Front panel security lockouts

In the procedural descriptions that follow, it is assumed that the switcher is in Lock mode 0 (fully unlocked). The following two Lock modes are also available:

•Lock mode 1 — All changes are locked from the front panel (except for setting Lock mode 2). Some functions can be viewed.

•Lock mode 2 — Advanced features are locked and can be viewed only. Basic functions are unlocked.

NThe switcher is shipped from the factory in Lock mode 2.

See “Setting the front panel locks (Executive modes)” on page 3-52 for a detailed list of basic and advanced functions and the procedure to set the various front panel locks.

Power

Apply power by connecting the power cord to an AC source. The switcher performs a self-test that flashes the front panel button indicators green, red, and amber and then turns them off. (The order in which the colors are displayed depends on the model.) An error-free power up self-test sequence leaves all I/O and control buttons either unlit or showing background illumination. The lit/unlit status of the RGBHV or Video button and the Audio button is defined by the system configuration as follows:

•Audio models — RGBHV/Video and Audio both lit

•Models without audio — RGBHV/Video lit and Audio unlit

The current configuration and all presets are saved in non-volatile memory. When power is applied, the most recent configuration is retrieved. The previous presets remain intact.

If an error occurs during the self-test, the switcher locks up and does not operate. If your switcher locks up on power-up, call the Extron S3 Sales & Technical Support Hotline.
