WARNING: Use only an AC IEC 60320 C19 power cord with the AC power supply. Do not supply power to your system until you
install the power supplies, fan modules, RPMs, and line cards.
WARNING: The C9010 relies on the building's installation for short-circuit (overcurrent) protection. Dell Networking recommends
using a fuse or circuit breaker of 120 VAC, 20 A U.S. (240 VAC, 16 A international) for AC input on each power supply to ensure
its maximum power capacity.
WARNING: The C9010 does not have a main disconnect device. You must provide a suitable disconnecting device in the building
installation. Ensure you locate and install the device near the equipment and that it is easily accessible.
PSU Installation Procedure
1 Verify that the PSU switch is in the OFF (down) position.
2 Slide the rst power supply into the left-most power supply slot (PSU 0) until the latch (item 1 in Figure 24) snaps in place. For the
location of PSU slot numbers, see
C9010 Hardware Description.
3 Plug an AC power cord (IEC 60320 C19 cable) into the front of the power supply.
4 Plug the power cord into an AC power outlet. When the PSU switch is in the OFF (down) position, the PSU LED for AC input power
blinks green to indicate that the PSU is receiving power from the outlet.
5 Repeat Steps 1 to 4 to install additional AC power supplies of the same wattage. Install each additional power supply in the left-most
available PSU slot; for example, install the second power supply in PSU slot 1, the third power supply in PSU slot 2, and the fourth
power supply in PSU slot 3.
6 Install a blank to cover any open PSU slot.
