CEC enclosure LED indicators (Models 941, 951)

This section contains FRUs that have LED indicators. Each listed assembly is shown with a description of its LEDs. While CEC enclosure LED indicators might indicate a failure, they should not be used as a starting point for a repair.

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.
