Chapter 1 Product Overview
1.1 General Information
1.1.1 Preface
Quidway S6500 Series Ethernet Switches, developed by Huawei Technologies, are
series of modularized wire speed Ethernet switches that operate at layer two/three, of
which S6503, S6506 and S6506 are intended to operate at the distribution layer of IP
metropolitan area networks (MANs) and at the core layer of small or medium sized
enterprise networks and campus area networks; S6502 is designed for the core layer of
small or midsize enterprise networks, the distribution layer and access layer of IP
MANs.
S6502 is a two-slot high-capacity cost-effective layer three Ethernet switch. It provides
high-density GE/FE ports, as well as modularized components that enable you to
configure flexibly according to your specific needs.

S6502 supports 1+1 redundant AC and DC power supplies. One of its slots is designed
for switching engine and the other for the LPU. Both of them can provide high-density
service ports.
1.1.2 Switching Engine
Switching engine (also known as SRPU) is the core component of a S6500 switch.
Currently, following types of switching engines are available on S6502:
LS81P12TE

Installation Manual

LS81T12PE
Generally the SRPU can provide these functions:
zForwarding L2/L3 data between LPUs, when connected to LPUs through the
backplane.
zManagement and route calculation. It can monitor and reset the LPU, upgrade
LPU software.
zProcessing monitoring signals on the power system and fans, which are
transferred through the backplane.
In addition to these functions, the SRPU of S6502 also can provide high-density service
ports:
zLS81P12TE: provides four 10/100/1000BASE-T ports and 12 ×1000BASE-X
(SFP) ports.
zLS81T12PE: provides 12 ×10/100/1000BASE-T port and four 1000BASE-X (SFP)
ports.

The front panel is occupied by the power supply modules, RESET button, COM port
(for PoE management), console port, 10Base-T/100Base-TX management port and its
status LED, fan LED, card status LED.
S6502 provides two horizontal slots, with the upper for SRPU and the lower for LPU.
The SRPU is mandatory, and the lower slot can hold many types of LPU cards.
Figure 1-6 illustrates the front panel of an S6502 switch, where the LS81P12TE is
inserted in slot 0 and LS81GT8UE in slot 1.
