Chapter 10: Connecting the Switch CAUTION: Mixing different types of power supplies in the same chassis is not a supported configuration. NOTE: Each power supply must be connected to a dedicated AC power source outlet. Before you begin to connect power to the switch: • Ensure you understand how to prevent ESD damage. See "Prevention of Electrostatic Discharge Damage on J-EX Series Switches" on page 236. • Ensure that you have connected the switch chassis to earth ground. CAUTION: To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, J-EX8200 switches must be adequately grounded before they are connected to power. For installations that require a separate grounding conductor to the chassis, use the protective earthing terminal on the J-EX8200 switch chassis to connect to the earth ground. For instructions on connecting a J-EX8200 switch to ground using a separate grounding conductor, see "Connecting Earth Ground to a J-EX Series Switch" on page 129. A J-EX8200 switch gets additional grounding when you plug the power supply in the switch into a grounded AC power outlet by using the AC jumper cord or the separately orderable AC power cord appropriate for your geographical location. See "AC Power Cord Specifications for a J-EX8200 Switch" on page 76. • Install power supplies in the switch. See "Installing an AC Power Supply in a J-EX8200 Switch" on page 114. Ensure that you have the following parts and tools available to connect power to the switch: • Electrostatic discharge (ESD) grounding strap • AC jumper cords or separately orderable AC power cords appropriate for your geographical location. See "AC Power Cord Specifications for a J-EX8200 Switch" on page 76. WARNING: Ensure that the jumper cords or power cords do not block access to switch components or drape where people can trip on them. To connect AC power to a J-EX8200 switch: 131
