Extron Electronics MTPX Plus 6400 Series User Guide - Manual (Page 35)

Power
Apply power by connecting one or both power cords between the Primary and Redundant
AC power connectors and the AC sources. The switcher performs a self-test that flashes the
front panel buttons in a variety of patterns; then flashes all buttons green, red, and amber;
and then turns them either off or to background illumination. An error-free power up self-
test sequence leaves all control buttons either unlit or showing background illumination.
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 fails to respond
to commands or button pushes. If your switcher locks up on power-up, call the
Extron S3 Sales & Technical Support Hotline (see the
last page of this manual 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:
z z 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) ” for a detailed list of basic and
advanced functions and the procedure to set the various front panel locks.
