NOTE: Non-Dell qualified 40G transceivers are not supported on the C9010. If you insert a non-Dellqualified 40G transceiver into a C9010 40GbE port, the switch places the interface in an error-disabled (operationally down) state and generates a syslog message, such as: %C9000LC0640:8%IFAGT-2-TRANSCEIVER_UNSUPPORTED_ERROR: Transceiver in slot 8 port 4unrecognized, putting interface in operational-down state.WARNING: When working with optical fibres, follow all the warning labels and always wear eyeprotection. Never look directly into the end of a terminated or unterminated fibre or connectoras it may cause eye damage.CAUTION: ESD damage can occur if the components are mishandled. Always wear an ESD-preventive wrist or heel ground strap when handling the switch and its components.1. Position the transceiver correctly over a port. The transceiver has a key that prevents it from beinginserted incorrectly.2. Insert the transceiver into the port until it gently snaps into place.Powering Up the SystemBefore you supply power to the chassis, Dell Networking recommends that you re-inspect yourequipment rack and chassis.Before Powering UpVerify that:• The equipment is properly secured to the rack.• The equipment rack is properly mounted and grounded.• The ambient temperature around the unit (which may be higher than the room temperature) is withinthe limits specified for the C9010. The supported operational temperature is 32° to 113°F (0°C to45°C). For more detailed environment requirements, see Technical Specifications.• The airflow into the vents on the right side and out of the vents on the left side of the chassis isunobstructed.• All protective blank covers are in place.• The input circuits are correctly sized for the loads and you use sufficient over-current protectiondevices.• Each AC power supply unit is correctly installed. The switch on each AC power supply is in the OFF(down) position.CAUTION: Do not power up the switch if no fan module is installed.CAUTION: The switch has a high line-voltage requirement of 200V.NOTE: A country/region-specific AC power cable is included in the shipping container for poweringup an AC power supply. You must order all other power cables separately.NOTE: If a power supply fails, you can replace it while the switch is running by hot-swappinganother power supply. Power supply units are field-replaceable.Power Up Sequence1. Verify that the power source complies with the system input power requirements.2. Connect a power plug to each AC power connector. Make sure that the power cord is secure.38 Installing the Hardware
