Page 33 1.1.2 Power Supply The power supply, shown in Figure 1-4, provides 650 watts of power and includes a system maintenance panel with three status LEDs. The power supply plugs directly into the backplane through two 240-pin connectors. Connection to the fan tray is provided through a single connector located on the right rear side of the power supply.
Page 34 1.1.3 Fan Tray The SPARCserver 1000 fan tray, shown in Figure 1-5, provides cooling for the power supply, system boards, and the SCSI tray assemblies. In addition, this module routes AC power from the chassis rear to the power supply. Each fan has a fail sensor to enable orderly system shutdown if a fan fails.
Page 35 1.1.4 SCSI Tray Assembly The SCSI tray assembly, shown in Figure 1-6, consists of: • Backup device tray on the left side • SCSI disk drive tray on the right side • Control board on top of the SCSI-2 disk drives The SCSI tray assembly mounts above the power supply in the chassis front.

This kit contains the Sun approved Sun ESD mat which has cushioning to protect underside components, prevent board flexing, and provide ESD protection.
Page 80 1. A disposable EDS kit can lose effectiveness after a single use. 5.2 Tools Required Have the following tools available before you begin: • Sun ESD mat and grounding wrist strap • #0 and #1 Phillips screwdriver • Flat-blade screwdriver SPARCserver 1000 System Service Manual—June 1996...
Page 81 Powering Off and On Use the information in this chapter to power off and on the system. 6.1 Powering Off the System Once the diagnostics are completed, you can remove the TTY terminal. However, do not disconnect the terminal while the system is running. Before turning off the system power, halt the operating system.
Page 82 5. Turn the key switch on the front panel to the Standby position (fully counterclockwise). See Figure 6-1. Standby Diagnostics Locked Figure 6-1 Key Switch in the Standby Position 6.

Page 85 5. Watch the terminal screen for possible error messages from the POST diagnostic program. POST tests subassemblies in the server and some interface paths between subassemblies. At the conclusion of testing, POST automatically attempts to reconfigure the system, omitting any parts of the system that have failed diagnostics. If there are no faults, or if POST completes a successful reconfiguration of the detected faults, the system boots.

Page 129 Note – A system board can be moved to any slot, especially during troubleshooting. However, by convention, the system master is in slot 0. The factory ships systems in this configuration. It is possible POST may assign a new system master in a different slot if the original system master fails. If this occurs, correct it and install a fully functional system board in slot 0.

The 8 Mbyte (low-density) SIMMs use 1Mbit by 4bit DRAMs. Two vendors are used, so a slight variation exists in physical appearance between the two products.

E.5.2 Ethernet Cables The main network cable must be connected to the on-board Ethernet connector on system board 0.

E.5.3 Video Cables Only one CGSIX interface is allowed per system.
Page 203 Glossary Air Restrictor Board A blank board with a special air deflector fin to simulate the airflow pattern of an actual board. If air restrictor boards are not installed in blank slots, a condition called a “thermal short” is created. Thermal shorts severely reduce the cooling capability of the system, which can lead to equipment damage.
Page 204 The term board refers to printed circuit boards larger than a certain size (for example, larger than 3x5-inch SBus cards and SPARC modules). There are two types of boards in the SPARCserver 1000 system: system boards (maximum of four) and control board (one only). See also Card and Module.
Page 205 When there are at least two SuperSPARC modules in the system, a system of bus arbitration is required to govern which processor has control of the system resources at any moment. The SPARCserver 1000 arbitration system consists of one Central Arbiter (CARB) on the control board and one Board Arbiter (BARB) on every system board.
Page 206 By convention, boards are installed in a card cage (not a board cage). The SPARCserver 1000 system card cage is accessed from the rear of the enclosure that contains up to four system or other boards. The card cage provides card guides to guide the board into the backplane.
