Hardware Information

Hardware Information

For the version mappings, appearance and structure, port description, indicator description, power supply configuration, heat dissipation, and specifications of the S5700, see the Chassis section in the S5700 Series Switches Hardware Description.

Figure 4-1 shows the logical structure of hardware modules in the switch.

Hardware modules of the switch refer to the interface card, Switch Control Unit (SCU), power supply, and fan.

Figure 4-1  Logical structure of hardware modules

SCU

The S5700 switches are equipped with SCUs. Each switch has one SCU.

The SCU provides packet switching and device management. It integrates the main control module, switching module, and interface module.

Main Control Module
The main control module provides the following functions:
  • Processes protocol packets.
  • Manages the system and monitors the system performance according to instructions of the user, and reports the device running status to the user.
  • Monitors and maintains the interface module and switching module.
Switching Module

The switching module (switching fabric) is responsible for packet exchange, multicast replication, QoS scheduling, and access control on the interface module of the SCU.

The switching module uses high-performance chips to provide line-rate forwarding and fast switching of data with different priorities.

Interface Module

The interface module provides Ethernet interfaces for Ethernet service transmission.

Power Supply

For details about power supply configurations on S5700-LI-BAT, see the Battery Modules section in the S5700 Series Switches Hardware Description.

For details about power supply configurations on other S5700 switches, see the Power Modules section in the S5700 Series Switches Hardware Description.

Cards

The S5700 supports service and stack cards. Service cards allow for flexible networking and provide cost-effective customized solutions. Stack cards connect multiple switches into one logical switch, which implements on-demand expansion, reduces costs, simplifies management, and improves network reliability.

For details about cards supported by the S5700, see the Cards section in the S5700 Series Switches Hardware Description.

Fan Modules

For details about fan modules in different models, see "Heat Dissipation" under Chassis in the S5700 Series Switches Hardware Description.

Pluggable Modules for Interfaces

For specifications of various pluggable modules for interfaces, see the Pluggable Modules for Interfaces section in the S5700 Series Switches Hardware Description.
