Installing a Power SupplyThe C9010 has four power supply slots at the bottom of the front of the chassis. The C9010 supportsonly an AC power supply with an IEC 60320 C19 power cable. The power supply is rated as 1450W at100~120 VAC and 2900W at 200~240 VAC.NOTE: If a power supply fails, Dell Networking recommends that you replace it as soon as possible.C9010 power supply units are hot-swappable.PSU Installation Guidelines• The C9010 requires at least one power supply for normal operation. Dell Networking recommendsusing additional power supplies for redundancy and additional power depending on the local powergrid voltage (100-120 VAC /200-240 VAC).• C9010 power supplies do not support a combination of power grid types. For example, all PSUs mustbe powered either by 100~120 VAC or 200~240 VAC, but not both. Do not mix utility input.• To protect against high-voltage shock, install a power supply blank in all unused power supply slots.• Connect the AC power supply to the appropriate branch circuit protection as defined by your localelectrical codes.• Verify that the remote power source complies with the system input power specifications.WARNING: Use only an AC IEC 60320 C19 power cord with the AC power supply. Do not supplypower 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 powercapacity.WARNING: The C9010 does not have a main disconnect device. You must provide a suitabledisconnecting device in the building installation. Ensure you locate and install the device near theequipment and that it is easily accessible.PSU Installation Procedure1. Verify that the PSU switch is in the OFF (down) position.2. Slide the first power supply into the left-most power supply slot (PSU 0) until the latch (item 1 inFigure 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, thePSU 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 eachadditional power supply in the left-most available PSU slot; for example, install the second powersupply 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.Installing the Hardware 33
