1.6.1 Connectors
The 3E07-04 includes four pairs of BNC barrel connectors for thin
coaxial cabling. Each of the four segments provides an internal BNC
T-connector, therefore an external T-connector is not required. The ATX
power supply provides the power for the module.
1.6.2 LEDs
The 3E07-04 contains a total of 10 green LEDs labeled RX and TX for
each segment, plus PROC and PWR for the module. The LEDs are
described in Chapter 5 of this manual.
1.6.3 Offline Button
Use the offline button before swapping the module, to take it offline until
the replacement is installed.

1.7 3E08-04 ETHERNET SWITCH MODULE
The 3E08-04 (Figure 1-4) provides connection for four independent
multimode 10BASE-FL LANs to the ATX backplane and packet
processing module. It includes processing circuitry for receiving and
forwarding packets between the connected 10BASE-FL LANs. The
3E08-04 contains several LEDs to indicate the module’s operational
status.
The 3E08-04 supports Ethernet and the IEEE 802.3 10BASE-FL
specification.
