EISK5-100T/F_ Series
Plug and Play Fibre Switching Hub for Industrial Automation Systems
Installation Guide
EISK5-100T/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.
One
fibre
port communicates at 100 Mbps and has one LED for link status and activity.
The series has three models that vary by type of fibre connector being used. The
EISK5-100T/FC and the EISK5-100T/FCS use the SC type. The EISK5-100T/FT uses
the ST type. Only full-duplex communication is supported on the fibre port.
Four
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.
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 writeable label for easy identification of the remote device
attached to each cable.
