[c-nsp] Power Supply 2 ouput has dropped

[quinn snyder]

what version of code are you running?  
i ran into something similar with c6509 running sxj.  something to do with an invalid pointer or something during the sharing of values between the peers.  power supplies were 3kw powered by 240v pdu's off a 415v buss.  even during proper operation of the pdu -- confirmed with a multimeter for current and voltage -- the p/s would show ~ ½ available power.

eventually upgrading to a later sxj release fixed the issue.  cisco has a posted ddts -- internally at last check -- for this.  hit up your account team for details.

regards,
q.
