EISK5-GT/H
Skorpion Gigabit Diagnostic Switch for Protocol Debugging
Installation Guide
The EISK5-GT/H gigabit switching hub is designed as an aid in diagnosing Ethernet
communication issues and debugging software. This device has all of the features
of a normal switch except that — like a repeating hub — it passes messages
received by any port to all other ports. This allows the activity of all ports to be
monitored by a "sniffer" attached to any port — an ability that would otherwise
require the "port mirror" function of a more costly managed switch.
The five ports of the EISK5-GT/H offer features that traditional repeating hubs do
not. Each port supports Auto-MDIX — so either straight-through or crossover
cabling can be used. The collision domain is terminated at each port so there is
no cabling length limit — except that each segment cannot exceed the 100 m
specification for Ethernet.
Store-and-forward operation mitigates against lost
messages. Each port automatically negotiates its data rate to 10 Mbps, 100
Mbps or 1000Mbps.
The EISK5-GT/H has five Auto-MDIX ports for attaching local devices.
In
addition to a power LED, each port has LEDs showing link/activity/rate.
The EISK5-GT/H is powered from a low-voltage source and is provided with a
writeable label for easy identification of the remote device attached to each
cable.
