The MDS-G4028-4XGS-T is the wide-temperature version of the modular 28-port 10G switch, operating from -40 to 75°C. With 24x Gigabit interfaces and 4x 10G SFP+ uplinks, it combines port density with backbone performance.
Expansion slots support LM-7000H modules for copper, fibre, or PoE+. Dual hot-swappable LV or HV power modules provide redundant supply flexibility.
IEC 61850-3/IEEE 1613 certification ensures immunity to EMI, surges, and vibration. PRP/HSR redundancy, Turbo Ring/Chain, RSTP, and MSTP guarantee network resilience. IEEE 1588 PTP, with IEC 61850-9-3 and IEEE C37.238 profiles, supports time synchronisation. MMS/IEC 61850-90-4 and HTML5 management streamline SCADA integration.
The MDS-G4028-4XGS-T is a rugged, high-availability option for substations and industrial applications that require scalable 10G-ready Ethernet switching in extreme conditions.
