Channel Colors
Different channel colors on the Selection Menu represent different channel
statuses. Channel colors vary according to these criteria:
The channels are active or inactive. See
What are Active and
Inactive Channels
(on page 30).
The channels are being accessed or not.
Note: The TMCAT17 system does not auto-detect and update the channel
status in real time. To ensure you get the latest channel status, perform
the channel refreshing. See
Refreshing Channel Statuses
(on page 40).
What are Active and Inactive Channels
One of the factors that affect channel colors is the active/inactive status of
a channel, which varies based on the power status of the connected CIM
or MCUTP cable. This section explains the definition of active and inactive
channels.
Active Channels
The TMCAT17 switch recognizes a channel as being active when it
detects that the channel port is connected to a powered CIM or MCUTP
cable. A CIM or MCUTP cable is powered when the computer or device
that it connects supplies power to it via the PS/2 keyboard or USB port.
A CIM or MCUTP cable always receives power in this scenario:
The CIM or MCUTP's PS/2 keyboard or USB connector is plugged
into a computer or device that is turned ON.
The CIM or MCUTP cable may or may not be powered when the computer
is turned OFF, which varies depending on the computer's design.
Tip: You can check the CIM's LED to find whether it is powered. If it is
powered, the LED is flashing. Otherwise, the LED light is off continuously.
