Introduction
The MIL-SME801P and MIL-SME801G advanced managed switch families are
multi-port switches that can be used to build high-performance workgroup
networks and as Customer Provider Edge (CPE) devices in Fiber-to-the-Home
(FTTH) networks.
Figure 1-1. The MIL-SME801P switch
The MIL-SME801P switch has eight auto-sensing 10/100BASE-TX RJ-45 ports
plus one 100BASE-FX fiber port that enables long-distance connections. The
MIL-SME801G switch has eight auto-sensing 10/100BASE-TX RJ-45 ports plus one
1000BASE-X fiber port in either SX or LX optic types
. The switch features a
“store-and-forward “ switching scheme. This allows the switch to auto-learn
and store source address in a 6K-entry MAC address table.
An
MDI
(Medium Dependent Interface) Port is also called an “uplink” port.
This means that the wiring is configured to connect to a hub, switch or router.
An MDI-X Port swaps the transmit and receive pins so that it is able to
communicate with an MDI device. An auto MDI/MDI-X port senses how the
device it is connected to is configured and automatically configures it to work
with that device. So, if it receives data on pins 1 and 2, it knows it needs to
transmit on pins 3 and 4. This eliminates the need of having multiple patch
cable types.
In order to improve readability, for the remainder of this document the phrase
MIL-SME801P will be used to refer to both the Fast Ethernet and Gigabit Ethernet
fiber port versions of the product. Where the document refers to 100FX and you are
installing the MIL-SME801G, read this as 1000FX.
