Management Connection for 1+1/2+2 HSB Configurations

In 4x4 MIMO and all HSB protection configurations, two Y-splitter cables and a special signaling cable
must be used to connect the management ports (MGT/PROT) of the two PTP 820C HP units and provide
management access to each unit.
The MIMO/Protection signaling cables are available pre-assembled from Cambium in various lengths, but
users can also prepare them in the field.
The following sections explain how to prepare and connect these cables.

Preparing a MIMO/Protection Signaling Cable

The MIMO/Protection signaling cables require the following pinouts.

Figure 21 MIMO/Protection Signaling Cable Pinouts

Note
Other than the pinout connection described above, the cable should be prepared according
to the cable preparation procedure described in
Connecting the MIMO/Protection Splitters and Protection
Signaling Cable
Each splitter has three ports:
• System plug ("Sys") – The system plug should be connected to the PTP 820C HP's management port.
