EISK8-100T/F_ Series
Plug and Play Fibre Switching Hub for Industrial Automation Systems
Installation Guide
EISK8-100T/F_ switching hubs are designed for Industrial 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 optimized 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.
The switch works from a wide range of low-voltage AC or DC power and features a
power LED.
Each unit is provided with a writable 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-polarity protected.
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.
