Six key points for SMEs to purchase Poe switches
Small and medium enterprises switch to buy six points
Switches should be selected according to the principles and needs of LAN formation, but should also pay attention to the following points when meeting the requirements:
1, pay attention to the appropriate size. Now the LAN construction, in addition to functional and practical, the layout of the LAN structure is reasonable, but also everyone should consider the issue. To this end, LAN is now often used control cabinet, to all kinds of network equipment for overall control and unified management. In this case, the switches we choose must match the control cabinet in size. To do this, we‘d better choose the 19 inch rack switch that meets the rack standard. This type of switch conforms to the unified industrial standard and can be easily installed in the cabinet for easy stacking, cascading, management and maintenance. If you do not have the above requirements, desktop switches have higher performance price ratios.
2, the exchange rate is faster. The choice of the transmission speed of the switch is based on the different communication requirements of different users. Now the general LAN is 10M Ethernet, and then taking into account the needs of upgrading, 10M/100M adaptive switch has become the mainstream of LAN switches, and even can become a standard switching equipment for local area networks. However, with the continuous improvement of communication requirements and the increasing data traffic, 100M switches, as well as Gigabit switches and even Wan switches, are beginning to emerge. However, the switching performance of the switches with different switching speeds is also very large, and it is not necessary for us to separate from the actual data transmission information to pursue the high-speed switching performance of the switches. If a small LAN, or ordinary Internet use, as long as the choice of 10M/100M adaptive switch can be, because this type of exchange price is not too high, and the performance and speed can meet the needs of the users. I learned from some network products dealers, currently in the workgroup and departmental switches, 10/100Mbps adaptive switch is also selling the most fire. 100M and 1000M switches are usually a good choice for users of high-end applications, and to some extent, it solves the problem of frequency bandwidth between servers and servers. Those Gigabit switches and even millions of switches are used for backbone construction, and are not normally considered by our average users.
3, port number should be enough to upgrade in the future. LAN requirements for network communication now more and more high, network speed is getting faster, so we‘d better buy a switch, to take into account the scalable enough to select appropriate port number. Now the number of switch ports on the common market, there are 8, 12, 16, 24, 48, and several different port number in the price also have some differences, if the cost savings from the point of view, select the appropriate number of ports switch is a link can not be ignored. Now the 24 port switch on the market is selling the most fire. We establish the users in LAN, should first plan may contain many nodes of good LAN, then according to the node number selection switch; but from the application point of view, the 24 switches with 8 ports and 16 port switches have greater room for expansion, expand the scale of LAN is very convenient. Therefore, in the actual process of networking, we should make a compromise to consider these factors according to the actual situation.
4, according to the use of requirements, choose the right brand. According to each user‘s actual economic capacity, because a good brand switch may be higher than the price of several common brand switches on the price, why is there such a big difference? Good brand switch really high quality, stable performance and strong function, after the user buy back, found it is more practical. In the current switch market, 3Com Cisco, has been in the mobile switch market, but the brand‘s exchange price is relatively high, the price of a switch to domestic switches than a same bandwidth price is much higher, so the brand should be the backbone network of the first large switch. If only the department or workgroup LAN, I suggest that you go to the best choice of Hong Xiang, Burghardt Shida, Lenovo -Dlink and TP-Link, the price is very affordable for ordinary brand switch, which Lenovo -Dlink due to better brand awareness and complete product line, the exchange price is higher than other grade products with about 10% higher. If your enterprise has sufficient funds, and the network requirements are higher, then from the mature point of view of technology, foreign brands are still preferred. However, foreign brands of switches in case of failure, need to change or after-sales maintenance, may be more time-consuming than domestic switches, as long as a few months are likely to occur.
5, management control function to be powerful. Because the network switch belongs to the more expensive equipment, even if the investment is not a place, but also try to do three years behind, which requires us to select the switch, to switch control technology into account management. Switch management control technology mainly in the switch to support the intelligent management technology, because of this technology, the network administrator can reduce the maintenance workload of network management; second performance in the switch can support a variety of information flow, IP/IPX routing function now some new switches can support third layers, with this function we can use the switch, when necessary to achieve the router
