Re: netra LOM serial port
AFAIK the LOM isn't OS dependent.. it's simply a small cpu that sits between Serial A and the console "port" on the motherboard. When you send the magic sequence (usually #. but this can be reconfigured) Serial A switches from the system console to the LOM processor. If you can get hold of a standard cisco (rolled) console cable and a matching DB9 convertor (make sure it's DTE not DCE) then you shouldn't have a problem. I would guess that your cabling is wrong as you should at least get the system console output. My Netra T1/105 is running fine with Woody and the LOM is very useful for the rare occasion I need to power cycle it remotely. I usually leave it sat at the LOM> prompt and not the console as the terminal server it's connected to isn't break safe.. the LOM will catch the break instead of it halting the box. Hope this helps, Rich. On Sun, 29 May 2005, Martin Habets wrote: > The last time I tried (almost 2 years ago) the LOM serial port was > not supported by Linux.

Re: netra LOM serial port
The last time I tried (almost 2 years ago) the LOM serial port was not supported by Linux. Actually, LOM was not supported at all by Linux (I'd be interested to hear if it is now). I used the regular serial port. If the machine is set up to do a network boot it does not always respond to a break: you may need many break attempts before one succeeds.

You can find the pinout for the cables on page 38 of http://www.sun.com/products-n-solutions/hardware/docs/pdf/806-5980-10.pdf Richard On Tue, 2005-05-03 at 20:00 -0500, Colleen Hatfield wrote: > On 5/3/05, Tom Vier <[EMAIL PROTECTED]> wrote: > > I got a rack mount netra off of ebay recently, but i can't seem to get into > > the firmware console.

I use the ones that came with my Cisco gear, but they're easy enough to make if you don't have one lying around. - Colleen
netra LOM serial port
I got a rack mount netra off of ebay recently, but i can't seem to get into the firmware console. I have an rj-45 <-> db-9 adapter and a db9<->db9 null modem cable. I'm using 9600 8n1, and i've tried w/ and w/o flow ctrl. I tried sending break and hitting enter and it doesn't respond, even when it's powered up. I've also tried a attaching to the rj45<->db9 a cable with and w/o a null modem adapter.
