CABLING
It is strongly recommended to use shielded cable for all Canopy infrastructure cabling associated
with Backhauls, Access Points, and Cluster Management Modules. The environment these
modules operate in often has significant or unknown or varying RF energy, and experience has
been that the additional cost of shielded cabling is more than compensated by predictable
operation and reduced debugging and support costs.
The following information describes the wiring standards for installing a Canopy system. All
diagrams use the EIA/TIA 568B color standard.
Currently shipping modules and most modules in the field auto-sense the Ethernet cable type –
either RJ-45 straight-thru cable or RJ-45 crossover cable can be used to connect a network
interface card (NIC), hub, router, or switch to a module.
The following table shows MAC Addresses of Auto-sensing modules:
MAC Address (ESN)
Non-auto-sensing Auto-sensing
5.2 Modules ≤ 0a003e0021c8 ≥ 0a003e0021c9
5.7 Modules ≤ 0a003ef00f79 ≥ 0a003ef00f7a
Earlier modules did not auto-sense. In cases where older, non-auto-sensing modules
are used:
• When connecting a Canopy device directly to a network interface card (NIC)
use a RJ-45 straight-thru cable.
• When connecting a Canopy device directly to a hub, switch, or router use a
RJ-45 crossover cable.
When using the Canopy AC wall adapter the +V is +11.5VDC to +30VDC with a nominal value of
+24 VDC, and the maximum Ethernet cable run with the AC wall adapter is 328 feet (100 meters).
