EISW8-100T
Plug and Play Switching Hub for Automation Systems
Installation Guide
The EISW8-100T 8-port switching hub is designed for networked automation applica-
tions. Like all Ethernet switches from Contemporary Controls, it features non-block-
ing (full wire-speed) operation. It divides an Ethernet network into eight collision
domains—“bridging” data links to create larger network diameters than possible with
repeating hubs. Each port automatically negotiates its data rate to either 10 Mbps or
100 Mbps—controlling data ow with the PAUSE function in full-duplex links or with the
backpressure method in half-duplex links.
The switch provides preamble regeneration with symmetry and amplitude compensation,
retiming signals to eliminate jitter. Digital pre-emphasis compensates for inherent signal
strength roll-off. Link integrity is monitored, verifying that a working adapter or hub is on
the distant end of a segment.
Port assignments are learned by reading Ethernet frames and logging the source
addresses to a table. Throughput is improved by restricting trafc to those ports party
to a data exchange while other data is simultaneously exchanged on other ports.
Store-and-forward operation is implemented, and broadcast, multicast, or unicast
transmissions are received by all ports.
The EISW8-100T has eight Auto-MDIX ports for attaching local devices. Each port has
one LED that glows with an established link and ashes with activity.
The unit features dual power inputs with wide-ranging voltages (12-48V DC or 24V
AC). For power redundancy, two DC supplies can be used. A normally open (NO) fault
relay contact held closed, opens upon a P1 or P2 power failure. This contact is rated
up to 24V DC at 1A. A wide operating temperature range of – 40°C to +75°C make the
EISW8 suitable for outdoor applications.

Power Sourcing Options
Power Considerations
The EISW can be powered from either a single source of AC or DC. Dual source power-
ing is possible with two DC supplies isolated from one another. Recommended size for
solid power conductors is 16–22 AWG; for stranded conductors, use 16–18 AWG. Input
connections are reverse polarity protected. The earthing screw terminal on the switch
must be grounded if there is no other option for grounding the case.
Network Connections
The switch employs Auto-MDIX technology so that either straight-through or crossover
cables can be used to connect to network interface adapters or to another hub.
LED Indicators
The “P1” LED glows green to indicate Power Input 1 (PWR1) has power, and the “P2”
LED glows green to indicate Power Input 2 (PWR2) has power. Each Ethernet port has
a LNK/ACT LED that glows solid green to indicate an established 10 or 100 Mbps link,
and ashes green to indicate that network trafc is occurring over that port.
