5.4.3 Gigabit Switch LEDs
Each LED (24 in total) corresponds to a port (the number of which is shown on the
air‐cooled front panel), as shown in Figure 5‐3.
The LEDs, which all have the same meaning, can be used to quickly diagnose a port
link failure, but for full diagnostics, use the Ethernet interface or serial terminal.
Table 5‐2 shows the LED meanings.
