    DIMMs must be added four at a time within the same bank Note – In the Sun Enterprise 420R server, each memory bank comprises two slots on the main logic board, and two slots on the memory riser card. As you add memory, fully populate each bank by inserting DIMMs into the two slots comprising each bank on both the main logic board and on the memory riser card.

  • Page 93: Sun Enterprise 420R System Memory Interleaving

    Always wear a grounding strap when you handle the modules. Sun Enterprise 420R System Memory Interleaving Whenever memory banks 0 and 1 are populated with identical capacity DIMMs, memory reads and writes are automatically interleaved between the two banks. This is called two-way interleaving.

  • Page 94: About Cpu Modules

    CPUs operate at 450 MHz, the UPA data bus could operate at one fourth the clock speed at 112.5 MHz. A qualified service provider must remove and replace CPU modules in your system. For information about installing and removing CPU modules, see the Sun Enterprise 420R Server Service Manual. Configuration Rules The following rules apply for your system: You can install up to four UltraSPARC II CPU modules into the server.

  • Page 95: About Peripheral Component Interconnect (Pci) Buses

    About Peripheral Component Interconnect (PCI) Buses All system communication with storage peripherals and network interface devices is mediated by a Ultra Port Architecture-to-Peripheral Component Inter-connect (UPA-to-PCI) bridge chip, located on the system’s main logic board. This bridge chip manages communication between the UPA bus and the system’s two PCI buses. These PCI buses support slots for up to four PCI interface cards.

  • Page 96: Configuration Rules

    Examples of high-throughput interfaces are dual-channel UltraSCSI host adapters and ATM-622 interfaces. You can also improve overall system availability by installing redundant storage or network interfaces on separate PCI buses. Sun Enterprise 420R Server Owner’s Guide • October 1999...

  • Page 97: About Disk Array Configurations And Concepts

    For instance, you can combine the two disks c1t2d0s2 and c1t3d0s2 into the metadevice /dev/md/rdsk/d0. The Sun Enterprise 420R server’s internal disks support RAID 1, RAID 0, and RAID 1 + RAID 0. More complicated configurations, including RAID 5, are supported using external disk arrays and one or more PCI host adapter cards.

  • Page 98: Disk Concatenation

    The scheme is sometimes called RAID 1, where RAID stands for redundant arrays of inexpensive disks. RAID 1 offers the highest level of data protection, but storage costs are high, since all data is stored twice. Sun Enterprise 420R Server Owner’s Guide • October 1999...

  • Page 99: Disk Striping: Raid 0

    Disk Striping: RAID 0 Disk striping (sometimes called RAID 0) is a technique for increasing system throughput by using several disk drives in parallel. Whereas in non-striped disks the operating system writes a single block to a single disk, in a striped arrangement each block is divided and portions of the data are written to different disks.

  • Page 101: About Internal Disk Drives

    About Internal Disk Drives The Sun Enterprise 420R server supports up to two internal, hot-pluggable UltraSCSI disk drives. Drives are 3.5-inches wide and 1-inch high (8.89-cm x 2.54-cm). The drives are supported by the 40-Mbyte per second UltraSCSI interface on the system’s main logic board.

  • Page 102: Configuration Rules

    The exact hot-plug procedure depends on which version of the Solaris operating environment you are using. For the complete procedure, refer to Platform Notes: Sun Enterprise 420R Server, available on the Solaris on Sun Hardware AnswerBook. This AnswerBook documentation is provided on the Solaris Supplement CD for the Solaris release you are running.

  • Page 103: About Power Supplies

    About Power Supplies A power distribution board delivers DC power for all internal system components. The system’s power supplies plug in to connectors on this board, and when both supplies are installed, they share equally in satisfying the power demands of the system.
  • Page 104 Three LED indicators on the front of the power supply display AC and DC status, and fault conditions. For additional details, see “Power Supply LEDs” on page 139. Note – Sun Enterprise 420R power supplies will shut down automatically in response to certain over-temperature and power fault conditions. To recover from an automatic shutdown, you must disconnect the AC power cord, wait roughly 10 seconds, and then reconnect the power cord.

    Signal levels are controlled by jumpers located on the system’s main logic board. The default setting is EIA-423. For more information about configuring the serial port jumpers, see the Sun Enterprise 420R Server Service Manual. See “Reference for the Serial Port A and B Connectors” on page 155 for the connector diagram, back panel icon, and pin assignments.

  • Page 107: About The Parallel Port

    About the Parallel Port The system provides one IEEE 1284-compatible, bidirectional parallel port for connecting the system to a local printer or other compatible parallel device. Connectivity is provided by a standard 25-pin DB-25 connector on the back panel of the system. The parallel port operates at a 2-Mbytes per second data transfer rate and supports the enhanced parallel port (EPP) protocol modes as well as standard Centronics, Nibble, and Byte modes.
