By maintaining stable trace impedance across all slot positions, the assembly prevents signal crosstalk during high-frequency backplane clock cycles. The multi-slot backplane architecture facilitates flexible I\/O density scaling without inducing communication latency or requiring firmware flash updates on installed slave cards.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What primary physical function does the DSBB 172B backplane fulfill inside the subrack?\u003c\/p\u003e\n\u003cp\u003eA: The DSBB 172B provides structural mounting slots and backplane trace paths for power distribution and data bus communication between central processing modules and I\/O cards.\u003c\/p\u003e\n\u003cp\u003eQ: Can subrack modules be inserted onto the DSBB 172B backplane while the system is powered?\u003c\/p\u003e\n\u003cp\u003eA: Main power to the backplane assembly must be isolated before installing or removing modules to prevent electrical arcing across edge connectors and data corruption on the backplane bus.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eDisconnect all primary AC\/DC power sources feeding the subrack frame before mounting or servicing the DSBB 172B backplane.\u003c\/li\u003e\n\u003cli\u003eSecure the backplane board flatly into the chassis framework using all designated corner and center grounding screws.\u003c\/li\u003e\n\u003cli\u003eTorque retaining fasteners to standard panel specifications to ensure a low-resistance earth bond with the enclosure frame.\u003c\/li\u003e\n\u003cli\u003eVerify that signal cable shield clamps are attached to the central protective ground bar to suppress external electromagnetic interference.\u003c\/li\u003e\n\u003cli\u003eInspect all connector pins for alignment before locking subrack processor and I\/O modules into their respective slots.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":53221770330421,"sku":"DSBB 172B 3BSE014017R1","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/DSBB172B3BSE014017R1.png?v=1785220453","url":"https:\/\/www.5gplc.com\/products\/abb-dsbb-172b-3bse014017r1-central-units","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
