2.3.1 SCU
The SCU is fixed on the S3700. Each S3700 has one SCU.
The SCU is responsible for packet switching and device management. It integrates multiple
functional modules, namely, the main control module, switching module, and interface module.
Main Control Module
The main control module implements the following functions:
l
Processing protocols
l
Functioning as an agent of the user to manage the system and monitor the system
performance according to instructions of the user, and report the running status of the device
to the user
l
Monitoring and maintaining the interface module and switching module on the SCU.
Switching Module
The switching module, also called the switching fabric, is responsible for packet exchange,
multicast replication, QoS scheduling, and access control on the interface module of the SCU.
The switching module adopts high performance ASIC chips to implement line-speed forwarding
and fast switching of data with different priorities.
Interface Module
The interface module provides Ethernet interfaces for accessing Ethernet services.
2.3.2 Power Supply
The S3700 can use either the DC power supply or the AC power supply.

2.3.3 Fan
The fans can work in the intelligent mode or forcible mode.
In the intelligent mode, the fans start to operate only when the environment temperature exceeds
a specified value.
The S3700-26C-HI supports the forcible mode.
2.3.4 Interface Card
The S3700HI switch supports the interface card for upstream services. The interface card
improves the networking flexibility, and provides the cost-effective and personalized solutions
to customers.
