The maximum video resolution is 1920 x 1200 at 60 Hz.
Available when the serial port cable is installed in the server.

Network
OCP module Note The server features three OCP slots: OCP 1 and OCP 2 are located on the rear side, and OCP 3 is positioned at the front when the customer configures the front adapter assembly. OCP module 1 and front OCP module 3 are alternatives. When front OCP module 3 is configured, OCP module 1 will be disabled. OCP module 1 and front OCP module 3 take priority over OCP module 2.

RAID support
Onboard NVMe ports with software RAID support (Intel VROC NVMe RAID) and JBOD Intel^® VROC standard: requires an activation key and supports RAID levels 0, 1, and 10 Intel^® VROC Premium: requires an activation key and supports RAID levels 0, 1, 5, and 10 Intel^® VROC Boot: requires an activation key and supports RAID level 1 only

Intel^® VROC Premium: requires an activation key and supports RAID levels 0, 1, 5, and 10
Intel^® VROC Boot: requires an activation key and supports RAID level 1 only

System fan
Supported fan-pack types: Standard fan-pack 4056 (28000 RPM, single rotor) Performance fan-pack 4056 (28000 RPM, dual rotors) Fan redundancy: N+1 redundancy, one redundant fan rotor One processor: three hot-swap dual-rotor system fan-packs (one redundant fan rotor) Two processors: four hot-swap dual-rotor system fan-packs (one redundant fan rotor) Note The redundant cooling by the fans in the server enables continued operation if one rotor fails. When the system is powered off but still plugged in to AC power, and XCC has detected that OCP modules are installed, fan-pack 2 and 3 may continue to spin at a much lower speed. This is the system design to provide proper cooling.

Electrical input and power policy

Common Redundant Power Supply (CRPS) and CRPS Premium are supported as listed below:

Table 1. Electrical input for power supply units
Power supply	100–127 V ac	200–240 V ac	240 V dc	-48 V dc	CRPS	CRPS Premium

1300-watt 80 PLUS Titanium	√	√	√			√
2000-watt 80 PLUS Titanium		√	√			√

One or two hot-swap power supply units for redundancy or over-subscription (OVS) support:

Note

CRPS PSUs do not support OVS, zero-output mode or vendor mixing. Zero Output Mode and Non-redundant will not be displayed on Lenovo XClarity Controller web interface when installed with CRPS PSUs.
1+0 indicates that the server has only one power supply unit installed and the system does not support power redundancy, while 1+1 indicates that two power supply units are installed and redundancy is supported.

CAUTION

240 V dc input is supported in Chinese Mainland ONLY.
Power supply with 240 V dc input cannot support hot plugging power cord function. Before removing the power supply with dc input, please turn off server or disconnect dc power sources at the breaker panel or by turning off the power source. Then, remove the power cord.

Minimal configuration for debugging
One processor in processor socket 1 One memory module in slot 7 One power supply unit One HDD/SSD drive, one M.2 drive (if OS is needed for debugging) Three system fan-packs

Operating systems
Supported and certified operating systems: Microsoft Windows Server Red Hat Enterprise Linux SUSE Linux Enterprise Server Canonical Ubuntu References: Complete list of available operating systems: OS Interoperability Guide.
