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.

3.4.1EXPANSION CABLING

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.
