Dual Stage Routing Systems
System Configuration
If the enclosures were ordered as a DSR System, the configuration file stored in the system is ready for
dual stage routing.
If you are creating a DSR System with existing equipment, the hardware must support dual stage routing
(to verify, contact technical support; see page 6) and the configuration file must be reconfigured and
loaded before the DSR System will work. If the configuration file needs to be reconfigured for DSR
System routing, we strongly recommend contacting technical support to request a modified file.
Caution:
Use X
N
Connect only if you need to modify or customize your system’s configuration
from the original specifications. Be sure to make duplicate copies of the file before and after it is
modified and provide a copy of the modified file to technical support for future support.
A DSR System is created by combining each enclosure’s existing virtual matrices (VMs) in the
configuration (.xcl) file using X
N
Connect. The VMs that make up a DSR System are called constituent
VMs. The individual constituent VMs are not accessible for control purposes.
Tip:
If you want to customize the channel names for a DSR System in the configuration file, do
so after the system has been created.
Creating a DSR Virtual Matrix
The simplest way to create a DSR System configuration is to use the Discover Hardware option in
X
N
Connect, create a constituent VM for each router, and then create the DSR VM using the constituent
VMs.
Tip:
If additional VMs will be added to the system in the future, we suggest using relatively high
numbers (e.g., 30, 31, and 32) for the constituent VMs. This is because constituent VM
numbers are reserved (i.e., they cannot be reused for additional VMs within the system) and it
is usually easier to keep track of switching on lower numbered VMs.
To create the constituent VMs for DSR Systems:
1.
From the File menu, select Discover Hardware Only.
2.
Create the final-stage VM using all of the inputs and outputs used in the final-stage router (see
“Creating a New Virtual Matrix” in the Help file).
3.
Create a pre-stage VM using all of the pre-stage router’s inputs and a number of outputs that is
equal to the number of outputs used in the final-stage router.
4.
Optional – Repeat Step 3 for each additional pre-stage VM.
