This section gives instructions for when AC Power is being utilized for powering the OLT6/1134 system.

The OLT6/1134 AC requires the AC-DC rectifier(s) to be installed in the rear of the unit.

Use the following procedure to install the redundant AC-DC rectifiers.

Note: The OLT6 can accommodate two rectifiers configured to support redundant powering.

 

1. Locate the package containing the rectifier/power supply.
2. Open the package and examine the rectifier for any apparent damage.
3. If damage is noted, do not proceed and contact TAC or your Tellabs sales representative for a replacement unit.
4. Remove the rectifier cover from the rear of the OLT6 shelf by removing the 2 securing knurled nuts and pulling the cover away from the chassis.
   
   
    
5. Prior to installing the first rectifier, use a #2 Phillips screwdriver and loosen the two captive screws on the two latches on either side of the rectifier and pull the top of the latches away from the rectifier.
   
   
6. Install the rectifier onto the top rectifier slot guide and fully insert the rectifier into the OLT6 chassis.
   
   
    
7. Close the latches and secure the 2 captive screws.
8. Install an AC power cable into the correct power input socket of the OLT. 
9. Observe the following rectifier activity.
10. Power LED illuminates.
11. Fan starts up.
12. The Minor and Major alarm LEDs illuminate momentarily as the rectifier logic stabilizes.
13. The rectifier should stabilize in approximately 8 seconds.
14. If a redundant power supply is being installed, repeat Step 1 through Step 13.
15. When the rectifier(s) is installed, replace the rectifier cover, ensuring that the metal sides of the cover are outside of the support guides.
