Management Connection for 4x4 MIMO and 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 units and
provide management access to each unit.
The MIMO/Protection signaling cables are available pre-assembled from Cambium Networks 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.

Note
Before tightening the gland, make sure the gland is even with the cover. Tighten the
gland gently and make sure there is no resistance. If there is resistance, stop
immediately and verify that the gland is not being inserted at an angle. Tightening the
gland at an angle can ruin the thread on the gland and prevent proper sealing of the
interface.
