The AT-8000GS Gigabit Ethernet Switch series includes three device models, which consist of the following hardware configurations:
AT-8000GS/24 Gigabit Ethernet Switch with 24 10/100/1000 Base-T ports with 4 1000Base-X SFP combo ports and 2 HDMI interface stacking ports.
AT-8000GS/24POE Gigabit Ethernet Switch with 24 10/100/1000 Base-T ports ports with modular configuration 4 x 1000Base-X SFP Combo ports and 2 HDMI interface stacking ports and support for 802.3af Power over Ethernet on the RJ-45 ports. The total POE power available is 140W which allows for a maximum of nine class 3 devices (15.4W per device) or a dynamic distribution of power across any or all 24 ports based on user-assigned priorities.
AT-8000GS/24POE Gigabit Ethernet Switch with 48 10/100/1000 Base-T ports with modular configuration 4 x combo 1000Base-X SFP Combo ports and 2 HDMI interface stacking ports.
All the platforms can operate as standalone systems, or can be stacked together in the same system. A stack of six units maximum is supported.
In each stack, at any given point of time, there is a single Stack unit that is the stack’s “Master”; all other units are “Slaves”. One of the slaves can act as a backup master, so that in the event of failure of the master unit, the backup takes over. The Stack architecture provides for dynamic learning of the topology, and dynamic detection at stack start-up.
Device configuration is performed through an Embedded Web Server (EWS) or through a Command Line interface (CLI). The device management is performed through an RS-232 interface.
