If the GPS position information is required to be visible on the web GUI, then the
UGPS power must be enabled on the AP; and it is safe to use both AP power and
external power for a single UGPS unit.
CMM5
The CMM5 (Cluster Management Module) is the latest generation of solutions for the distribution of TDD
Sync signals and “Power-over-Ethernet (PoE)” in the field. The CMM5 is a modular design with individual 4-
port power injectors and an optional controller used for remote management.
Key features of the CMM5 include:
l
Support for Gigabit Ethernet (1000BaseT)
l
Modular and scalable from 4 ports to 32 ports
l
/- 48 V DC input (optional AC/DC power supplies are available from Cambium Networks)
l
Uses Cambium Networks UGPS for a synchronization source
l
Dual resilient power inputs
l
Rack mountable
l
Secure remote management when used with the optional CMM5 Controller Module
l
Support for PMP 450m (cnMedusa™)
l
Future support for integration into (cnMedusa™) for cloud or NOC-based management
It consists of four subsystems, described in the following sections:
l
CMM5 Controller Module
l
CMM5 Injector (29 volt and 56 volt versions)
l
Power supply(s) (240/600 watt)
l
UGPS
