Chapter 2: Installation 19 3. Connect the other end of the CAT 5 cable to a port on the back of your RCM. 4. Attach the keyboard, monitor and mouse connectors of the KCO cable to a user port on your cascade switch. 5. Connect the servers to your cascade switch according to the switch manufacturer's recommendations. 6. Repeat steps 2-5 for all cascade switches to be attached to your system. To operate your RCM with a cascaded multi-user legacy switch: You can cascade a NetBAY 2x8 Console Switch under your RCM or LCM. In a cascaded configuration, the remote and analog workstations can both access servers attached to the cascaded switch. If both the remote and analog workstations want to access different servers on the switch at the same time, you can attach a KCO cable to both user ports to avoid one user blocking the other. Preemptive behavior By default, the console switch operates in preemptive mode. This means that one user can disconnect another user from a server connection without warning. For example, if the analog user is accessing server 1 via KCO cable A and the remote user switches to the same server via KCO cable B, the analog user will be preempted and the remote user will take command of the connection. The analog user's screen will go blank and they will receive no disconnect warning. If you will have users performing sensitive tasks who should not be preempted, you can connect only one KCO cable to the switch. This will ensure that no user can preempt another without administrative privileges at the remote console.

3.
Connect the other end of the CAT 5 cable to a port on the back of your RCM.
4.
Attach the keyboard, monitor and mouse connectors of the KCO cable to a
user port on your cascade switch.
5.
Connect the servers to your cascade switch according to the switch
manufacturer’s recommendations.
6.
Repeat steps 2-5 for all cascade switches to be attached to your system.
To operate your RCM with a cascaded multi-user legacy switch:
You can cascade a NetBAY 2x8 Console Switch under your RCM or LCM.
In a cascaded configuration, the remote and analog workstations can both
access servers attached to the cascaded switch. If both the remote and analog
workstations want to access different servers on the switch at the same time, you
can attach a KCO cable to both user ports to avoid one user blocking the other.
Preemptive behavior
By default, the console switch operates in preemptive mode. This means
that one user can disconnect another user from a server connection without
warning. For example, if the analog user is accessing server 1 via KCO
cable A and the remote user switches to the same server via KCO cable B, the
analog user will be preempted and the remote user will take command of the
connection. The analog user’s screen will go blank and they will receive no
disconnect warning.
If you will have users performing sensitive tasks who should not be
preempted, you can connect only one KCO cable to the switch. This will
ensure that no user can preempt another without administrative privileges at
the remote console.
