It is a misconception that using third party transceivers will void your switch warranty. The truth is that they do not. And most importantly, it is against the law for the OEM to say yes. The Magnuson-Moss Federal Trade Commission Act protects consumers from this mistake! Under this act consumer warranties cannot include tie-in sales. In other words, manufacturers cannot force you to buy their transceivers to keep your warranty valid exchange.

The vendors such as Cisco, HP, 3Com and many others buy their transceivers from third party manufacturers, for example Cozlink.com. Then add your logo and label for them and sell them at high margins. Cozlink manufactures and sells directly by ourselves, so we can keep costs low while maintaining the highest standards.
