High network availability for
smooth production processes
IAC recently announced the introduction in the EMEA
region of an entirely new operating system for the managed switches in its Hirschmann product
program – HiOS.
With the new HiOS operating system, specially developed to meet requirements
in the automation sector, Hirschmann (a Belden Brand) has further extended the range of
applications for the Industrial Ethernet switches: "The performance of this operating system
will set a new benchmark for the automation sector", says Product Manager Jürgen Schmid. "It
permits the use of intelligent infrastructures in time-critical applications, previously
exclusively a 'hard-wired' domain, i.e. with point-to-point connections. In a transformer
substation scenario, for example, this allows sensors and controllers to be securely
connected to the network via Ethernet".
In addition to numerous management and diagnostic options, both the Standard
and Advanced versions provide 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 networks against attacks and
operating errors, so also contributing to high network availability. On top of this, the
Advanced version provides additional "Quality of Service" functions such as DiffServ, VLAN
extensions, and security mechanisms such as Access Control List (ACL) and IEEE802.1x Multi
Both 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.
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). Security mechanisms 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.
