You’ll need three-to-one CPU KVM-extension cables (product code EHN230) to
connect the Rackmount Extender Local Hub’s DB25 composite CPU ports to the
CPUs’ keyboard, mouse, and video ports. Order one such cable for each CPU (or
one for each CPU video card if you’re attaching CPUs with multiple video
outputs). As mentioned on the previous page, you might also need port adapters if
any of your CPUs have PC/AT type ports.
To attach the DB9 CPU-port serial connectors of a KVM/Serial or
KVM/Serial/Audio Extender Local Hub to the CPUs’ serial ports, you’ll need DB9
male-to-female serial-extension cables such as product code EDN12H-MF. Order
one of these cables for each CPU whose serial I/O you’re extending.
To attach the 3.5-mm CPU-port audio connectors of a KVM/Serial/Audio
Extender Local Hub to the CPUs’ audio ports, you’ll need standard 3.5-mm stereo
audio-extension cables such as product code EJ110-0010.

You would do this to extend the distance you can run from the KVM switch to a
monitor, a keyboard, a mouse, and possibly serial and/or audio devices. (You
could also do this to extend the distance you can run between two cascaded
switches, but for this to work, each switch
must
be either a ServSwitch Jr. or one of
the ServSwitch family models with DB25 composite interfaces listed in
Section 4.2.2.B
.)
Which cable(s) you’ll need will depend on what type of user ports the switch
model has, as detailed in the following three subsections.
4.2.2.A Switches Whose User Ports Are a Set of Separate Interfaces
The user ports of some ServSwitch family KVM switches are a set of separate
interfaces: Each user port consists of separate interfaces/connectors for video,
keyboard, mouse, and (on the ServSwitch Multi only) serial and audio
communication. At the time of this writing, some of the important ServSwitch
family models in this category are:
• ServSwitch™ Duo
• ServSwitch™ Wizard, Wizard LP, Wizard MP, and Wizard Pro
• ServSwitch™ Jr.
• Personal ServSwitch™
• ServSelect™
• ServSwitch™ Multi Base Unit (“local console” user port only)
