2 1.1 Introduction Introduction to 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. 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. The S7503 provides one SRPU slot and three LPU slots. The S7506 provides one SRPU slot and six LPU slots. The S7506R provides two SRPU slots for redundancy backup and six LPU slots. 1-1

3 Refer to H3C S7502 Ethernet Switch for detailed information about the S7502. In the later chapters, only the S7503, S7506, and S7506R are involved Introduction to Switching Engines Switching engines, also known as SRPUs, are the core of the S7500 series, and include the following models: Salience III (LS81SRPG) Salience III Plus (LS81SRPG1) Salience III Edge (LS81SRPG3) An SRPU generally has the following functions: L2 and L3 data forwarding between LPUs Route calculation LPU monitoring 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. 1.2 Technical Specifications for SRPUs Table 1-1 Technical specifications for SRPUs Item Salience III Salience III Plus Salience III Edge Switching capacity 384 Gbps [1] 768 Gbps [1] 96 Gbps Packet forwarding rate 198 Mpps [1] 432 Mpps [1] 72 Mpps Number of VLANs 4 K 4 K 4 K MAC address table size 32 K [2] 32 K [2] 32 K IP address table size 64 K [3] 64 K [3] 64 K [1]: This is the switching capacity when load sharing is implemented by configuring two Salience III/Salience III plus engines on the S7506R. 1-2

[3]: Extendable up to 256 K. 1.3 Salience III Series SRPUs Salience III series SRPUs include: 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. 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. 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. 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. Figure 1-2 Salience III 1-3

Board LEDs SRPG: The LEDs of the SRPG show the status of the SRPU. LPU1, LPU2, LPU3 (LPU4, LPU5, LPU6): The LEDs of these LPUs respectively show the status of three LPUs (for the S7503), or six LPUs (for the S7506 or S7506R). Table 1-8 Description of board LEDs LED RUN (Green) ALM (Red) Description ON or OFF: The board is faulty or the board is not in position. Blinking (0.5 Hz): The board operates normally. OFF: The board operates normally or the board is not in position. ON: The board is faulty. If the RUN LED blinks fast, the board is booting but does not operate normally. During the initialization of the system, the ALM LED will be on for a while, but this does not mean that the board is faulty. II. Power LEDs (PWR1, PWR2 and PWR3) PWR1, PWR2 and PWR3: The LEDs of the PWR1, PWR2 and PWR3 respectively show the status of the three (AC or DC) power modules. Table 1-9 Description of the power LEDs LED OK (Green) FAIL (Red) Description ON: The power module operates normally. OFF: The power module is faulty or not in position. ON: The power module is faulty. OFF: The power module operates normally or is not in position. 1-10

12 If the FAIL LED on the S7503 is on, it is also possible that the power module is in position but the power switch is not turned on. III. Fan tray LEDs (FAN) FAN: The LEDs of the fan tray show the status of the fan tray. Table 1-10 Description of fan tray LEDs LED OK (Green) FAIL (Red) State description ON: The fan tray operates normally. OFF: The fan tray is faulty or the fan tray is not in position.

For the layout, see Figure 1-9. Each area is hot-swappable. In the board area, there are eight horizontal slots. The topmost two slots are for required SRPUs. The S7506R provides SRPU redundancy backup. The other six are for optional LPUs. The fan area is on the right of a chassis. The fan tray slot is vertical. The power module area is at the bottom of the chassis and contains three power module slots to implement 2+1 redundancy. You can select AC power modules for AC power input or DC power modules for DC power input as required. The power distribution area is at the chassis bottom near to the back panel. There is an AC power distribution box for AC power input or a DC power distribution box for DC power input. There are a 48 VDC power input terminal and a COM port (PoE management port) on the back of the PoE-capable S706R chassis Color of Board Edges The boards that can only serve as SRPUs of the S7503/S7506/S7506R have pink edges. The boards that can only serve as LPUs of the S7503/S7506/S7506R have purple edges. The boards that can not only serve as SPRUs of the S7502, but also LPUs of the S7503/S7506/S7506R have green edges. 1-17

19 For the S7500 series, a board with pink edges can be inserted only into a slot indicated by a pink area on the fan tray, and a board with purple or green edges can be inserted only into a slot indicated by a purple area Backplane The backplane of the S7500 series is located in the integrated chassis and implements high-speed data exchange and management & control signal exchange between SRPUs and LPUs. The backplane in the S7500 chassis supports XG high speed bus. The backplane has the following functions: Providing communication channels for signal exchange between boards Supporting online insertion and removal of boards Supporting slot auto-identification Connecting to the power modules to provide distributed power supply for LPUs and SRPUs Connecting to fan tray and power monitoring signal cables Supporting switchover between the active and standby SRPUs (only for the S7506R) (1) (2) (4) (3) (1) SRPU socket (2) Fan tray socket (3) PWR socket (4) LPU socket Figure 1-11 Backplane of the S

20 1.5.4 Power Supply The S7500 series support AC and DC power supply. You can select AC or DC power modules as required. Only one power module can ensure the normal operation of the S7503. However, the S7503 provides two power module slots to implement 1+1 redundancy backup. 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. The power modules of the S7500 series are hot swappable. 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 Have exactly the same dimensions and ports. Have exactly the same type of output connector in the same position. Not be inserted into one switch. Use their corresponding power distribution boxes. (3) (2) (1) (1) Captive screw (2) Front shell of power module (3) Air filter Figure 1-12 Power module 1-19

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 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 1-20

22 two DC power modules are equipped but only one input is connected, the SRPU displays alarm information for the unsupplied module. 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 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. 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 1-15 Specifications for DC power module Item Rated voltage range Input voltage range Maximum output power Specification 48 VDC to 60 VDC 36 VDC to 72 VDC 450 W 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 1-22

24 The S7500 series support a maximum PoE input power of 2400 W. If the PSE2500-A3 is used, one rectifier can supply 1250 W, two 2400 W, and three in 2+1 redundancy mode also 2400 W at an input voltage of 100 to 140 VAC. One rectifier can supply 2500 W at a voltage of 200 to 240 VAC and two power modules are required for redundancy backup. The S7500 series provide power through Ethernet electrical ports on the PoE-capable cards, with a maximum PoE distance of 100 m (328 ft.) 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.
