allowing it to be screwed in using standard screws and cage nuts.
Attaching a BNC Rear Connector Strip to the Rear Panel of the NK-3G144
There are two types of BNC rear connector strips that you can attach to the NK-3G144:
• NK-I3G-RC (9807-5104-x 3G input)
• NK-O3G-RC (9807-5103-x 3G output)
Each BNC rear connector strip has two columns of eight connectors each; it is specific to input or output. Each
BNC rear connector strip supports two corresponding cards.
To insert a BNC rear connector strip into the frame
1. Locate the part number on the BNC rear connector strip (on the outer end of the PCB).
2. On the rear panel of the routing switcher, remove the 6 screws from each blanking plate corresponding to the
slots into which you want to insert cards.
