Cascade Rules - CommScope ION E Series Installation Manual

CAP L with a Fiber Interface
•
Connects via its Optical Port 1 to an OPT Card in the CAN/TEN
–
You can connect up to 4 CAP Ls per OPT Card for a total of 16.
–
You can connect up to three CAP L units (or cascaded pairs) to OPT Card Ports 1 - 4. See "Cascade
–
Rules" on page 17.

Cascade Rules

When cascading a Secondary CAP L or an external Ethernet device such as WiFi or an IP camera, you must
observe the following rules, which are also documented in the installation procedures included in this
installation guide.
In a cascade, the CAP L connected directly to the CAN/TEN is the Primary CAP L, and the CAP L that
•
connects to the Primary CAP L is the Secondary CAP L.
The cascaded unit must use the same transport type (Copper or Optical).
•
To cascade two Optical CAP Ls, use a fiber-optic cable.
–
To cascade two Copper CAP Ls, use Cat6A cable. Use 23 AWG Cat6A cable; for cable limitations, see
–
"Cat6A Cable Requirements for CAP Ls with a Copper Interface" on page 40.
The Secondary CAP L must get its power through the DC connector. For CAP Ls with a Copper Interface,
•
power over the Cat6A cable to the cascaded unit is not supported.
You connect CAP Ls with a Copper Interface to a CAT Card in the WCS Subrack. Each CAT Card has four
•
RJ-45 ports (labeled 1 - 4).
You can connect up to three CAP Ls with a Copper Interface (or cascaded pairs) to CAT Card Ports
–
1 - 3.
If installed in CAT Card Port 4, the CAP L with Copper Interface must be locally powered.
–
You connect CAP Ls with a Fiber Interface to an OPT Card in the WCS Subrack. Each OPT Card has four
•
10 Gbps ports (labeled 1 - 4) for fiber connections.
You can connect up to 4 CAP Ls per OPT Card for a total of 16.
–
In a cascade, the CAP L connected to the OPT Card is the Primary CAP L, to which you can connect one
–
Secondary CAP L.
Use of the Auxiliary ports in a cascaded system is limited as described below.
•
For CAP Ls with a Fiber Interface, only use the Auxiliary port on the Primary CAP L.
–
For CAP Ls with a Copper Interface, use the Auxiliary port on the Primary CAP L to connect one of the
–
following:
a locally powered Secondary CAP L

an external Ethernet device such as WiFi or an IP camera.

The total 320 MHz RF bandwidth is shared between the two cascaded units, but can be shared unevenly;
•
that is, with more bandwidth going to either the Primary or Secondary CAP L—either CAP L can transmit
all the 320 MHz RF bandwidth or any subset of it.
After the Primary CAP L powers up, the Secondary CAP L will be discovered and power up on its own; for
•
information on how a CAP L powers up, see "Powering a CAP L" on page 48.
