In general the electrical traffic cables should not be routed in the same route as power cables. The power
connectors on the NPT-1020 are on the left; therefore they should be routed from the left side of the
NPT-1020 pass in the space between the NPT-1020 and the unit installed above it. Then the cable should be
passed through the left cable guide, routed up to the left cable clamp bar and attached to it with cable ties.
It should then be passed upward to the openings in the top cover of the cabinet to the outer world.
In a similar way, cable connected to connector on the right side of the NPT-1020, for instance T3/T4 (clock)
cable should be routed from the right side of the NPT-1020 in the space between the unit and the unit
installed above it. Then the cable should be passed through the right cable guide, routed up to the right
cable clamp bar and attached to it with cable ties.
The route of fibers connected to the NPT-1020 should always pass through the fiber protection tube. This
means that the fiber should be inserted in the tube and come out from its other side from there it should
be routed upward to the opening in the top cover of the cabinet.
