[j-nsp] MPC7E-MRATE - won't come online (enhanced-ip done)

[Aaron Gould]

This one was interesting...the high capacity PEM's operate in 1700 w mode
with what I think is the default dip switch position zero (0) as opposed to
1, which allows it to operate at 4100 w

agould at lab-960> show chassis power | grep "feed|PEM"

PEM 0:
  DC input:  OK (1 feed expected, 2 feed connected)

PEM 1:
  DC input:  OK (1 feed expected, 2 feed connected)

PEM 2:
  DC input:  OK (1 feed expected, 2 feed connected)

PEM 3:
  DC input:  OK (1 feed expected, 2 feed connected)


While I was trying to slot the MPC7E-MRATE card in slot 1 and 10, I got
these messages about needing 465w but only 55 or 455 remaining...

agould at lab-960> show chassis power | find "System"
System:
  Zone 0:
      Capacity:          1700 W (maximum 4100 W)
      Allocated power:   1245 W (455 W remaining)
      Actual usage:      576 W
  Zone 1:
      Capacity:          1700 W (maximum 4100 W)
      Allocated power:   1645 W (55 W remaining)
      Actual usage:      846 W
  Total system capacity: 3400 W (maximum 8200 W)
  Total remaining power: 510 W

So apparently the MPC7E-MRATE needs 465 watts to boot, and it didn't find
enough power.

it was trying to tell me that I have 2 power feeds and the dip switch is set
to only allow 1.

-----------------------------------------

I just found out that there is a dip switch on the back of my high-capacity
PEM's that needs to be flipped from 0 to 1 for the additional power feed I
have going into it.  Show log chassisd shows my fpc asking for power but my
system doesn't have enough.
