    I have a legacy 4 wire dish with a SWM-8 in the attic. I currently have an HR24. 4 wires from the dish go into the SWM-8 and then the output goes directly into the HR24. I have the power inserter going into the SWM-8 as well. On the HR54, the wiring diagrams show that I need to use the splitter to split out the power pass? I don't use the splitter on the HR24 now. I am 100% sure on that since I hooked it up. Is the no power pass splitter just something for the HR54?

    The HR54 can power a SWM LNB on its own But if you have separate power already then you can connect it anywhere

    Wait... lol... so my current setup is I have the 4 wire legacy LNB going into a SWM8 and I have the PI hooked up. The SWM-8 output to the HR24 does NOT have the power pass splitter on it.

    Do I need to remove the PI and/or add the splitter if I want to switch to the HR54? I will have NO other boxes on it except the HR54.

    I'm not sure, but I don't think the HR54 will power a swm switch which requires 29 volts. Any installers here know for certain?

    54 will not power swim mod. Leave PI in place.

    Correct ...

    Simply connect the 29v PI to the SWM 1/PWR coax line of the SWM-8 multiswitch to power it. And the HR54 to the "to IRD" port of the PI which blocks its internal 21v PI, but passes the SWiM/MoCA signals to and from the HR54.

    A SWM switch no. But it can power a SWM LNB

    So an HR54,and I assume an HS17 and H44, only puts out 21 volts, not 29.

    Yep ...

    As they were not designed to power an external multiswitch.

    Only SWiM LNBs that use less power at a lower voltage ...

    Ok, so same exact hookup as the HR24. No splitter needed. Thanks.

    I don't think the voltage matters - a SWM16 (and I presume a DSWM30, which I know works on 24 volts because that's what is feeding mine) are able to handle a wide range of input voltage and will work perfectly well on 21 volts or even less. But they need enough watts, and if the HR54 doesn't make enough power available it won't work even if it were output at 29 volts.

    Since the DSWM30 requires less power than a SWM16, I wouldn't be surprised if the HR54 was able to power it. But it might not do so reliably and/or shorten the life of the HR54's power supply, so I don't know why you would.

    Isn't HW specs of HR54 and SWiM-8/16 device published ? DC voltage range and max current ?
    that's typical parameters of DC sources and loads and must be known

    No, why would they when Directv specifies the devices they can be used with? You only publish specs when you expect something you didn't design/control to be used with it.

    If you haven't figured it out by now, assuming your power PI is plugged directly into the SWM, unplug the HR-24, plug in the HR54, done.
