FEA TURES
• Twisted-pair version lets you select
Category 5, 5e, or 6 cable.
• Fiberoptic versions available for duplex
multimode or duplex single-mode.
• Access video equipment locally and
remotely.
• Upgradable firmware.
• PS/2 cables and adapters are included.
• Each extender includes a local and
a remote unit.
OVERVIEW
Suppose you have a PS/2®CPU at one location, but need
dual access to it (from either a local or a remote PS/2
keyboard, DVI monitor, and PS/2 mouse). The ServSwitch
™
DVI/VGA Fiber CATx (twisted-pair), Multimode (fiber), or
Single-Mode (fiber) Extenders are ideal for any KVM
application that demands flexible video connections and
exceptional video quality. With these extenders, you get video
resolution at the local console of up to 1600 x 1200
for VGA or 1280 x 1024 for DVI.
A PS/2 console is defined as a PS/2 keyboard/video/mouse
combination. When the keyboard and mouse are being used
at one PS/2 console, the extender blocks access at the other
console until there is no keyboard or mouse activity for a
defined timeout period.
CATx twisted-pair cable is defined as either CAT5, CAT5e,
or CAT6. Extend the distance from your PC up to 300ft.
(91.4 m) using CATx cable and a CATx extender.
For greater distances between consoles and the CPU,
choose the fiber optic extender models. There’s one for
multimode and another for single-mode cable. The multimode
model lets you run 62.5/125-µm cable up to 650 ft. (198.1 m)
between local and remote units, or connect 50/125-µm cable
up to 1300 ft. (396.2 m). And by using fiber cable, you get all
its benefits, including immunity to electrical interference.
The single-mode version enables 9/125-µm connections
up to 6.25 mi. (10.1 km) apart.
All models include a local unit (transmitter) and a remote
unit (receiver). Connect the local unit to the computer’s CPU
or server directly with the included PS/2 cable, and attach the
KVM console to the remote unit.
DVI and VGA adapters are also included.
The extenders work best with DVI (Digital Visual Interface)
video displays. However, they also work with VGA displays,
too, with an adapter cable.
Diagnostic LEDs on both local and remote units tell you
link status, when the devices are ready, and when the units
detect a video signal or valid mode. There’s also an LED to
indicate communication errors.

Recognize any of these situations?
• You wait more than 30 minutes to get through
to a vendor’s tech support.
• The so-called “tech” can’t help you or gives you
the wrong answer.
• You don’t have a purchase order number and the
tech refuses to help you.
• It’s 9 p. m. and you need help, but your vendor’s
tech support line is closed.
According to a survey by Data Communications
magazine, 90% of network managers surveyed say
that getting the technical support they need is extremely
important when choosing a vendor. But even though
network managers pay anywhere from 10 to 20% of their
overall purchase price for a basic service and support
contract, the technical support and service they receive
falls far short of their expectations—and certainly isn’t
worth what they paid.
At Black Box, we guarantee the best value and the
best support. You can even consult our Technical Support
Experts before you buy if you need help selecting just
the right component for your application.
