Status LED, one bicolor:

■

Off—PIC is not enabled

■

Green—PIC is operating normally

■

Red—PIC has an error or failure

Port LEDs, one pair per port:

■

Link—If green, the port is online; if there is no light, the port is down

■

Activity—If flashing green, the port is receiving data; if there is no light, the port might

be on but is not receiving data
