INS-8528M is a managed industrial switch with eight 10/100Base-Tx ports and 2 Gigabit SFP slots. It is built with industrial-grade components, enclosed in IP30 aluminum casing, and designed to withstand vibration, shock, free fall, and temperatures ranging from -40°C to 75°C. It is DNV (Det Norske Veritas) certified and perfectly suited for harsh industrial environments and maritime and offshore applications.


Robust Electrical and Electromagnetic Safeguard
Engineered to withstand EMI (electromagnetic interference), ESD (Electrostatic discharge), power surge, over voltage, over current, and reverse polarity. networks into smaller parts and separate broadcast domains.
Port-based and IEEE 802.1Q VLAN
GARP (Generic Attribute Registration Protocol) and GVRP (Generic VLAN Registration Protocol) for segmentation of large networks into smaller parts and separate broadcast domains.
Redundant Power System
Powered simultaneously with two different power sources, e.g. SDR-480P-48 power supply and IRA-120/IRA-160 DIN-rail mountable AC to DC power adapter, with power failure alarm.
Efficient Traffic Prioritization
Effective QoS (Quality of Service) mechanisms for priority assignment, transmission of dedicated traffics to specific applications, and allocation of appropriate bandwidth to mission-critical communications.
Redundant Ring for Fast Network Recovery
Xpress Ring for detection and recovery of link failure in milliseconds.
