Status LEDs, one bicolor:
Off—PIC 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
