Interpreting Led Activity; 16-Port Cards - HP StorageWorks 2/64 - Core Switch Installation Manual

Interpreting LED activity

System activity and status can be determined through the activity of the LED indicators on the
switch. There are three possible LED states:
• No light
• Steady light, in one of the following colors:
• Green
• Orange (also referred to as amber in related documentation)
• Yellow (appears when both green and orange LED elements are lit)
• Flashing light (green, orange, or yellow)
The LEDs may flash green, yellow, or orange while the switch is booting or while POST or other
diagnostic tests are running. This is normal, and does not indicate a problem unless the LEDs
do not indicate that all components are operational after boot process, POST, and any
diagnostic tests are complete.

16-port cards

1. Check the LED indicators on the port card (see
The LED patterns may temporarily change during POST and other diagnostic tests. For
information about how to interpret the LED patterns, refer to
2. Check the 16-port card status using the slotShow command (see
