The WRS-v4 electronics part consist of a single main board (unlike WRS-v3 which consisted of two PCBs). Optionally, user-specific extension board can be connected to the main board. This page is dedicated to the main board of the WRS-v4 and its schematics review.
Review 1: FMC and mSATA connectors will be replaced by SAMTEC and M.2 connectors, respectively, we are waiting for CERN symbols of the following components: SEAF-50-01-L-06-2-RA-GP-TR, SEAM-50-01-L-06-2-RA-GP-TR, MDT420M02001.
Review 1 & 2: While the clocking heart of the WRS-v4 is tested with Clocking FMC, the review of the main board schematics proceeds. When reviewing, keep in mind that the clocking part of the switch is yet to be updated.
