Dell part # for MD1000/MD3000 debug/password reset cable?

I've search the forum but can't see this discussed anywhere. I have a dead MD3000 that is out of warranty.  I'd be willing to buy replacement parts EMM, power supply etc but I can't figure out what the problem is. I'm trying to track down the password reset/debug cable, but can't seem to find a part # on Dell's web site.  Does anyone know the pin out of the cable or where I can get one?  

 

Would it work to use an old style PS/2 --> serial converter with a null modem cable, or is the debug/reset cable pinout different?

 

Thanks for any advice.  I'll give Dell a call on Monday, but I was hoping to work on this over the weekend if I can make up a cable myself to do some troubleshooting.

Call Dell Powervault support.

Support on this equipment is lifetime (or at least here in the US it is). When you're out of warranty, they can't send you replacement parts, but they can work with you to see what's going on and also provide part numbers for components that may need replacing.

I'll give tech support a call. 

 

I was able to find the cable by talking to Dell parts dept. Part # is CT109, description is "Service Kit,Assembly,Cable Input/Output,Serial,Modem".  It cost me $10.99 for the cable, $5.99 for shipping and $1.40 sales tax, for a total of $18.38.

 

I did play around with this over the weekend.  I could be wrong, but I don't think this cable is more than a PS/2 to Serial converter, which is what I first thought.  I tried a few different cables & connectors and nothing worked.

We have a similar issue and need the cable, does anyone know the pin-out of this cable or the console interface on the MD3000 or MD3000i arrays or can someone find out using a ohm meter etc. I can make a cable very easily but I can only find this cable for $100 on the internet and cant find it on Dell's website and I really don't want to pay $100 for a cable I should have received when we purchased these arrays a long time ago.

Call Dell spare parts and ask them for a quote for the partnumber (that you found for $100). I can't imagine Dell (spare parts) would charge $100 for that cable.

As for a pin-out; maybe someone else has the equipment to figure that out.

I finally got a cable and it works. If anyone needs the pin-out of the cable here it is below, I know after looking all over the internet I couldn't ever find it.

If looking at the end of the male PS2 end of the cable with the notch at the top and facing the pins and going clockwise starting with the pin at the top right going 1-6, here are the correlations between the DB9 end and the PS2 end. The DB9 end is a female end and has the pins numbered on the end next to each hole.

DB9-------------------PS2

1

2---------------------3 (RXD)

3---------------------4 (TXD)

4---------------------2 (RTS)

5---------------------5,6 (GND)

6

7---------------------2 (RTS)

This was amazing information! Incredibly useful - we would have paid for a cable but had a problem over Memorial Day weekend and had to have one NOW.  This was absolutely correct and worked perfect!!!  Make sure to follow the numbering as described in the post - it's not the "standard" PS/2 pin numbering although the DB-9 was the same.

Thanks so much!!!

Hi,

I tried to make such a cable but it didn't work for me. I have my doubts that I understood the pin numbering correctly.

Would it be possible to obtain a drawing with the numbers?

Here are 2 hits I found with Google in regards to pin-numbering for DB-9 and PS/2:
