SERVSWITCH™ AND SERVSWITCH ULTRA™

You can add submasters to your ServSwitch system as you need them. For each

submaster you add to the system, you add as many ports as are on that submaster,

minus the one port on each master “above” it that’s now occupied. Refer to

Figure 3-2 on the next page:

• Connecting one 4-port submaster Serv unit to a 4-port master ServSwitch (top

view) gives you a total of 7 ports: 4 on the submaster and another 3 (4 minus

the one that the submaster is attached to) on the master.

• Connecting four 4-port submaster Serv units to a 4-port master ServSwitch

(bottom view) gives you a total of 16 ports, 4 on each submaster. (All 4 ports

on the master are now occupied.)

When you use Matrix ServSwitches as submasters, the setup is a little more compli-

cated. Refer to Figure 3-3 on page 28: Connecting two 4-port Matrix ServSwitch

submasters to an 8-port ServSwitch master gives you a total of 14 ports on that

master. (Each of the masters in Figure 3-3 can access 14 ports, but while both

masters share CPUs 1 through 8, CPUs 9 through 14 on either master can only be

accessed by the monitors, keyboards, and mice on that master. Note that when we

say that CPUs 1 through 8 are “shared,” we mean that they can be accessed by

either master at different times, not by both masters simultaneously.) Adding a

third 4-port submaster unit would give you a total of 17 ports, and so on. (To reach

all of the CPUs in cascaded systems like this, you must set Maximum Ports, Width,

and Units properly on the master unit; see Sections 4.3.8 through 4.3.10.)

EQUIREMENTS FOR

XPANSION

To connect submaster units to a ServSwitch, you’ll need one ServSwitch to

ServSwitch Expansion Cable for each submaster unit. You will also need a CPU

Adapter Cable for each CPU you will be connecting to the submaster’s CPU ports.

(Remember that one MKM Adapter Cable is required to connect the master unit

to your keyboard, monitor, and mouse.) See Sections 3.2.2 through 3.2.4.

3.3.2 I

NSTALLING A

ASCADE

Laying out your ServSwitch system prior to installation will make the installation

process go more smoothly. It will also help you to keep the port-selection numbers

you’ll use in keyboard commands in a rational sequence. Figure 3-2 on the next

page illustrates the proper layout and numbering of your submasters and CPUs.

Keep these restrictions in mind when you design your ServSwitch system:

• If you use original Serv cables, the total distance from any CPU to any monitor,

keyboard, and mouse should not exceed 40 ft. (12.2 m). Depending on your

application, this distance might be less; see Section 4.1.3.
