I did not face any major challenges, but the only thing is that D-Link has to invest in training technicians or engineers who install their products. They have to keep training them. D-Link can offer free training, or maybe even if they are charged, it's some fair charge. That way, D-Link encourages many technicians to take that training. And when the team has trained technicians or trained engineers, then it becomes very easy to install the devices and put them in the network. The solution integrates very well with our existing network infrastructure. The initial setup is straightforward. But, again, I will insist: If it is handled by trained personnel, then you find that the integration and installation are easy. But when people try to install the switches or the solutions and they do not have the technical know-how, then it becomes a challenge. People start saying that it's not a good solution, that they are not working. Yet, it is the technician who does not know how to handle them.
