Industrial Ethernet
• Modular design supports mix and match-
ing of connection types and speeds
• Management option for easy troubleshoot-
ing and configuration
• High availability option with dual links
• Redundant power inputs
• Rugged DIN-rail mounted enclosure
Ethernet is moving to the factory floor as the
major network interface in many industrial and
automation applications because it delivers higher
speeds, better reliability and lower cost of owner-
ship. Applications in this environment present special
requirements that traditional enterprise Ethernet
does not address. Metrobility's Industrial Ethernet
DIN-rail chassis offers a modular, managed alterna-
tive to existing special-purpose technologies.
The RD20-24 is a two-slot, DIN rail chassis
which will accommodate any of Metrobility's wide
range of line cards for Ethernet, Fast Ethernet, 10/
100 rate adaption, "redundant" line protection and
restoration (LPR), and BWDM (single strand bi-direc-
tional wavelength division multiplexer). Because it is
modular, users can choose the line card which best
fits their needs:
•
Ethernet, Fast Ethernet or Gigabit Ethernet interface
line cards support both legacy and future applica-
tions
•
Fast Ethernet or Gigabit Ethernet access line cards for
extended management capabilities
•
10/100 rate adaption enables legacy 10Mbps devices
to communicate with 100Mbps devices, protecting
investments.
•
Patented+ LPR line cards offer unique Network-on-
Demand capabilities that allow for dynamic failover
(6.72µsec over 100Mbps, one Ethernet packet) for
loss of link or loss of traffic, or the ability to manually
switch links for backup or maintenance operations.
•
BWDM multiplexes receive and transmit signals over
two separate wavelengths on a single strand of fiber,
doubling the installed fiber capacity. This is an eco-
nomical alternative to installing additional fiber to
accommodate the growing network.
•
A four-port switch card provides four 10/100 RJ-45
interfaces to enable up to three devices to share a
single fiber connection.
Line cards are available with a variety of trou-
bleshooting options including remote loopbacks, Link
Loss Return, Link Loss Carry Forward, Auto-Recovery
and Far End Fault. These features are model depen-
dent, and are configurable manually through a
DIP switch on each device, or through Metrobility's
NetBeacon® Element Manager or WebBeacon™
software.
Management Options
Metrobility's NetBeacon management software
offers an SNMP-based element management system
that supports functional, operational and environ-
mental monitoring and management of Metrobility's
mixed-media physical layer network elements from a
central management station.
Using NetBeacon, network managers can access
each device remotely, adjust operating parameters
quickly across the network. All platform configura-
tion updates, maintenance, and diagnostics can be
performed remotely.
Extensive real-time information on SNMP MIB-II
and Metrobility-specific MIB statistics — plus alarm
thresholds and notification procedures — enable early
problem identification, fast fault isolation and proac-
tive management to prevent problems before they
affect operations.
WebBeacon, a web kernel embedded in the
management card operating system, enables web-
based management via a browser.
