The Cisco 800 series of routers is designed to create compact computer networks with a high level of protection. This review will consider the communicator model 857-K9. This network device is included in this line of routers, and it is on its example that this series of routers will be considered.
Package
The delivery list of the device in question consists of the following main items:
- Router with one removable antenna installed on it.
- Console cable for router setup.
- Power cable to implement the power supply of this network system.
- Documentation set.
- Digital media containing software and user manual.
This is a typical configuration of the communicator of this series. It is sufficient and allows you to set up and start using such equipment without the slightest problem.
Settings and connection of the network device
The maximum information transfer rate in the wireless segment, which canto provide such a switch is 54 Mbps. In this case, the coverage range can reach 100 meters. The wired part of the LAN can include a maximum of three computers, in which case the exchange rate can increase up to 100 Mbps. Also, one port is used to exchange data with the provider's equipment.
Therefore, connecting the Cisco 800 consists of two main steps. The first of them is the switching of the power cable with the power supply system. And the second is the supply of a twisted pair cable from the provider and its installation in the corresponding port of the device. The RAM of this router is 64 MB. The built-in storage is the same size.
Cost
A very expensive device is any Cisco 800 router. At the moment, the 857-K9 router costs 23,000 - 24,000 rubles. If it were a budget router, then its price would be sky-high. But in this case, we are dealing with a specialized network solution. Its key feature is a high level of protection of transmitted information. Accordingly, its cost is much higher than that of a conventional household router.
When is the best time to use? Setting
The 851-K9 is best used in office environments. At the same time, increased requirements are put forward for the protection of transmitted information. This router runs an operating system called Cisco IOS and has specialized software. With the help of the latter, the maximum level is ensuredprotection of transmitted information. Also, the number of computing devices connected to such a network node should not exceed 10.
Setting up the Cisco 800 is quite a complicated operation. To implement it, you need to know the Cisco IOS command system. Therefore, it is best to entrust its implementation to a professional. It is very problematic for a poorly trained specialist to cope with it.
Reviews
Networking experts are very positive about the Cisco 800 series routers. The router considered in this review is no exception. It has a high level of reliability and stability. Also, the security of the LAN when using it does not cause any complaints. The only disadvantage of any such router is the high cost. But such advanced switches cannot have a low price by default. And the Cisco brand speaks for itself.
Conclusion
The Cisco 800 series of switches has an office specialization. Moreover, it makes sense to buy such a router only when the transmitted information needs an increased level of protection. It also requires a qualified person who can set up and maintain such equipment. In all other cases, the use of such a router is impractical.
