The EWS4502B is an enterprise-class wireless LAN controller. The unit contains two 1000BASE-T ports and one console port, all in a rack-mountable enclosure. The wireless controller concentrates the management and control of APs from a single or cluster of connected units on the wired network. Up to 200 Fit or Fat APs can be managed from one controller, and up to four controllers can be clustered together. The EWS4502B is ideal for enterprise deployment where a controller cluster can consolidate the RF management of multiple APs, enable network-wide monitoring, and also provide automatic “self-healing” recovery around any failed APs in the network.
