The 8-bay storage expansion option kit contains the following parts: Dual-channel single-ended UltraSCSI controller PCI card 8-slot UltraSCSI backplane 2 · I C cable 8-slot UltraSCSI power cable 8-slot UltraSCSI data cable The dual-channel UltraSCSI controller card may be installed in any available PCI slot. For maximum performance, the system should be configured, if possible, with no more than one dual-channel UltraSCSI host adapter on each PCI bus. For additional information on PCI buses and cards, see "About Peripheral Component Interconnect (PCI) Buses" on page 58. The dual-channel UltraSCSI PCI host adapter card supplied with the 8-bay storage expansion option has two internal SCSI connectors and two external SCSI connectors. When installed as part of the 8-bay storage expansion option, only the internal connectors are used. Do not connect external SCSI devices to a SCSI channel that is used to support internal disk drives. Additional single-ended and differential UltraSCSI host adapters are available for controlling external SCSI storage devices. If you are installing two 8-bay storage expansion option kits, install the controller card for the upper 8-slot backplane in a PCI slot located above the controller card used for the lower 8-slot backplane. If you are installing two 8-bay storage expansion option kits at this time, it is easier to perform each step twice as you follow the procedure, rather than repeat the entire procedure to install the second option kit. Insert the lower 8-slot backplane before inserting the upper 8-slot backplane. Before You Begin Complete these tasks: "How to Power Off the System" on page 26 "How to Remove the Right Side Panel" on page 32 "How to Remove the Left Side Panel" on page 36 "How to Avoid Electrostatic Discharge" on page 40 "How to Remove the Disk Fan Tray Assembly" on page 210 What to Do 1.Remove the filler panel for the PCI slot you intend to use. a. Remove the Phillips screw that secures the PCI filler panel to the rear panel. b. Pull out the filler panel. View Image 2.Insert the PCI card into the appropriate slot on the main logic board. a. Align the left side of the card with the appropriate opening on the rear panel. b. Push the card into the corresponding slot on the main logic board. 3.Secure the PCI card faceplate to the rear panel with the Phillips screw. 4.On the right side of the enclosure, remove the two screws that secure the 8-slot backplane filler panel to the disk cage, and remove the filler panel. Remove both backplane filler panels if you are installing the lower 8-slot backplane. 5.Insert the 8-slot UltraSCSI backplane down into the 12 mounting hooks at the rear of the disk cage. Use the lowest available set of hooks; do not mount a backplane at the top of the disk cage if the center portion of the cage has no backplane. View Image 6.Secure the backplane to the disk cage using the two Phillips screws provided in the option kit. 7.2 7. Connect the I C cable. 2 If you are installing the lower 8-slot backplane, connect the I C cable between connector P0500 on the 4-slot backplane and connector P0600 on the 8-slot backplane. View Image 2 If you are installing the upper 8-slot backplane, connect the I C cable between connector P0601 on the lower 8-slot backplane and connector P0600 on the upper 8-slot backplane. View Image 8.Connect the 8-slot UltraSCSI power cable to the backplane at connector J0101. Make sure that the tab on the bottom of the connector snaps into place. View Image 9.Connect the other end of the 8-slot UltraSCSI power cable to the power distribution board. If you are installing the lower 8-slot backplane, use connector J0303 on the power distribution board. If you are installing the upper 8-slot backplane, use connector J0304 on the power distribution board. Be sure that the tab on the right side of the connector snaps into place. 10.Remove the three small Phillips screws that secure the cable access panel to the top of the system chassis. View Image 11.Tilt the front edge of the access panel upward and lift it free from the chassis. 12.Insert the 8-slot UltraSCSI data cable into the cable access port on the top of the system chassis. Position the cable in the access port with connectors P2-A and P2-B toward the left side of the enclosure (where the main logic board is located). If you are installing the upper 8-slot backplane, you must position the cable between the two existing data cables in the access port. 13.On the left side of the enclosure, carefully route the cable so that it rests on top of the shelf located directly above the top CPU module. Take care to avoid damaging the cable on any sharp sheet metal edges. 14.On the left side of the enclosure, connect the two cable connectors to the associated UltraSCSI controller PCI card. Connect P2-A to the connector closest to the rear panel, and P2-B to the connector closest to the front of the card. If you are installing two expansion option kits, the UltraSCSI data cable on the outside (on top in the access port) must connect to the PCI card in the lower slot. 15.If the 8-slot UltraSCSI data cable has excess slack, carefully fold the cable and secure the fold using the cable clip attached to the CPU card cage. Do not crease the cable when you fold it. 16.Connect the other end of the cable to the 8-slot backplane. Connect P1-B to the upper connector, J0402, and connect P1-A to the lower connector, J0102. If you are installing two expansion option kits, the UltraSCSI data cable on the outside (on top in the access port) must connect to the lower 8-slot backplane. View Image 17.If the 8-slot UltraSCSI data cable has excess slack, carefully fold the cable and secure the fold using the cable clip attached to the disk fan tray assembly. Do not crease the cable when you fold it. 18.Replace the cable access panel on top of the system chassis. Align the three tabs on the edge of the panel with the corresponding slots in the system chassis. 19.Secure the access panel with the three Phillips screws. 20.Fill in information on the four labels at the ends of the 8-slot UltraSCSI data cable. This identification is important when replacing a cable, backplane, or PCI card, particularly when two 8-bay storage expansion options are installed. a. On the left side of the system, fill in the two labels on the 8-slot UltraSCSI data cable for connectors P2-A and P2-B. Fill in the number of the PCI slot used and check the box to indicate either the upper backplane or lower backplane. b. On the right side of the system, fill in the two labels on the 8-slot UltraSCSI data cable for connectors P1-A and P1-B. Check the box to indicate either the upper backplane or lower backplane. Note - After reassembling the system, be sure to perform the steps in the following section to reconfigure and reboot your system so that it can use the 8-bay storage expansion option. What Next Complete these tasks to reassemble the system: "How to Install the Disk Fan Tray Assembly" on page 212 "How to Install the Left Side Panel" on page 38 "How to Install the Right Side Panel" on page 34 To install disk drives for the new backplane(s), complete this task: "How to Install a Disk Drive" on page 186 Before the system can properly recognize the new UltraSCSI controller card(s), you must perform the following procedure: 1.Power on the system. See "How to Power On the System" on page 28. 2.When the system banner is displayed on the monitor, immediately enter the Stop-a sequence on the Sun keyboard. If you are using an alphanumeric terminal instead of a monitor, press the Break key on the terminal's keyboard. 3.When the ok prompt is displayed, enter the following command: ok setenv disk-led-assoc 0 x y where: x is an integer between 1 and 10 identifying the PCI slot number where the lower UltraSCSI controller is installed y is an integer between 1 and 10 identifying the PCI slot number where the upper UltraSCSI controller is installed For example, if the controller cards are installed in PCI slots 5 and 7, enter the following: ok setenv disk-led-assoc 0 5 7 For a system with only one controller card installed in PCI slot 2, enter the following: ok setenv disk-led-assoc 0 2 4.Enter the following command at the ok prompt: ok reset 5.When the system banner is displayed on the monitor, immediately enter the Stop-a sequence on the Sun keyboard. If you are using an alphanumeric terminal instead of a monitor, press the Break key on the terminal's keyboard. 6.Enter the following command to perform a reconfiguration boot: ok boot -r This command rebuilds the device trees for the system, incorporating any newly installed options so that they can be recognized by the system. After the reconfiguration boot has successfully completed, the system prompt should be displayed. Next Topic
