Inactive Channels
The TMCAT17 switch recognizes a channel as being inactive when it does
not detect that the channel port is connected to a powered CIM or MCUTP
cable, which involves these scenarios:
No CIM or MCUTP cable is connected to the channel port.
A CIM or MCUTP cable is connected to the channel port, but it is
unpowered as its PS/2 keyboard or USB connector is not plugged into
any computer or device.
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.
Channel Colors and Statuses
This table indicates channel statuses and corresponding channel colors.
Color Channel status
Black This is an inactive channel.
Green This is an active channel that you can access.
In the Private mode, active channels are green as long as
the other user is NOT accessing them.
In the PC Share mode, every active channel is green no
matter the other user is accessing them or not.
Red This is a channel, either active or inactive, which you cannot
access.
In the Private mode, a channel is red when the other user is
accessing it. If the channel is connected to a second-tier
device, all channels of that second-tier device are red, too.
In the PC Share mode, a channel is red only when it is
connected to a second-tier device that is being accessed
by the other user. In addition, all channels of the accessed
second-tier device are red.
