CP3004-SA
4.4 Maximum Power Consumption of XMC Modules
A maximum power of 15 W is available on the XMC slot (located on the CP3004-XMC module) and it can
be arbitrarily divided on the 3.3 V and 5 V (VPWR) voltage lines. XMC modules are based on 3.3 V power
along with variable power (VPWR) defined as either 5 V or 12 V in the ANSI/VITA 42.0-200x XMC
Switched Mezzanine Card Auxiliary Standard specification. On the CP3004-SA, the VPWR is configured
to 5 V.
The following table indicates the current of a XMC module.
Note:
XMC integrators should carefully review the power ratings, cooling capacity and airflow re-
quirements in the application prior to installation of an XMC module on the 8 HP CP3004-
SA with CP3004-XMC extension module.
4.5 Current Limits
The CP3004-SA has a hot swap controller for the +3.3V and +5V input voltage. The trip current limits in
case of catastrophic failure are:
»
+3.3 V: 16.5 A minimum, 21.9 A maximum
»
+5 V:
33.0 A minimum, 43.8 A maximum
The maximum thermal operating current is 11.0 A for the +3.3 V supply and 17.6 A for the +5 V supply.
The customer configuration/application shall not exceed these limits for a maximum operating ambi-
ent temperature of 60°C.
