Chapter 3 Product Overview
3.1 Introduction
H3C S7500 Series Ethernet Switches (hereinafter referred to as the S7500 series) are
a series of wire-speed Layer 2/3 Ethernet switching products with modular architecture
and high-capacity. Among this series, S7503, S7506 and S7506R are oriented to the
aggregation layer of IP metropolitan area networks (MANs) and the core layer of small-
and medium-sized enterprise networks and campus networks; and S7502 is oriented to
the aggregation and access layers of IP MANs and the core layer of small- and
medium-sized networks. The S7500 series provide powerful switching capability and
increase network availability; they have good scalability, high performance and
powerful network control ability.

Chapter 4 Networking Applications
The high-capacity, Layer 2/3 S7500 Series Ethernet Switches are mainly designed for
IP MANs, large-sized enterprise networks and campus networks. They can serve as
aggregation switches to play important role in MANs, or serve as core switches in
enterprise or campus networks. This series, together with the H3C
S3100/S3600/S5600/S9500 series and Huawei's MA5200 Ethernet access
management system, allows for comprehensive solutions for MAN and enterprise
networking.
The following sections describe several typical networking applications of the S7500
series.
4.1 Application in a MAN
Typically, an S7500 series switch can be used at the aggregation layer in a MAN. In
upstream direction, the switch is connected to a Layer 3 switch (for example, a H3C
S9500 series routing switch) or a GSR (Gigabit switching router) in the backbone
network through a GE link across long/ultra-long haul dark fiber cable (you can also use
multi-GE Trunk to increase upstream bandwidth). In downstream direction, the switch is
connected to the egress Layer 2/3 Ethernet switches (for example, H3C
S3100/3600/S7500 series switches) in LANs through GE ports across long/ultra-long
haul dark fiber cables (you can also use multi-GE Trunk to increase downstream
bandwidth).
Figure 4-1 Application in a MAN

4.2 Application in a Small/Medium-Sized Enterprise Network
Typically, an S7500 series switch can be used at the backbone layer in a
small/medium-sized enterprise network. The switch is connected to its neighboring
devices as follows: In the downstream direction, the switch is connected to the Layer
2/3 Ethernet switches (for example, H3C S3100/S3600 series switches) of workgroups
or directly connected to user's workstations through GE/FE optical or electrical ports; it
is connected to other floors/buildings through GE optical ports (long- or short-haul) or
multi-GE Trunks; and it is connected to server groups through GE/FE electrical ports. In
the upstream direction, it is connected to a router through a 10/100 Mbps electrical port.
Figure 4-2 Application in a small/medium-sized enterprise network
4.3 Application in a Large-Sized Campus Network
Typically, an S7500 series can be used at the aggregation or backbone layer in a
large-sized campus network. In this case, it is often deployed in cabling room or center
office. In the downstream direction, the switch is connected to the
workgroup/campus-level Layer 2/3 Ethernet switches (H3C S3100/S3600 series
switches) through GE/FE optical or electrical ports. In the upstream direction, it is
connected to a backbone Ethernet switch or a router through a GE optical/electrical
port.

Figure 4-3 Application in a large-sized campus network
4.4 PoE Application
Through the GE/FE electrical ports on a PoE-supported card, an S7500 series switch
can supply power to PoE-supported PDs (powered devices, such as wireless WLAN
APs, IP phones and corridor switches) across twisted pairs.
