Connecting EX9214 to AC power
NOTE:
Do not mix AC and DC power supplies in the same switch.
NOTE:
This procedure requires at least two AC nominal 220 VAC 20 amp (A) power cords. See the AC Power
Cord Specifications for the EX9214 Switches to identify the power cord with the type of plug appropriate for
your geographical location.
1. Attach an ESD wrist strap to your bare wrist, and connect the strap to the ESD points on the chassis.
2. On the power supply, rotate the metal cover away from the input mode switch to expose the switch.
3. Move the input mode switch to position 0 for one feed or position 1 for two feeds.
4. Set the power switch of the AC power supply and the AC input switch above the power supply to the OFF (0) position
5. Plug the power cord into the corresponding appliance inlet located in the chassis directly above the power supply. This
is the recommended receptacle when using the power supply in one-feed mode. If you are using the power supply in
two-feed mode, plug the second power cord into the receptacle on the power supply.
NOTE:
Each power supply must be connected to a dedicated AC power feed and a dedicated customer site
circuit breaker.
6. Set the power switch of the AC power source outlet to the OFF (0) position.
7. Insert the power cord plug into the power source outlet and switch on the dedicated customer site circuit breaker.
8. Set the power switch of the AC power source outlet to the ON (|) position.
9. Set the AC input switch above the power supply to the ON (|) position. This is the only switch you have to turn on if
you are using the power supply in one-feed mode. If using the power supply in two-feed mode, set the power switch
on the power supply also to the ON (|) position. Remember to turn on both switches when operating the power supply
in two-feed mode.
10. Verify that the AC OK, AC2 OK (two-feed mode only), and the DC OK LEDs are on and steadily lit green, and the PS
FAIL LED is not lit.
