Installing the power supply

Installing

To install the EC 11 power supply, follow these steps.

Step Action

1 Verify that the circuit breaker on the front plate of the

power supply is off. Zero represents off.

2 Align the power supply with the far left slots, ensuring

that the locklatches are open.

3 Ensure that the rear connector is aligned with the

backplane connector, then gently slide the power

supply all the way into the module.

4 Close the locklatches.

5 Ensure that the power supplies in both the EC 11 and

the Option 11 switch are connected to the same

building ground.

6 Connect the power connectors as follows:

a. Attach the AC cord to the bottom of the power

supply and plug it into an AC outlet.

b. Attach the battery connector on the bottom of the

power supply to an external NTAK75 or NTAK76

battery backup unit (if required).

7 Switch on the breaker on the power supply.

Both front panel LED indicators should light if the

backup battery is installed. Only the DC LED

indicator should light if the backup battery is not

installed.

8 Switch the power supply off if you are installing

additional cards in the EC 11.
