Installing CAP Ms
INSTALLING CAP MS
The following sections guide you through the installation of a CAP M. Pay attention to all cautions and follow
the steps in the order presented.
CAP M Installation and Cascade Rules
When cascading a Secondary CAP M or an external Ethernet device such as WiFi or an IP camera, you must
observe the following rules.
• In a cascade, the CAP M connected directly to the Classic CAN or TEN is the Primary CAP M, and the CAP M
that connects to the Primary CAP M is the Secondary CAP M.
• You connect CAP Ms to an OPT Card in the Classic CAN or TEN.
– Each OPT Card has four 10 Gbps ports (labeled 1 - 4) for fiber connections.
– You can connect up to 4 CAP Ms per OPT Card for a total of 16 Primary CAP Ms, per Classic CAN or
TEN.
– You can connect one Secondary CAP M to each Primary CAP M for a total of eight CAP Ms per OPT
Card, which 32 total CAP Ms per Classic CAN or TEN.
• 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 M—either CAP M can
transmit all the 320 MHz RF bandwidth or any subset of it.
• The Primary and Secondary CAP Ms power up as soon as power is applied to them. In a cascade, the GUI
discovers and readies the Primary CAP M for RF first, and then the Secondary CAP M will be discovered
and readied for RF. For information on the Power LED behavior, see "Power the CAP M” on page 66.
• SMF or MMF connects the CAP M via its Optical Port 1 to the OPT Card.
• When cascading a Secondary CAP M or an external Ethernet device such as WiFi or an IP camera, you
must observe the following rules.
– To cascade two CAP Ms, use a fiber-optic cable.
– SMF or MMF connects the Secondary CAP M via its Optical Port 1 to the Primary CAP M via its Optical
Port 2.
– You can connect the following to the Primary CAP M
 a Secondary CAP M
 an Ethernet device
 both a Secondary CAP M and an Ethernet device.
• To add a Secondary AP, you must add an Optical OCTIS kit to the Primary CAP M, see "OCTIS™ Kits” on
page 9.
• To add an Ethernet device, you must add an RJ45 OCTIS kit to the Primary CAP M, see "OCTIS™ Kits” on
page 9.
CAP M APs require the use of RFD Card PN 7633229-01 or 7633229-02 or higher.
