Troubleshooting Using Status Indicators
Slow Blink Rate
For the slow blink rate, the indicator (typically green) repeatedly lights for half a second during
a one second interval (1 Hz) and turns off for half a second. The slow blink rate indicates an
on-going activity, for example, device rebuilding, booting, or in transition from one mode to
another.
Fast Blink Rate
For the fast blink rate, the indicator repeatedly blinks twice (on, off, on) during a one second
interval (2 Hz). The fast blink rate indicates activity or data transfer.
