Ethernet™ Repeater Hub
Male AUI Connector/PC Connection
The male AUI card (E-AUI-
DC-SIC) provides a male
AUI connector for
connection, through an AUI
drop cable, to a 10Base5
port on a powered PC.
Fiber Optic Connector/10BaseFL Connection
The fiber optic card (E-FRL-SIC) provides one set of transmit (TX) and
receive (RX) ST connectors to fiber optic cable.
The redundant fiber optic card (E-FL/RED-SIC) provides a back-up fiber
optic connection by using two sets of transmit (TX) and receive (RX) ST
connectors to fiber optic cable.
Ensuring Correct 10BaseT Configuration
The 10BaseT cable and RJ-45 jacks for Hub to Terminal connections
must be configured as straight through. The 10BaseT cable and RJ-45
jacks for Hub to Hub connections must be configured as crossover.
NOTE: When installing the 1005 Hub using the MDI port, a crossover
cable is not needed. The MDI switch can be used to change the
straight through configuration to crossover at port 1.
The two active pairs
in a 10BaseT network
are pins 1 & 2 and
pins 3 & 6. Use only
dedicated wire pairs
(such as blue/white &
white/blue,
orange/white &
white/orange) for the
active pins.
