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
