Chapter 1 Product Overview

1.1 Introduction

1.1.1 Introduction to S7500 Series Ethernet Switches

H3C S7500 Series Ethernet Switches (hereinaf ter ref erred to as th e S7500 seri es) 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.

z The 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.

z The S7503 provides one SRPU slot and three LPU slots. z The S7506 provides one SRPU slot and six LPU slots. z The S7506R provides two SRPU slots for redundancy backup and six LPU slots.

 Note:

z Refer to H3C S7502 Ethernet Switch Installation Manual for detailed information

about the S7502.

z In 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:

z Salience III (LS81SRPG) z Salience III Plus (LS81SRPG1) z Salience III Edge (LS81SRPG3)

An SRPU generally has the following functions:

z L2 and L3 data forwarding between LPUs z Route calculation z LPU monitoring z Processing 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.

1.3 Salience III Series SRPUs

Salience III series SRPUs include:

z Salience 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.

z Salience 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.

z Salience 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.

1.5.4 Power Supply

 Note:

z The S7500 series support AC and DC power supply. You can select AC or DC

power modules as required.

z Only one power module can ensure the normal operation of the S7503. However,

the S7503 provides two power module slots to implem ent 1+1 redundancy backup.

z Two power modules can ensure the normal operation of the S7506 or the S7506R.

However, the S7506 or S7506R provides three power module slots to implement 2+1 redundancy backup.

z The power modules of the S7500 series are hot swappable. z Although the S7503 provides three power module slots, no power module can be

inserted in the power module slot marked with NULL. Therefore, the PWR3 LED is always off.

AC power modules and DC power modules of the S7500 series must

z Have exactly the same dimensions and ports. z Have exactly the same type of output connector in the same position. z Not be inserted into one switch. z Use their corresponding power distribution boxes.

two DC power modules are equipped but only one input is connected, the SRPU displays alarm information for the unsupplied module.

z The AC power distribution box of the S7503 supports two power inputs, each of

which has a separate power switch. One input can only maintain the normal operation of the corresponding AC power module. Only when the two inputs are connected, the two AC power modules can work in 1+1 redundancy mode. When two AC power modules are equipped but only one input is connected, the SRPU displays alarm information for the unsupplied module.

2) S7506 and S7506R

z The DC power distribution box of the S7506 and S7506R supports two power

inputs, each of which has a separate power switch. Either of the two inputs can maintain the normal operation of the three DC power modules at the same time. When one input is connected, the three DC power modules can work in 2+1 redundancy mode. When two inputs are connected, the DC powe r inputs can work in 1+1 redundancy mode.

z The AC power distribution box of the S7506 and S7506R supports two power

inputs, each of which has a separate power switch. Either of the two inputs can maintain the normal operation of the three AC power modules at the same time. When only one input is connected, the three AC power modules can work in 2+1 redundancy mode. When two inputs are connected, th e AC power inputs can work in 1+1 redundancy mode.
