CradlePoint rollover adapter for RJ45, blue — RJ45 to RJ45 console cable

The CradlePoint rollover adapter for RJ45 in blue is a passive wiring adapter that reverses the pinout of a standard RJ45 Ethernet cable to enable console access and device management. It converts a regular Ethernet lead into a rollover cable allowing connection between networking equipment and terminal ports for configuration, maintenance and troubleshooting. The adapter is compact, color-coded blue for easy identification and intended for use with standard RJ45 console ports and serial console adapters.

Advantages

This rollover adapter provides a simple, tool-free way to reverse RJ45 wiring without modifying existing cables. It is passive, requires no power, and has been successfully tested up to 100 m with selected Juniper and Cisco devices when used in appropriate installations. The blue color makes it easy to identify among other leads, and its RJ45 male-to-female form factor supports inline use between an Ethernet cable and a console port.

Suitable for

• Converting a standard RJ45 Ethernet cable to a rollover/console cable for device configuration
• Temporary or lab connections for networking equipment console access
• Maintenance and troubleshooting tasks that require serial console access via RJ45
• Inline use where a quick wiring reversal is needed without creating new cables

Key specifications

• Connector type: RJ45 male to RJ45 female
• Function: Wiring reversal (rollover) for console access
• Color: Blue for visual identification
• Device type: Passive adapter, no power required
• Test information: Successfully tested up to 100 m with certain Juniper and Cisco products; recommended to verify runs over 50 m in individual installations

How to use

Plug the RJ45 male end of the adapter into the device or console port that accepts an RJ45 rollover connection, then connect a standard RJ45 Ethernet cable to the female end. Verify the pinout and compatibility before use: many Juniper products use straight-through RJ45 cables and may not require a rollover adapter. Confirm the console pinout of both connected devices and, if necessary, test the connection at short length before deploying longer runs.

Recommendations

Check the pinout of both endpoints before use and verify compatibility with the target device. For runs over 50 m, validate signal integrity in your specific installation; CradlePoint notes successful tests up to 100 m with selected equipment but does not recommend unquestioned long runs. Use the adapter for temporary or diagnostic connections and keep a labeled spare for maintenance tasks.
