Black Box SW741A-R3 用户手册

Right: If you need to share access to a large number of CPUs, think about putting in
a Matrix ServSwitch daisychain made up of units with Expansion Modules. The
switch’s expansion port comes with a Terminator Module installed, but once you
swap in an Expansion Module, you’ll be able to attach one Matrix ServSwitch to
another.

Above: Here are the two basic options for designing your daisychain layout:.

• If both of your users are on one chassis, use the bus topology (left).

• If your users are located on different chassis, use the ring topology (right).*

*It is always important to keep in mind that only one user at a time can use the bus that interconnects daisychained Matrix ServSwitch units.

For example, if any user on KVM 1 selects a CPU attached to a switch other than his own, no other KVM 1 user can select a CPU.

Right: The basic elements of a single Matrix
ServSwitch setup are shown: connections to a
user station (keyboard, monitor, and mouse), a
CPU, and AC power. IBM PC equipment is
shown, but the principles will be similar for
all equipment types. Connectors will vary
depending on the types of equipment you
are installing.
