Rollover Console Cable Converts a Straight-Through Ethernet Cable to a Rollover Cable. This Cisco console rollover cable 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. Provides Unrestricted Access to Adjacent Ports. In contrast to short M/F plugs that block adjacent RJ45 ports when they are connected this RJ45 rollover console cable for Cisco products is recommended for console servers and other devices where ports tend to be tightly packed together. The narrow RJ45 male end connects securely to the device while leaving adjacent ports accessible. Color-Coded to Avoid Misidentification That Can Cause Costly Downtime. This 12.7 cm Cisco console rollover adapter features a blue PVC jacket and fully molded blue ends.
