Management Connection for MIMO and Protection
Configurations
In MIMO and all HSB protection configurations, a special signaling cable must be used to connect
the management ports (MGT/PROT) of the two PTP 820C units.
When Out-of-Band management is used, a splitter must be used to connect the management ports
to local management and to each other.
The MIMO/Protection signaling cables are available pre-assembled from Cambium Networks in
various lengths (see
), but you can also prepare them
in the field.
The following sections explain how to prepare and connect these cables.
Preparing a MIMO/Protection Signaling Cable
To prepare your own MIMO/Protection signaling cables, follow the instructions in
Ethernet Cable and Plug-in Field
You must use the following pinouts:

Connecting a MIMO/Protection Signaling Cable
This option must be used when you plan to manage the system using in-band management.
The MIMO/Protection signaling cable must be connected between the management ports of two
PTP 820C units operating in either MIMO or HSB protection mode. The physical cable connection
