NOTE:
Auto-negotiation of data throughput and Ethernet operating speed depend on the connected device being
set to auto-negotiate as well.
Each of these cluster management products is supported by its own dedicated user guide that
which provides instructions for mounting and cabling the unit and verifying its connectivity to the
network.
Antennas for 900-MHz Connectorized Modules
Like the 2.4-, 5.2-, 5.4-, and 5.7-GHz module, the 900-MHz connectorized module has
• the same housing.
• a covered Ethernet port.
• a utility port for an alignment headset, sync cable to CMM2, or override plug.
The 900-MHz AP or SM is available either
• as a connectorized unit with a 16-inch (approximately 40-cm) cable with a male N-type
connector for connection to the antenna.
• with an integrated horizontally-polarized antenna in a different form factor.
Cambium has certified three connectorized flat panel antenna options. Cambium resells one of
these. The three flat panel options are as follows:
• 10 dBi Maxrad Model # Z1681 (MP9027XFPT or Cambium AN900A),
26 dBm (390 mW).
