Chapter 5: Installing Power and Connectivity 35
If Your System Includes a Producers Desk
The width of a system (number of chassis) determines Ethernet switch, PSU, and Cable Set installation requirements. When as-
sembling a system that includes a Producers Desk, the following factors affect whether or not the two chassis that comprise the
Producers Desk are included in the total frame width, and whether or not a PSU is required in any Producers Desk chassis:
• The location (left to right) of the Producers Desk in the frame
• The presence (or absence) of Fader Modules or other modules in either or both of the Producers Desk chassis
Examples
Frame Width Ignores Producers Desk
If you want the Producers Desk at the far left or right end of the frame, and will not be installing any modules in any of its chassis,
ignore the Producers Desk when determining switch and PSU placement. For example, Figure 4 shows an empty Producers Desk
installed at the far right. In this configuration, the Ethernet switch goes in the middle channel chassis (E in Figure 4).
Frame Width Includes Producers Desk
If you want the Producers Desk anywhere other than the far left or right end, and you will not be installing any modules in the Pro-
ducers Desk, then include the Producers Desk when determining switch placement. For example, Figure 5 shows a Producers Desk
between channel chassis and the master section chassis. In this configuration, the Ethernet switch goes in the left chassis of the Pro-
ducers Desk (E in Figure 5).
Regardless of where the Producers Desk is installed, if you add Fader Modules (or any other modules) to either or both of its chassis
then include the Producers Desk when determining switch and PSU placement. For example, Figure 6 shows a Producers Desk
with Fader Modules at the far right. In this configuration, the Ethernet switch goes in the master section chassis (E in Figure 6), and
PSUs in both chassis of the Producers Desk (P in Figure 6).
