1.1.1 Introduction
Edge-Core ES4700BD is a high performance routing switch that can be deployed as
a core layer device for campus and enterprise networks, or an aggregation device for IP
metropolitan area networks (MAN).
ES4704BD provides 4 slots, 3 or 2 of which are interface module slots. ES4710BD
provides 10 slots, 8 of which are interface module slots. ES4700BD supports various
types of line cards, and can seamlessly support network interfaces from 100Mb, 1000Mb
to 10Gb Ethernet. Featuring functions such as policy-based routing, IPv6, and load
balance, it is capable of flexibly meeting the different requirements of complex customer
environments. Furthermore, ES4700BD allows redundancy for management modules,
power supply. It supports AC-input power supplies, with hot-swapping support for cards,
power supplies and fans. The working temperature of all cards can be monitored in
real-time, offering carrier-class reliability.
1.1.2 Features
„
Advanced Architecture
The design for the ES4700BD Series core routing switch is fully distributed
architecture. With a powerful ASIC chip dedicated to high-speed route lookup and traffic
forwarding through “longest-match” and “packet-by-packet” mode, the switch ensures
enhanced forwarding performance and scalability. ES4700BD can effectively block
network viruses such as "Code red”, "Worm.Blaster” and "Worm.Sasser” etc, and is a
great choice for large scale networks with busy transactions and complex traffic, therefore
meeting the metro-trend for Ethernet.
„
Interfaces
ES4704BD provides 4 slots, and can be configured in Primary controller-Primary
Backup mode with 2 management modules and 2 network modules, or Single controller
mode with 1 management module and 3 network modules.
ES4710BD provides 10 slots, and can be configured in Primary controller-Primary
Backup mode with 2 management modules and 8 network modules, or Single controller
mode with 1 management module and 8 network modules.

Carrier Class Reliability
To meet the strict requirements for device reliability of carrier class networks and to
ensure 100% uptime of network cores, the design of ES4700BD enables redundancy for
all critical parts, such as power supply, management modules and network links, all
modules are also hot-swappable, and working temperatures of all parts are monitored
real-time.
