Integrated functions and I/O connectors
• Lenovo XClarity Controller (XCC), which provides service processor control and monitoring functions, video
controller, and remote keyboard, video, mouse, and remote drive capabilities.
– The server supports Lenovo XClarity Controller 2 (XCC2). For additional information about Lenovo XClarity
Controller 2 (XCC2), refer to
• Front connectors:
– One VGA connector (optional)
– One USB 3.2 Gen1 (5 Gbps) connector
– One USB 2.0 connector with XCC system management function
– One external diagnostics connector
– One integrated diagnostics panel (optional)
• Rear connectors:
– One VGA connector
– Three USB 3.2 Gen1 (5 Gbps) connectors
– One XCC system management port
– Two or four Ethernet connectors on the OCP module (optional)
– One serial port (optional)
Network
• OCP module, which provides two or four Ethernet connectors for network support
Note: If the ThinkSystem V3 Management NIC Adapter Kit (management NIC adapter) is installed on the server, it
will not be displayed on the PCIe card list of system management software, such as XCC, LXPM, and so on.
System fan
• Supported fan types:
– Standard fan (60 x 60 x 36 mm, single-rotor, 17000 RPM)
– Performance fan (60 x 60 x 56 mm, dual-rotor, 21000 RPM)
• Fan redundancy: N+1 redundancy, one redundant fan rotor
– One processor: five hot-swap system fans (one redundant fan rotor)
– One processor with middle/rear bay or Riser 3, or two processors: six hot-swap system fans (one redundant fan
rotor)
Notes:
• Single-rotor hot-swap fans cannot be mixed with dual-rotor hot-swap fans.
• The redundant cooling by the fans in the server enables continued operation if one rotor of a fan fails.
• When the system is powered off but still plugged in to AC power, fans 1 and 2 may continue to spin at a much lower
speed. This is the system design to provide proper cooling.
Power supplies
The server supports up to two hot-swap power supplies for redundancy.
