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.

l           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.

l           The S7503 provides one SRPU slot and three LPU slots.

l           The S7506 provides one SRPU slot and six LPU slots.

l           The S7506R provides two SRPU slots for redundancy backup and six LPU slots.

 

 

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:

l           Salience III (LS81SRPG)

l           Salience III Plus (LS81SRPG1)

l           Salience III Edge (LS81SRPG3)

An SRPU generally has the following functions:

l           L2 and L3 data forwarding between LPUs

l           Route calculation

l           LPU monitoring

l           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.

I. Introduction to power distribution box

The power distribution box is mainly used for filtering, current make/break, and current shunt. The AC power distribution box and DC power distribution box have the same dimensions.

1)         S7503

l           The DC power distribution box of the S7503 supports two power inputs, each of which has a separate power switch. One input can only support the normal operation of the corresponding DC power module. Only when two inputs are connected, the two DC power modules can work in 1+1 redundancy mode. When two DC power modules are equipped but only one input is connected, the SRPU displays alarm information for the unsupplied module.

l           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

l           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 power inputs can work in 1+1  redundancy mode.

l           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, the AC power inputs can work in 1+1 redundancy mode.

Table 1-13 AC power distribution boxes of S7506 and S7506R

AC power distribution box	Input voltage range	Applicable chassis
110-120V/220-240V, dual-input, dual-switch	110-120 V/220-240 VAC; 50 Hz or 60 Hz; 9.0A/5.0 A	S7500-AC-XG-PoE

 

II. AC power module

For AC power supply, you should use AC power modules and AC power distribution boxes.

Table 1-14 Specifications for AC power module

Item	Specification
Rated voltage range	100 VAC to 240 VAC, 50 Hz or 60 Hz
Input voltage range	90 VAC to 264 VAC, 50 Hz or 60 Hz
Maximum output power	450 W

 

III. DC power module

For DC power supply, you should use DC power modules and DC power distribution boxes.

Table 1-15 Specifications for DC power module

Item	Specification
Rated voltage range	–48 VDC to –60 VDC
Input voltage range	–36 VDC to –72 VDC
Maximum output power	450 W

 

1.5.5  PoE Power Supply

The S7500 series support power-over-Ethernet (PoE). Equipped with power sourcing equipment (PSE) and PoE-capable boards, the S7500 series can provide –48 VDC power to remote powered devices (PDs) such as IP Phones, WLAN APs, and network cameras through twisted pairs. Choose a chassis that supports PoE if PoE is needed.

Figure 1-15 Power sourcing equipment–PSE2500-A3

 

 

1.5.6  Fan Tray

The fan tray is located on the right side of the S7500 series. The fan tray is directly connected to the backplane through a connector. All fan fault signals flow to the backplane and then the backplane sends them to the SRPU for processing. The fan tray is hot swappable.

Fan trays of the S7506R, S7503, and S7506 are slightly different. Fan trays of the S7506R and S7503 are fixed by screws, while the fan tray of the S7506 is fixed by two locks.

l           The fan trays of the S7503 and S7506R are fixed by screws.

l           The fan tray of the S7506 is fixed by two locks.

Follow these steps to remove the fan tray from the S7503 chassis or S7506R chassis:

1)         Remove the screws from the fan tray.

2)         Grasp the edge of the fan tray and gently pull it out.

Follow these steps to remove the fan tray from the S7506 chassis:

1)         Simutaneously pull the two locks outward to release them.

2)         Gently pull the fan tray out.
