SG300 / SG500 console connection doesn't work.

[etched.headplate]

Hello All,

I am failing to connect to the console of SG300 and SG500.

So far I've tried using few different cables:

- 9f/9f null modem cable - exactly this one: http://www.delock.com/produkte/G_84169/merkmale.html?setLanguage=en

- Cisco blue cable with RJ45 to RS232 adapter

- RS232 cable with USB adapter

In terms of software and configuration, I've tried:

- putty

- realterm

- every possible baud (9600, 115200, etc.) with default 8/1/none options

I'm running out of ideas. Perhaps I should use a different cable?

Any suggestions?

Thank you!

Sounds like you are trying all the right things.

Presumably you have hit the enter/return key a few times once the console is up?

Had this switch worked previously in terms of the console?

Thanks

Yes.. tried that, no success.

I'm trying 3 different switches and 3 different computers, so this must be the cable.

Does anyone know what is the right console cable for sg300 & sg500?

9-pin F / 9-pin F null modem seems to be not working.

Thanks!

Hi there,

did your tried direct connection ,

9f/9f null modem cable > PC with COM port. 

some USB converters are not working properly with different electric signals. 

also,

try, 9f/9f null modem cable > USB converter > USB port PC

try this with below settings.

Bits per sec    :  9600 
Data bits       :     8 
Parity          :  none 
Stop bits       :     1 
Flow control    :  none

Straight serial cable with gender changer att the computer end worked for me! Strange but true.
