Summary

Yesterday I unpacked and installed the three 18-bit DAC cards received from Hanford. I then repeated the low-level PCIe testing outlined in T1900700, which is expanded upon below. I did not make it to DAC-ADC loopback testing because these tests in fact revealed a problem with the new hardware. After a combinatorial investigation that involved swapping cards around between known-to-be-working PCIe slots, I determined that one of the three 18-bit DAC cards is bad. Although its "voltage present" LED illuminates, the card is not detected by the host in either I/O chassis.

I installed one of the two working DACs in the c1bhd chassis. This now 100% completes this system. I installed the other DAC in the c1sus2 chassis, which still requires four more 18-bit DACs. Lastly, I reran the PCIe tests for the final configurations of both chassis.

PCIe Card Detection Tests

For future reference, below is the set of command line tests to verify proper detection and initialization of ADC/DAC/BIO cards in I/O chassis. This summarizes the procedure described in T1900700 and also adds the tests for 18-bit DAC and 32-channel BO cards, which are not included in the original document.

Each command should be executed on the host machine with the I/O chassis powered on:

$ sudo lspci -v | grep -B 1 xxxx

where xxxx is a four-digit device code given in the following table.

Device Device Code
General Standards 16-bit ADC 3101
General Standards 16-bit DAC 3120
General Standards 18-bit DAC 3357
Contec 16-channel BIO 8632
Contec 32-channel BO 86e2
Dolphin IPC host adapter 0101

The command will return a two-line entry for each PCIe device of the specified type that is detected. For example, on a system with a single ADC this command should return:

10:04.0 Bridge: PLX Technology, Inc. PCI9056 32-bit 66MHz PCI IOBus Bridge (rev ac)
             Subsystem: PLX Technology, Inc. Device 3101
