An SPCN cable might be the failing item.

1. Is the reference code 1xxx 1502, 1512, 1522, or 1532?
   • No: Continue with the next step.
   • Yes: Exchange the items in the following table one at a time:

     CCIN or FFC	Type and model	Part number	Description	Location code
     28BB	5790, 7311-D11	23R0181	I/O backplane	Un-P1
     	5790, 7311-D11	22R3958	Power supply	Un-Ex
     	0595, 5095, 7311-D20	39J0515	I/O backplane	Un-P1
     	0595, 5095, 7311-D20	39J2781	Power supply	Un-Ex
     520C	5796, 7314-G30	10N7677	I/O backplane	Un-P1
     	5796, 7314-G30	42R4491	Power supply	Un-Ex

     For all other units,

     • SPCN cables
     • Power distribution card

     This ends the procedure.

2. Is the reference code 1xxx 2612, 9012, 9013, 90F0, 9135, or C62E?
   • No: Continue with the next step.
   • Yes: The failing item is the SPCN frame-to-frame cable or adapter. The following list shows the possible failing items, and the cable or adapter lengths when appropriate: Use the following table to determine the part number for the field replaceable unit (FRU):

     CCIN or FFC	Type and model	Part number	Description	Location code
     1463		09P1251	SPCN cable (2 meters)
     1464		22R5219	SPCN cable (6 meters)
     1465		22R5221	SPCN cable (15 meters)
     1466		22R5222	SPCN cable 30.0 meters
     		21F9360	SPCN cable 60.0 meters
     0369		41U0128	SPCN optical cable (100.0 meters)
     1468		41U0129	Optical SPCN cable (250 meters)
     		39J3865	SPCN optical adapter

     This ends the procedure.

3. Is the reference code 1xxx9133?
   • No: Go to step 6.
   • Yes: Continue with the next step.
4. Verify that the expansion units are cabled correctly with both RIO/HSL cables and power network connections and that they are powered on and not indicating an error condition. Resolve any problems you discover. Does the SRC persist?
   • No: This ends the procedure.
   • Yes: Continue with the next step.
5. There might be a problem in the power network connection. Check the error log for another 1xxxxxxx SRC that was logged around the same time as the 1xxx9133 SRC. Is such an SRC present?
   • No: Contact your next level of support. This ends the procedure.
   • Yes: Return to the "Starting a service call" procedure in the system unit's service guide and service the 1xxxxxxx SRC to resolve this problem. This ends the procedure.
6. Is the SRC 1xxx9137 or 1xxx9138?
   • No: Return to the "Starting a service call" procedure in the system unit's service guide. This ends the procedure.
   • Yes: Continue with the next step.
     Note: If you are performing maintenance on your system and as a result are now experiencing a 1xxx9137 or 1xxx9138 reference code, ensure your maintenance actions did not cause the reference codes before replacing any additional parts. Ignore the 1xxx9137 or 1xxx9138 reference codes if you are doing concurrent maintenance on the affected expansion unit, RIO/HSL loop, or 12X HCA loop (InfiniBand technology) associated with the affected expansion unit, cable, or adapter.
7. Visually verify the following:
   • RIO/HSL or 12X HCA loop cables (InfiniBand technology) are connected and seated correctly.
   • If you are servicing a 9406-MMA or 9117-MMA, ensure the flex cables, if present, are connected and seated properly. Note that the flex cables are located on the front and back of the system.
   • All connected expansion units are powered on and not indicating an error condition.
     Note: If a problem is found during any of these checks, resolve that problem. If your system is still producing an SRC, continue with the next step.
8. If your system produced SRC 1xxx9137, check the error log for SRC B700698x (RIO/HSL) or B70069Ex (12X HCA loop) that was logged around the same time as SRC 1xxx9137. Did your system produce SRC B700698x or B70069Ex?
   • No: Go to the next step.
   • Yes: Return to the "Starting a service call" procedure in the system unit's service guide and resolve SRC B700698x or B70069Ex to solve the problem. This ends the procedure.
     Note: If your system produced SRC 1xxx9138, you have a faulty location code or vital product data. Contact your next level of support. This ends the procedure.
9. The SPCN firmware found more I/O resources than were found on the RIO/HSL loops and 12X HCA (InfiniBand technology) loops. This does not indicate an SPCN failure, even though the SRC was logged by the SPCN firmware; it indicates a problem in a RIO, HSL, or 12X HCA (InfiniBand technology) loop.

   A drawer’s serial number should have been reported with the 1xxx9137 SRC. Locate this drawer, the RIO/HSL or 12X HCA cables going to it, and the bus adapter in the system unit drawer to which those cables are attached.

   Exchange the following parts, one a time, until the problem is resolved:

   1. The RIO/HSL or 12X HCA (InfiniBand technology) cables going to the drawer.
   2. The RIO/HSL or 12X HCA (InfiniBand technology) adapter in the system drawer.
   3. The RIO/HSL or 12X HCA (InfiniBand technology) adapter in the I/O drawer.

   Use the following table to determine the part number for the field replaceable unit (FRU):

   CCIN or FFC	Type and model	Part number	Description	Location code
   	9406-MMA, 9117-MMA	See description	RIO, HSL, or 12X HCA (InfiniBand technology) loop cables. Refer to the Site and Hardware Planning manual, order number SA76-0091 for cable FRU part numbers.	Un-P1-Cx-Ty
   	9406-MMA, 9117-MMA	42R7352	I/O backplane	Un-P1
   	9406-MMA, 9117-MMA	39J0792	RIO/HSL-2 adapter	Un-P1-C8 or Un-P1-C9
   	9406-MMA, 9117-MMA	42R6849	Dual-port 12X Host Channel Attachment Adapter	Un-P1-C8 or Un-P1-C9
   	5790, 7311-D11	03N5633	RIO/HSL-2 adapter	Un-P1-C7
   	0595, 5095, 7311-D20	39J0523	RIO/HSL-2 adapter	Un-P1-C05
   	5796, 7314-G30	10N8782	Dual-port 12X HCA	Un-P1-C7

   Is the problem resolved?

   • No: Contact your next level of support. This ends the procedure.
   • Yes: This ends the procedure.
