Key to Figure 19: Analog port card (MVX-A16) lights and controls
Feature Description
A
RESET button
Pressing the RESET button causes the card and all connected audio devices
to momentarily stop their current activity and to restart. The card’s “matrix
data” light goes off when the reset starts and comes back on when the reset is
complete.
During the reset, configuration information downloads to the card and its
connected audio devices from the CPU card. If the entire system is operating
except for one port card, or one or more panels connected to the card, press
the reset button for that card only.
Tip: The reset button is slightly recessed from the front panel to prevent it
from being accidentally pressed. A tool such as a bent paper clip is required to
press this button.

+12-Volt and -12-Volt Power Supply Lights
The matrix’s +12-volt and -12-volt power supplies provide electric current to
these two green lights. When lit, these lights indicate that the matrix’s +12-volt
and -12-volt power supplies are present and supplying electric current to the
card.
+5-Volt Power Supply Light
The matrix’s +5-volt power supply provides electric current to this green light.
When lit, the light indicates that the +5 supply is present and supplying electric
current to the card.
+3.3-Volt Power Supply Light
The matrix’s +3.3-volt power supply provides electric current to this green
light. When lit, the light indicates that the +3.3-volt supply is present and
supplying electric current to the card.
C
Active Lights
When lit, an active light indicates successful communication between the port
card and a connected device such as an intercom panel or interface.
Each of the port card’s 16 yellow active lights corresponds to one of 16 rear-
panel connectors or “ports” to which audio devices can be connected.
