Connecting AC Power to an EX6200 Switch
EX6200 switches can be configured with up to four AC power supplies. After you have installed at least one power supply, you can connect power to the switch.
Mixing different types of power supplies (AC and DC or AC power supplies of different wattage) in the same chassis is not supported.
Mixing low-voltage input line and high-voltage input line power feeds in the same chassis is not supported.
Each AC power supply must be connected to a dedicated AC power feed.
Before you begin to connect power to the switch:
Ensure you understand how to prevent ESD damage. See Prevention of Electrostatic Discharge Damage.
Ensure that you have connected the device chassis to earth ground, if required by your site guidelines or installation. A ground connection to the protective earthing terminal is not required for an AC-powered switch. The AC power cords provide adequate grounding when you connect the power supply in the switch to a grounded AC power outlet by using the AC power cord appropriate for your geographical location (see AC Power Cord Specifications for an EX6200 Switch).
For installations that require a separate grounding conductor to the chassis, have a licensed electrician complete this connection before you connect the switch to power. For instructions on connecting earth ground, see Connecting Earth Ground to an EX Series Switch.
Install power supplies in the switch. See Installing an AC Power Supply in an EX6200 Switch.
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 EX6200 Switch.
Ensure that the power cords do not block access to switch components or drape where people can trip on them.
To connect AC power to an EX6200 switch:
- Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
- Ensure that the power supply is fully inserted and secured in the chassis. See Installing an AC Power Supply in an EX6200 Switch.
- Flip the Enable switch on the power supply faceplate to the Standby position.
- Squeeze the two sides of the power cord retainer clip, and insert the L-shaped ends of the clip into the holes in the bracket around the AC appliance inlet on the AC power supply faceplate. See Figure 1 or Figure 2.
- Locate the power cord or cords shipped with the switch; the cords have plugs appropriate for your geographical location.
- Insert the coupler end of the power cord into the AC appliance
inlet on the AC power supply faceplate.
If the optional power cord tray is installed, thread the power cord through the power cord tray.
- Push the cord (close to the coupler end) into the slot in the adjustment nut of the power cord retainer. Rotate the nut until it is tight against the base of the coupler and the slot in the nut is turned 90° from the top of the switch. See Figure 3 or Figure 4.
- Repeat Steps 4 through 7 if you are connecting a power cord to the second appliance inlet on the 5000 W AC power supply.
- If the AC power source outlet has a power switch, set it to the OFF (0) position.
- Insert the power cord plug into an AC power source outlet.
- Repeat Steps 9 and 10 if you are connecting a power cord to the second appliance inlet on the 5000 W AC power supply.
- If the AC power source outlet has a power switch, set it to the ON (|) position.
- Verify that the INPUT OK LED on the power supply faceplate is lit and is on steadily.
- Repeat Steps 2 through 13 for the remaining power supplies.
