manual abstract
If this LED is on, the power is on. If this LED is blinking, the power-off sequence is in progress. o STANDBY Green Indicates the standby state of the main unit. If this LED is on, the power can be turned on. A CHECK Amber Indicates the main unit operating status. (This is used to indicate a maintenance target, or it indicates that the unit cannot be started.) If this LED is on, a system error has been detected. 1-18 SPARC Enterprise M8000/M9000 Servers Overview Guide • August 2009 Operator Panel Switches The switches on the operator panel include the mode switch for setting the operation mode and the POWER switch for turning on and off the SPARC Enterprise server. To switch between system operation mode and maintenance mode, insert the dedicated key of the high-end server and change the mode switch setting. TABLE 1-5 lists functions of the switches on the operator panel. TABLE 1-5 Operator Panel Switches Switch Name Function 0 POWER switch Controls the main unit power. 1 MODE switch Selects between maintenance and normal operation. Use the dedicated key managed by the customer to switch between normal and maintenance modes. Q Locked This mode is set for normal operation. e ic £ e o- This mode is set for maintenance. Chapter 1 System Overview 1-19 1.3 Server Components This section describes the components of both high-end servers. For details on each, see the SPARC Enterprise M8000/M9000 Servers Service Manual. ■ CPU Module ■ CPU/Memory Board Unit ■ I/O Unit ■ FAN Unit ■ Power Supply Unit ■ Crossbar Unit ■ Clock Control Unit ■ Operator Panel ■ XSCF Unit ■ Internal Drive Units ■ Hard Disk Drive ■ CD-RW/DVD-RW Drive Unit/Tape Drive Unit 1.3.1 CPU Module The CPU Module (CPUM) contains a SPARC64 VI/SPARC64 VII CPU and a DC-DC converter (DDC). Up to four CPUMs can be mounted on a CPU/Memory Board Unit. The CPUM has the following features: ■ The CPUM contains a SPARC64 VI/SPARC64 VII, a high-performance multicore CPU that uses the latest LSI process. ■ If an unforeseen fault is detected, the SPARC64 VI/SPARC64 VII CPU enables operation to continue without interruption by using an automatic recovery function, automatic retry function, or automatic degradation function, depending on how the system is configured. ■ A redundant DDC configuration enables continuous operation even if a DDC fails. 1-20 SPARC Enterprise M8000/M9000 Servers Overview Guide • August 2009 1.3.2 CPU/Memory Board Unit The CPU/Memory Board Unit (CMU) contains CPUMs, memory modules, and a DDC. The CMU with an I/O Unit can be combined to construct one or more domains. The CMU has the following features: ■ Contains an interconnect LSI module that uses the latest LSI process. ■ Uses Double Data Rate (DDR)II DIMM memory. ■ Supports the DR function that enables hot maintenance and replacement of CMUs during system operation, and enables addition and deletion of active CMUs during system operation. ■ A redundant DDC configuration enables continuous operation even if a DDC fails. 1.3.3 I/O Unit The I/O Unit (IOU) consists of a PCIe bridge control LSI module, a printed circuit board containing a DDC, a hard disk drive (HDD), PCIe slots, and PCI cassettes for the IOU. The IOU and the CMU can be combined to configure a server. The IOU has the following features: ■ It contains eight PCIe slots. ■ The IOU Onboard Device Card_A (IOUA) can be used to connect the in-cabinet Drive Unit (2.5-inch SAS interface), the in-cabinet CD-RW/DVD-RW Drive Unit, and the Tape Drive Unit. The LAN port (1000BASE-T/100Base-TX/10Base-T) mounted on the card can be used. ■ It supports PCI hot-plug for External I/O Expansion Units and PCIe slots. ■ Link Card can be used to connect IOU to External I/O Expansion Unit. ■ It supports the DR function that enables active maintenance and replacement of IOUs during system operation and enables addition and deletion of active IOUs during system operation. ■ Insert the PCI Card into one of the supplied cassettes before inserting it into a built-in PCIe slot in the IOU. A PCI card whose length is up to 177.8 mm (short size) can be mounted in a slot. ■ A redundant DDC configuration enables continuous operation even if a DDC fails. Chapter 1 System Overview 1-21 1.3.4 FAN Unit The FAN Unit is used to cool the server. There are two types of FAN Units, with the following features: ■ A redundant fan configuration enables continuous system operation even if a fan fails during system operation. ■ Active (hot) system maintenance or replacement of a faulty FAN Unit can be performed during system operation. 1.3.5 Power Supply Unit The Power Supply Unit (PSU) feeds power to each unit, and has the following features: ■ A redundant configuration enables the system operation to continue without interruption even if a Power Supply Unit fails during system operation. ■ Active (hot) system maintenance or replacement of a faulty Power Supply Unit can be performed during system operation....
