3.2.4 Multi-power Input
Caution:
S3600-EI Series Ethernet Switches have both AC and DC power inputs, so ensure that
all the power connections are disconnected before you turn off the power.
3.3 Connecting Optical Fiber
Caution:
z
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.
z
Be sure to cover the protective cap within 10 seconds if an optical connector is not in
use to keep the optical connector clean.
z
Be sure to cover the protective cap if a PON interface has no optical connector
attached.
z
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.
