Replacing the DMC-CPU with a DMC-CPU3
To replace the DMC-CPU with a DMC-CPU3, perform the following steps and refer to the
illustration below.
CAUTION: The DMC-CPU3 is susceptible to damage from electrostatic discharge
(ESD). Standard ESD precautions must be followed when handling the card.
Always wear an ESD wrist strap that is connected to ground and place the card on
grounded surfaces only.
NOTE: The DMC-CPU3 is not hot swappable. Always shut down the DigitalMedia
switcher before installing the card.
1. Remove the DMC-CPU card:
a. Disconnect the LAN cable from the card.
b. Using a #2 Phillips screwdriver (not included), loosen the two 6-32 x 3/4-inch
Phillips pan head screws that secure the card to the card assembly, and then
slide the card out of the slot.
2. Install the DMC-CPU3 card:
a. Carefully insert the card into the left and right guides of the CPU slot until the card
is 1/4 inch from the fully seated position.
b. Align the two included 6-32 x 3/4-inch Phillips pan head screws with the
corresponding holes in the card assembly, and then push the card inward until it
engages the chassis backplane.
c. Tighten the two Phillips screws to secure the card—do not overtighten
the screws.
