4.2 Hot Attachment of AC Power Supply
 Unpack the power supply carefully. Inspect for any damage. If any damage is observed, do not use the power supply and
call 949-250-6510 to report the damage immediately and request a replacement unit.
 Align the guide rails on the chassis with the rails on the bottom of the power supply; Slide the power supply in, ensuring that
the power supply is seated firmly against the backplane and tighten the thumb screws securely with a screwdriver.
 Plug the AC cord to the back of the power supply.
 Plug the AC cord to the AC wall outlet.
 Watch and listen to the fan in the rear of the power supply to ensure it is powered.
 Save the packing material of the new power supply for return shipment of the faulty power supply or for future reuse.
4.3 Hot Removal of DC Power Supply
 Determine which power supply is faulty by observing the status LEDs on the back of the power supply (8227-2 only) or viewing
the status using the iConverter NMM2 and network management software. When viewing the LEDs on the NMM2, PSx
LED OFF indicates power supply “x” is not present, PSx LED blinking indicates power supply “x” is installed but not powered
and PSx ON indicates power supply “x” is powered. When viewing the LED on the back of the power supply, a yellow LED
indicates the power supply is installed but not powered and both fans are ON. A blinking yellow LED indicates the power
supply is installed but not powered and only one fan or neither fan is ON. A green LED indicates the power supply is installed
and powered with both fans ON.
 Power Supply 1 (PS1) refers to the power supply on the right (as viewed from the front). Power Supply 2 (PS2) refers to the
power supply on the left.
 Once you determine that your DC source is connected properly, and the power supply LED is still not ON, determine which
is the failing power supply unit and proceed to the next step.
 Locate the DC circuit breaker, and switch the circuit breaker to the OFF position.
 Remove the DC power cables of the faulty power supply from the power supply unit.
 Using a screwdriver, loosen the 2 thumb screws securing the power supply to the main chassis (refer to Figure 5).
 Remove the failing power supply.
4.4 Hot Attachment of DC Power Supply
 Unpack the power supply carefully. Inspect for any damage. If any damage is observed, do not use the power supply and call
949-250-6510 to report the damage immediately and request a replacement unit.
 Align the guide rails on the chassis with the rails on the bottom of the power supply; slide in the power supply ensuring that
the power supply is seated firmly against the backplane and tighten the thumb screws securely with a screwdriver.
 Locate the DC circuit breaker and make sure that the switch is in the OFF position.
 Reconnect the DC power source to the power supply.
 Locate the DC circuit breaker and switch the circuit breaker to the ON position.
 Watch and listen to the fan in the rear of the power supply to ensure it is powered.
 Save the packing material of the new power supply for return shipment of the faulty power supply or for future reuse.
