• Built-in monitoring for fan, power, temperature, voltage, and power-supply redundancy
• Cable-presence detection on most connectors
• Chipkill memory protection
• Single-device data correction (SDDC) for x4 DRAM technology DIMMs. Ensures that data is available
on a single x4 DRAM DIMM after a hard failure of up to two DRAM DIMMs. One x4 DRAM DIMM in
each rank is reserved as a space device.
• Diagnostic support for ServeRAID and Ethernet adapters
• Error codes and messages
• Error correcting code (ECC) L3 cache and system memory
• Full Array Memory Mirroring (FAMM) redundancy
• Hot-swap cooling fans with speed-sensing capability
• Hot-swap hard disk drives
• Hot-swap power supplies
• Information and light path diagnostics LED panels
• Integrated management module II
• Light path diagnostics LEDs for DIMMs, microprocessors, hard disk drives, solid state drives, power
supplies, and fans
• Memory mirroring and memory sparing support
• 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 the power-on self-test. The power-on self-test logically
maps out the memory with the uncorrectable error, and the server restarts with the remaining installed
memory.
• 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
• NMI button
• Parity checking on the PCIe buses
• Power management: compliance with Advanced Configuration and Power Interface (ACPI)
• Power-on self-test
• Predictive Failure Analysis (PFA) alerts on memory, SAS/SATA hard disk drives or solid state drives
• Redundant hot-swap power supplies and redundant hot-swap fans
• Remind button to temporarily turn off the system-error LED
• Remote system problem-determination support
• ROM-based diagnostics
• ROM checksums
• Serial Presence Detection (SPD) on memory, vital product data (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 UEFI
• 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 (POST and IMM)
• Systems-management monitoring through the Inter-Integrated Circuit (I2C) protocol bus
• Uncorrectable error (UE) detection
• Upgradeable UEFI, DSA, and IMM firmware, locally or over the LAN
• Wake on LAN capability
