Connecting the Output Cables
These instructions are for a system being configured for the first time.
1 Wire the connector to the output cable.
For N6751 and N6746, the cable must be secured with a strain relief.
2 Connect the output cables from the DUT power supply to the ASRU card. Refer
to the procedure for DUT power supply model you are installing.
– Connecting Output Cables for N6751
– Connecting Output Cables for N6752
– Connecting Output Cables for N6773
– Connecting Output Cables for N6746

When adding a supply, the configuration of existing supplies
may prevent you from following all of these procedures.
Do not reconfigure existing supplies. Reconfiguring existing
supplies is likely to cause previously developed board tests to
fail.

Connecting Output Cables for N6751
The DUT power supply connections are J4 and J9 on the ASRU Card. The ASRU
Card end of the cable can be either a 34-pin connector or a 20-pin connector.
The 34-pin connector is for ASRU channels 1–4, and the 20-pin connector is for
channels 5–6. Refer to the Connector Wiring Charts and connect the output cables
as described in Connecting to the ASRU Card.
