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.
