♦Full hub stack and network management provided via an SNMP man- agement agent (DFE-2616i, DFE-2616ix, DFE-2624i, DFE-2624ix).
♦An optional slide-in switch module allows bridging between 10Mbps and 100Mbps segments. Only one switch module is needed per stack, but managed hub stacks can make use of additional switch modules for redundancy.
♦LED indicators for power, collisions, link, network activity, parti- tioning status, disable, operating speed (10 or 100Mbps) and network utilization.
♦Digital hub ID number front panel display.
♦Auto-partition protection.
♦Data collision detection and handling.
♦Preamble regeneration, signal retiming.
♦Two proprietary daisy-chain ports for cascading up to five hubs to form one logical hub; management provided via a master hub.
♦Standby backup master capability when two master model hubs are present within a single stack.
♦Uplink port allows easy linking of two Fast Ethernet or four Ethernet hub stacks to further expand your network.
♦Standard-size (19”, 1.25U height), rack mountable
♦Built-in, removable power supply, replaceable without opening the hub. Power supply is easily removed and replaced. Automatic volt- age selection (100V to 240V, 50 or 60Hz) without fuses to change or a voltage switch to set.
♦Optional slide-in modules: Switch, 100BASE-TX, and 100BASE-FX
