2 Installing the disk card

The procedures in this chapter describe how to install the board in your system.

Caution -

The system chassis power must be turned off, and the AC power cord must remain plugged in to ensure a proper ground.

Caution -

Handle the disk card and its disk drives gently. Sudden vibration or shock can damage one or more of the disk drives.

Caution -

Printed circuit boards and disk drives contain components sensitive to damage from electrostatic discharge (ESD) (For example, ESD can occur when you walk across a carpet and then touch the board).

Before handling the board, use an ESD strap and mat, or place your hand on a conductive surface that is grounded to a common earth ground (such as the metal card cage of the chassis) to discharge the static electricity from your body.

2.1 Powering Off the System

Note - The system might not recognize the new device unless you follow the shut down procedures in the handbook for SMCC peripherals.

1. Go to the appropriate handbook for your operating system.

Refer to the Handbook for SMCC Peripherals that came with the SPARCserver 1000 system.

2. See the section about shutting down the system, and return to this book after you perform the procedure.

Note - Do not remove the power cord from the wall outlet, or the chassis.

2.2 Inserting the disk card in the Chassis

1. Face the rear of the chassis and identify the slot in which you are installing the new disk card.

2. Remove the two screws from the filler panel covering that slot, and set the filler panel aside.

Save the screws, you will use them to secure the disk card.

3. Hold the disk card

with the component side up

This hand position provides the safest balancing grip on the heavy board.

4. Carefully insert the disk card into the slot in the chassis.

Ensure that the disk card does not slip out of the left or right card guides.

5. Ensure that the extraction levers are in the outward position as you slide the disk card toward the backplane connectors.

The board will not seat fully unless the levers are in this unlocked position.

Caution -

Do not force a board into a slot - you may damage it. The board should seat smoothly. If it binds, remove it and inspect the card cage slot for obstructions. Also inspect the board and backplane for bent pins or other damage.

6. Seat the board into the backplane connectors.

The injector/ejector levers will swing into the locked position when the backplane connectors are fully seated.

7. Install the two screws to secure the board to the card cage. See Figure 2-2

Figure 2-2 Securing the disk card to the Chassis

Repeat the steps in this section for each disk card that you install.

2.3 Connecting the SCSI Data Cable and Terminator

The procedure for connecting the data cable and the terminator for each type of disk card is different. See the appropriate section below. For information on configuration options, see Appendix A.

2.3.1 The 2.1 Gbyte disk card

1. Connect the SCSI data cable from the SCSI IN port on the disk card to either the on-board SCSI port in the system board or to the FSBE card.

In a single system board configuration (one system board in slot 0), you must install and use an FSBE card. The on-board SCSI port in the system board installed in slot 0 must be terminated.

In a system configuration of two or more system boards, use the on-board SCSI port of one of the other system boards (see Appendix A).

2. Connect a 50-pin SCSI terminator to the SCSI OUT port on each 2.1-Gbyte disk card.

This terminates the SCSI chain.

Note - Every 2.1-Gbyte disk card must have a terminator connected to the SCSI OUT port.

2.3.2 The 4.2 Gbyte disk card

1. Connect the SCSI data cable from the SCSI IN port on the disk card to the SWIS/S card.

2. If you are daisy-chaining two or more disk cards, connect a 68-pin single-ended SCSI terminator to the SCSI OUT port on the last disk card in the chain. See "Daisy-chaining disk cards" on page 1-2.

If you are installing a single 4.2 Gbyte disk card, connect the SCSI terminator to the SCSI OUT port on the disk card.

Note - You can daisy-chain up to three 4.2 Gbyte disk cards.
To avoid SCSI addressing conflicts, disk cards in slot 0 and slot 2 in the disk tower 1000 must not be on the same chain.

Note - Each wide SCSI daisy chain must not exceed 6.0 meters in total length. This is the sum of:
o The length of all cables, including the internal length of cable connectors
o The internal length of all disk cards in the chain
(length per card is 51 inches (1.3 meters))
o The internal length of the SWIS/S card (3.9 inches (0.1 meters))

2.4 Checking Connections

Before restarting your system:

Check that SCSI terminators are correctly attached to the SCSI OUT port on the following:

System board in slot 0

All 2.1 Gbyte disk cards

All 4.2 Gbyte disk cards at the end of each SCSI chain

Make sure that the disk card extraction levers are fully closed. Use your thumbs and press in on each board near the extraction levers.

Check that all cables are connected and secure. Even connections you did not change may have come loose during the installation or removal process.

2.5 Verifying Connection (Optional)

Refer to the chapter that discusses powering the server on and off in the SPARCserver 1000 System Service Manual, part number 801-2895-xx.

To verify that the newly-installed disk card is installed correctly:

1. Turn on power to the monitor.

If the system does not have a monitor, refer to your system service manual for information on attaching an RS232C terminal.

2. Turn the key switch, located on the front panel of the SPARCserver 1000 system, to the

Allow the system to boot.

3. Refer to the

4. At the

---------------------

ok probe-scsi-all 

---------------------

The OpenBoot firmware provides the probe-scsi-all command to check all available SCSI devices. Watch the monitor and verify that the diagnostic shows the newly-added disk drives.

Note - If the SPARCserver 1000 system does not recognize one or more disk drives (new or old), contact your service representative.

5. When the system displays the

---------------

ok boot -r

When the system finishes booting, it should display the login prompt (hostname%). At this point, log in and continue operation.
