The "love story" between single boards and switches: How to identify the support relationship between them?

Have you ever had a question: Which switch supports this board?

Or you may have a question: What boards does this switch support?

In this chapter, the editor will explain to you thoroughly: what is the support relationship between the single board and the switch.

Which switch supports this board?

There is always a moment when a question pops up in the sky: Which series of switches does this board support? For the main control board and interface board, you can make a preliminary judgment based on the first two digits of the board name:

In fact, you can use this very powerful query tool "Hardware Query" to perfectly solve the query of various support relationships. Here is a demonstration of how to use it.

1. Press "Parts Information Query"

You can manually enter or select a specific product series, and the supported versions and device models will be automatically filtered out, as shown below:

You can continue to refine the query information according to the filtering conditions listed below. For example, if you want to query the boards supported by S12704: click "S12704" and "Board" respectively, and then click the "Query" button. The results listed are the boards supported by S12704:

Click the BOM code of a board to jump to the detailed introduction page of the board. For example, click the first 03030RPE:

2. Query by support status

3. You can enter the BOM code, external model or board name silk screen of the component to query a specific component

For example, if you want to query a card ES5D21X04S01, enter the model number to get the relevant information of the card, including which devices it is supported on, etc.:

What types of boards does this switch support?

There are two main types of boards supported by switches:

• Main control board: The brain of the switch, managing and controlling the work of each interface board and data forwarding, etc.
• Switching board: provides high-speed, non-blocking data channels to realize service switching functions between various service modules.
• Interface board: specifically used for data reception and transmission, etc.
• Value-added service board: specially designed for specific services such as firewall, AC function, NAT, etc.

What interface boards does the switch support?

The interface board is mainly used to exchange (receive and forward) data, and the speed of data exchange is bound to be of most concern to everyone. When exchanging data, the interface board follows a variety of rules, so the features and specifications supported by the interface board are also of most concern to everyone. Just as highways are divided into expressways, national highways, provincial highways, etc., according to the speed, the interface board is divided into 100GE, 40GE, 10GE, 25GE, GE, and FE interface boards. The detailed classification and support relationship are as follows:

The table only lists the interface boards with the largest number of interfaces

Just as roads have dedicated lanes and mixed lanes, interface boards can be divided into F series, S series, E series, B series, X series, etc. according to their functions, mainly due to differences in functional characteristics and software specifications. S7700 supports S series, E series, F series, B series boards, and X series, among which:

S7900 supports E3E series, E3S series, E3L series, and X3S series.

The S9700 supports S series, E series, F series, B series, X series, and POS interface boards, including:

The S12700 supports the S series, E series, and X series.

The S12700E supports the X series, including the X5E, X5S, X6E, X6H, X6S, and AK (X5EK and X6EK) interface boards.

What are the value-added service boards supported by the switch?

Just as roads need traffic police and monitoring, networks need security features such as firewalls, IPsec, intrusion detection, and anti-virus. Just as roads need traffic restrictions and traffic lights, networks need specific service features such as load balancing, NAT (Network Address Translation), and NetStream. The editor lists the value-added service boards supported by the switch as follows:

• SPU board: provides load balancing, firewall, NAT, IPSec (IP Security), NetStream and other service functions for the switch.
• OSP board: can be installed with operating system and application software to complete the functions of application software. Currently, the software available for installation is IPS application software.
• ACU board: This board can be regarded as an independent AC device and is hung on the switch as a wireless access controller.
• NGFW firewall board: can quickly and flexibly integrate firewall, NAT, VPN and other security functions for IP networks.
• IPS board: can quickly and flexibly integrate intrusion prevention, anti-virus, DDoS attack defense and other security functions for IP networks.
