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
