Hello all,
We have a PXIe-1048 chassis, without the timing and synchronization upgrade, and the PXIe-1084 User Manual just doesn't do a good enough job of documenting the chassis backplane DIP switches. There is inconsistency in the way that it is shown and described in the document and I'd like to expect better from such a manual.
You see, Figure 1-1 Front View of the PXIe Chassis, shows the location of the switch in the proper place, showing them with an up-down orientation as seen below:
This figure matches the PXIe-1084 we have on hand. Here it is, zoomed to 600%:
Now, the section of the manual on the DIP switches describes them completely differently than the detailed view:
Everything, and I mean everything, in this section describes the operation in a sideways configuration. First/second from the bottom, left position, right position, etc. These descriptors are useless when the switch is, once again, not oriented in this manner. Now you might say, "u/he_schutz_he_scores, isn't it an easy enough leap of reasoning to say that usually Up is the "On" position for vertically-oriented switches, so just rotate all the instructions 90 degrees clockwise?" I say, "No, the documentation ought to match the hardware the company makes."
Therefore I ask two things:
1. Given the true orientation of the DIP switches, can we confirm that the LEFT switch is DIP Switch #1 to control Fan Speed, the RIGHT switch is DIP Switch #2 to control chassis Inhibit Mode, and that UP is ON?
2. Please update the manual to actually show the hardware the way it exists.
Thank You.

Hi its been nearly 3 weeks, anyone from NI care to comment on this?

Typically, the SMD DIP switches have markings on the switch number and which position is ON.
And the manual also shows markings ON, 1 and 2, does the actual switch on the PCB contain these marking to match?

Here's what the PCB and component have:

Well, that is definitely not the same shown in the manual, I can relate your pain.
I would rather experiment with the positions to find out the right combination.

Hello he_schutz_he_scores,
The right orientation of the DIP switches is to rotate the picture shown in the manual to 90 degrees counterclockwise.
With that being said, the DIP switches will look like this physically:
The DIP switches should be enumerated and with the ON sign on it.
