System Overview
4.2.1
KVM Extender - Structure
A pair of KVM extenders consists of 2 KVM extender modules, each with at least one CPU extender
module and at least one CON extender module. The various extender modules are installed respectively in
a Draco vario chassis (2-slot, 4-slot, or 6-slot) on the CPU side (CPU Unit) and console side (CON Unit).
With 2-slot, 4-slot and 6-slot chassis add-on modules are placed above an extender, with 21-slot chassis,
add-on modules are placed to the right of an extender module.
The assignment of the extenders or add-on modules can be recognized by the article number:
• Extender module or add-on module for the CPU Unit: L4XX (L = Local)
• Extender module or add-on module for the CON Unit: R4XX (R = Remote)
An add-on module can contain up to 2 independent function parts (part A and B), one on the left and one
on the right, see Fig. 1.

KVM Extender - Numbering of the Chassis Slots
The numbering of the slots in the chassis runs from bottom left to top right (2-/4-/6-slot chassis) and from
left to right (21-slot chassis). The slot numbering is relevant for the placement of an SNMP module in a
backplane chassis (see example) or a USB 2.0 stand-alone module in chassis without backplane (slot 2).
