DMB Series
DigitalMedia™ Blades
Installation Guide
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.
