Installing Dial Backup and Network Interface Modules
The DIM plugs on to the NIM. The NIM is then installed into the rear panel option module slot. The following
tables list the installation steps. Also, see Figure 16 below and Figure 17 on page 40.
Figure 16. Installing DIMs
For NetVanta modules with outside plant connections, ensure that all cables are
removed from the module before installing or removing it from the NetVanta chassis.
Electronic modules can be damaged by static electrical discharge. Before handling
modules, put on an antistatic discharge wrist strap to prevent damage to electrical
components. Place modules in antistatic packing material when transporting or storing.
When working on modules, always place them on an approved antistatic mat that is
electrically grounded.
Instructions for Installing the DIMs
Step Action
1 Remove power from the unit.
2 If the NIM is already in the NetVanta chassis, remove all cables, release the pins at both edges
of the NIM front panel, and slide the module out of the chassis.
3 Carefully align the P1 connector on the NIM with the J1 connector on the DIM. Using only fingertip
pressure so that neither circuit board bends or flexes, ensure that the connectors are firmly seated.
Secure the DIM to the NIM using the screws and standoff posts supplied. See Figure 16.
4 Slide the NIM with the DIM attached into the NetVanta chassis, continuing with the normal NIM
installation (refer to Instructions for Installing the NIMs on page 40).
