My AMC13 is plugged in but I can't contact it!

If you have an NAT MCH, you can learn a lot about the state of your AMC13 (or other MicroTCA module) with the show_sensorinfo command. First, connect to your MCH using telnet:

[cms2] /home/hazen/amc13_python/src_amc13 > telnet
Connected to
Escape character is '^]'.

Welcome to NAT-MCH

nat> show_fru

FRU Information:
 FRU  Device  State  Name
  0   MCH      M4    NMCH-CM
  3   mcmc1    M4    NAT-MCH-MCMC
  8   AMC4     M4    AMC13
 13   AMC9     M4    AMC13
 30   AMC13    M4    AMC13
 40   CU1      M4    VT VT095
 41   CU2      M4    VT VT095
 50   PM1      M4    VT UTC010
 60   Clk1     M4    MCH-DTC

The show_fru command lists the "field replaceable units" (i.e. cards) plugged in to the crate. It knows about AMC13's, so they appear by name (in fact it currently mis-identifies MiniCTR2 as AMC13!). We have a MiniCTR2 in slot 4, an AMC13 in slot 9 and another AMC13 in the MCH2 sigte (FRU 30).

nat> show_sensorinfo 30
Sensor Information for AMC 13
  #   SDRType  Sensor Entity Inst  Value   State  Name
  0   MDevLoc          0xc1  0x7a                 AMC13
  0   Full     0xf2    0xc1  0x7a  0x01        Hotswap
  1   Full     Temp    0xc1  0x7a  33.6    ok     Amb. Temp
  3   Full     Voltage 0xc1  0x7a  12.544  ok     +12V
  4   Full     Voltage 0xc1  0x7a  3.2688  ok     +3.3V BkEnd
  5   Full     Voltage 0xc1  0x7a  1.1932  ok     T2 1.2V
  9   Full     0xc0    0xc1  0x7a   0x83     0x00  GPIO 7:0

The Hotswap sensor indicates the state of the switch connected to the handle (actually, the MMC state machine driven by it). When the module is correctly plugged in and the handle pushed in, it should read 0x01 as above. The values gleaned from the MMC firmware listing are as follows:

(bit values given as an 'or' in the readout):

  01 - handle closed
  02 - handle open
  04 - quiesced (??)
  08 - backend power failure
  10 - backend power shutdown

Also, the +12V should read something like 12V.

Point 5 Test Crate

Some helpful hints from Jim.

from hcaldaq12:

(this gets you a list of commands)

(this gets you list of modules)

pwr_off 30
(power off module no. 30)

pwr_on 30
(power on module no. 30)
