The ZJIES3000D-P-8PGT2GB-DCH is an industrial managed Gigabit PoE Ethernet switch with 8 × 10/100/1000Base-T ports (IEEE802.3af/at PoE+, up to 30 W per port) plus 2 × 1000Base-X SFP fiber slots for uplink. It combines power and data over a single cable for cameras, IP phones and wireless APs, with full management (QoS, VLAN, IGMP Snooping/GMRP, Port Trunking, SNMP v1/v2/v3) and multiple ring-redundancy protocols (RSTP/STP/MSTP/ERPS/ZJRing, self-healing under 50 ms). Its wide-temperature (-40 ~ +75°C), EMC-hardened DIN-rail design suits demanding industrial sites building fully-gigabit, fiber-uplinked, self-healing ring networks.
