Installing the Cisco NCS 4216
A Y-cable is required to connect to a primary and backup RSP in order to ensure that the router continues
Note
to transmit timing signals in the event of a network failure. For a mini-coax connection, this Y-cable can
be part number CAB-BNC-7INY (7 inch BNC Y-cable). For an Ethernet connection, this Y-cable can be
a RJ45 Cat5 1-to-2 splitter (3 female port RJ45 connector).
Note
When installing the cabling to the RSPs, we recommend that you leave a service loop of extra cabling
sufficient to allow for fan tray removal.
