Reassembling the Profile Chassis
To reassemble the Profile chassis:
1. Apply stick-on labels on the Profile chassis rear panel to help identify all new
board locations (see Figure 10).
2. Bundle any loose cables with the tie wraps provided.
3. Use the Torx tool with the T10 tip to reinstall the rear board hold-down
bracket (see Figure 3 on page 11). Make sure that boards in the chassis fit
into the grooves in the bracket.
CAUTION: To prevent damage to an Analog Composite Monitor board, do
not install a short board extension on the front hold-down bracket at the
Monitor board location.
4. If necessary, move or remove any short board extensions on the front board
hold-down bracket. Then use the Torx tool with the T10 tip to reinstall the
bracket (see Figure 3).
5. Use the Torx tool with the T10 tip to reinstall the rear chassis cover with the
screws previously removed.
NOTE: When reinstalling rear and front chassis covers, start all the screws
before tightening them. This ensures that the screw threads are properly
aligned, and will help avoid stripping threads or breaking screws.
6. Use the Torx tool with the T10 and T15 tips to reinstall the front chassis
cover with the screws previously removed.
7. Reinstall the Profile chassis in the rack and reconnect as labeled all external
cables previously removed.
8. Apply power to the Profile system and check the presence of the MPEG
boards with the procedure under “Installation Verification” on page 29.
