Service and Maintenance
Replace a Echo ACP
Step 1: Open enclosure door.
Step 2: If possible, save all configuration files to removable media. See “Save Arch
Configuration” on page 52. When the Echo ACP is hosted by a Unison DRd rack,
the Save Rack Configurations action also saves the dimming rack configuration
with the architectural configuration.
Step 3: Remove the existing Echo ACP from the rack.
a: Hold both sides of the Echo ACP and pull straight out.
Step 4: Insert the new Echo ACP into the enclosure.
a: Rest the Echo ACP on the bottom lip of the enclosure.
b: Slide the ACP into the rack.
c: Press on each corner of the ACP to ensure proper connection with the card
edge connector’s on the left and right I/O boards. If power is applied, the
status LEDs will illuminate when proper connection is made.
Step 5: If the Echo ACP is installed within a Unison DRd rack and a configuration
mismatch error occurs, select “Yes” to load the dimming configuration from the
DRd rack dimming engine. Alternatively you could select “NO”, then proceed to
load the rack configuration from the removable media. See “Load Dimming
Configuration” on page 51.
Step 6: Load the Echo ACP configuration from the removable media. See “Load
Architectural Configuration” on page 53.
Hardware Reset Switch
Reset the Echo ACP software and hardware by pressing the reset switch located on the
front panel of the unit. You can access this reset switch using the tip of a ball point pen, or
other pointed object.
During a powered reset the host rack holds levels for the last look played until the Echo
ACP has rebooted and takes control.
N o t e : If you don’t get a configuration mismatch error, the Echo ACP already has the
matching dimming rack configuration or it doesn’t have any dimming rack
configuration file and therefore automatically loaded the dimming configuration
from the DRd rack dimming engine.
