Of the above, the different states of LINK and ACT indicators show the port operating status. For details, refer to Table 2-13.

1.1.1.18Indicators of the DS-2FMM module

Table 2-13 Status definitions of the LINK and ACT LEDs on the DS-2FMM 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
			optical port.
		Off	No data are being received/transmitted on the
			optical port.

2.5.4.2-port 100M Single-mode Optical Interface Module (DS-2FSM)

The DS-2FSM module provides 2 100M single-mode fast Ethernet optical interfaces. The physical interface is a standard SC optical interface and the single-mode fiber is used whose maximum transmission distance is 15 km. Two pairs of single-mode fibers are required for it. The fiber length and peer interface type depend on the real situation.
