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.

System fan
  • Supported fan types:

    • Standard fan (60 x 60 x 38 mm, single-rotor, 24000 RPM)

    • Performance fan (60 x 60 x 56 mm, dual-rotor, 20000 RPM)

    • Ultra 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

    • Two processors or middle/rear drive bays: six hot-swap system fans

Note

  • 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.

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.

Power policy for power supply units

Following is one or two 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.
