Insertion Blink
The insertion blink is three successive blinks of a hot-swap component's primary status
indicator (for example, the green system OK indicator). The insertion blink occurs immediately
after three successive unison blinks (see "Slow Unison Blink Rate" on page 46) of all the
component indicators.
Unison Steady On
For the unison steady on, all indicators are simultaneously on steady (see "Steady
On" on page 44). This occurs during the front panel lamp test (see "Front Panel Lamp
Test" on page 43).
