Connecting AC Power to an EX8200 Switch
EX8200 switches can be configured with up to six AC power supplies. After you have
installed at least one power supply, you can connect power to 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 EX Series Switches” on page 292.
• 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, 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 EX8200 switch chassis to connect to the earth
ground. For instructions on connecting an EX8200 switch to ground using a separate
grounding conductor, see “Connecting Earth Ground to an EX Series Switch” on page 167.
An EX8200 switch gets additional grounding when you plug the power supply in the
switch into a grounded AC power outlet by using the AC power cord appropriate for
your geographical location. See “AC Power Cord Specifications for an EX8200 Switch”
on page 112.
• Install power supplies in the switch. See “Installing an AC Power Supply in an EX8200
Switch” on page 150.
Ensure that you have the following parts and tools available to connect power to the
switch:
• Electrostatic discharge (ESD) grounding strap
• Power cords appropriate for your geographical location. See “AC Power Cord
Specifications for an EX8200 Switch” on page 112.
