Operating the SAN Director 2/128 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 To determine the status of a 16-port card: 1. Check the LED indicators on the port card (see Figure 15). The LED patterns may temporarily change during POST and other diagnostic tests. For information about how to interpret the LED patterns, refer to Table 6. 2. Check the 16-port card status using the slotshow command (see Obtaining Chassis and Component Status, page 99 for an example). 80 SAN Director 2/128 Installation Guide
