• UEFI-compliant server firmware
Lenovo ThinkSystem firmware is Unified Extensible Firmware Interface (UEFI) 2.5 compliant. UEFI
replaces BIOS and defines a standard interface between the operating system, platform firmware, and
external devices.
Lenovo ThinkSystem servers are capable of booting UEFI-compliant operating systems, BIOS-based
operating systems, and BIOS-based adapters as well as UEFI-compliant adapters.
Note: The server does not support DOS (Disk Operating System).
• Large system-memory capacity
The server supports registered DIMMs (RDIMMs), load-reduced DIMMs (LRDIMMs), three-dimensional
stack registered DIMMs (3DS RDIMMs) and DC Persistent Memory Modules (DCPMMs). For more
information about the specific types and maximum amount of memory, see "Specifications" on page 5.
• Flexible network support
The server has a connector for the LOM adapter, which provides two or four network connectors for
network support.
• Integrated Trusted Platform Module (TPM)
This integrated security chip performs cryptographic functions and stores private and public secure keys.
It provides the hardware support for the Trusted Computing Group (TCG) specification. You can
download the software to support the TCG specification.
Trusted Platform Module (TPM) has two versions - TPM 1.2 and TPM 2.0. You can change the TPM
version from 1.2 to 2.0 and back again.
For more information on TPM configurations, see "Enable TPM/TCM" in the Maintenance Manual.
Note: For customers in the Chinese Mainland, a Lenovo-qualified TPM 2.0 adapter or a Trusted
Cryptographic Module (TCM) adapter (sometimes called a daughter card) may be pre-installed.
• Large data-storage capacity and hot-swap capability
The server models support a maximum of fourteen 3.5-inch hot-swap SAS/SATA storage drives or a
maximum of twenty-four 2.5-inch hot-swap SAS/SATA/NVMe storage drives.
With the hot-swap feature, you can add, remove, or replace drives without turning off the server.
• Light path diagnostics
Light path diagnostics provides LEDs to help you diagnose problems. For more information about the light
path diagnostics, see:
– "Front I/O assembly" on page 24
– "Rear view LEDs" on page 29
– "System board LEDs" on page 33
• Mobile access to Lenovo Service Information website
The server provides a QR code on the system service label, which is on the cover of the server, that you
can scan using a QR code reader and scanner with a mobile device to get quick access to the Lenovo
Service Information website. The Lenovo Service Information website provides additional information for
parts installation and replacement videos, and error codes for server support.
