Recommended Network Setup for 3190 Type Shelves
The configuration shown in Figure 3 is the recommended setup for 3190 type mechanics shelves. Position the HRM-238 shelf below the 3190 type shelves. This limits the distance for the wire leads between the connectors for the management units and the line units they manage. Figure 3 shows the HRM-238 shelf from the rear view with the A-side connectors on the right and the B-side connectors on the left. The leads from the HRM-238 shelf connector attach to the Network Management Agent (NMA) pins on the rear of the 3190-type mechanics shelves for each line unit managed. The NMA pin on 3190 type chassis is pin 7.

Recommended Network Setup for DDM+ Type Shelves
The configuration shown in Figure 4 is the recommended setup for DDM+ type mechanics shelves. Position the HRM-238 shelf below the DDM+ type shelves. This limits the distance for the wire leads between the connectors for the management units and the line units they manage. Figure 4 shows the HRM-238 shelf from the rear view with the A-side connectors on the right and the B-side connectors on the left. The leads from the HRM-238 shelf connector attach to the Network Management Agent (NMA) pins on the rear of the DDM+ type mechanics shelves for each line unit managed. The NMA pin on DDM+ type chassis is pin 104.
