I have some MX480's that I am trying to test, and I am currently only able to provide power for one of the power supplies. If I hook up power to PEM0 or PEM2. I am able to get the system to power on and boot up. However I can not get the the DPCE 40x 1GE R to show up when I do a show chassis hardware. Is the reason why it is not showing up is do to the chassis being under powered, or is it that the slot that the card is in needs to turned up?
