AF401A UPS management module, pin out for serial ports?

What is pin out for serial ports (RJ45 female connectors) on AF401A management module for HP R5500 UPS? Or, what is pin out for flat cable with RJ45 connectors for serial communication?
I have appropriate RJ45-DB9 adapter.


Best regards, Milovan.

Re: AF401A UPS management module, pin out for serial ports?

Hi,
Thanks for your answer. Well, I have one more question.

Do you know pin out for the cable?

I found that pin out for adapter, 432734-001, supplied with UPS MM is:

RJ45 - DB9, description
1 - 8 CTS
2 - 4
3 - 4
4 - 3 Tx
5 - 2 Rx
6 - 5 GND
7 - 1, 6
8 - 7 RTS

With standard network office or patch cable I wouldn't have crossed Tx and Rx signals (null-modem cable) and communication shouldn't work, I suppose.
With rollover cable (Cisco) GND signals wouldn't match.

Re: AF401A UPS management module, pin out for serial ports?

all you need is the RJ45-DB89 DCE FEMALE adapter, part number AF402A. It will take care of cross-over for TxD and RxD.
The flat cable is just a regular CAT5 NIC cable.
RJ-45 Pin # Color (both sides identical)
Pin 1 White with Orange
Pin 2 Orange
Pin 3 White with Green
Pin 4 Blue
Pin 5 White with Blue
Pin 6 Green
Pin 7 White with Brown
Pin 8 Brown

Connecting, to the configuration port, by UTP cable and 432734-001(AF402A) adapter is working.

Hi Brian,

 

Just wondering if you can provide any more info on the UPS management module pin out information you've posted (I know it's a pretty old post now).

 

Specifically:

  • Where did get the info from?
  • Is there any HP literature that backs this up that you can direct me to?
  • What does CC refer to on pins 1 and 7?
  • What should I expect to see on pin 7 on a low battery event (change in voltage, change in resistance/impedance, change in current)?

 

We're trying to rig something up similar to this -> http://shared.liebert.com/SharedDocuments/Application%20Notes/ap_note_cisco.pdf for performing a clean shutdown of a Cisco CUE module without the need for SSH scripts, but need more information on the "low battery" signal.

 

Any help you can provide would be greatly appreciated.

 

Regards,

 

Mick

Thanks for the 432734-001 pinout, worked out well as a reference for building serial console cable!

(and for Cisco router it was enough to have tx,rx and gnd pins connected).
