The NTI PRIMUX Zero-U KVM Switch System (PRIMUX-UZR) allows you to control up to 64 computers without consuming rack space. The switch frees up valuable space by eliminating large KVM switchboxes and bulky hard-to-manage coax cables.

The PRIMUX system consists of two components: the User Station that connect to a keyboard, monitor, and mouse, and Host Adapter that connect to a server. Up to 64 Host Adapters can by daisy-chained together, providing user access to up to 64 servers. The User Stations and Host Adapters can be located as far as 1,000 feet from each other via CAT5 UTP cable.

NTI PRIMUX-UZR Features & Applications:

  • A single, inexpensive CAT5/5e/6 UTP cable replaces bulky KVM cables.
  • Ideal for hazardous/unsecured environments. User station can be located up to 1000 feet from servers.
  • Easy to install and use with plug-and-play functionality.
  • Provides a simple daisy-chained wiring configuration.
