Power Supply
accept the AT-PWR11 power supply. Only the power supply that
matches the power requirements of the chassis will seat fully into
the power supply slot.
❑ Check that the management card is fully seated in the chassis. The
management card affects the LEDs on the power supplies. The
management card needs to be fully seated before the POWER LED
on the power supply can turn steady green.
Use the following guidelines to troubleshoot the AT-PWR10 AC Power
Supply:
❑ Check that the power cord is securely connected to the power
connector (at rear of the chassis) and to an appropriate power
source.
❑ Verify that the power outlet has power by connecting another
device to it.
❑ Try connecting the power supply to another power source. Or,
use a new power cord. Refer to
page 93.
❑ Check that the power cord is inserted into the IEC connector that
corresponds to the slot of the installed power supply. For
example, if the power supply is installed in slot Power A, then
plug the power cord into PWR A at the rear of the chassis.
❑ Remove all the line cards from the chassis, except the
management card. It may be that one of the line cards needs
repair and it is preventing the power supplies from coming up. If
the power supplies continue to have OFF POWER and FAULT
LEDs, then you may need to replace either the power supplies or
the management card.
Use the following guidelines to troubleshoot an AT-PWR11 DC Power
Supply:
