The product is very easy to install. When it comes to OmniSwitch 6200, OmniSwitch 6300, or OmniSwitch 6600, you can install it in an hour and a half quickly without any problem implementing the configuration, but it's not stable. When it comes to OmniSwitch 6400, OmniSwitch 6800, or OmniSwitch 9700, mostly the tools are limited in terms of the protocol. The switch cannot be managed to manage the power of our ethernet. For example, if we connect an iPhone to the switch, 740 watts will be required, but after six months, someone will discover that the port doesn't work anymore. Even if we configure it to push the power of a port, it will not work. It's not really, it's not, it's not work. At the same time, the problem was that the tool was very old, like Alcatel OmniPCX Enterprise PABX system. In Alcatel, there are only two types of architecture, the old and new ones. For example, on the outside, if there is a need for 24 ports to be implemented on telephony, then we implement less than that number to connect to the end of the phone, which is a very serious problem that is not resolved by the product.
