P2 Note:
Inhibits A, B and C (Pins 15, 20 and 24)
should each be connected to +5V Standbys A, B
and C, respectively (Pins 2, 7 and 11), through
10k ohm resistors. Pins 1, 3, 4, 6, 8, 9, 10, 12
and 13 function as I²C outputs when that function
is present.

For details on I²C data (Pins 1, 3, 4, 6, 8, 9, 10, 12 and 13), see Appendix 2. This module
addresses are pre-programmed in the rack: A is 00, B is 01 and C is 10.
15.3.8
The Module Present outputs (P2 pins 16, 21 and 25) are grounded when the module is
plugged in; otherwise they are open circuit.
