Introduction

Introduction

Supported PSUs

The power supply system for the E9000 chassis consists of six PSUs. PSUs include DC and AC PSUs. When the E9000 is fully configured with PSUs, the power capping value of the chassis is 9000 W to 15000 W.

  • DC PSUs support the following rated input voltages:
    • –48 V DC to –60 V DC
    • 60 V DC to 400 V DC
  • AC PSUs support the following rated input voltages:
    • 100 V AC to 130 V AC (50 Hz to 60 Hz)
    • 200 V AC to 220 V AC (50 Hz to 60 Hz)
    • 220 V AC to 240 V AC (50 Hz to 60 Hz)

Figure 2-7 shows the installation positions and slot numbers of the PSUs in the chassis.

PSU Hibernation

If the chassis is running with low power, it does not need the redundant PSUs. The PSU hibernation feature sets redundant PSUs to hibernation mode based on the PSU configurations and current chassis power to save energy. The 2000 W, 2500 W, and 3000 W PSUs support hibernation at appropriate voltages.

The hibernation feature automatically sets redundant PSUs to hibernation mode. If the chassis power increases or a PSU exception occurs, the management software cancels hibernation mode and wakes up all hibernated PSUs. As the chassis power increases or decreases, the management software compares the sum of the rated power of all operating PSUs with the total power consumption of the entire chassis and automatically adjusts the number of hibernated PSUs based on the hibernation mode.

Parameter

Description

Hibernation

  • Enable: Enables the PSU hibernation function. If the parameter value is Enable, select a hibernation mode.
  • Disable: Disables the PSU hibernation function (disabled by default).

Hibernation mode

  • N+1: One backup PSU is required. For example, if a chassis is configured with six PSUs and only two PSUs are required to supply sufficient power to the entire chassis, the number of PSUs that can be hibernated is calculated as follows: 6 – (2 + 1) = 3
  • N+N: N backup PSUs are required. For example, if a chassis is configured with six PSUs and only two PSUs are required to supply sufficient power to the entire chassis, the number of PSUs that can be hibernated is calculated as follows: 6 – (2 + 2) = 2
NOTE:

The management module implements PSU hibernation based on 50% of the PSU power according to factors such as the PSU working efficiency, power conversion rate, and electrical safety.

For example, if the total required power of the server is 3000 W and six 3000 W PSUs are configured with each PSU consuming 1500 W, only two PSUs are required. If N+N PSU hibernation mode is used, two PSUs are working, two PSUs are standby, and the remaining two PSUs are hibernated.
