Cisco WLC (AIR-WLC2006-K9) Serial Cable

From: Hamzah Khan on 9 Feb 2010 17:03 I've been trying to get access to the CLI on a AIR-WLC2006-K9 WLC I bought a few weeks ago as part of a lab kit, but have been very unsuccessful. I've tried a straight-through serial cable, a null modem serial cable, and two DB-9 to RJ45 serial cables (the type used with most Cisco equipment) with an RJ45 coupler between them, but none of them seem to work (no output on my terminal emulator). I've checked my terminal emulator (minicom) settings multiple times (9600 baud, 8 data bits, 1 stop bit, no parity and no flow control), and I'm sure they are correct anyway since these settings are the same for all other Cisco routers, and it works fine on my 1841 and other routers. I'm just having issues with this WLC. :( Is there a special type of cable I need to use for this WLC? Any clarification truly appreciated! Regards Hamzah

Could this be the problem? Regards Hamzah
From: scott owens on 10 Feb 2010 08:52 The cisco "getting started" documentation on this product will tell you the cabling requirements. Plug it into a network and sniff the traffic - you might see some addresses that you could try to telnet/ssh/web to.

Could this be the problem? Docs say you need a null modem cable, so possibly. Most likely to affect PC end. Cisco say they don't use hardware handshaking. http://www.cisco.com/en/US/prod/collateral/wireless/ps6302/ps8322/ps6308/product_data_sheet0900aecd805aaad6.html Console port: RS-232 (DB-9 male, DTE interface) Cisco 2006 Wireless LAN Controllers http://www.cisco.com/en/US/docs/wireless/controller/release/notes/crn422070..html DB-9-to-DB-9 null modem cable http://www.cisco.com/en/US/products/ps6366/products_configuration_example09186a0080665cdf.shtml * 9600 baud * 8 data bits * 1 stop bit * No parity * No hardware flow control The default username is admin, and the default password is admin. Loads more here. You should be able to find a recipie for a null modem cable on t'interwebby without any trouble.

Same thing can be made from 2 x "RJ-45-to-DB-9 Adapter" - usually marked "Terminal" 1 x "Rolled Cable"- cisco ones usually blue but have seen some black (old ones were black) Same thing can be made from 2 x "RJ-45 to DB-9 Female" - cable 1 x "Rolled Cable" 2 x RJ45 coupler - as you call them. By the way you can also assemble straight through RS-232 cables as follows 2 x "RJ-45-to-DB-9 Adapter" - usually marked "Terminal" 1 x "Straight-through Cable" - normal Ethernet patch lead is fine 2 x "RJ-45 to DB-9 Female" - cable 1 x RJ45 coupler - as you call them. Above works with DB-25 too. See http://www.cisco.com/en/US/products/hw/routers/ps332/products_tech_note09186a0080094ce6.shtml#topic4 If you want you can swap Rolled cable + "terminal" headshell adaptor for Straight Cable + "modem" headshell adaptor modem headshell only available in DB-25 but of course you must be able to make one. You can test your null modem cable and PC by connecting 2 x PCs with it and by running terminal emulator on both, typing should be copied across the cable. I used to have a kit of this plus some gender benders and 9-25 adaptors. Never beaten on any RS-232 device that I encountered that used the standard pinout on DB-9 or DB-25, male or female. |
