2. Remove the front, rear, and DS1 cable chamber covers from the
DDM-2000 OC-3 shelf.
NOTE
:
The covers must be installed later to assure compliance with electromag-
netic induction requirements. Also to ensure proper cooling when used with
a fan shelf.
3. Inspect the DDM-2000 OC-3 shelf for visible damage including bent or
touching backplane pins.
4. Determine the type of bay frame the DDM-2000 OC-3 shelf will mount in.
Position the DDM-2000 OC-3 shelf side mounting brackets (if necessary),
accordingly. Refer to Figure 3-6.
NOTE
:
To assure that the shelf is grounded through the bay frame, the mounting
brackets must be positioned so that the head of the mounting screw makes
contact with the unpainted surface of the bracket.
5. Position the side mounting brackets of the DDM-2000 OC-3 heat baffle
and/or fan shelf (if provided), accordingly. Refer to Figure 3-6.
