Chapter 1 Product Overview
1.1 Introduction
1.1.1 Introduction to S7500 Series Ethernet Switches
H3C S7500 Series Ethernet Switches (hereinafter referred to as the S7500 series) are
modular, large-capacity L2/L3 Ethernet switches that support wire-speed forwarding.
The S7500 series are designed for IP metropolitan area networks (MANs), large
enterprise networks, and campus networks.
Together with Huawei MA5200 Ethernet Access Management Systems, H3C
S3100/S3600/S5600/S9500 Series Ethernet Switches, and H3C series routers, the
S7500 series can provide comprehensive networking solutions for MANs and
enterprise networks.
Figure 1-1 S7500 series in MAN
The S7500 series support AC and DC power supply redundancy, and now include the
models S7502, S7503, S7506, and S7506R.
zThe S7502 provides one switching & routing processing unit (SRPU) slot and one
line processing unit (LPU) slot. Both the SRPU and LPU can provide high-density
service ports.
zThe S7503 provides one SRPU slot and three LPU slots.
zThe S7506 provides one SRPU slot and six LPU slots.
zThe S7506R provides two SRPU slots for redundancy backup and six LPU slots.

Note:
zRefer to H3C S7502 Ethernet Switch Installation Manual for detailed information
about the S7502.
zIn the later chapters, only the S7503, S7506, and S7506R are involved.
1.1.2 Introduction to Switching Engines
Switching engines, also known as SRPUs, are the core of the S7500 series, and
include the following models:
zSalience III (LS81SRPG)
zSalience III Plus (LS81SRPG1)
zSalience III Edge (LS81SRPG3)
An SRPU generally has the following functions:
zL2 and L3 data forwarding between LPUs
zRoute calculation
zLPU monitoring
zProcessing of monitoring signals of components such as the system power and
fans
Salience III series SRPUs provide a high packet forwarding rate and switching capacity.
Each SRPU provides four 1000Base-X SFP ports (only for Salience III and Salience III
Edge) and one hot-swappable CF card port. The CF card stores the log and host
version to facilitate online software upgrade.
1.2 Technical Specifications for SRPUs

[2]: Extendable.
[3]: Extendable up to 256 K.
1.3 Salience III Series SRPUs
Salience III series SRPUs include:
zSalience III: If load sharing is implemented on the S7506R, the switching capacity
can be up to 384 Gbps. It provides an XG high speed bus, supporting LPUs
applying an XG high speed bus.
zSalience III Plus: If load sharing is implemented on the S7506R, the switching
capacity can be up to 768 Gbps. It provides XG high speed bus, supporting LPUs
applying an XG high speed bus.
zSalience III Edge: The switching capacity is 96 Gbps.
The Salience III series SRPUs provide one console port, one 10Base-T /100Base-TX
port, four 1000Base-X-SFP ports (only for Salience III and Salience III Edge), and one
port for a hot-swappable CF card, which stores the host version to facilitate the online
software upgrade.
Note:
Both Salience III and Salience III Plus provide an XG high speed bus and support the
LPUs that adopt an XG high speed bus. However, they provide the high speed bus in
different ways. If a Salience III SRPU is used, it can provide the XG high speed bus only
for the LPUs in the last two slots of the switch. If a Salience III Plus SRPU is used, it can
provide the XG high speed bus for LPUs in all slots.
The following figures show the appearance of these three SRPU models.

Note:
zWhen two Salience III or Salience III Edge engines are used in an S7506R XGbus
chassis as the main and standby SRPUs, the first two SFP ports on both the active
and standby SRPUs can work in a redundancy mode so that the services will not
interrupted (the first two SFP ports are also active) during an active-standby
switchover.

XGbus is silkscreened on the S7500 series chassis (hereinafter referred to as the
S7500 XGbus). The backplane of the S7500 series supports XG high speed bus, and
thus can provide even higher switching capacity.
Depending on the input power, the chassis of the S7500 series can be divided into AC
chassis and DC chassis.
S7503:
zS7503-AC-XG-PoE: PoE-capable S7503 XGbus AC chassis
zS7503-DC-XG-PoE: PoE-capable S7503 XGbus AC chassis
S7506:
zS7506-AC-XG-PoE: PoE-capable S7506 XGbus AC chassis
zS7506-DC-XG-PoE: PoE-capable S7506 XGbus DC chassis
S7506R:
zS7506R-AC-XG-PoE: PoE-capable S7506R XGbus AC chassis
zS7506R-DC-XG-PoE: PoE-capable S7506R XGbus DC chassis
Note:
zThe S7500 series provide power to remote powered devices (PD) such as IP
phones and WLAN wireless access points (AP) by using PoE-capable cards and
power sourcing equipment (PSE).
zThe backplane, SRPU, power module, and fan tray are necessary components of
the S7500 series.

Caution:
zThe handle on the rear panel is used for removing or installing the rear panel of the
switch. It does not bear the weight of the whole switch.Thus, do not hold this handle
when handling or moving the switch. The same is true of the handles on the rear
panels of all the S7500 series.
zA filler panel is installed in the power module slot marked with NULL in Figure 1-6
and no power module can be inserted into it.
Each area is hot-swappable.
zIn the board area, there arefour horizontal slots. The topmost slot is for a required
SRPU and the other three are for optional LPUs.
zThe fan area is on the right of the chassis. The fan tray slot is vertical.
zThe power supply area is at the bottom of the chassis. The power modules work in
1+1 redundancy mode and they support dual AC or DC power supply. You can
select either AC power supply or DC power supply as required.
