After a switch starts, the PON interface may emit invisible
radial when there is no optical connector connected to it and
the protective cap is removed from it. Therefore, do not stare
into the optical interface.
Be sure to cover the protective cap within 10 seconds if an
optical connector is not in use to keep the optical connector
clean.
Be sure to cover the protective cap if a PON interface has
no optical connector attached.
Place the protective caps in a safe place when a PON
interface has fiber connected to prepare for the cases the fiber
is pulled out.
3.4 Connecting the Switch to a Console Terminal
3.4.1 Console Cable
Console cable is an 8-core cable. At one end of the cable is a crimped RJ-45 connector for the connection to the Console port
of the switch; at the other end of the cable are one DB-9 (female) connector for the connection to the serial port on the console
terminal. See Figure 3-22.

3.4.2 Connecting the Console Cable
Follow these steps to connect a terminal device, a PC for example, to the switch:
Step 1: Plug the DB-9 (female) connector of the Console cable to the serial port of the PC where the switch is to be configured.
Step 2: Connect the RJ-45 connector of the console cable to the Console port of the switch.
