Product Overview
SICOM3028GPT-A is an intelligent modular platform which is an All-in-One solution integrating IEEE1588v2, full gigabit, and both layer 2 & Layer 3 availability specifically designed to operate reliably in electrically harsh and climatically demanding utility substation and industrial environments. SICOM3028GPT-A supports up to 24 gigabit and 4 10gigabit ports or 28 gigabit ports, meets the IEC61850-3 and IEEE1613 standards. SICOM3028GPT-A is a 19-inch 1U rack mountable device and supports one 1U slot and six 0.5U slots which offers the maximum flexibility for easy expansion.
SICOM3028GPT-A supports IEEE1588 PTPv2 with hardware time stamping andsupports the BC, P2P TC, and E2E TC clock modes, it reaches a timing precision of 100 ns. It supports PTP Power Profile and supports many modules for time synchronous like HSR/PRP. SICOM3028GPT-A supports many Layer 2 software features such as port, VLAN, QinQ, multicast, QoS, DRP/DT-RING/MRP ring protocol, STP/RSTP/MSTP and Layer 3 functions such as VRRP, RIP, OSFP, IGMP and PIM. It supports Console, Telnet, Web management and network management software based on SNMP. At present, the product is widely used at the intelligent substation and many other industrial communication systems.
