Feature Benefit Feature Benefit
Eliminates the need for Ethernet cross-over cables,
by automatically detecting cable type and configuring
the port appropriately, greatly reducing installation
Dynamic Host Configuration Protocol (DHCP) allows
automatic network settings. A built-in DHCP server
eliminates a separate DHCP server, and for easy
maintenance it can assign IP addresses by switch port
Allows devices with different capabilities (speed:
10/100/1000M, full/half duplex) to automatically
configure ports for optimum communication.
IGMP Snooping allows the switch to listen to
multicast/broadcast traffic, and limits it to required
switch ports. It minimizes network traffic, and is
recommended for Ethernet/IP “Implicit” I/O systems.
Protection
Limits broadcast/multicast traffic to a predetermined
maximum rate (frames/sec) to prevent network
congestion by awry devices.
or Port Trunking
Link Aggregation (IEEE 802.3ad), sometimes called
Port Trunking, is a provision to connect multiple ports
in parallel to increase throughput between switches
and offer higher availability through link redundancy.
Protects Ethernet ports from Electrostatic Discharge
(ESD) of up to 4000 Volts when a switch is handled or
Ethernet cables are connected or disconnected.
IEC61000-4-2 makes certification.
MAC Filtering is a means for enhanced network
security, by limiting network access by unique
Ethernet device ID (MAC address). Specific devices
can be either allowed or denied network access.
Full-duplex operation allows communication in both
directions (send & receive) simultaneously, while half-
duplex limits one device to wait until the other is
Port Mirroring allows eavesdropping on data traveling
in or out one or more switch ports. Used with a PC-
based diagnostics program or protocol analyzer, it is a
valuable for troubleshoot communications problems.
Protection
Ingress Protection Rating classifies the protection
against the intrusion of objects by enclosures. The 1
st
/2
nd
digit is for solid objects/liquids. The higher the
rating the greater the protection is.
Quality of Service (IEEE 802.1p) is a means of
prioritizing network traffic, to ensure time critical
message delivery. For example, messages between
a HMI and PAC can be given priority over e-mail.
Commonly referred to as PoE, and also known as
IEEE 802.3af, Power over Ethernet supplies DC (48V,
15.4W) power to attached devices over the same
Cat5 cable used for a network connection.
Rate Limiting allows traffic to be throttled to a
specified rate (kbps), in an effort to improve network
performance. Limits can be placed on both incoming
and outgoing traffic, on a port-by-port basis.
Ensures uninterrupted communication, even in the
event one external power supply fails.
Rapid Spanning Tree (IEEE 802.1w), replaces
Spanning Tree Protocol (IEEE 802.1D), and provides
redundant switch-to-switch connections, generally
adapting to topology changes in 2 to 6 seconds.
Small Form-factor Pluggable (SFP) modules are
compact electro-optical transceivers that allow a
compatible device to connect to a fiber optic network
The “Modbus” of the IT world, Simple Network
Management Protocol allows remote monitoring and
control of network devices. IT administrators use it to
determine which devices service or maintenance.
