The ServSwitch 8-Port KVM switch is used to connect 2 independent KVM users to 8 PC-only or PC and Sun CPUs. Need to expand and add more CPUs? You will find a Matrix ServSwitch is the perfect multiuser KVM switch. With it, each user has total and independent access to any of the connected CPUs or servers on the system. For even more convenience, you can add a local monitor to each switch location. The Matrix can also accommodate an Expansion Module, which can be ordered separately. With Expansion Modules installed, you can daisychain Matrix chassis to reach larger or more widely separated groups of CPUs.
