The Cisco Rollover RJ-45 Serial Console Cable for Wireless LAN is a standard nine-pin female DB-9 to RJ-45 serial cable. It can be used between the RJ-45 serial console port on certain Cisco Aironet access points or wireless controllers and the COM port on a computer.
This connection is necessary for setting the access point’s IP address when there is no Dynamic Host Configuration Protocol (DHCP) server in the network. It is also needed when there is no wired connection between the access point and the LAN.
This donation provides a single cable (part number: AIR-CONCAB1200) without any additional equipment.
