CHAPTER 3: Installation and Preconfiguration
3.4 Daisychaining Matrix ServSwitches
Chaining multiple Matrix ServSwitches together adds capacity for more computers
and, optionally, more user stations. When you plan a daisychained system, keep in
mind that Switches attach to each other:
• From output to input.
• In a bus or ring topology.
• With one or two cables.
Each Switch must have its “starting computer” configuration parameter set
correctly before you attach it to other Switches. See Section 3.6 for how to do this.
Also be aware that if you are using the ring topology (see Section 3.4.2), you must
set the RING/BUS jumper on the Expansion Modules in two adjacent Switches to
RING (see Section E.1 of Appendix E).
NOTE
If you’re very careful, you can attach Matrix ServSwitches to daisychains
of ServSwitch Affinity (product code KV13xA) chassis. See the “Mixed
Chains” section of the Affinity manual for details, and please call Black
Box Technical Support before installing such a mixed daisychain.
3.4.1 E XPANSION C ABLING
You’ll use Expansion Cables (product codes KV140010, etc.) to interconnect
Matrix ServSwitches. These Expansion Cables, which are all exactly alike except for
their lengths, carry computer and KVM signals from one Switch’s Expansion-
Module output ports to another’s input ports. Each Expansion Module must be
installed in the blank-plated slot on the left end of the Switch chassis’ rear panel.
The Module’s input and output ports are labeled IN and OUT, as shown in
Figure 3-2. The IN port receives video signals from other Switches; the OUT port
transmits video signals to other Switches.
The maximum distance that Expansion Cable can be run between any two
Switches is 100 ft. (30.5 m). See Appendix B for cable and Extender product codes.
