Connecting Cables

Installing Ethernet Cables

Installing a 75-ohm Coaxial Cable

The maximum number of shielded Ethernet cables supported by a ﬂat-door

cabinet is limited. For example, a 300 mm deep ﬂat-door N63B/N63E cabi

net supports a maximum of six shielded Ethernet cables per layer of inter-

face boards.
In contrast, a convex-door cabinet supports more shielded Ethernet cables.

For example, a convex-door A63B/A63E cabinet supports a maximum of 16

shielded Ethernet cables per layer of interface boards.
Connecting a device to an NMS server requires two Ethernet cables: one for

the active main control board and the other for the standby main control

board.
