ME60-X16A Power Supply System

ME60-X16A Power Supply System

Overview

Introduction to Modules

As shown in Figure 8-26, the ME60-X16A power system is located at the top of the chassis. The main components are the PMs, PMUs, and switches in the front of the chassis and the PEMs at the rear of the chassis. Table 8-50 describes the functions of each module.

Description

1

PM

Converts the power supplied to the PEM and supplies power to the entire device through the backplane.

2

PMU

The PMU is used to manage the power module and the power access module, monitor their working status, and report the status to the host.

3

Switch

Controls the power output of PMs. The two switches back up each other. When one or two switches are in the ON state, the power output of PMs is enabled.

4

PEM

Connects to the external power supply system and supplies power to the ME60-X16A. The right and left parts of the PEM correspond to power supply areas A and B, respectively. Power supply areas A and B are two power supply systems with different sources. The system connects to different power supply systems, ensuring that the system remains powered-on if one power supply system fails.

Power Module Mappings

The ME60-X16A supports multiple power supply scenarios, which vary in the installed PEMs and PMs. Table 8-51 lists the mappings between power supply scenarios and PEMs/PMs.

The two inputs are from power supply areas A and B, respectively. In this manner, power supply areas A and B back up each other. A maximum of 16 PMs can be configured based on the N+1 backup mechanism. Figure 8-27 and Table 8-52 show the mappings between PEMs and PMs.

    The ME60-X16A supports N+N backup for PMs. The power supply system supports the backup of power supply areas A and B on the user side. Every N power modules are connected to one power supply area, ensuring that the entire system can work properly if any power supply area fails.

    The ME60-X16A has four PEMs. Each PEM has four inputs. There are altogether 16 inputs (8 inputs in each of area A and area B). Each PM has two inputs. The two inputs are from power supply areas A and B, respectively. In this manner, power supply areas A and B back up each other. A maximum of 16 PMs can achieve a maximum of 8+8 backup.

Power Supply Principles

PEMs are integrated into the chassis and do not need to be configured onsite. Do not remove and install PEMs onsite. PMs can be configured based on the overall power consumption of the device to flexibly supply power.

  • N+1(-48 V DC)

    A DC PM has output power of 2200 W. Use the N+1 PM backup mechanism as an example. N+1 PMs are configured for power supply, with N being the number of PMs required for the power consumption of the entire device. The value of N x 2200 W must be greater than the overall power consumption of the entire device. Table 8-54 shows the details.

    NOTE:
    If PMs are not fully configured, power cables are routed only for the PEM interfaces whose corresponding PMs are installed. To facilitate the deployment of new power cables during capacity expansion of PMs, you are advised to configure the PMs from the top down and leave a filler panel in the position where no PM is not installed.

  • N+N(AC/HVDC)

    A DC PM has output power of 3000 W. PMs are configured based on the N+N backup mechanism. To be specific, N (N>=1) PMs are configured for each of area A and area B on the user side. The value of N x 3000 W must be greater than the power consumption of the entire system. Table 8-55 shows the details.

    NOTE:
    If PMs are not fully configured, power cables are routed only for the PEM interfaces whose corresponding PMs are installed. To facilitate the deployment of new power cables during capacity expansion of PMs, you are advised to configure the PMs from the top down and leave a filler panel in the position where no PM is not installed.

System Power Supply Architecture

ME60-X16A uses the non-partitioned power supply architecture. ME60-X16A backplane has one area, which houses two power inputs converged on backplane.

-48 V DC Power Supply

As shown in Figure 8-29, the ME60-X16A has four PEMs. Each PEM has eight inputs. There are altogether 32 inputs (16 inputs on each of power supply source A and power supply source B). Each PM has two inputs. The two inputs are from power supply sources A and B, respectively. The PM converts the power and outputs the power to the power supply backplane. In this manner, power supply sources A and B back up each other A maximum of 16 PMs can be configured based on the N+1 backup mechanism.

Figure 8-29 DC power supply

AC and HVDC Power Supply

As shown in Figure 8-30, after the external power is input to PMs through PEMs, the PMs convert power and output the power to the power supply backplane. Each PEM provides four channels of power inputs (with two partitioned into power supply source A and two partitioned into power supply source B) for four PMs. There are 16 PMs on the device.

Figure 8-30 HVDC and AC power supply

DC PM

The external power is input to PMs through PEMs, the PMs perform current equalization and regulation and output the power to the power supply backplane.

    Note the derating requirements of protection components when using protection components such as fuses and circuit breakers. If the current of a PDF is less than 63 A, it cannot supply power to the device. In this case, reconstruct power supply in the equipment room.
  • If the front-end PDF does not provide enough power inputs, configure a PDB that meets the following requirements:
    • The current of each channel output by the DC PDB is not less than 63 A.
    • Double-channel backup is used.
    • The input current is not less than the sum of current of its connected output lines.
