SMART CAT5 SWITCH – 108/116
2. Introduction
Access and control multiple multi-platform computers from one Keyboard Video
Mouse (KVM) console with the Smart CAT5 Switch (Smart CAT5) system. The
Smart CAT5 comes in 108 and 116 models. Connect up to 8 computers to the 108
model, and up to 16 to the 116 model.
The Smart CAT5 is based on Minicom’s innovative ROC technology in which each
computer/ server is directly connected to the switch via RIC on Cable (ROC) using
standard CAT5 cable at a distance of up to 30m/99ft in a star configuration. The
system also works with Minicom’s RICCs using standard CAT5 cable up to 10m/33ft.
The system can contain a mixture of ROCS and RICCs. No external power is needed
at the remote ROC/RICCs.
2.1 Features
Hot-Swap - disconnect and reconnect computers without rebooting
Scan-mode operation with variable time interval
1U Rack mountable
Operate the system using an On Screen Display (OSD) or Control software or
front panel push buttons or keyboard hotkeys
Create multi-level cascade arrangements. For example by cascading the Smart
CAT5 116, connect up to up to 256 computers in the system
The computers can be placed up to 10m/33ft from the Smart CAT5
Multi-platform — supports PS/2, SUN, and USB computers/servers
2.2 System components
The Smart CAT5 system consists of:
Smart CAT5 Switch 108 or 116
Remote Interface Connection cables (RICCs) – PS/2, SUN, USB

3. Connecting the Smart CAT5 system
Each computer/ server is directly connected to the Smart CAT5 via theappropriate
ROC or RICC using CAT5 cable in a star configuration. The system can contain a
mixture of RoCs and RICCs. No external power is needed at the remote ROC/RICCs.
The ROC/RICCs draw their power from the computer’s keyboard port (ROC/RICC
PS/2, SUN) or from the USB port (ROC/RICC USB). The figures below illustrate the
ROC PS/2 and ROC USB.

3.1 Connecting a ROC/RICC PS/2
The connections for ROC/RICC PS/2 are exactly the same. Figure 6 illustrates the
RICC PS/2.
You can connect the ROC/RICC PS/2to a powered on computer, but it must be in the
following order:
1. Connect the Mouse connector to the computer’s Mouse port.
2. Connect the Keyboard connector to the computer’s Keyboard port.
3. Connect the Screen connector to the computer’s Video port.
Failure to connect in the above order while the server is running, may lead to the
mouse malfunctioning until the server is rebooted.

3.6.1 Avoiding general rack mounting problems
Elevated operating ambient temperature
The operating ambient temperature of the rack environment may be greater than the
room ambient when installing into a closed or multi-unit rack assembly. So install the
equipment in an environment compatible with the maximum rated ambient
temperature.
Reduced airflow
Install the equipment in a rack in such a way that the amount of airflow required for
safe operation is not compromised.
Mechanical loading
Mount the equipment in the rack in such a way that a hazardous condition is not
achieved due to uneven mechanical loading.
Circuit overloading
When connecting the equipment to the supply circuit, consider the effect that
overloading of circuits might have on over-current protection and supply wiring.
Reliable earthing of rack-mounted equipment should be maintained. Give attention to
supply connections other than direct connections to the branch circuit (e.g. use of
power strips).
3.6.2 Rack mounting the Smart CAT5
The Smart CAT5 comes with screw holes on the side for easy rack mounting, see
figure below.
Screw holes for bracket
Figure 9 Screw holes for rack mounting
Use the L-shaped brackets and screws provided to mount the Smart CAT5 on a server
rack as illustrated below. The length of the screws used for connecting the brackets to
the Smart CAT5 unit must not exceed 5 mm.

3.6.3 Rack mounting the RICCs
You can attach the RICCs to a server rack or computer using the Velcro strips
provided. Or connect it using the bracket provided.

3.6.4 Cascading Smart CAT5 switches
You can cascade the Smart CAT5 system. You do so by connecting the lower level
Smart CAT5 Switches to ROC/RICCs. Follow the connections as illustrated in the
figure below.
12
SMART CAT5 SWITCH – 108/116
With the Smart CAT5 116 model, connect up to up to 256 computers through
cascading.
A lower level Switch must have a different hotkey to display its OSD than a higher
level switch. Changing the OSD display hotkey is explained on page 18 below.
