5.MAINTENANCE
5.1The ACT PSU requires no routine maintenance to operate properly.
The faceplate has two faceplate fuses. If a fuse blows, a colored pin becomes visible from the front of the channel bank. To remove a fuse, grasp it and firmly pull it from the holder. To insert a fuse, push it into the holder until it firmly seats.
5.2ADTRAN does not recommend that repairs be performed in the field. Repair services may be obtained by returning the defective unit to the ADTRAN Repair Department (see subsection 6.2).
