Hirschmann™ unveils HiOS – a new operating system generation for its switches

High network availability for smooth production processes

With HiOS, Belden is launching an entirely new operating system that will set a new benchmark in the automation sector and further extend the range of applications for the Industrial Ethernet switches in its Hirschmann™ product program. It means that intelligent infrastructures can now also be used in time-critical applications that were previously exclusively a "hard-wired" domain, i.e. with point-to-point connections. In transformer substations, for example, to securely connect sensors and controllers to the network via Ethernet.


In addition to numerous management and diagnostic options, HiOS provides precise time synchronization compliant with IEEE 1588v2 plus a variety of redundancy protocols. With zero switchover times, the PRP (Parallel Redundancy Protocol) and HSR (High-Availability Seamless Redundancy) redundancy methods ensure smooth production processes. Comprehensive security mechanisms protect your network against attacks and operating errors, so also contributing to high network availability.

HiOS is currently available in two Layer 2 versions, with a Layer 3 version due to be launched in the course of 2013. Supported by both the Standard and Advanced versions, management protocols include Telnet, SSHv2, HTTP, HTTPS, TFTP, SFTP, and SNMP v1/v2/v3. In addition to PRP und HSR, redundancy protocols also include MRP (Media Redundancy Protocol), Fast MRP, and RSTP (Rapid Spanning Tree Protocol).

The security mechanisms provided by both Layer 2 versions of the operating system comprise MAC-based Port Security, Authentication (IEEE802.1x), Guest/unauthenticated VLAN, Radius Client, Restricted Management Access, Local User Accounts, various Privilege Levels, Management Authentication via Radius, Account Locking, configurable Password Policy and Login Attempts, Audit Trail, CLI/SNMP Logging, and HTTPS-certified Management.

Customers who opt for the Advanced version also obtain "Quality of Service" functions such as DiffServ, VLAN extensions, and security mechanisms such as Access Control List (ACL) and IEEE802.1x Multi Client Authentication.

Both Layer 2 operating system versions can currently be used with switches belonging to the RSP, EES and MSP series. Moving forward, they will be employed in all new managed switches developed for the Hirschmann™ brand.
