Installation Guide
The EIBA5-100T and EIBA5-100T/R switching hubs are designed for the Building
Automation environment. The EIBA5-100T is flanged for panel-mounting. The EIBA5-
100T/R has a clip for mounting to 35 mm DIN-rail. Either switch divides an Ethernet
network into five collision domains — ―bridging‖ data links to create larger network
diameters than possible with repeating hubs. 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.
Each device provides preamble regeneration with symmetry and amplitude
compensation — retiming signals to eliminate jitter. Digital pre-emphasis compensates
for inherent signal strength roll-off. Link integrity is monitored, verifying 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. Throughput is improved by restricting traffic to those ports party
to a data exchange — while other data is simultaneously exchanged on other ports.
Store-and-forward operation is implemented and broadcast, multicast, or unicast
transmissions are received by all ports.
Each switch has five Auto MDI/MDIX ports for attaching local devices. In addition to
one power LED, each port has an LED showing link/activity/rate.
Each unit operates from a wide range of low-voltage AC or DC power.
Each unit is provided with a writable label and a corresponding
set of cable tags for ease of cable identification.
