The ZJIES3000D-P-8PGT4GB is an industrial managed Gigabit PoE Ethernet switch with 8 x 10/100/1000Base-T ports supporting IEEE802.3af/at PoE+ (up to 30W per port) and 4 x 1000Base-X SFP fiber slots, letting a single unit power and network cameras, IP phones, and wireless APs while uplinking toward multiple fiber directions. Full management is supported, including QoS, VLAN, IGMP Snooping/GMRP, Port Trunking, and SNMP v1/v2/v3. Multiple ring-redundancy protocols (RSTP/STP/MSTP/ERPS/ZJRing) improve network reliability and interoperability, and the wide-temperature, EMC-hardened design meets demanding industrial field conditions for building fully-gigabit PoE ring networks.
