The procedure for bringing up the Multi-Bunch Feedback processor system for the first time in a new environment is a little involved and is documented below.

Preparing Hardware

• Michael Abbott The hardware list is ...

• The two FMC cards must be placed in the AMC 525 carrier in the correct slots, with the Digital I/O card in slot 0 and the FMC 500 in slot 1.  See the image below to verify the correct configuration:
  
• Note that in order to avoid an I₂C collision with an AMC temperature sensor (and thus a MTCA IPMI alert which won't go away) it is necessary to cut a line on the Digital I/O card (is this documented anywhere?
• When placing the AMC cards in the crate it seems that it is necessary to be careful about which cards are (logically) adjacent to the processor card.  To avoid problems, at DLS we have install the processor card in slot 6 and the carrier cards in slots 2 and 3 (note that these slot numbers don't correspond to the PCIe addresses which we'll encounter later).  Specifically, it seems that with the processor card in slot 6 we need to avoid placing a carrier card in slot 5, as otherwise the processor card tries to boot from non-existent mass storage in this slot!
• At this point we recommend that all serial ports are configured with the same data rate.  The default line speed is 115200 8N1 for all ports except for the CPU console which defaults to 9600 8N1.
• Now e-keying must be configured.

Table of relevant serial ports

E-key configuration

Once the hardware has been configured as above the crate can be powered on and the e-keying for the CPU and AMC525 must be set up.  This will be particularly important to ensure that the PCIe link works properly.

Ensure that the following are configured:

Note: Port 1 is enabled but not used.

AMC e-key

Connect to the MGT-RS232 port on the AMC525 front panel, and type ekey at the prompt.  Adjust for the following settings:

AMC525 > ekey

E-Keying configuration

  21) XAUI - Port 4-7                    22) XAUI - Port 8-11                 

Commands:
  1-22 to toggle option.
  save, cancel

Ensure that the following are configured:

Also the vadj setting must be configured as otherwise the FMC cards will not be powered on.

  FMC0 EEPROM is invalid / missing
  FMC1 VADJ range is 0.00V - 0.00V
  VADJ setting is 1.80V
AMC525 > vadj
0: 1.80V
c: Cancel
Select Voltage (0-0, c): 

If VADJ is not already set to 1.80V select 0 above to configure.

Cabling

Connections to Digital I/O card.

These are Limo ERA.00.250 sockets taking FFS.00.250 connectors.  All inputs are configured as 3.3V TTL high impedance (though 50Ω termination can be configured in software if desired), all outputs are driven as 3.3V TTL.  All inputs are acted on once per machine revolution in response to a rising edge, but are continuously sampled (at machine RF frequency).

Connections to FMC500 card

These are all SSMC sockets.  The connectors should not be tighter than finger tight, our experience is that over-tightening can use the inner conductor to lose contact.  The official documentation (see page 26) recommends 0.2 Nm coupling torque.
