When installation is complete, perform the following checks to make sure the router is operating
properly:
• On the NV6257 power supply or the NCV8000 power supply, check that all 5 green power
LEDs on the front of each power supply module are lit. If any or all LEDs are off:
Check that the power supply module is fully seated in its slot.
Check the AC fuse on the PS6000 or the PS8010 power supply modules.
Check for +48 volts at each of the 5 front test points.
• On the NV8288 or the NV8288-Plus, check that the LEDs on the input cards, crosspoint cards,
control cards, and output cards are lit and indicating a “healthy” system. See Indicator LEDs on
page 58 for a list of normal and alert LED states.
• Make sure that the flow of air through the front of the router is unimpeded and the door is prop-
erly installed and closed. For more information, see Air Flow on page 59.
