CPU module with TOD clock — EOL hot status
The 140CPU42402: It draws 1.8 A from the backplane bus and dissipates 9 W, so the rack power budget and thermal profile need to account for this module even in a legacy system. The time-of-day clock holds +/-8.0 seconds per day accuracy over 0 to 60 °C — adequate for timestamping events in batch or conveyor logic but not for high-precision synchronisation across distributed racks. Maximum of six NOM, NOE, and MMS modules (any combination) can be installed alongside this CPU, a limit that constrains network interface expansion in the same rack.
Sourcing reality — EOL, quoted to order
With the EOL Hot status, this CPU is sourced through independent surplus channels — quantities are lot-specific and confirmed at the time of RFQ.
