Note: Figure 3 shows a VPD pass-through card with two Ethernet ports. Some CEC enclosures have a VPD pass-through card with four Ethernet ports. The cards are functionally equivalent, and the LED definitions for Ethernet port link (index 4), Ethernet port activity (index 5), and CEC enclosure identify (index 6) remain the same.
