A P P E N D I X E Console Cable Pinouts This appendix identifies the pinouts for the serial console cable that connects to the access point’s serial console port.
Appendix E Console Cable Pinouts Overview Overview The access point requires a special serial cable that connects the access point serial console port (RJ-45 connector) to your PC’s COM port (DB-9 connector). This cable can be purchased from Cisco (part number AIR-CONCAB1200) or can be built using the pinouts in this appendix.
A P P E N D I X F Priming Lightweight Access Points Prior to Deployment This section describes an optional procedure designed to prime or stage your lightweight access points in a convenient location rather than after they are installed in possibly difficult to reach locations. This process can be used when a DHCP server is not reachable by your deployed access point and it helps limit potential installation problems to primarily Ethernet and power areas.
Appendix F Priming Lightweight Access Points Prior to Deployment Before deploying your lightweight access points to their final locations, follow these steps to prime your access points: Step 1 In a Layer 2 environment, where the lightweight access points are located on the same subnet as the controller, the access point communicates directly with the controller.
Appendix F Priming Lightweight Access Points Prior to Deployment d. When the lightweight access point associates with the controller, if the access point code version differs from the controller code version, the access point downloads the operating system code from the controller. All the access point LEDs blink simultaneously during the download. Step 6 If the operating system download is successful, the lightweight access point reboots.
