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 or blade)
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 "Slow Unison Blink Rate" on page 49) of all the
component indicators.
Unison Steady On
For the unison steady on, all indicators are simultaneously on steady (see "Steady
On" on page 46). This occurs during the front panel lamp test (see "Front Panel Lamp
Test" on page 45).
