Overview
The EMG 8500 is a compact edge management gateway for branch offices, remote sites and retail stores where space is limited. Two front slots take field-replaceable modules with four RS-232, four USB or four Ethernet device ports, and two rear slots take LTE, Wi-Fi or dial-up modem modules for out-of-band access. Automatic failover and failback to 4G LTE keeps engineers connected to network equipment when the primary link is congested or down. It is managed centrally through Percepxion for Networking.
