• Memory error correcting code and parity test
• Memory downsizing (non-mirrored memory). After a restart of the server after the memory controller
detects a non-mirrored uncorrectable error and the memory controller cannot recover operationally, the
IMM logs the uncorrectable error and informs POST. POST logically maps out the memory with the
uncorrectable error, and the server restarts with the remaining installed memory.
• Memory mirroring and memory rank sparing support
• Memory thermal throttling
• Menu-driven setup, system configuration, and redundant array of independent disks (RAID) configuration
programs
• Microprocessor built-in self-test (BIST), internal error signal monitoring, internal thermal trip signal
monitoring, configuration checking, and microprocessor and voltage regulator module failure identification
through light path diagnostics
• Nonmaskable interrupt (NMI) button
• Operating system memory on-lining (capacity change)
• Parity checking on the PCIe buses
• PCIe hot-add and remove support
• PCIe hot-plug (microprocessor 2 and 3 only)
• Power management: compliance with Advanced Configuration and Power Interface (ACPI)
• Power-on self-test (POST)
• Predictive Failure Analysis (PFA) alerts on memory, SAS/SATA hard disk drives or solid state drives, and
fans.
• Redundant Ethernet capabilities with failover support
• Redundant hot-swap power supplies and redundant hot-swap fans
• Redundant network interface card (NIC) support
• Remind button to temporarily turn off the system-error LED
• Remote system problem-determination support
• ROM-based diagnostics and upgrade of flash ROM-based code and diagnostics
• ROM checksums
• Serial Presence Detection (SPD) on memory, VPD on system board, power supply, and hard disk drive or
solid state drive backplanes, microprocessor and memory expansion tray, and Ethernet adapters
• Single-DIMM isolation of excessive correctable error or multi-bit error by the Unified Extensible Firmware
Interface (UEFI)
• SMI clock failover
• SMI lane failover
• SMI packet retry
• Solid-state drives
• Standby voltage for systems-management features and monitoring
• Startup (boot) from LAN through remote initial program load (RIPL) or dynamic host configuration
protocol/boot protocol (DHCP/BOOTP)
• System auto-configuring from the configuration menu
• System-error logging (UEFI/POST and IMM)
• Systems-management monitoring through the Inter-Integrated Circuit (I2C) protocol bus
• Temperature and fan monitoring
• Uncorrectable error (UE) detection
• Upgradeable POST, Unified Extensible Firmware Interface (UEFI), diagnostics, IMM firmware, and read-
only memory (ROM) resident code, locally or over the LAN
• Vital product data (VPD) on the microprocessor and memory expansion modules, PCIe expansion
modules, base I/O module, storage and I/O module, power supplies, and SAS/SATA (hot-swap hard disk
drive or solid state drive) backplanes
• Wake on LAN capability
