how to connect cisco switch using aux port

> my console port doesnt work for some reason

Are you using the blue DB9 to RJ45 'rollover' console cable?  COM port set to 9600, N,8,1 or 8,N,2 ?

Here's a general cabling guide, but it's hard to send you to specific tutorials when we don't know what switch you have.

I am assuming you have access to the router to configure it, so can you not use telnet or ssh to manage the router? Is there a specific reason you want to be able to manage it out of band?

I would imagine that out-of-band mangement would be a DR contingency for the device in question.
I know thats how I setup all our Cisco gear.

im using cisco 5505 switch, supervisor engine III NFFC, WS-X5530
im using DB9 to RJ45 blue color cable, COM port set to 9600, N,8,1

i bought this device from ebay, the supervisor engine looks working fine, its status LED is in green
im unable to connect to console, thats the issue

i havent configured the switch yet, i dont know what configuration its set

I'm pretty sure you need a cable kit like this one - http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=370149246764  - part# ACS-2500ASYN when included with the switch, or ACS-2500ASYN= when purchased separately.

Refer to http://www.cisco.com/en/US/products/hw/switches/ps679/products_module_installation_guide_chapter09186a008007ecb6.html#xtocid1620215

i have checked with all available baud rates, but it doesnt display anything

console cable i connect with another catalyst 3750 switch, it works good

how about if i physically remove console port in supervisor module, and fix another port from a network card
