Network cabling materials, the way the company cabies the network

The 1 you envision is okay.

However, for management purposes, it is best to purchase a manageable switch, and then manage the two switches in trunk mode in a unified manner. If the internal environment is not very demanding on management, buy a fool's one.

Buy a wireless router with high power, large coverage area, and preferably a manageable fat AP. Of course, the cheap skinny AP you said can also meet your requirements, but the management is nothing.

Most of the cables are still amp or Langke.

Behind the switch, whether manageable or unmanageable, can transfer data to each other, you just need to set it up.

1, the connection method is no problem, yes, it will not affect the network speed of those 20 computers 2, there is no need for this.

4. You can choose wireless routing, but it is better to change the antenna with a stronger signal, but it is a bit dangerous to cover 400 square meters, because you are a company, there must be a wall in the middle, it is recommended to cover with 2 wireless APs.

5, 5 types of line choose 400-500 a box of price, the brand does not need to be considered, because there are too many brands, you have to care about the diameter of the core, whether it is not, skin and workmanship.

6. Yes, as long as it is in the same LAN, not only in the same switch, if you don't understand, please add questions, and wish you a happy Mid-Autumn Festival.

Cabling Considerations:

1. The most common wiring method of floor wiring, making full use of the space under the floor, pay attention to water leakage, rodent infestation and heat dissipation under the floor, and also ensure that the corresponding wiring holes (including floor and trunking) are dug under each cabinet.

2. Ceiling wiring is especially suitable for computer rooms that often need wiring, in this way, the ceiling contains a variety of power wiring, weak current wiring, and the corresponding wiring holes (including floor and trunking) are dug above each cabinet, of course, we should also pay attention to water leakage, rodent damage and heat dissipation. The specific wiring content includes: power wiring, weak current wiring and ground wiring.

Among them, the power wiring and weak current wiring are placed in the metal wiring slot, and the specific metal slot size can be considered according to the amount of wire and consider a certain room for development (generally 100 50 or 50 50). The distance between the power trunking and the weak trunking should be maintained at least 5 cm and cannot cross each other to prevent electromagnetic interference between each other.

1) Power wiring: When the power wiring is carried out in the decoration of the new computer room, it should be arranged according to the layout of the entire computer room and the capacity of UPS, and the corresponding power socket should be arranged near each cabinet and equipment in the planning, and the capacity of the socket should be determined according to the power of the access equipment, and leave a certain redundancy, generally 10A or 15A.

2) Weak current wiring: weak current wiring mainly includes coaxial thin cables, five types of network cables and ** wires, etc., when wiring, attention should be paid to the corresponding cables behind each cabinet and equipment, and should consider the future development needs, all kinds of cables should be divided into categories and bundled with nylon braided tape.

3. Grounding wiring: Since the new computer room is full of high-performance computers and network equipment, there should be strict requirements for grounding; Grounding is also an important measure to eliminate common impedance, prevent capacitive coupling interference, protect the safety of equipment and personnel, and ensure the stable and reliable operation of computer systems. The copper bar for signal grounding should be arranged under the floor of the computer room for various grounding needs in the computer room, and the copper bar is then connected to the weak signal grounding system there in the form of a special line.

The first floor is too general, and I don't know what it means to be on the second floor, in fact, you don't have to ask on the Internet, you find a supplier, and others will help you figure it out The specific amount of materials should be based on your on-site requirements and system operation requirements.

(1) Networking scheme: Adopt centralized medium-sized office LAN hardware scheme (2) Required hardware:

1 backbone switch: 1000 Mbps, requires a large-capacity switching backplane, adopts a modular chassis design, supports multiple rates and media, and supports SNMP and other network management protocols.

4 aggregation layer switches: 100 1000 Mbit/s, support SNMP and other network management protocols, and can increase access port density by stacking or adding modules.

Server: 100 1000Mbps network card, the number of network cards depends on the need: 10 100Mbps adaptive type.

There are several Category 5e UTP twisted pairs.

3) Networking method:

The network center uses super five twisted pair cables to establish a 1000base-t high-speed network between each floor, the aggregation layer uses 10 100Mbps switching to the desktop, the network center uses a gigabit backbone switch with high port density, and the server installs a 100 1000Mbps adaptive network card.

With a bus network, you only need to be able to access the Internet, and you don't have high requirements for speed.

As long as there is a strong performance file server, switch, router, network cable and hub, connector, splitter and other network hardware that meet the length of IEEE requirements.

After networking, the network security and flexibility are high, and the overall economy is low.

If you have 70 computers running at the same time, it makes sense to have a slower internet connection.

In the wiring project, it is mainly used in: bridge frame, conduit, light and dark bottom box, optical cable, copper cable, distribution box, cabinet, wiring module, terminal jumper, grounding bar, terminal block, etc.

First of all, determine the location of the computer room, generally the length of the network cable wiring is not more than 100 meters, it is best to choose the middle of the second floor, so that the wiring to each floor is slightly simpler, if there are many points, consider setting up a computer room on each floor.

Determine how many stations and how many points there are in a station, for example, a station needs a network, a printer.

Select the router, convert the optical fiber to RJ45 crystal head, and then connect to the router, set up the Internet by the router (you can set multiple public IPs), and then connect to the switch from the router, choose the network switch according to the number of points, the general commonly used DLINK or TP on the line, cheap, 48 ports, according to your number, no two 48 or three 48 strung together. The router can choose Huawei, H3C, **fair, easy to use, you can use Cisco if you have money and nowhere to spend. You can also add an Internet behavior manager, which can control the Internet speed and chat software.

If you want to save money, you can get a sea spider soft route, build an outdated old desktop, install a dual network card, and brush a system.

According to the number of points, choose the switch, the external line is selected according to your own needs, and the small company has 8 or 16 external lines.

Integrated wiring is a more complex project, four floors, wiring and equipment is not a decimal, must find a few professional companies to come up with a plan, report, so that you can understand more, the first aspect can also be cut down, in addition to monitoring these are also considered.

It is recommended to find a professional weak current engineering company for consultation!
