Backhaul Slave (BHS)
The BHS is a self-contained unit that houses both radio and networking electronics. The BHS is available in a
connectorized model and also in an integrated antenna configuration, but may also be used with a passive reflector
dish or CLIP (Cassegrain Lens for Improved Performance, 5 GHz only).

3.5 GHz and 3.6 GHz PTP 450 BHSs appear a bit different from the existing 5 GHz PTP 450 BHSs.
Mounting brackets
For mounting PTP 450 BHSs, Cambium Networks offers the SMB1A mounting bracket.
Network connection
The network connection to a PTP 450 Series BHS is made via a 10 BaseT or 100 BaseT Ethernet connection.
Power is provided to the BHS over the Ethernet connection using a patented non-standard powering technique.
BHS power supply
The BHS power supply generates the BHS supply voltage (29 VDC) from the external DC source and injects the
supply voltage into the BHS.
The power supply is connected to the BHS and network equipment using Cat5e cable with RJ45 connectors.
See Cabling and lightning protection on page 1-13 .
