New standards for network security
and network availability
Hirschmann (a Belden Brand) recently introduced
their new PowerMICE, the third generation of the Modular Industrial Communication Equipment family
for mission-critical applications. This modular switch for DIN rail mounting now offers
comprehensive network protection. The switch incorporates security mechanisms that regulate network
access and protect against attacks. These include port security, DHCP Snooping, Dynamic ARP
Inspection, IP Source Guard, ingress / egress ACL, sFlow, Storm Control, automatic
Denial-of-Service prevention and port access control via 802.1x including multi-client
authentication, Radius VLAN/policy assignment and guest/unauthenticated VLAN. Hardware redundancy
methods such as PRP (Parallel Redundancy Protocol) and HSR (High Availability Seamless Redundancy)
also ensure uninterrupted data communication. As a result, this IPv6-ready switch allows
applications to be implemented where both an extremely high level of network security and network
availability are required. It can also be seamlessly integrated into PROFINET and EtherNet/IP
environments. The integrated PoE Plus function allows for cost-effective power supply for terminal
The new PowerMICE is available in three basic
versions for 12, 20 or 28 ports and comprises a switch unit with integrated backplane and a 4-port
Gigabit Ethernet media module. Depending on the version, the switch can be individually fitted with
up to six additional 4-port Fast Ethernet media modules for twisted pair cables, different optical
fiber types or I/O functionality.
Media modules can be assembled quickly without
tools using a click-in mechanism. Modules can be removed just by using a screwdriver to lift a tab
attached to the switch. For applications that require a high level of vibration resistance, modules
can also be fastened using screws.
The switch meets all relevant industry standards
and also offers high shock and vibration resistance. The temperature range is 0 °C to +60 °C.
Optional versions are also available for ambient temperatures from -40 °C to +70 °C. Their circuit
boards can be specially coated (conformal coating) on request to protect against
Power can be supplied via 18-60 VDC or 47-57 or
53-57 VDC. In addition, devices can be supplied with power via PoE Plus via the data cable.
Depending on the power supply configuration, up to 120 watt can be supplied via the backplane of
The switch status can be monitored locally.
Detailed information can be displayed via a standard web browser. The integrated SNMP interface
offers an additional centralized management function that makes it possible to use network
management software such as Industrial HiVision. Configuration and diagnostics can be carried out
with HiDiscovery, IHV or via a web interface.
With the new PowerMICE, Hirschmann has again
demonstrated its technology leadership in the area of Industrial Ethernet. Product Manager Pascal
Unterdorfer comments: "This switch offers unique security features and innovative hardware
redundancy methods, in short: maximum network availability. It means that maximum productivity of
the connected machines and equipment is ensured at all times."
