Introduction to IEC 61850-3 Rackmount Ethernet Switches
4
Substation and transportation automation networks can be extremely
large and cover expansive territories. Moxa’s rackmount Ethernet
switches satisfy the scalable network requirements with long-haul fiber
solutions from Layer 3 to Layer 2 Ethernet switches.
The PT-7828 Layer 3 Ethernet switch can divide a large network •
into hierarchical sub-nets. Controlling network traffic on separate
subnets can improve the performance of the entire network.
The PT-7710, PT-7728, and IKS-6727 are Layer 2 modular •
managed Ethernet switches that support advanced network
management and control functions, including VLAN, Q0S, IGMP
snooping, LACP, and GMRP to optimize and prioritize network
communications.
Moxa’s rackmount Ethernet switches provide multiple levels of
redundant features:
Media Redundancy
Managed rackmount Ethernet switches come with the world’s fastest
Turbo Ring redundancy (20 ms @ 250 switches), and standard STP
or RSTP redundant protocol. In addition to a single ring redundancy
structure, Turbo Ring also provides multiple ring-coupling functions,
such as “Ring Coupling,” “Dual Homing,” and “Dual Ring.”
Power Input Redundancy
Non-stop operation is the key criterion for mission-critical applications.
The PT-7728/7828 and IKS-6726 support dual, isolated, redundant
power supplies with different power sources (24/48 VDC or 110/220
VAC/VDC input voltage). For example, you can choose 110/200 VAC/
VDC as your main power source, and 48 VDC from a battery as your
back up power source.
Configuration Redundancy
The ABC-01 backup configuration tool can both save and load
configurations automatically when connected to a Moxa managed
Ethernet switch. This novel management tool helps reduce downtime,
and can be used for fast configuration duplication of large-scale
networks.
Ethernet has already penetrated into the industrial environment, and is
now used widely in control rooms, and for connecting controllers and
devices on the shop floor. Industrial Ethernet is not only being used in
a wide range of vertical markets, but is also finding uses in different
facets of each market. For example, IEC 61850-3 industrial Ethernet
networks are applied as the physical medium for power substation
automation, which means that a host of legacy field buses must be
connected to the Ethernet network. The bottom line is that Industrial
Ethernet is now the future trend for automation communication
systems.
Different vertical markets require different solutions, which is why
Moxa developed two distinct rackmount Ethernet switch product lines.
The new PowerTrans PT series of IEC 61850-3 rackmount Ethernet
switches and the IKS industrial rackmount Ethernet switch series were
developed to meet the needs of a variety of applications (see the table
at the right).

The Layer 2 PoE modular managed Ethernet switch IKS-6726-PoE, •
which supports max. 16 PoE (Power-over-Ethernet) ports. The PoE
Ethernet switch provides up to 15.4 watts of power per PoE port,
and allow power to be supplied to connected devices when AC
power is not readily available or cost-prohibitive to provide locally.
The PT-7324 is a smart Layer 2 • Ethernet switch that offers
web-smart functions, such as port-based VLAN and QoS, to make
network management easier.
The IKS-6324 series of unmanaged Layer 2 • Ethernet switches are
reliable plug-and-play Ethernet communication solutions that give
users an easy and economical way to connect with end devices.
