1000BASE-LX Link/Act LEDs for the 1800-24T-LX-DC
Each 1000BASE-LX SC type fiber optic transceiver has two green LEDs, one to
indicate the status of the link between the Metro ESU 1800 and a remote network
device, and one to indicate that there is activity on the port (that is, packets are
being forwarded over the link). These LEDs are located to the right of each of the
two duplex SC 100BASE-LX fixed ports on the 1800-24T-LX-DC front panel
(see
Figure 11 ). Table 5 describes the LED status.

Warning:
Fiber optic equipment can emit laser or infrared light that can
injure your eyes. Never look into an optical fiber or connector port.
Always assume that fiber optic cables are connected to a light source.
