Cisco CBL-RSASR1B-240M6= Rear SFF Cable | Serial Legacy Cable — CBL-RSASR1B-240M6=

Keep legacy systems connected with a Cisco cable designed for a specific rear SFF routing path. The CBL-RSASR1B-240M6= supports controlled cable management where precise fit matters more than generic compatibility. In rack environments, that means fewer improvised adapters, cleaner service access, and a more predictable installation footprint. This cable is suited to teams maintaining Cisco infrastructure that still depends on serial or legacy interconnects. Its purpose-built design helps reduce uncertainty during deployment and replacement, especially when matching existing hardware layouts or preserving established cable runs. For procurement teams, that specificity matters: it supports the exact connection path required without adding unnecessary complexity. When uptime and maintainability are priorities, a direct-fit cable can be the difference between a quick swap and a troubleshooting session. This model is intended for environments where the connection point, routing, and physical fit all need to align with the installed base. Ideal For Replacing an existing Cisco legacy cable in a production rack Connecting PB/PR 2 equipment to a rear SFF 1 interface Maintaining established cable paths in a serviceable chassis layout Supporting spare-parts inventory for Cisco legacy infrastructure Why This Product 1 Purpose-fit Cisco cable versus generic adapter chains 2 Direct connection path for PB/PR 2 to Rear SFF 1 3 Cleaner rack routing than improvised legacy cabling 4 Better match for installed Cisco infrastructure
