3.10 Connecting an interface cable
CAUTION:
After the interface cable connects to the switch, disconnect the interface cable if the port LED is green blinking.
Switch sends a great deal of broadcast packets or, there is a possibility which is being received. In this case, cut
off the network connection of equipment, and check the network and the configuration of the switch.

SFP/SFP+ port, and management Ethernet port.
3.10.2 Connecting a fiber optic-cable
CAUTION:
 Do not look in the port of each SFP/SFP+/QSFP+ transceiver module.
 Please check the RX/TX position of SFP/SFP+/QSFP+ transceiver module by the direction of RX/TX which
is ▲ or ↑.
1) Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is
well grounded.
2) Do clean a LC connector with a dedicated optical connector cleaner.
