Siemens S30817-Q922-Z301-5 telecommunications hardware (Hicom/HiPath/OpenScape PBX, SDH transmission) PBX Card / Module

The Siemens S30817-Q922-Z301-5 is an SLU8R subscriber line module board for the HiPath 3500 system, presenting eight extension ports from a single slot in the same functional family as the SLA- and SLC-prefixed line modules, though built under the separate S30817 part-number block rather than the more common S30810 block those boards share. The R suffix marks this build’s revision. Every extension wired to a card of this kind depends on it staying healthy, making subscriber line boards among the highest-turnover cards in a HiPath install, and both a failed port and a full shelf call for a matched genuine replacement of the correct block and issue rather than a similarly-named board from a different part-number series. Siemens’s HiPath 3000-series hardware remains in service across many established SME and enterprise sites, and secondary-market spares such as this one are a routine requirement for maintaining or expanding extension capacity.
