2.5.5.4-port 100M Electrical Interface Module (DS-4TXB)

The DS-4TXB module provides 4 100M fast Ethernet electrical interfaces. The physical interface is an RJ-45 connector and the C5 twisted pair cable is used whose transmission distance is 100 m. The MDI/MDIX self calibration function is supported. The cable length and peer interface type depend on the real situation.

1.1.1.23Structure of the DS-4TXB module

The front panel of the DS-4TXB module is shown in the following figure:

Figure 2-24 Front view of the DS-4TXB module

The front panel of the DS-4TXB module is composed of the following parts:

„4 RJ-45 10/100M Ethernet electrical interfaces

„4 ACT indicators

„4 LINK indicators

Of the above, the different states of LINK and ACT indicators show the port operating status. For details, refer to Table 2-17.

1.1.1.24Indicators of the DS-4TXB module

Table 2-17 Status definitions of the LINK and ACT LEDs on the DS-4TXB module

LED	Color	Display	Description
		state
LINK	Green	Solid on	After a stable connection between a port and the
			equipment is established, the indicator of the port
			stays solid on.
		Off	The link on the port is down.
ACT	Yellow	Flashing	Data are being received/transmitted on the port
		Off	No data are being received/transmitted on the
			port.
