  • Page 2 ADTRAN Line Powered T200 or T400 Circuit Packs can be installed per cabinet. The cabinet system is pre- wired with surge arrestor boards to reduce installation and turn-up time. Wiring consists of either pre-wired cable stubs or pre-wired internal splice module connections depending on the model.

    (customer supplied) instead of lag screws for attaching the bottom pole mount support brackets to the H-frame. ADTRAN recommends the use of steel cross bars between the two poles to ensure adequate strength. The H-frame facility must be able to bear the weight of a fully-equipped cabinet (200 Lbs).
  • Page 9: Figure 11. Sealing Grommet Assembly

    CAUTION Ensure all grounds are securely connected to the cabinet ground buss and the ground lug connected to the most direct path to ground. The following procedures describe wiring connections for both the stubbed and module connection models: 1. Unscrew the security screws on the front and rear doors using a 7/16 inch nut driver or equivalent tool.
  • Page 10: Figure 12. Shield Connector Assembly

    NOTE Refer to Splice Module installation instructions for the length required inside the cabinet. Ensure sufficient sheathed cable exists at the top of the sealing grommet to install shield connectors. i. Using a wrench to hold the sealing grommet steady, use a second wrench to tighten the compression nut until the compression skirt creates a weathertight seal around the cable.
  • Page 11 III. SHRINK-WRAP After all other connections are completed, or correct wire lengths verified, complete the shrink-wrap process as follows: a. Position the shrink-wrap up against the bottom of the cabinet enclosing the entire sealing grommet assembly. b. Heat treat the shrink-wrap until properly constricted around the assembly.

  • Page 15: Testing

    3. TESTING General Each test identifies a particular malfunction. For that reason associated components used to isolate a malfunction are assumed to be functioning correctly. Certain troubleshooting requires personnel at both the Central Office to monitor the FPU, and field personnel at the cabinet to determine if a fault condition exists.
  • Page 16 3. Disable the front door switch by centering the rod and pulling outward. The secondary fan board Door LED should go Off and the Door Alarm LED at the FPU will turn green. Fan Operation When the cabinet is initially installed without heat generating circuit packs, the primary and secondary fans will not automatically turn On.
  • Page 17 If the cabinet has been opened during the day allowing the heat to escape before proper troubleshooting tests could be conducted, close the cabinet doors and allow the cabinet internal temperature to restabilize. Recheck during the hottest time of the following day before the outside temperature has a chance to drop.
  • Page 18: Maintenance

    Fan board repairs should not be attempted in the field. Repair services are obtained by returning the defective unit to ADTRAN Customer Service. Refer to Table 7 for a list of replacement item part numbers.
  • Page 19 6. Perform circuit tests to verify proper circuit operation. NOTE If lightning is the suspected cause of circuit pack failure, ADTRAN recommends replacing all the surge arrestor gas tubes. Door Gasket Replacement The door gasket provides a weathertight seal. Routine preventive maintenance includes cleaning the seal and seal area when the cabinet door is opened.
