Hello,
As i mentioned on this thread: http://community.mellanox.com/thread/1172 I did get into the switch till i set it to be managed by IB instead of ether. Now i cannot connect to it as im having issues using the serial, which i think i may have figured out why. The serial card i bought had some jumpers on it (Startech PEX1S952) They only show two configs for the pins, (windows only and windows+dos). The pins were configured for neither...... SO i'll give it another shot here in a sec.
As for as nmap, i have never had to use it and i dont think im doing something right as it always responds with:
# nmap -v -sn 192.168.2.0/24 -e ib1
Starting Nmap 6.00 ( http://nmap.org ) at 2013-06-21 18:00 EDT
I cannot figure out what source address to use for device ib1, does it even exist?
QUITTING!
ib1 is the ingerface im using for IPoIB. The only DHCP server i have is from my router modded with DDWRT but the IP doesnt show up on the list of connected devices. (ARP table?)
I have tried the reset button. Held it for 3-4 seconds, tried holding it for 8 seconds, and even for 30 seconds, even while it was powered off.
Is there another un-documented way to hardware reset everything to defaults other than from cli?
