Hi Experts,

I have sunfire v100 But I am not able to get the lom prompt from the hyperterminal,
I have a DB9 female adapter connected to the com port on my laptop and a ethernet cable is connected to the com port ( i.e. DB9 ) and the same cable is connected to the SunFire v100 A LOM port on sunfire v100.
Can some one guide me on how to do this as there is no OS installed on this server. How to install the OS in this scenario ?

Thanks a lot

Where did you get the RJ-45 to DB-9 adapter? Is it the one that is supposed to ship with the V100? If not, that
would be my first suspicion, that the adapter does not provide the correct signals. See the V100 installation guide
at for details of the pin outs.

After that, I would check the port settings. Are you sure you are connecting through the correct port? The serial
port settings should be 9600 baud, no parity, 1 stop bit, 8 data bits. Is that what you have?

After that, try unplugging and re-plugging in the v100, that should reset the LOM. Look for output in the
hyperterm. Then hit the return key a couple of times and see if you get a prompt.

No I already had RJ 45 with me i used that and I purchased the DB 9 Female adpter from EBAY, those were not shipped with the V100. The serial port setting are correct what you have mentioned in the answer. I will try again today by using the inputs you have provided and will reply back tonight.

Thanks blu :-)

Okay. At this point, I would be most specious of the pinouts of the adapter.

What does it means by pinouts of the adapter ? OR Will I have to purchase the genunine sun DB adapter? which One it should be mail OR female ? Right now I have female adapter DB 9.

Thanks for you help.

Well, if you had the adapter that came with the system, then we wouldn't have to be suspicious. As far as I know, there is no standard for connecting DB-9 adapters by RJ-11 cable, so it is very possible that the pinouts are different. The link
I gave you above has a diagram of the actual pinouts needed. You should verify that the pinouts are the same on the adapter you have.

I have RJ - 45 ethernet cable and after observing the DB 9 adapter I found that one of the pin out of 8 pins is broken ( Only 7 pins are visible ) because as I counted the no of pins on the RJ-45 those are 8 pins and so should be on the DB 9 adapter. And on the serial  connector on the laptop there are 9 pins. Please correct me if I am wrong.

Thank You for taking out time to answer my question.

It is hard to say if that is a problem. There are only 7 pins used on the Sun adapter. Sometimes an adapter will leave
off missing pins, so that may be normal. Pins 1 and 9 are unused, so if the missing pins are those, you should still
be okay.
