S7703 PoE  Hardware Description

Introduction

Huawei S7703 Switch is one of the S7700 series smart switches, and the S7700 series switches are smart routing switches designed for next-generation enterprise networks. The S7700 series switches can offer voice, video, and data services, helping enterprises build routing and switching integrated end-to-end networks.

The S7700 series design is based on Huawei’s intelligent multi-layer switching technology to provide intelligent service optimization methods, such as MPLS VPN, traffic analysis, comprehensive HQoS policies, controllable multicast, load balancing, and security, in addition to high-performance Layer 2 to Layer 4 switching services. The S7700 also features super scalability and reliability.

The S7703 PoE chassis provides 3 LPU slots, 2 MCU slots, and 3 power supply slots.

The S7703 PoE chassis provides three power supply slots: PWR1, PWR2, and PWR3, which support DC and AC power modules.

The S7703 PoE chassis supports two redundancy modes of power modules: N+1, and N+0. You can run the set power backup-mode command to configure the backup mode of power modules. By default, the power supply redundancy mode is automatic redundancy. That is, the power module roles are automatically determined based on the power and number of power modules.

The power modules of the S7703 PoE chassis have the following roles:
  • M: indicates a master power module that is supplying power. When the backup mode of power modules is N+N or N+1, N power modules are of the master role.
  • S: indicates a standby power module. When the backup mode of power modules is N+1, one power module is of the standby role.
  • A: indicates a power module that is always supplying power. When the backup mode of power modules is N+0, N power modules are of the A role.

After the power supply redundancy mode is configured, run the display power command to view the power module roles.

1. Three of the following service cards can be installed:

 

  • Open Service Platform Unit
  • 100M Interface Card
  • 1000M Interface Card
  • GE/10GE Interface Card
  • 10GE Interface Card
  • 40GE Interface Card
  • 40GE/100GE Interface Card
  • 100GE Interface Card

    NOTE:

    The cards supported by a switch depend on the software version. For details, see Info-finder.

 2. Two MPUs 3. A pair of mounting brackets

 

NOTE:

The mounting brackets are used to secure the chassis in the cabinet.
4. Three power modules

 

  • 800 W AC Power Module
  • 2200 W AC Power Module
  • 2200 W DC Power Module
  • 3000 W AC Power Module

NOTE:

For details, see Power Module.

 5. Front ESD jack

 

NOTE:

The ground terminal of an ESD wrist strap can be inserted into this jack. The ESD wrist strap can provide ESD protection when the chassis is reliably grounded.

 6. Cable management frames

 

NOTE:

Cable management frames are used to route cables.

1. One Fan Module 2. Ground screw

 

NOTE:

The ground screw is used to ground the chassis.

 3. Rear ESD jack

 

NOTE:

The ground terminal of an ESD wrist strap can be inserted into this jack. The ESD wrist strap can provide ESD protection when the chassis is reliably grounded.
4. Air filter

 

NOTE:

The air filter prevents dust from entering the chassis.
