This advisory only affects operators using a CMM4 that supplies power to both 30V devices (PMP100 radios) and 56V devices (PMP430 or PMP320 radios). The new 30V replacement model ACPS120WA power supply does NOT require the 1k 5W resistor on the CMM4 29V terminals (This new 30V power supply was made available for order around December 3, 2010). The phased out 30V model ACPS112WA power supply will always require a 1k 5W resistor when a 56V supply is present. Since both power supplies look identical, see the label under the power supply to identify the model.

The current CMM4 power supply ( ACPS120WA) does NOT ship with a resistor. The phased out power supply, to the best of my knowledge from an email dated around 10/14/2009 from a Product Manager who has since left the company, we did not ship a resistor with the CMM4. We do have a supply of the 1k resistor in Tier-3 that we can ship the customer if the customer calls support for this specific issue.
Does this resistor come with the CMM4 or is there a seperate part number?
