5.1.9 Cluster Management Module 2 (Part 1008CK)
The Cluster Management Module 2 (CMM2) provides power, GPS timing, and networking
connections for an AP cluster. If the CMM2 is also connected to a BH, then the CMM2 is
the central point of connectivity for the entire site. The CMM2 can connect as many as
eight collocated modules—APs, BHMs, BHSs—and an Ethernet feed.
The CMM2 requires two cables for each connected module:
◦ One provides Ethernet communications and power. This cable terminates in an
RJ-45 connector.
◦ The other provides synchronization (sync), GPS status, and time and date in a
serial interface. This cable terminates in an RJ-11 connector.
A CMM2 is pictured in Figure 10. A CMM2 as part of a mounted Canopy system is
pictured in Figure 11.

5.1.10 Cluster Management Module micro (Part 1070CK)
The Cluster Management Module micro (CMMmicro) provides power, GPS timing, and
networking connections for an AP cluster. If the CMMmicro is connected to both an AP
cluster and a BH, then the CMMmicro is the central point of connectivity for the entire
site. Unlike the CMM2, the CMMmicro is configurable through a web interface.
The CMMmicro contains an 8-port managed switch that supports Power over Ethernet
(PoE) on each port and connects as many as eight collocated modules—APs, BHMs,
BHSs—and an Ethernet feed. The CMMmicro auto-negotiates speed to match inputs that
are either 100Base-TX or 10Base-T, and either full duplex or half duplex. Alternatively,
these parameters are settable.
A CMMmicro requires only one cable, terminating in an RJ-45 connector, for each
connected module to distribute
◦ Ethernet signaling.
◦ power to as many as 8 collocated modules—APs, BHMs, or BHSs. Through a
browser interface to the managed switch, ports can be powered or not.
