Skorpion Diagnostic Switch for Protocol Debugging

Installation Guide

The EISK5-100T/H 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 EISK5-100T/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 that a

network of EISK5-100T/H units has 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 or 100 Mbps — controlling data flow with the PAUSE

function in full-duplex links or with the backpressure method in half-duplex links.

Link integrity is monitored — verifying that a working device is on the far end of a

segment. In addition to the unit's power LED, each port has two LEDs — one

showing link/activity/rate, and one showing duplex status.

The unit operates from low-voltage AC or DC power and is provided with a

writable label for easy identification of the remote device attached to each cable.

Page 3 Power Options Power Considerations Voltage within the specified range must deliver current that is commensurate with power consumption. The recommended size for solid power conductors is 16–22 AWG; for stranded conductors, use 16–18 AWG. Ground is directly connected to zero volts and the chassis is isolated from zero volts. Input connections are reverse-polarity protected.
