Description

The CAB-CONS-RJ45-DB9 is a Cisco console cable for engineers who need direct, out-of-band access to a router or switch. It is a rollover cable with an RJ45 plug on one end and a DB9 female connector on the other, and it lets a PC or terminal running terminal-emulation software talk to the RJ45 console port on supported Cisco devices.

The cable is 1.8m (6 ft) long and uses rollover wiring, where pins 1 to 8 are reversed end to end (1-8, 2-7, 3-6, 4-5, 5-4, 6-3, 7-2, 8-1). It is a passive cable and needs no power. The DB9 female (DTE) end connects to a serial port on a PC, or to a USB-to-serial adapter if the computer has no serial port.

It suits initial configuration, password recovery, out-of-band management and troubleshooting of Cisco routers and switches that have an RJ45 console port.

Enquire with XS Network Tech for new or used pricing and availability.

A: Use a USB-to-serial adapter on the DB9 female end. The cable itself is passive and needs no power.

A: It is a rollover cable. The pins are reversed end to end (1-8, 2-7, 3-6, 4-5, 5-4, 6-3, 7-2, 8-1), which is the wiring Cisco console ports expect.
