[j-nsp] Power budget detail command for data center SRX?

[Clarke Morledge]

I received a note off-line suggesting the "show chassis environment pem" 
command.   It will work on the SRX platform:

show chassis environment pem node 0
node0:
--------------------------------------------------------------------------
PEM 0 status:
   State                      Online
   Temperature                OK   35 degrees C / 95 degrees F
   AC Input:                  OK   120 Volts
   DC Output             Voltage   Current       Power    Load
                           12        24            288      24
PEM 1 status:
   State                      Online
   Temperature                OK   31 degrees C / 87 degrees F
   AC Input:                  OK   118 Volts
   DC Output             Voltage   Current       Power    Load
                           12        19            228      19

However, it does not give you any detail as to how much power is dedicated 
to a line card or how much each line card draws.  Surely, there must be a 
way to figure that out.  How else does the SRX know if it can bring a new 
component on-line?
