Power Supply

X4 device Power Supply System

Overview

The X4 device supports DC, AC, and high-voltage DC power supply modes. The device can be connected to up to two power sources through power entry modules (PEMs). Each power module (PM) has two power inputs, and they convert the power supplied to the PEM to power the entire device.

  • If only one power source is available in the equipment room, connect the PEM's terminal blocks or power sockets A1 to A6 or B1 to B6 to the power source.
  • If two power sources are available in the equipment room:
    • In AC or high-voltage DC powered installation scenarios, you are advised to connect power sockets A1 to A6 to one power source, and power sockets B1 to B6 to the other power source. By default, power sockets A1 to A6 are in use, and B1 to B6 are on standby. If A1 to A6 fail to supply power, B1 to B6 take over.
      If the power sources need to work in load balancing mode, connect as follows:
      • Connect power sockets A1 to A3 and B4 to B6 to one power source.
      • Connect power sockets A4 to A6 and B1 to B3 to the other power source.

    • In DC powered installation scenarios, connect terminal blocks A1 to A6 to one power source, and terminal blocks B1 to B6 to the other power source. If the two power sources have different voltages, the one with a higher voltage provides a higher current.
    • In AC and high-voltage DC powered installation scenarios, the 220 V AC power supply is used by default. If the 220 V AC power supply fails, the system automatically switches to the high-voltage DC power supply.
  • Requirements for the power supply system of a customer's cabinet: The output power of two power sources must be greater than the maximum input power of the device.

Components

As shown in Figure 1-13, the power supply units of the X4 device are located at the top of the chassis. The power supply units are PMs and power switches at the front of the chassis, and a PEM at the rear of the chassis. Table 1-25 describes the functions of each unit.

Description

1

PM

Converts the power supplied to a PEM, and then powers the entire device through the power backplane and busbar.

2

Power switch

Controls the power output of PMs. The two power switches back each other up. When one or both of them are turned on, the power output of PMs is enabled.

NOTICE:

To ensure reliability, both power switches must be turned on when the device is running.

3

PEM

Connects to a power source.

One PEM can be connected to two power sources through its power sockets or terminal blocks. This design implements 1+1 power supply redundancy, ensuring that the device is not powered off if one power source in the equipment room fails.

PM and PEM Applications

The X4 device supports multiple power supply scenarios, which vary according to the installed PEM and PMs. Table 1-26 describes the power supply scenarios and PEM/PM applications.

PM and PEM Application Principles

The PEM is integrated into the chassis and does not need to be configured onsite. Do not attempt to remove or install the PEM onsite. PMs can be configured based on the chassis's overall power consumption, providing flexible power supply.

DC PMs and AC & high-voltage DC PMs of the X4 device can work in N+1 redundancy mode, in which N indicates the number of PMs configured based on the chassis's actual power consumption. The maximum power supply capability of one chassis is equal to the sum of the maximum output power of N PMs installed in the chassis. In N+1 redundancy mode, N PMs supply power to the chassis, and one PM works as a backup.

Taking a DC PM with 2200 W output power is used as an example, if PMs are configured according to the N+1 redundancy mechanism (that is, one PM is added on top of the number of required PMs), the value of N x 2200 W must be greater than the chassis's power consumption, as described in Table 1-27.

Power Supply Architecture

  • DC power supply

    The X4 device must be equipped with one DC PEM. This PEM has 12 terminal blocks, every six of which are connected to one power source. Each DC PM has two power inputs, each of which comes from one power source in the equipment room. The DC PM converts and outputs the power to the power backplane, allowing the two power sources to back up each other. Figure 1-14 shows the DC power supply architecture of the X4 device.

    Figure 1-14 DC power supply architecture of the X4 device
  • AC & high-voltage DC power supply

    The X4 device must be equipped with one AC & high-voltage DC PEM. This PEM has 12 power sockets, every six of which are connected to one power source. Each AC & high-voltage DC PM has two power inputs, each of which comes from one power source in the equipment room. The AC & high-voltage DC PM converts and outputs the power to the power backplane, allowing the two power sources to back each other up.

    The X4 device can be directly connected to a power source or indirectly connected one through a power distribution unit (PDU). Directly connecting a device to a power source uses cable connections similar to those in the DC power supply mode, and is not described here. The following describes the power supply architecture in the scenario where a device is indirectly connected to a power source through a PDU.

    The NetEngine 8000 X series devices supports two types of PDUs:
    • AC PDU: Each AC PDU provides one power input and six power outputs.
    • High-voltage DC PDU: Each high-voltage DC PDU provides two power inputs and eight power outputs. Each input corresponds to four outputs.

    AC, high-voltage DC, and AC & high-voltage DC hybrid power supplies are supported. Figure 1-15, Figure 1-16, and Figure 1-17 show the power supply architectures of the three modes.

Overview

The X16 device supports DC, AC, and high-voltage DC power supply modes. The device can be connected to up to two power sources through power entry modules (PEMs). Each power module (PM) has two power inputs, and they convert the power supplied to the PEM to power the entire device.

  • If only one power source is available in the equipment room, connect the PEM's terminal blocks or power sockets A1 to A20 or B1 to B20 to the power source.
  • If two power sources are available in the equipment room:
    • In AC or high-voltage DC powered installation scenarios, you are advised to connect power sockets A1 to A20 to one power source, and power sockets B1 to B20 to the other power source. By default, power sockets A1 to A20 are in use, and B1 to B20 are on standby. If A1 to A20 fail to supply power, B1 to B20 take over.
      If the power sources need to work in load balancing mode, connect as follows:
      • Connect power sockets A1 to A10 and B11 to B20 to one power source.
      • Connect power sockets A11 to A20 and B1 to B10 to the other power source.

    • In DC powered installation scenarios, connect terminal blocks A1 to A20 to one power source, and terminal blocks B1 to B20 to the other power source. If the two power sources have different voltages, the one with a higher voltage provides a higher current.
    • In AC and high-voltage DC powered installation scenarios, the 220 V AC power supply is used by default. If the 220 V AC power supply fails, the system automatically switches to the high-voltage DC power supply.
  • Requirements for the power supply system of a customer's cabinet: The output power of two power sources must be greater than the maximum input power of the device.

PM and PEM Application Principles

The PEM is integrated into the chassis and does not need to be configured onsite. Do not attempt to remove or install the PEM onsite. PMs can be configured based on the chassis's overall power consumption, providing flexible power supply.

DC PMs and AC & high-voltage DC PMs of the X16 device can work in N+1 redundancy mode, in which N indicates the number of PMs configured based on the chassis's actual power consumption. The maximum power supply capability of one chassis is equal to the sum of the maximum output power of N PMs installed in the chassis. In N+1 redundancy mode, N PMs supply power to the chassis, and one PM works as a backup.

Taking a DC PM with 2200 W output power is used as an example, if PMs are configured according to the N+1 redundancy mechanism (that is, one PM is added on top of the number of required PMs), the value of N x 2200 W must be greater than the chassis's power consumption, as described in Table 1-43.

Power Supply Architecture

  • DC power supply

    The X16 device must be equipped with two DC PEMs. Each PEM has 20 terminal blocks, every 10 of which are connected to one power source. Each DC PM has two inputs, each of which comes from one power source in the equipment room. The DC PM converts the power and outputs the power to the power backplane, allowing the two power sources to back up each other. Figure 1-32 shows the DC power supply architecture of the X16 device.

    Figure 1-32 DC power supply architecture of the X16 device
  • AC & high-voltage DC power supply

    The X16 device must be equipped with two AC & high-voltage DC PEMs. Each PEM has 20 power sockets, every 10 of which are connected to one power source. Each AC & high-voltage DC PM has two power inputs, each of which comes from one power source in the equipment room. The AC & high-voltage DC PM converts and outputs the power to the power backplane, allowing the two power sources to back each other up.

    The X16 device can be directly connected to a power source or indirectly connected one through a power distribution unit (PDU). Directly connecting a device to a power source uses cable connections similar to those in the DC power supply mode, and is not described here. The following describes the power supply architecture in the scenario where a device is indirectly connected to a power source through a PDU.

    NetEngine 8000 X series deviceses provide two types of PDUs:
    • AC PDU: Each AC PDU provides one power input and six power outputs.
    • High-voltage DC PDU: Each high-voltage DC PDU provides two power inputs and eight power outputs. Each input corresponds to four outputs.

    AC, high-voltage DC, and AC & high-voltage DC hybrid power supplies are supported. Figure 1-33, Figure 1-34, and Figure 1-35 show the power supply architectures of the three modes.

X16 device AC&High-Voltage DC PEM

Overview

X16 device AC&high-voltage DC PEMs connect the X16 device to AC&high-voltage DC power sources. The PEMs are pre-installed by default, and cannot be removed, installed, or replaced onsite.

The X16 device and X8 device use the same AC&high-voltage DC PEM. The difference is that the X16 device needs to be configured with two AC&high-voltage DC PEMs.

PAH-3000WA (3000W Dual Inputs AC&HVDC Power Module)

Overview

Table 1-50 Basic information about the PAH-3000WA
Item Details
Description 3000W Dual Inputs AC&HVDC Power Module
Part Number 02312JEA
Model PAH-3000WA
Remarks Power modules can be configured based on the overall power consumption of the device to flexibly supply power.
  • After the external power is input to PMs through PEMs, the PMs output the power to the power supply backplane. Each PM has two inputs, which are from power supply areas A and B, respectively. The PM combines the two power inputs and outputs one.
  • The power module supports AC and HVDC mixed power supply:
    • If the two power supplies have different power systems, the AC power supply is preferentially used as the active power supply (to ensure the highest power supply efficiency), and the high-voltage DC power supply is used as the standby power supply.
    • If the two power supplies have the same power system, power supply A is preferentially used as the active power supply, and power supply B is used as the standby power supply.
  1. Ensure that the upstream input and circuit breakers on areas A and B meet the power supply requirements of the entire system. Otherwise, the power supply of the entire system may be affected if one area cannot provide all the power required by the entire system.
  2. If the active power supply is abnormal, the system automatically switches to the standby power supply. When the active power supply recovers, the system automatically switches back to the active power supply.
  3. When the fan of the Power Module is faulty, the Power Module hiccup occurs every three minutes. The Power Module attempts to establish output again. At this time, the Output Indicator is On and the Alarm Indicator is Off. If the fault persists, the Output Indicator is Off and the Alarm Indicator is On 30 seconds later.
