HP E5500-48-POE, 5120 SI, 5120 48G, 5120 EI manual Seven-segment LED description

Page 83

The seven-segment LED can also show the total PoE output power as a percentage of the maximum PoE output power that a PoE switch can supply (see Table 24). The PoE switches include 5120-24G-PoE+ EI (2 slots), 5120-24G-PoE+ EI TAA (2 slots), 5120-48G-PoE+ EI (2 slots), and 5120-48G-PoE+ EI TAA (2 slots).
