2-2 N67xx DUT Power Supply Installation

Replacing a Power Module

Tools required

• T10 Torx driver

• Small flat-blade screwdriver

1 Remove the blower cover:

a Remove the screws from the top and sides of the blower cover.

b Tilt the cover up and slide it out.

2 Use a Torx driver to remove the screws at each end of the power module and

remove it from the frame.

Turn the DUT power supply off and disconnect the power

cable before removing and installing power modules.

Observe all standard electrostatic discharge precautions

before handling electronic components.

Always replace a power module with the same model,

otherwise the DUT power supply cannot be controlled by the

i3070 In-Circuit Test Software.

3 Align the new power module over the pins and push it down onto the

connector.

4 Secure with the screws at each end of the power module. Because the RFI

strips apply upward pressure, continue pushing down on the module until the

screws are tight.

5 Replace the blower cover. Carefully fit the spring clips under the lip of the

power modules.

Replacing Connectors on Old Output Cables

The output cables from some older i3070 systems can be used with the N67xx DUT

power supplies by cutting off the lugs and rewiring them based on the diagrams in

Connecting the Output Cables.

Note that the labels on new output cables are different from the old cables, and the

wiring information in this chapter refer to the new labels. Table 2-1 refers you to the

correct tables for the mapping of old to new labels, depending on the output cable

and channel you are using.
