Introduction
Overview
The KH2508 / KH2516 Cat 5 High Density KVM Switches give IT
administrators advanced control of multiple computers. Operators working at
up to two keyboard, monitor, and mouse (KVM) consoles can independently
and simultaneously take direct control of up to 8 or 16 computers in a single-
level installation, or up to 512 or 4096 KVM ports in a full three-level cascaded
switch installation. Cascading is achieved via dedicated RJ-45 cascade ports
and Cat 5e cabling.
The two KVM consoles belonging to the first-level KH2508 / KH2516 are able
to access all the computers on the installation – those that are directly
connected to the switch, as well as those that are cascaded. Where applicable,
one KVM console belonging to each cascaded KH2508 / KH2516 can access
the computers on the same, or lower level.
The KH2508 / KH2516 feature RJ-45 connectors and Cat 5e cable to link to
the computers. 1280 x 1024 @ 75Hz video signals can travel up to
40 m (130 feet), eliminating the need for KVM extenders. Utilizing PS/2 and
USB KVM adapter cables for the final linkup, the KH2508 / KH2516 permits
any combination of PCs, Macs, Sun computers, and serial devices to coexist on
the installation. Additionally, the use of RJ-45 connectors saves precious IT
real estate by allowing 8 or 16 KVM ports to reside in a single 1U housing.
Access to any computer connected to the installation is easily accomplished by
means of mouse-driven on-screen display (OSD) menus. A convenient Auto
Scan feature also permits automatic scanning and monitoring of the activities
of computers running on the installation one-by-one.
Setup is fast and easy – plugging cables into their appropriate ports is all that
is entailed. Because the KH2508 / KH2516 intercepts keyboard and mouse
input directly, there is no software to configure, and no need to get involved in
complex installation routines, or be concerned with incompatibility problems.
