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:
- Support for Gigabit Ethernet (1000BaseT)
- Modular and scalable from 4 ports to 32 ports
- Direct +/- 48VDC input (optional AC/DC power supplies are available from Cambium Networks)
- High-power output support for 5 GHz PMP 450m (cnMedusa™)
- Uses Cambium Networks cnPulse or uGPS for a synchronization source
- Dual resilent power inputs
- Rack mountable
- Secure remote management when used with the optional CMM5 Controller Module
- Future support for integration into (cnMedusa™) for cloud or NOC-based management

CMM5 Controller Module
The major features of the CMM5 Controller Module are:
- Auto-detect/control up to 8 Power Injectors
- Monitor SYNC/Power/GPS status
- Manage (up/down ports)
- Web (HTTPS) and SNMPv2/v3 management
- 1U/ half-width rack-mount
CMM5 Injector Module
The CMM5 Injector Module has the following features:
- Stand-alone mode or used with controller for mgmt.
- +/- 48VDC input with green/amber LED’s for status
- Injects SYNC pulse from cnPulse or uGPS
- 2U / half-width rack-mount
Note that there are two different versions of the injector module (56V and 29V). You must select the correct injector for the types of radios that you will be powering. In both cases the injectors use the same 48-56V input power supplies or can be powered with +/- 48VDC. The output power is different and the type of SYNC signal used is different between the two types of injectors.
The 29V injector uses a physical layer sync signal that interrupts one of the pins every second to pass the 1PPS information to the radio.
The 56V injector uses a different physical layer sync signal that induces the 1PPS signal onto the drop cable. This new physical layer sync signal is compatible with 1000BaseT.
Systems can have 29V and 56V injectors deployed alongside each other.
