9 The 10/100 Base-T Ethernet Port

The TS-5700 has a full-function IEEE 802.3 (10/100 Mbit/sec) Ethernet port provided by Davicom DM9102A
Ethernet controllers. The DM9102A is a single-chip, 32-bit PCI Ethernet controller that includes such features as
full-duplex operation, power saving shutdown modes, LED indicators for link status/activity (Green) and auto-
sense network speed detection (Amber). The physical interface is 10/100Base-T (RJ45 connector).
The TS-5700 has both a LINK/ACTIVITY LED and a 10/100 speed LED built into each RJ-45 connector that
indicates the current Ethernet status. The LINK LED (left side of connector, green) is active when a valid
Ethernet link is detected. This LED should be ON whenever the TS-5700 is powered on and properly connected
to a 10/100BaseT Ethernet network. The LINK/ACTIVITY LED will blink to indicate network activity either
inbound or outbound. The SPEED LED (right side of connector, amber) will be on when a 100 Mbit network is
detected and off for a 10 Mbit network. Both of these LEDs are controlled by the DM9102A and do not require
initialization by the processor.
