Lenovo System x3650 M5 Installation And Service Manual page 27

The hot-swap server models support a maximum of twenty-six 2.5-inch or 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 sixteen 2.5-inch or 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.
• Large system-memory capacity
The server can support up to 1.5 TB of system memory. The server provides 24 dual inline memory
module (DIMM) connectors. The server memory controller supports error correcting code (ECC) for PC4-
17000 (DDR4-2400), DDR4 (fourth-generation double-data-rate), synchronous dynamic random access
memory (SDRAM) DIMMs.
• Mobile access to 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 Service
Information website. The Service Information website provides additional information for parts installation
and replacement videos, and error codes for server support. For the QR code, see QR code information
on page Chapter 1 "The System x3650 M5 server" on page 1.
• Multi-core processing
The server supports up to two Intel Xeon E5-2600 v4 series multi-core microprocessors. The server
comes with a minimum of one microprocessor.
• PCI adapter capabilities
The server has two PCI interface risers. See "Replacing an adapter" on page 207 for detailed information.
• SD adapter
A raid controller for Secure Digital (SD) media. It has two upstream connections, a USB connection to the
server chipset, and an MMC connection to the IMM2.1.
• Redundant connection
The addition of the optional Ethernet adapter provides failover capability to a redundant Ethernet
connection with the applicable application installed. If a problem occurs with the primary Ethernet
connection and the optional Ethernet adapter is installed on the server, all Ethernet traffic that is
associated with the primary connection is automatically switched to the optional redundant Ethernet
adapter 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, 750-watt, 900-watt, 1300-watt or 1500-watt hot-swap
power supplies and six hot-swap fans, which provide redundancy and hot-swap capability 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 the minimum of one 550-watt, 750-watt, 900-watt, 1300-watt or 1500-
watt hot-swap power supply and four fans. If two or more fans fail, your server will automatically turn off
after six minutes due to thermal limitation.
You must install the fifth and sixth fans when you install the second microprocessor in the server. You can
order the second optional power supply for power redundancy.
Note: You cannot mix different wattages and different 80 plus efficiency level of power supplies in the
server.
