Best Practice Solution Guide

4.1       Preparation

4.1.1      Preparation before Installation

Preparation before installation

To ensure the installation successfully, make sure the installation site meets the requirements including ventilation, temperature, humidity, sanitary, power, fiber, cable .etc

For Detail information ,see 《hardware installation and reference guide》 of corresponding products , such as 《RG-S8600E Series Switch Hardware Installation and Reference Guide,V1.10》

On the other hand, double confirm following important infomation ahead of schedule:

1. The network topology, configuration, IP routing information, user scale, traffic information and running status of current production network.

2. Equipment list and pre-sale solution.

3. Customer's requirements and corresponding features

4. The campatibility with current devices, like STP, AP with switches of other vendors

5. Current link and interface status including optical connector, fiber etc.

6. Design the Network and acquire customer's agreement

7. Customer's network verification requirements

8. Customer's cut over plan requirements

9. Customer's acceptance inspection requirements

4.1.2      Check Switch Software/Hardware

Check software

This figure shows how to display soft and hardware version

Software selection rules:：

1. We suggest you to update the new switch to the latest firmware

2. We suggest you to update the existing switch to the latest firmware also if they're running steady

3. For detail technical specification , see corresponding product configuration guide ,or visit our service portal http://case.ruijienetworks.com/

Note：

Confirm whether the project is a "expansion network" or "new network"

1) If the project is a expansion network ,focus on the compatibility as following :

Expansion module/line card

For detail infomation , see "Hardware Supported"  in corresponding product 《release notes》

Expansion switch

Focus on the campatibility of different protols (especially MSTP) between Ruijie and other vendor.Do a full validation before implementation

2) If the project is a new network

Determine whether the current/latest firmware supports customer's requirement , see configuration guide of corresponding product

3)Read 《release notes》and double confirm the matters need attention

Check hardware：

Take S8600E series switches as example (see 《RG-S8600E Series Switch Hardware Installation and Reference Guide》)

1. M8600E-CM：

2. M8600E-24GT20SFP4XS-ED LED

3. M8600E-48GT-ED LED

4. M8600E-48GT-EF LED

4.2        Best Practic Scenario

4.2.1      Education

Dual core using VSU

I. Requirement

1. Core swtich： Configure two S8600E chassis swithes as VSU , and connect VSU to WAN zone with double uplinks

2. Server farm：Connect some Servers and storage  to data center switch S6220 and S6220 is also gateway for servers and storage .You can also connect other servers that have equiped with double NICs to VSU with double links

3. Aggregation switch：For Layer 3 Aggregation switches , they are user gateway and run OSPF  .Connect a aggregation switch to two VSU members independently . For Layer 2 aggregation switch , connect them  to two VSU members   independently ,and VSU is the user gateway.

II. Network Topology

III. Common requirements and features

Select features below base on requirements:

IV. Optional optimization

Select optional optimization below base on requirements:

V. Verification

1. For single feature verification, see verification method in each corresponding chapter

2. For total network running status, see Appendix
