1.2 Basic Deﬁnitions

Figure 1-5 Enterprise 4000 System

Ultra Enterprise server systems use a centerplane. Electrical traces embedded in the centerplane serve both the front and rear sides of the centerplane; therefore, the orientation of the sockets on the rear of the centerplane is opposite the orientation of sockets on the front of the centerplane.

Boards in the front of the card cage are installed component side down, and boards in the rear of the card cage are installed component side up. Similarly, the orientation of the power/cooling modules installed in the rear of the system chassis is opposite the orientation of power/cooling modules in the front of the system chassis.

Since boards, modules, and power/cooling modules may be located on either side of the Enterprise server chassis centerplane, the terms “front,” “rear,” “right,” and “left” are defined in Table 1-1.

3.1 Handling Boards and Assemblies

Caution – The chassis AC power cord must remain connected to ensure a

! !

proper ground.

Caution – The CPU/Memory boards, modules, and cards have surface-mount components that can be broken by flexing the boards.

To minimize the amount of board flexing, observe the following precautions:

• Hold the board only by the edges near the middle of the board, where the

board stiffener is located. Do not hold the board only at the ends.

• When removing the board from an antistatic bag, keep the board vertical

until you lay it on the Sun ESD mat.

• Do not place the board on a hard surface. Use a cushioned antistatic mat.

The board connectors and components have very thin pins that bend easily.

• Do not use an oscilloscope probe on the components. The soldered pins are

easily damaged or shorted by the probe point.

• Transport the board in an antistatic bag.

• Be careful of small parts located on the component side of the board.

• Be careful not to drag boards across surfaces as board components are easily

damaged.

Caution – The heatsinks on the board can be damaged by incorrect handling.

! !

3-2 Ultra Enterprise 6000/5000/4000Systems Manual—November 1996

Do not touch the heatsinks while installing or removing the board. Hold the board only by the edges. If a heatsink is loose or broken, obtain a replacement board.

Caution – When inserting a board into slot 4 or slot 10 of a 16-slot card cage, lift the board slightly to avoid damage to the centerplane connectors.

Caution – The heatsinks on the board can be damaged by improper packaging. When storing or shipping the board, ensure that the heatsinks have sufficient protection.

3.2 Filler Panels and Load Boards

All empty board slots in Enterprise systems must have either a filler panel or a load board installed.

• Empty slots in Enterprise 5000 and 4000 systems must have a filler panel

installed. See Figure 3-1.

• Empty slots in Enterprise 6000 systems must have a load board installed.

See Figure 3-2.

Load boards and filler panels are inserted into a board slot with the springfingers facing down if inserted in the front of the system; the springfingers face up if inserted in the rear of the system.

3.3 Hot-Plug Feature

Enterprise systems have extensive error detection mechanisms, and an Automatic System Reconfiguration (ASR) feature that enables the system to be rebooted with failed components (such as CPUs, memory, or I/O) disabled. When an error is detected, the system can be reconfigured so that the board containing the failed components is placed in low power mode and is no longer accessible.

Caution – The peripheral power supply provides the precharge voltages

3-4 Ultra Enterprise 6000/5000/4000Systems Manual—November 1996

required for hot-plug. Do not attempt hot-plug of a system component if the power supply is missing or inoperative. Use prtdiag(1M)to determine the status of the peripheral power supply.

Caution – If the message: NOTICE: Hot Plug not supported in this system is displayed during boot, do NOT attempt hot-plug in this system or

damage to the hardware will occur.

The hot-plug feature enables you to insert a new board into a powered on system, despite the system being “live,” or being supplied with electrical power. When the hot-plug feature is used to add a board to a powered on system, the system will not use the new board until the system is rebooted.

3.4 CPU/Memory Boards

Each CPU/Memory board supports up to two UltraSPARC modules and 16 SIMM slots for memory.

Figure 3-3 is a simplified block diagram of the CPU/Memory board. It includes an Address Controller, 8 bit-sliced Data Controllers, a Bootbus Controller, onboard devices (including a Flash PROM, and SRAM), two CPU processor slots, and slots for two memory banks of 8 SIMMs each.

software has disabled the board. If a board has not been disabled by the ASR software, then the operating system should be halted and the system powered off prior to board removal. See Chapter 12, “Powering Off and On” and then see Section 3.4.1.2, “Removing a Board from a Nonpowered On System.”

1. Ensure that the board has been disabled by the ASR software. See Section 3.3, “Hot-Plug Feature.”

Once disabled by ASR, one of two results occurs:

• The three LEDs on the board are not lit (board has no power).

• The outer two green LEDs are not lit and the middle yellow LED is lit

(board in low power mode).

Note – System software operates such that the LED pattern described is the same for a board that is component side down (installed in front of card cage) or component side up (installed in rear of card cage).

2. Use a Phillips #1 screwdriver to mechanically release the board from the system card cage.

Insert the screwdriver into each quarter-turn access slot (the slots are located on the left and right sides of the board front panel) and then turn a quarter turn so that the arrow points to the unlocked position. See Figure 3-4.

3. If a board is not immediately replaced, a load board (Enterprise 6000 systems only) or a filler panel (Enterprise 4000 and 5000 systems only) must be installed in its place.

See Section 3.2, “Filler Panels and Load Boards.”

3.4.2 Installing a Board

3.4.2.1 Board Slot Selection

Note – Logically there is no difference between the board slots in the front or rear of the card cage, and each slot can accept any board type. It is suggested that CPU/Memory boards be installed in the front slots, and I/O and disk boards be installed in the rear slots because of cabling. Should the need arise, however, any of these three board types can be placed in any of the numbered board slots, with the exception of slot 1. Slot 1 should be used by the first I/O board because it is the only slot connected to the onboard SCSI devices.

The first CPU/Memory board is placed in slot 0, followed sequentially by all remaining even numbered slots. If there are boards remaining, they can be installed sequentially in odd numbered slots, if available, in the system rear (with the exception of slot 1 as noted above). See Figure 3-6 and Figure 3-7 for board slot locations.

For CPU/Memory boards being placed in the rear of the system, ensure that the component side is up. If the boards are placed in the front of the system, ensure that the component side is down. See Figure 3-8.

3.4.2.2 Cooling and Power Issues

There should be one power/cooling module (PCM) for every two boards to adhere to cooling and power requirements. The PCMs must be installed adjacent to populated board slots to ensure the fan in the PCM can cool the respective boards.

CPU/Memory Boards and Components 3-11

Note – All empty board slots in Enterprise 4000 or 5000 systems must have a filler panel installed to ensure proper cooling. All empty slots in Enterprise 6000 systems must have load boards installed.

3.4.2.3 PoweredorNonPoweredOn System

1. Carefully insert the board (component side down if in front; component side up if in the rear) in the proper slot in the card cage, ensuring that the board does not slip out of the left and right card guides.

See Figure 3-8.

Board orientation for insertion in the cabinet rear (component side up)

Figure 3-8 Board Replacement

3-12 Ultra Enterprise6000/5000/4000 Systems Manual—November 1996

Board orientation for insertion in the cabinet front (component

2. Ensure that both extraction levers are in the insert position (arrow pointing outward), and that the quarter-turn access slots are unlocked (arrow indicates unlocked position) as you slide the board toward the centerplane receptacles.

See Figure 3-4 and Figure 3-5. The board will not seat fully unless the levers are in this starting position and both quarter-turn access slots are unlocked.

Caution – DO NOT FORCE any board into a slot; it can cause damage to the

board and system. The board should insert and seat smoothly. If it binds, remove the board and inspect the card cage slot for any obvious obstructions. Also inspect both the board and the centerplane for bent pins or other damage.

3. Push the board into the card cage, then simultaneously press both extraction levers to seat the board on the centerplane.

Pushing both levers simultaneously avoids twisting the board and bending the connector pins, and mates the board centerplane connector to the matching receptacle on the centerplane. Do not press on board front panel to seat it—doing so will damage the connector pins.

4. Mechanically lock the board to the system chassis by inserting a Phillips #1 screwdriver into each quarter-turn access slot and then turning to the locked position.

See Figure 3-4.

5. Once the board has been installed, a message similar to the following will be displayed on the monitor (if the system is powered on):

Example depicts screen output when a new CPU/Memory board has been hot-plugged into slot 6 of an operating Enterprise system:

NOTICE: CPU Board Hotplugged into Slot 6 NOTICE: Board 6 is ready to remove

This screen output indicates that the board has been detected by the system and is in the low power mode. Additionally, any subsequent prtdiag(1M) output would include information for board slot 6. Again, note that the system will not use the new board until the system is rebooted.

6. Reboot the system now or schedule a later time to reboot when system disruption will be minimized.

CPU/Memory Boards and Components 3-13

3.4.3 UltraSPARC Modules

Each CPU/Memory board has four connectors for UltraSPARC modules (up to two modules per board, two connectors per module). For each module, there is a connector with 144 pins and a connector with 288 pins. See Figure 3-9.

3.4.4 Handling Precautions

The following precautions should be exercised when handling UltraSPARC modules:

• UltraSPARC modules are static-sensitive and a grounding wrist strap field

kit must be used when handling the modules.

• Always handle the modules by the edges and not by the smaller black heat

sinks that break easily if handled improperly.

• Do not handle the modules by touching the gold pins on the compression

connectors. Natural oils on the hands cause these connectors to oxidize and corrode over a period of time, resulting in the need for module cleaning or replacement.

3.4.4.1 Removing a Module

Each module is locked to the main board with a single standoff and is connected to the main board by two connectors. The pins within the connectors are compressed to the corresponding board mating surfaces by a metal compression bar which, when secured with screws, compresses the module connector pins to the board mating surfaces. See Figure 3-10.

Figure 3-10 Ultra SPARC Module Connector Detail

1. Use the procedures in Section 3.4.1, “Removing a Board,” to remove the applicable CPU/Memory board.

Warning – The heatsinks on the UltraSPARC modules may be hot. Use caution

when removing or installing UltraSPARC modules and avoid contact.

CPU/Memory Boards and Components 3-15

2. Use a 3/32 Hex driver to loosen all screws on each of the compression connectors on the module to be removed (three screws for the 288 pin connector, two screws for the 144 pin connector).

See Figure 3-9.

3. Lift the module straight up, off the board mating surface and the single standoff that locks the module to the board.

Use pressure applied with fingers to assist in removing module from standoff. See Figure 3-11.

Standoff, 1 per module

Figure 3-11 UltraSPARC Module Removal and Replacement

4. Place the module in an antistatic bag.

3-16 Ultra Enterprise6000/5000/4000 Systems Manual—November 1996

3.4.4.2 Installing a Module

To maximize performance when installing UltraSPARC modules on a CPU/Memory board, use all CPU 0 connectors on the lowest numbered slot to the highest numbered slot. After this, if there are modules remaining, use the CPU 1 connectors in the same order.

1. Take the UltraSPARC module out of the protective packaging and inspect for dust on the connectors.

If necessary, clean the connectors with a dry, stiff toothbrush.

2. Remove the applicable CPU/Memory board as indicated in Section 3.4.1, “Removing a Board.”

3. Inspect the board module mating surface. If the surface requires cleaning, use a dry, stiff toothbrush to clean debris from the mating surfaces.

Note – There are miniature silver alignment pins on the compression

connectors which, when the module is properly seated, align with related receptacles on the mating surfaces of the CPU/Memory board. In addition, there is a gold standoff mounted on the CPU/Memory board opposite the module’s smaller board connector. This acts as a standoff for the module as well as an alignment pin.

4. Align the module over the two board receptacles using the single standoff as well as the alignment pins located on the module compression connector as a guide.

See Figure 3-10 and Figure 3-11.

5. Holding the module by the edges, rest it on the board standoff, aligning the compression connectors with the screws.

Firmly but gently press the module straight down until the standoff post snaps into place and the module connectors are fully seated.

6. Tighten the 3/32 hex screws of the module in two stages:

a. Tighten to 3 inch-pounds in the tightening sequence as follows:

CPU/Memory Boards and Components 3-17

Tightening sequence

413 2 5

b. Tighten to 6 inch-pounds in the same tightening sequence.

Caution – Do not over-torque or under-torque the screws. Excessive force can

warp the connector. Insufficient force can cause an incomplete electrical connection.

413 2 5

Figure 3-12 Tightening Compression Connector Screws

7. Use the procedures in Section 3.4.2, “Installing a Board,” to replace the applicable CPU/Memory board.

3-18 Ultra Enterprise6000/5000/4000 Systems Manual—November 1996

3.4.5 Memory Modules (SIMMs)

The CPU/Memory board has 16 SIMM sockets, which are divided into two banks of 8 SIMMs each, Bank 0 and Bank 1. Bank 0 and Bank 1 SIMMs occupy alternate slot locations; Bank 0 SIMMs are in the even numbered slots, and Bank 1 SIMMs are in odd numbered slots. See Figure 3-13.

4. Eject the faulty SIMM by pressing down on the ejection levers on both sides of the SIMM connector.

See Figure 3-14.

Figure 3-14 Ejecting a SIMM

5. Holding the SIMM by its edges, remove it from the slot and place it on an antistatic surface.

3.4.5.2 Installing a Memory Module

Requirements

All banks must have the same size SIMMs, however, SIMMs from different manufactures are interchangeable in a single bank if the SIMMs all have the same capacity and speed. Sort the SIMMs into banks of 8 using the same size SIMMs.

CPU/Memory Boards and Components 3-21

Maximizing Performance

The following guidelines will result in optimal memory interleaving across boards for performance. These guidelines are for optimal performance and are not requirements for a functional system. The guidelines apply to systems with no SIMMS installed and when adding SIMMs to a system; if you are adding SIMMs, you may need to move some SIMMs to meet the guidelines.

1. Install one bank on each board before installing the second bank on any board.

It does not matter whether the first bank is bank 0 or bank 1.

2. Begin with the largest density banks first (128 Mbyte SIMMs), continue with medium sized banks (32 Mbyte SIMMs), and finish with the smallest banks (8 Mbyte SIMMs).

3. If there is remaining memory, start filling the second banks on the boards in the same order as the first banks.

Installation

1. Place the CPU/Memory board on which the SIMM is to be installed on an antistatic mat.

2. Carefully remove the new SIMM from its protective packaging and place it on an antistatic surface.

The bag that the SIMM is packed in makes a good antistatic surface.

3. Press down on the ejector levers at both ends of the SIMM connector slot that will receive the new SIMM.

The connector slot will not accept the SIMM unless the levers are in the insert position. See Figure 3-15.

4. Align the SIMM with the slot.

Hold the SIMM by its edges and orient it so that the two notches at the bottom of the SIMM line up with the two tabs in the SIMM connector. See Figure 3-15.

5. Place your thumbs on the top edge of the SIMM and push the SIMM firmly into its connector.

See Figure 3-16.

3-22 Ultra Enterprise6000/5000/4000 Systems Manual—November 1996

6. Lock the SIMM in place by pushing both ejector levers into the upright position.

See Figure 3-16.

7. Install the CPU/Memory board and detach the wrist strap.

See Section 3.4.2, “Installing a Board.”

8. As you reboot the system, watch for the system banner to verify that the new memory is recognized by the system.

may touch dangerous voltage points or short out components that could result in fire or electric shock.

• Refer servicing of equipment to qualified personnel.

3-1

3.1 Handling Boards and Assemblies

Caution – The chassis AC power cord must remain connected to ensure a

! !

proper ground.

Caution – The I/O boards, their modules, and cards have surface-mount components that can be broken by flexing the boards.

To minimize the amount of board flexing, observe the following precautions:

• Hold the board only by the edges near the middle of the board, where the

board stiffener is located. Do not hold the board only at the ends.

• When removing the board from an antistatic bag, keep the board vertical

until you lay it on the Sun ESD mat.

• Do not place the board on a hard surface. Use a cushioned antistatic mat.

The board connectors and components have very thin pins that bend easily.

• Do not use an oscilloscope probe on the components. The soldered pins are

easily damaged or shorted by the probe point.

• Transport the board in an antistatic bag.

• Be careful of small parts located on the component side of the board.

• Be careful not to drag boards across surfaces as board components are easily

damaged.

Caution – The heatsinks on the board can be damaged by incorrect handling.

! !

3-2 Ultra Enterprise 6000/5000/4000Systems Manual—November 1996

Do not touch the heatsinks while installing or removing the board. Hold the board only by the edges. If a heatsink is loose or broken, obtain a replacement board.

Caution – When inserting the board into slot 4 or slot 10 of a 16-slot card cage, lift the board slightly to avoid damage to the centerplane connectors.

Caution – The heatsinks on the board can be damaged by improper packaging. When storing or shipping the board, ensure that the heatsinks have sufficient protection.

3.2 Filler Panels and Load Boards

All empty board slots in Enterprise systems must have either a filler panel or a load board installed.

• Empty slots in Enterprise 5000 and 4000 systems must have a filler panel

installed.See Figure 3-1.

• Empty slots in Enterprise 6000 systems must have a load board installed.

See Figure 3-2.

3.3 SCSI Termination

The I/O board in slot 1 controls the internal SCSI tray devices. Therefore, the external SCSI connector on the I/O board in slot 1 of a system must be terminated with a SCSI terminator. See Figure 3-3.

Figure 3-3 SCSI Terminator

3-4 Ultra Enterprise 6000/5000/4000Systems Manual—November 1996

3.4 Hot-Plug Feature

Caution – The peripheral power supply provides the precharge voltages required for hot-plug. Do not attempt hot-plug of a system component if the power supply is missing or inoperative. Use prtdiag(1M) to determine the status of the peripheral power supply.

Caution – If the message: NOTICE: Hot Plug not supported in this system is displayed during boot, do NOT attempt hot-plug in this system or

damage to the hardware will occur.

3.5 I/O Boards

Enterprise systems support two types of I/O boards: SBus and Graphics. See Figure 3-4 through Figure 3-7.

The SBus I/O board includes two SYSIO ASICs that provide two SBuses:

• One for two plug-in SBus cards and two fiber interfaces

• One for one plug-in SBus card and the on-board devices (10/100Mbyte TPE

and Single-ended Fast/Wide SCSI)

Note – SBus connector slots 1 and 2 on the SBus I/O board can accommodate a double-wide SBus card.

I/O Boards and Components 3-5

The Graphics I/O board includes one SYSIO ASIC that provides a single SBus for two plug-in SBus cards, two fiber interfaces, and the on-board devices (10/100Mbyte TPE and Single-ended Fast/Wide SCSI).

3.5.1 tpe-link-test? Variable

If the system cannot communicate with a network, the tpe-link-test? settings for the on-board Ethernet ports may be incompatible with the setting at the network hub. The tpe-link-test? variable is set separately for the onboard Ethernet port on each I/O board. The variable is also set for any SBus Ethernet cards in the system. If you have problems verifying connection between Sun equipment and your hub, verify that your hub also has the link test function enabled. See Section 8.5.3.2, “printenv Command,” for information about displaying configuration variables and Section 8.6.1, “Failure of Network Communications,” for additional tpe-link-test? information. Also, refer to the manual provided with your hub.

1. Ensure that the SBus card is on an antistatic mat.

2. For DSBE/S and FSBE/S cards: remove the two outer retaining screws (see Figure 3-18), but do NOT remove the middle screw or the springfinger.

Use a #0 Phillips screwdriver and a 3/16 nut driver or socket wrench.

3. For DSBE/S and FSBE/S cards, configure jumper J0302 for Link Integrity Test functionality. See Figure 3-18 (DSBE/S) or Figure 3-19 (FSBE/S).

a. Put the shunt over both pins to disable the Link Integrity Test. See

Figure 3-20 “Disabled.”

b. Put the shunt in one pin to enable the Link Integrity Test. See

Figure 3-20 “Enabled.”

Caution – If you choose to disable the test, it must be disabled both at the hub
