5.1.1.7 Coax Connections for HEU-OIU 4X4 Installation Configurations
Figure 5-10 and Figure 5-11 illustrate the optimal installation configurations when installing four HEU and four OIU chassis in a
rack so that all HEU units can be connected to all OIU units. The optimal configuration takes into consideration the minimum
and maximum ERFC cable lengths (provided with OIX modules) in either a single 19-inch rack (shared rack equipment
scenario) or two separate racks (dedicated rack per operator).

Figure 5-10 illustrates how each HEU is connected to each OIU in a dedicated equipment (single rack) scenario. In Figure 5-11
the port numbers (1-4) indicated on each HEU correspond to the OIUs in the rack and vice versa for the OIU port numbers. For
example, Port 3 in HEU #1 indicates the connection to OIU #3, whereas Port 1 in OIU #3 indicates the connection to HEU #1.
