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.1. Position the optic so it is in the correct position. The optic has a key that prevents it from beinginserted incorrectly.2. Insert the optic into the port until it gently snaps into place.Powering Up the SystemAfter you install the chassis with power supplies in a rack, supply power to the C9010.Before Powering UpBefore you supply power to the chassis, Dell Networking recommends that you re-inspect yourequipment rack and chassis. Verify 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. For information about the supported temperature range and othertechnical specification, see Technical Specifications.• There is sufficient airflow around the unit.• All protective covers are in place.• The input circuits are correctly sized for the loads and that you use sufficient over-current protectiondevices.• Each AC power supply unit is correctly installed. A power plug is connected to each AC powerconnector and the power cord is secure.CAUTION: Do not power up the switch if no fan tray is installed.CAUTION: The switch has a high line-voltage requirement of minimum 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 (PSUs) are field-replaceable.Power Up SequenceTo power up the switch:1. Verify that the power source complies with the system input power requirements.2. Energize the remote power source or outlet.3. Toggle the switch on all AC power supplies to the ON (up) position.4. The power supply LEDs show green. If these LEDs do not show green:• Check that you properly installed the unit.• Verify the power source.• If you cannot verify the power supply, power off all modules and replace the unit.5. The fan tray LED shows green (online). You are able to hear the air flowing through the chassis. If thefans are not operating properly or air is not flowing through the chassis:34 Installing the HardwareREGULATORY DRAFT 11-4-14
