Complete the following steps:

1. Is more than one device attached?
   • No: Continue with the next step.
   • Yes: See the device documentation for information about setting the device address. This ends the procedure.
2. Is the attached device in the system unit?
   • No: Continue with the next step.
   • Yes: Use symbolic FRU BACKPLN to determine which signal cables to replace. This ends the procedure.
3. Is the attached device a 358x device?
   • No: Continue with the next step.
   • Yes: For specific 358x attachment cable information, refer to the specific device and model service documentation, or contact your next level of support. This ends the procedure.
4. Find the IOA type:
   1. Find the IOA location.
   2. Use the location information of the IOA in the service action log if it is available. If the location is not available, find the address. See the System reference code format description. Use the address to find the location. See Part locations and location codes.
   3. Find the IOA card in the system and read the type number of the card at that location.
5. Find the IOA type, the attached device, the cable length, and the cable part number in the following list.
6. Verify that the part number in the list is the same as the part number on the cable.
7. For external devices that are not found in the following list, use the device type and see the appropriate service documentation for that device. The service documentation for that device will help you determine the FRU part numbers and replacement procedures you are to use during this repair action. If you are unable to locate the documentation for your specific device, contact your next level of support for assistance.

   IOP or IOA Type	Device	Lengths	Part Number
   2782, 5702, 5703, 571A	7206/VX2, 7207/122, 7208/345, 7210/020, 7210/025	1.5 meters	19P4508, or 19P4506 with 19P0482 interposer cable. For other device types, see the device documentation to determine cable part numbers.
   2782, 5702, 5703, 571A	7206/VX2, 7207/122, 7208/345, 7210/020, 7210/025	2.5 meters	19P0279, or 35L1307 with 19P0482 interposer cable. For other device types, see the device documentation to determine cable part numbers.
   2782, 5702, 5703, 571A	7206/VX2, 7208/345	4.5 meters	19P0050 For other device types, see the device documentation to determine cable part numbers.
   2782, 5702, 5703, 571A	7206/VX2, 7208/345	10 meters	19P0048 For other device types, see the device documentation to determine cable part numbers.

   Notes:

   • All cables for the 9427 tape library must include an interposer (part 05H3834) on the device end of the cable.
   • All cables for the 3996 and 399F attachment are the responsibility of the external device service.
   • For specific 358X attachment cable information, see the specific device and model service documentation, or contact your next level of support.

This ends the procedure.
