Extron electronic 450 manual Power, Front Panel Security Lockouts

Power

Apply power by connecting the power cord between the switcher and an AC source. The switcher performs a self-test that flashes the front panel button indicators red, green, and amber and then turns them off. An error-free power-up self-test sequence leaves all input, output, and control buttons either unlit or showing background illumination. The lit or unlit status of the RGBHV or Video button and the Audio button is defined by the system configuration as follows:

•Audio models — RGBHV or Video and Audio both lit

•Models without audio — RGBHV or 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 and Technical Support Hotline. See the end of this guide for the phone number in your region of the world.

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.

NOTE: The switcher is shipped from the factory in Lock mode 2. See Setting the Front Panel Locks (Executive Modes) on page 75 for a detailed list of basic and advanced functions and the procedure to set the various front panel locks.
