The server supports synchronous dynamic random-access memory (SDRAM) registered dual inline
memory modules (DIMMs) with error correcting code (ECC). For more information about the specific types
and maximum amount of memory, see
• 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 when the software is available.
Note: For customers in Chinese Mainland, integrated TPM is not supported. However, customers in
Chinese Mainland can install a Trusted Cryptographic Module (TCM) adapter or a Lenovo-qualified TPM
adapter (sometimes called a daughter card).
• Large data-storage capacity and hot-swap capability
The hot-swap server models support a maximum of fourteen 3.5-inch hot-swap Serial Attached SCSI
(SAS) hard disk drives or hot-swap Serial ATA (SATA) hard disk drives. The simple-swap server models
support a maximum of eight 3.5-inch simple-swap SATA hard disk drives.
With the hot-swap feature, you can add, remove, or replace hard disk 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 Light path diagnostics panel and Light path diagnostics LEDs.
• 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, replacement videos, and error codes for server support.
• Active Energy Manager
Lenovo XClarity Energy Manager is a power and temperature management solution for data centers. You
can monitor and manage the power consumption and temperature of Converged, NeXtScale, System x,
and ThinkServer servers, and improve energy efficiency using Lenovo XClarity Energy Manager.
• Redundant networking connection
The Lenovo XClarity Controller provides failover capability to a redundant Ethernet connection with the
applicable application installed. If a problem occurs with the primary Ethernet connection, all Ethernet
traffic that is associated with the primary connection is automatically switched to the optional redundant
Ethernet connection. If the applicable device drivers are installed, this switching occurs without data loss
and without user intervention.
• Redundant cooling and optional power capabilities
The server supports a maximum of two 550-watt or 750-watt hot-swap power supplies and three dual-
motor non hot-swap fans, which provide redundancy for a typical configuration. The redundant cooling by
the fans in the server enables continued operation if one of the fans fails. The server comes with one 550-
watt or 750-watt hot-swap power supply and three non hot-swap fans.
Note: You cannot mix 550-watt and 750-watt power supplies in the server.
• ThinkSystem RAID support
The ThinkSystem RAID adapter provides hardware redundant array of independent disks (RAID) support
to create configurations. The standard RAID adapter provides RAID levels 0 and 1. An optional RAID
adapter is available for purchase.
