EISK8-100T/F_ Series
Plug and Play Fibre Switching Hub for Automation Systems
Installation Guide
EISK8-100T/F_ switching hubs are designed for automation environments.
Like all Ethernet switches from Contemporary Controls, each switching hub
features non-blocking (full wire-speed) operation.
Two fibre ports communicate at 100 Mbps and each port has one LED for
link status and activity. The series has three models that vary by type of
fibre connector in use. The EISK8-100T/FC and the EISK8-100T/FCS use
the SC type of connector. The EISK8-100T/FT uses the ST type. Only full-
duplex is supported on the fibre ports.
Six copper ports automatically negotiate the data rate to 10 Mbps or 100
Mbps and set flow control with the PAUSE function (full-duplex links) or the
backpressure method (half-duplex links). Each copper port uses the Auto-
MDIX function for attaching local devices and has one LED for
link/activity/rate and one LED for duplex status.
The unit provides preamble regeneration and retimes signals to eliminate
jitter. Digital pre-emphasis compensates for inherent signal strength roll-off.
Link indicates 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. Learned addresses are aged out of the table
after 300 seconds of inactivity. Throughput is optimised by restricting traffic
to only those ports that are party to a data exchange (while other data is
simultaneously exchanged on other ports). Store-and-forward operation is
used. Each port can receive any type of Ethernet message: broadcast,
multicast, or unicast.
Each unit is provided with a writeable label for easy
identification of the remote device attached to each cable.

Power Options
Power Considerations
Voltage in the range of 10–36 VDC or 8–24 VAC must deliver current commensurate
with power consumption. Recommended size for solid power conductors is 16–22 AWG;
for stranded conductors, use 16–18 AWG. Common is directly connected to zero volts and
chassis is isolated from zero volts. Input connections are reverse-polarityprotected.
LED Indicators
The ―PWR‖ LED glows solid green when the switch is properly powered. To aid in
troubleshooting, each copper port has two LEDs. The Port 1 LED labelled ―L‖ glows
solid if a link exists, flashes to show activity and shows data rate by colour: green for 100
Mbps and yellow for 10 Mbps. The LED labelled ―D‖ glows solid green if full-duplex is on
or is unlit when the port is in half-duplex mode —but in half-duplex operation it will flash
if a collision occurs. The LEDs of Ports 2–6 are unlabeled but work the same. The fibre
port (7 and 8) LEDs glow solid green if linked to a working 100BASE-FX port and each
LED flashes when data moves through the port.
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 other
hubs. Cable issues are shown in
the chart to the right.
