GEL-2870 24x10/100/1000 GE + 4 GE Combo SFP L2 Managed Switch LevelOne

LevelOne GEL-2870 je samostojno Layer 2 SNMP Gigabitno mrežno stikalo s 24 1000Base-T Gigabit mrežnimi porti in 4 Gigabitnimi Ethernet RJ-45 porti s kombinacijo SFP (Small Form Factor Pluggable) vodili. Je polno nastavljivo stikalo s podporo varčevanju el. energije, izpopolnjenim QOS (Quality of Service) in VLAN-om. Vsi porti so lahko v v t.i. agregatnem stanju, kar pomeni večji in hitrejši pretok podatkov če več portov hkrati

GEL-2870 je primeren za napredno omrežje ter z najpomembnejšimi funkcijami managementa, kot so:
STP/RSTP/MSTP protocol for standard bridging
SNMP
RMON ter, napredne varnostne funkcije
