Rollover Console Adapter Converts a Straight-Through Ethernet Cable to a Rollover Cable This Cisco serial console rollover adapter connects to the end of any standard RJ45 Ethernet cable and internally rolls the pins to convert the cable from straight through to rollover. This allows you to create a rollover connection between a computer terminal and the RJ45 console port on a Cisco modem, router, firewall, switch or other serial-based device without having to buy new cabling. Color-Coded to Avoid Misidentification That Can Cause Costly Downtime This Cisco console rollover adapter features blue PVC molding. The color-coding allows easy, fast identification in a crowded switch or router and helps prevent the cable from becoming inadvertently disconnected.
