator visible in the center aperture of the handle shows black. See Figure 12-16.
Open the handle of the replacement carrier by pressing the latch handle towards the right (see Figure 12-17).
Remove the dummy drive carrier module from the target drive bay.
Orient the new drive carrier module so that the hinge of the handle is on the right. Then slide the drive carrier module into the chassis until it is stopped by the camming lever on the right of the module (see Figure 12-18).
Swing the drive handle shut and press it to seat the drive carrier module. The camming lever on the right of the module will engage with a slot in the chassis. Continue to push firmly until the handle fully engages with the module cap. You should hear a click as the latch engages and holds the handle closed.
Repeat steps 2 through 7 for all drive modules to be installed.
When you finish installing the drive carrier module(s), lock the drive carrier module(s) in the chassis by inserting the Torx screwdriver in the drive module and turning it 90 degrees clockwise. The indicator in the drive carrier module turns red when the drive is locked. See Figure 12-19.
Install dummy drive carrier modules in all empty drive bays. The drive handle and camming mechanisms operate the same as those in a standard drive carrier module.
This section explains how to replace a defective drive carrier module.
| Caution: Follow electrostatic discharge (ESD) precautions while replacing the drive carriers. Avoid contact with the backplane components and module connectors. |
| Note: Replace disk drive modules one at a time. |
To remove a drive carrier module from the D-brick2 enclosure, follow these steps:
Make sure that enough disk drives and dummy drives are available to occupy all bays.
Ensure that users are logged off of the affected systems; back up data if necessary.
If the drive module is locked, insert the Torx screwdriver into the anti-tamper lock and turn it 90 degrees counterclockwise. The indicator in the drive carrier module turns black when the drive is unlocked. See Figure 12-20.
Open the handle by pressing the latch on the module handle towards the right. Then gently slide the module out of the enclosure approximately 1 inch (25 mm), and wait 30 seconds for the drive to stop spinning. See Figure 12-21.
Caution: Damage can occur to a drive if it is removed while still spinning. After 30 seconds, withdraw the module from the drive bay. Replace it immediately; follow the instructions in “Installing a Drive Carrier Module ”.
