PoE

PoE

The controllers of choice in this deployment are dependent on AP count and PoE requirements. For small offices requiring PoE, the MC-800 or MC-2400 are both capable of providing power for APs. In offices where PoE is not required, the MMC-3200, MMC-3400, and MMC-3600 series controllers provide a range of AP scaling without the additional costs associated with PoE.

Medium Network Deployment

A medium size network is different from a small network in that the network has moved into general production use and controller redundancy is required. At this point, PoE is no longer provided by the Mobility Controller, and a reference architecture for this deployment model would rely on access layer switches for this function. Additionally, two Mobility Controllers exist in the network to provide high availability.
