As one of the three supported form factors for FAIR Beam Instrumentation µTCA was chosen. The main advantages of µTCA systems are the high bandwidth for very high data rates and the full remote control features. The standard was enhanced by DESY and other high energy physics labs to the MTCA.4 specification for Physics. This form factor could get a successor for VME.
Envisaged are DAQ systems for fast sampling ADCS eg BPM systems, scaler systems for higher sampling rates and video imaging systems.
The main standard MTCA-4 system consists of:
Get M State via sensor: Example: Handle pulled out = M1 - board gets only management power
$ ipmitool -I lan -H <mch_ip_addr> -A none sensor get "HS 009 AMC5"
Locating sensor record…
Sensor ID : HS 009 AMC5 (0x3c)
Entity ID : 193.101
Sensor Type (Discrete): PICMG FRU Hotswap
States Asserted : FRU Hot Swap
[Transition to M1]
Example 2: Handle pushed in (M4) - board is on
$ ipmitool -I lan -H <mch_ip_addr> -A none sensor get "HS 009 AMC5"
Locating sensor record…
Sensor ID : HS 009 AMC5 (0x3c)
Entity ID : 193.101
Sensor Type (Discrete): PICMG FRU Hotswap
States Asserted : FRU Hot Swap
[Transition to M4]
Switch of dedicated FRU:
$ ipmitool -I lan -H <mch_ip_addr> -A none picmg deactivate <fru_id>
Switch it on:
$ ipmitool -I lan -H <mch_ip_addr> -A none picmg activate <fru_id>
Cold reboot of complete system:
$ ipmitool -I lan -H <mch_ip_addr> -A none chassis power reset
Warm-reboot:
$ ipmitool -I lan -H <mch_ip_addr> -A none chassis power cycle
