Interpreting LED activity
System activity and status can be determined through the LEDs on the switch. There are
three possibl
e LED states that display either green or amber:
• Asteadylight
• Aflashinglight
• No light
LEDs display either green or amber colors. A steady green light indicates a healthy
state. Sometimes, the LEDs flash any of the colors during boot, POST, or other diagnostic
tests. This is normal; it does not indicate a problem unless the LEDs do not indicate a
healthy sta
te after all boot processes and diagnostic tests are complete.
4/8 and 4/16 SAN Switch LEDs
The LEDs are shown in Figure 2 3.
Figure 2 3 shows the LEDs on the port side of the 4/16 SAN Switch.
