removed from the module before installing or removing it from the NetVanta chassis.
• Always remove power from the unit prior to removing or installing a module.
• Improper installation may result in damage to the modules.
Instructions for Installing the DIMs
Step Action
1Remove power from the unit.
2If 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.
3Carefully 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 36.
4Slide the NIM with the DIM attached into the NetVanta chassis, continuing with the normal NIM installation
(refer to Instructions for Installing the NIMs below).
