Troubleshooting Using Status Indicators
Single (Standby) Blink Rate
For the single blink rate, the indicator repeatedly flashes once at the beginning of a three second
interval. This indicates a system or component in Standby mode. For example, a server in
Standby power mode or a hot spare device waiting to be used (also used with amber indicators
to indicate a predicted fault).
Slow Unison Blink Rate
For the slow unison blink rate, the indicators on the component blink in unison for half a second
during a one second interval (1 Hz). Typically, this is limited to three successive blinks. This
confirms the successful insertion of a removable device (for example, a storage drive) into a
powered system (confirming the power connection).
Insertion Blink
The insertion blink is three successive blinks of a hot-swap component's primary status
indicator, for example, the green OK indicator. The insertion blink occurs immediately after
three successive unison blinks (see
component indicators.
