To add or replace a DMB I/O blade, perform the following steps and refer to the
illustrations below.
1. Do either of the following:
• If adding an I/O blade, remove the slot cover of an unused input or output slot as
appropriate by loosening the two thumb screws.
• If replacing an I/O blade, disconnect all cables from the blade being replaced,
loosen the two thumb screws that secure the blade to the blade assembly, and
then slide the blade out of the slot.
2. Carefully insert the new blade into the guides at the top and bottom of the selected
slot until the blade is 1/4 inch from the fully seated position.
3. Align the two thumb screws of the blade with the corresponding holes in the blade
assembly, and then push the blade inward until it is fully seated and engages the
chassis backplane.
4. Finger-tighten the two thumb screws to secure the blade—do not overtighten the
screws.
5. Reconnect the cables to the blade.

CAUTION: DMB I/O blades are susceptible to damage from electrostatic discharge
(ESD). Standard ESD precautions must be followed when handling the blades. Always
wear an ESD wrist strap that is connected to ground, and place blades on grounded
surfaces only.
NOTE: DMB I/O blades are hot swappable; therefore, the blades can be installed
without the need to shut down the DigitalMedia switcher.

Replacing the DMB CPU Blade
The DMB-4K-CPU-64 blade occupies the CPU slot of the DM-MD64X64; the
DMB-4K-CPU-128 blade occupies the CPU slot of the DM-MD128X128.
NOTE: The information in this section also applies to the DMB-CPU-64 and
DMB-CPU-128 blades, which are earlier models of the DMB-4K-CPU-64 and
DMB-4K-CPU-128 blades, respectively.
Refer to the following illustrations for the location of the DMB CPU blade in a
DM-MD64X64 and DM-MD128X128.

To replace the DMB CPU blade, perform the following steps and refer to the illustration
below.
CAUTION: The DMB CPU blade is susceptible to damage from electrostatic discharge
(ESD). Standard ESD precautions must be followed when handling the blade. Always
wear an ESD wrist strap that is connected to ground, and place the blade on a
grounded surface only.
1. Disconnect all cables from the blade, loosen the two thumb screws that secure the
blade to the blade assembly, and then slide the blade out of the slot.
2. Carefully insert the new blade into the guides at the top and bottom of the CPU slot
until the blade is 1/4 inch from the fully seated position.
3. Align the two thumb screws of the blade with the corresponding holes in the blade
assembly, and then push the blade inward until it is fully seated and engages the
chassis backplane.
4. Finger-tighten the two thumb screws to secure the blade—do not overtighten the
screws.
5. Reconnect the cables to the blade.
NOTE: If the DMB-CPU-64 blade is being replaced with a DMB-4K-CPU-64 blade or if
the DMB-CPU-128 blade is being replaced with a DMB-4K-CPU-128 blade, be sure to
upgrade the rmware of all DMB I/O blades in the switcher. The latest rmware le can
