3.4 Maximum and Minimum Levels of POST Two levels of POST are available: maximum (max) level and minimum (min) level. The system initiates the selected level of POST based upon the setting of diag-level, a nonvolatile random access memory (NVRAM) variable. The default setting for diag-level is max. An example of a max level POST output on serial port A is provided in Section 3.4.1 “Diag-Level NVRAM Variable Set to max” on page 3-6.

the system unit powers on, no further action is required. If the system unit does not power on, the keyboard may be defective. Connect a spare Sun Type-5 keyboard to the system unit and press the Power-on key. If the wall receptacle AC power has been verified, the CPU module is properly seated, and a spare Sun Type-5 keyboard has been connected to the system unit and the Power-on key has been pressed but the system unit does not power up, the system unit power supply may be defective. See Section 4.

4.3 Hard Drive or CD-ROM Drive Failure This section provides hard drive and CD-ROM drive failure symptoms and suggested actions. Symptom A hard drive read, write, or parity error is reported by the operating system or customer application. A CD-ROM drive read error or parity error is reported by the operating system or customer application. Action Replace the drive indicated by the failure message. The operating system identifies the internal drives as listed in the following table.
PAGE 54
● At the system prompt, type: ok reset-all ok probe-scsi If the drives respond and a message is displayed, the system SCSI controller has successfully probed the devices. This is an indication that the motherboard is operating correctly. If one drive does not respond to the SCSI controller probe but the others do, replace the unresponsive drive. If one internal disk drive is configured with the system and the probe-scsi test fails to show the device in the message, replace the drive.

C.1.1 UPA The UPA is a cache-coherent processor-to-memory interconnect. A key advantage of the UPA processor-to-memory interconnect is a scalable bandwidth through the support of multiple bussed interconnects for both data and address. Other advantages include more bandwidth, high-performance graphics support with two-cycle, single-word writes on the 64-bit UPA data bus, and centralized coherence and memory controller functions (see FIGURE C-1).
PAGE 156
Note – The PrestoServe™ 2.4.2 release is incompatible with the Solaris 2.5.1 software environment when running on a Sun Ultra 2 Series system. For information about working around that problem, refer to SMCC Open Issues Supplement Solaris 2.5.1, part number 802-5340. C.1.3 UltraSPARC I Processor The UltraSPARC I processor is mounted on a module that is plugged into the system unit or server motherboard. Up to two modules are supported, one CPU for each module.

even in the presence of conditional branches and cache misses. This sustained performance is supported by a decoupled prefetch and dispatch unit with instruction buffer. The UltraSPARC II processor supports both 2-D and 3-D graphics, as well as image processing, video compression and decompression, and video effects through the sophisticated VIS.
PAGE 158
Characteristic memory performance includes a peak memory read bandwidth of 667 Mbytes per second and a peak memory write bandwidth of 485 Mbytes per second with random accesses to the DRAM using eight or more DSIMMs. The following figure shows the DSIMM group and bank layout. Note – Two pairs of DIMMs form a group of four DIMMs. All four DIMMs within a group must be the same size. The minimum memory requirement is four DIMMs in Group 0. DIMMs can be installed in Group 1, Group 2, or Group 3 in any order.
PAGE 159
C.1.6 Graphics and Imaging (Workstation Only) The system unit takes advantage of UPA features to provide high performance UPA graphics. An FBC ASIC provides acceleration for 2-D and 3-D imaging primitives (see FIGURE C-1). The UPA graphics consist of the FBC ASIC, the FBRAM, RAMDAC, and associated circuitry. The UPA graphics connect to the system unit through the UPA64S expansion connector. FBRAM is a standard DRAM that includes a multilevel cache. The FBC ASIC permits a write-mostly interface.

The link test function at the host or hub is either enabled (link test enabled or 1) or disabled (link test disabled or 0). The IEEE 802.3 10BASE-T specification requires that the link test be enabled at both the host and the hub. Although link test disabled does not conform to the specification, it is often encountered in real-world 10BASE-T network installations. Some hubs from various vendors can exhibit any of the following: C.1.11.3 ■ Link test is “hardwired” enabled — link test is always enabled.

Note – Power values listed in the following table translate to worse-case current requirements. Peak current requirements are greater. Note that the amount of power dissipated as heat is not listed. Also, the maximum delivered power is not the same as the sum of the output powers because of configuration restrictions and peripheral power-dissipation limits that are smaller than peak current requirements. All component power supply budget values are measured as a function of wattage.
PAGE 180
C.3 Power Management To meet EPA Energy Star requirements, the system unit power consumption is lower than 30 watts. In system unit software monitors system unit activity and based on the system unit control settings, system unit software saves the machine state (including the memory) onto the hard drive and halts the operation system. The system unit software then turns off the power supply.

the number of events, or signal changes, that occur in 1 second. Because one event can actually encode more than one bit in high-speed digital communications, baud rate and bits per second are not always synonymous, and the latter is the more accurate term to apply to modems. For example, a socalled 9600-baud modem that encodes four bits per event actually operates at 2400 baud but transmits 9600 bits per second (2400 events times 4 bits per event) and thus should be called a 9600-bps modem.

Modem Modulator/demodulator. A device that enables a machine or terminal to establish a connection and transfer data through telephone lines. Because a computer is digital and a telephone line is analog, modems are needed to convert digital into analog and vice versa.
