J
Reset button — (DXP 42 only) This recessed button initiates four levels (modes) of
reset on the DXP switcher (see figure9,
J
, on page 16). To initiate the different reset
levels, use a pointed object such as a small Philips screwdriver or a stylus to press
and hold the button while the switcher is running or while it is being powered up (see
Resetting on page32).
Powering On
Apply power as follows:
• DXP 44, 84, and 88 — Connect the provided IEC power cord to the rear panel IEC
connector (figure3,
I
, on page 7) and to an AC source.
• DXP 42 — Connect the provided 12 V, 1.5 A power supply to the rear panel 2-pole
captive screw connector (see figure4,
I
, on page 8).
Self-test
When power is applied to the DXP, the switcher performs a self-test as follows:
• DXP 44, 84, and 88 — The front panel input, output, and I/O button LEDs blink red,
then green, while the control button LEDs blink green. All LEDs turn off except the I/O
LEDs, which light steadily red for several seconds. The I/O LEDs remain lit red while a
self-test is performed, during which the green Input Signal and HDCP LEDs also light in
order in a clockwise circling pattern. If error-free, the self-test ends with only one of the
I/O LEDs lit, reflecting the previous selection of audio or video. If an error occurs during
the self-test, the DXP locks up and does not operate. If this occurs, call the Extron
S3 Sales & Technical Support Hotline (see the last page of this guide for contact
information in your area).
The current configuration, EDID information, and all presets are saved in memory. When
power is applied, the most recent configuration is retrieved. The previous presets remain
intact. The switcher powers up in full power mode (neither power save mode enabled).
• DXP 42 — All the front panel button LEDs blink. After the power up sequence is
completed, the button LEDs turn off. The Signal and HDCP LEDs light according to the
current state of each input.
