Server Features: Discusses the UltraSPARC T2 processor (4, 6, or 8 cores) based on CMT technology , memory (up to 64 GB FB-DIMMs) , and System Reliability, Availability, and Serviceability (RAS) features like hot-swappable component replacement (power supplies, fan units, hard drives).
Remote Manageability with ILOM: Explains the Sun ILOM firmware server fault diagnosis system, which monitors components and uses the ALOM CMT compatibility shell for running diagnostics.
Chassis Overview: Details infrastructure boards (Motherboard, PDB, Hard Drive Backplane) and system cables.
CHAPTER 2. Server Diagnostics
Overview: Covers the use of LEDs, ILOM firmware, POST, and Solaris Predictive Self-Healing (PSH) for fault isolation.
Service Processor Firmware Diagnosis (ALOM CMT Shell): Details commands for fault handling, including:
showfaults: Displays Environmental, POST, and PSH detected faults.clearfault: Manually clears PSH diagnosed faults.showenvironment: Displays a snapshot of environmental status (temperatures, voltage, fan status).showfru: Displays Field-Replacable Unit information.
Running POST and clearfault command on Sun SPARC: Describes configuring POST mode (
diag_mode,diag_level) and the procedure for running POST in maximum mode for hardware verification and clearing POST detected faults.Automatic System Recovery (ASR) Command Management: Explains the ASR blacklist (
asr-db) and commands:showcomponent,disablecomponent, andenablecomponent.
CHAPTER 3. Preparing to Service the System: Safety information (ESD) , required tools, powering off, and extending the server to the maintenance position.
CHAPTER 4. Replacing Hot-Pluggable and Hot-Swappable Components: Step-by-step procedures for hot-swappable component replacement of hard drives, fan modules, and power supplies.
CHAPTER 5. Servicing Motherboard Components: Covers:
Servicing FB-DIMMs: Includes locating a faulty FB-DIMM and crucial guidelines for T5220 FB-DIMM memory configuration and replacement.
Removing/Installing the Air Baffle, PCIe/XAUI Risers, PCIe/XAUI Cards, Battery, SCC Module, and Motherboard Assembly.
CHAPTER 6. Servicing Infrastructure Boards and Components: Covers cold-swappable FRUs like the DVD/USB Module, Fan Power Boards, Hard Drive Cage, Hard Drive Backplane, Power Distribution Board, Power Supply Backplane (T5220 only), and Paddle Card.
CHAPTER 7. Returning the Server to Operation: Steps to install the top cover, reinstall the server in the rack, and power on the system.
APPENDIX A. Field-Replacable Units (FRUs): Provides detailed exploded diagrams and tables for FRU identification.
APPENDIX B. Connector Pinouts: Lists pin assignments for external connectors (Serial MGT, NET MGT, DB-9, USB, Gigabit Ethernet).
