each DSP must match the notch of the outline silk-screened on the card.
Check to see that all components on the card are seated securely in their sockets and
that no pins are bent.
Install the OPCs one at a time in any unused card slots. The component sides of the
OPCs must face right.
NOTE:
In tri-/quad-chassis installations where the third (slave) chassis is located away
from the first (master) chassis, be sure to install the OPC in the master dual-chassis if it
is used to provide additional Voice Processing channels.
After installing the OPC, the night transfer relay equipment, output device, Voice Pro-
cessing PC port, etc. may be connected to the card at any time.
