Acceptance of network equipment

Equipment acceptance is divided into two parts, hardware acceptance and software acceptance.

Hardware acceptance, according to the specific model on the purchase order, compare the serial number, product model and quantity of the hardware equipment. Some devices may need to be looked at in the system, such as show versions. Formal supply, there should be the original factory proof, all whether it is low-end, or high-end, the best, must be certified by the original factory, so as to put an end to repair, parallel imports, or even fake goods

Software acceptance, if you buy a product with E, then pay attention to the version of IOS. Although Cisco's IOS can pass through a switch of the same class, I still feel unwilling to spend money on a pirated IOS.

Equipment acceptance, mainly to prevent budget swapping models, less accessories. So, in the case of no less accessories, it is necessary to call 800 according to the serial number and check whether it is true or false. It costs a lot to make a phone call.
