case the user may be required to take adequate measures.

Achtung !

Dieses ist ein Gerät der Funkstörgrenzwertklasse A. In Wohnbereichen können bei Betrieb dieses Gerätes
Rundfunkstörungen auftreten, in weichen Fällen der Benutzer für entsprechende Gegenmaßnahmen
werantwortlich ist.

Attention !

Ceci est un produit de Classe A. Dans un environment domestique, ce produit risque de créer des
interférences radioélectriques, il appartiendra alors à l’utilsateur de prende les measures spécifiques
appropriées

VCCI Class 1 Compliance

This equipment is in the 1st Class category (information equipment to be used in commercial and/or
industrial areas) and conforms to the standards set by the Voluntary Control Council For Interference by
Data Processing Equipment and Electronic Office Machines aimed at preventing radio interference in
commercial and/or industrial areas. When used in a residential area or in an adjacent area thereto,
interference may be caused to radio and TV receivers, etc. Read the instructions for correct handling.

E-FL-HB-0x00 IN THE NETWORK

Install one E-FL-HB-0x00
hub and use fiber cable to
set up a workgroup by
connecting the hub to
terminal devices.

Install an optional backbone
uplink adaptor at the back of
the hub and use 10BASE-2,
10BASE-5, or fiber cable to
connect the workgroup to a
network backbone.

Cascade two repeater hubs by
connecting fiber cable from a connector
at the front of the first hub to a
connector at the front of the second
hub.

E-FL-HB-0x00 in Half-Duplex Network

The 5-4-3 Rule applies separately to each collision domain. NOTE: A
collision domain is any Carrier Sense Multiple Access with Collision Detection
(CSMA/CD) network in which a collision will occur if two attached stations
transmit at the same time. A segment is the cable connection between two
network interfaces.

USING THE 5-4-3 RULE:

The 5-4-3 Rule allows no more than five segments in any 10-Mb/sec
Ethernet collision domain, no more than four repeaters (hubs) and no
more than three populated segments (10Base-2 or 10BASE-5 coaxial­cable installations).

To determine the size of the collision domain by assigning segment
numbers to cable connections, determine the two network devices in a
transmission path that are separated by the greatest number of segments.
Define a segment path between the network devices by labeling the
cable connection to the first device “segment 1” and numbering each
segment in the path to the last network device, up to “segment n” (n =
total number of segments ≤ 5). Verify that no segment path in the entire
collision domain contains more than n ≤ 5 segments.
