    • One VGA connector

    • Two USB 3.2 Gen1 (5 Gbps) connectors

      Note
      The lower USB connector at the rear functions as a USB 2.0 connector with XCC system management when there are no USB connectors at the front.

    • One XCC system management port (10/100/1000 Mbps RJ-45)

    • Two or four Ethernet connectors on each OCP module (optional)

Note
The maximum video resolution is 1920 x 1200 at 60 Hz.
Network
  • OCP module

    • The server features two OCP slots at the rear.

    • The installation priority of OCP slots in configurations with two processors is as follows:

      • configurations with only one OCP module: A x8 OCP module is installed in OCP slot 1; a x16 OCP module is installed in OCP slot 2.

      • configurations with two OCP modules: OCP slot 1 > OCP slot 2; x8 > x16

    • Both OCP slots are of x8 lanes as default, which can be upgraded to x16 lanes by using OCP cables in some configurations. For the cable routing of OCP modules with x16 connection, see Internal cable routing.

Electrical input and power policy

Electrical input for power supply units

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

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.
