NETWORKING INFORMATION
The 30/60 Mbps Backhaul operates as a transparent Ethernet bridge. Each unit requires an IP
address. This IP address is for management purposes only and it plays no part in the operation
of the system. IP addresses are assigned during initial configuration as described in Section 7.2
"Installation Procedure".

LIGHTNING PROTECTION
The amount of lightning protection is dependent on regulatory requirements and the end user
requirements. The standard 30/60 Mbps Backhaul ODU is fitted with features to minimize the
risk of damage due to nearby lightning strikes. These standard features may require some
additional equipment to be configured as part of the system installation to be fully effective.
Motorola recommends the use of shielded cable and surge arrestor to protect connected
equipment from nearby strikes.
Note: The 30/60 Mbps Backhaul is not designed to survive direct lightning strikes. For this
reason the unit should not be installed as the highest point in a localized area, unless specific
precautions are taken. See Section 11 "Lightning Protection".

ELECTRICAL REQUIREMENTS
The 30/60 Mbps Backhaul is supplied with a variable input voltage (90-264V, 47-63Hz AC)
inline power supply unit which is incorporated into the 30/60 Mbps Power Indoor Unit (30/60
Mbps PIDU). The 30/60 Mbps Backhaul requires one mains AC power outlet at each end of the
link.
Alternately, Canopy 30/60 Mbps Backhaul may be powered by a DC supply (45-55V) through
the terminals provided under the left hand cover on the 30/60 Mbps PIDU.
