Figure 1-6. 2 port 100Base-FX Module Front View
When installed into a MIL-S1000 switch, this Module
provides a 100Mbps Fast Ethernet fiber port which can be
used to:
# Connect the Switch to the backbone of your network;
that is, to a basement switch, hub or router
# Connect the Switch to a 100Mbps server or end-station
An ST, SC, MT-RJ or VF-45 connector provides the link to
the multi-mode fiber cabling and two indicators show the
status of the Module at-a glance. A DIP-switch sets the
operating mode to half duplex or full duplex (default).
