16800 Series Full Duplex Huawei Cloud Engine Switches CE16808A - B05

Huawei CE16808A - B05 CloudEngine 16800 Series Switches

Overview

The CloudEngine 16808 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.

Components

The power supply units of the CloudEngine 16808 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. describes the functions of each unit.

Component

Description

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

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.

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.

Power Supply Architecture

DC power supply
The CloudEngine 16808 must be equipped with one DC PEM. This PEM has 20 terminal blocks, every 10 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 3-11 shows the DC power supply architecture of the CloudEngine 16808.

AC & high-voltage DC power supply
The CloudEngine 16808 must be equipped with one AC & high-voltage DC PEM. This 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 CloudEngine 16808 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 CloudEngine 16800 seriesswitches 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.
