W cable A5191-63001 wiring

Hello all!! I have several rp5470 (L3000) and rp7400 (N4000) servers, and need desperately to get the wiring diagram for the A5191-63001 "W" cable! Without this, I'm stuck... I have found some links here in this forum, but they are dead. Somebody has this wiring diagram so I can build it? Buy it is very dificult for me. And, if somebody knows, what settings Hyperterminal for XP is needed to establish comunications with the GSP? Also... :-) a way to reset the GSP to its default settings, because the servers are used and Don't know how they are configured. Well, excuse me so many questions for the first time. Best regards, and thank you in advance.

Are you sure? I know nothing, but I thought
that the primary serial port appeared on the
normal pins, so that a plain-old serial cable
would work, unless you wanted to use the
modem port, or something else exotic. (Or
that may have been a Sun multi-serial port.)
Have you looked at pins 2 and 3 (and 7)?

> [...] links here in this forum [...]

Have you asked Google?

> [...] what settings [...]

I still know nothing, but I'd start with
9600b/s, 8 bits (1 stop bit), no parity.

> [...] a way to reset [...]

Have you looked at the manuals for these
systems?

Re: W cable A5191-63001 wiring

HI Finis,

Details of W cable:

Photo of Console cabel (W Cable):
http://partsurfer.hp.com/ShowPhoto.aspx?partnumber=A5191-63001

(Computer) DB-25 pin (M) - will connect to the Core IO card(25Pin (F) of the Server

UPS - DB-9 (M) for UPS connection
Remote - DB-9 (M) for- Modem Connection
Console - DB-9 (M) for-local Console connection (GSP/HPUX Console)


Hyperterminal/Emulation:
The software emulates console output as it would appear on an ASCII terminal screen and displays it on a console device screen.

2. To ensure the emulation software is correctly configured, verify the following:

a. Verify that the communication settings are configured as follows:
â ¢ 8/none (parity)
â ¢ 9600 baud
â ¢ None (receive)
â ¢ None (transmit)
b. Verify that the terminal type is configured appropriately. Supported terminal types are as follows:
â ¢ hpterm
â ¢ vt100
â ¢ vt100+
â ¢ vt-utf8
IMPORTANT: Do not use hpterm and vt100 terminal types at the same time.

There are many different emulation software applications. Consult the help section of your emulation software application for instructions on how to configure the software options.

3. Use rear View picture determine the required connection components and the ports used to connect the server to the console device.

4. Connect the cables.
a. Connect the DB-9 end of the RS-232 serial port female-to-female cable to the console RS-232 serial port.
b. Connect the other end of the DB-9 female-to-female cable to the console device.

5. Start the emulation software on the console device.

6. Log in to the GSP

Hope this helps.

Re: W cable A5191-63001 wiring

Steven, Surendar; Thank you a lot for the info!! I still need the wiring diagram, that is, how are each of the DB25 pins connected to the 3 DB9 pins? I need the 3 DB9 working, because I need the UPS be commanded by the server, also the modem (remote) function.
With regards to factory defaults of the the GSP, the only way is with console access. I will try removing the batery, hope this don't clear the firmware...
HP didn't saved the internal wiring diagram for the A5191-63001 W cable.
If somebody has that diagram to pass it to me, I'll very gratefull (sorry for my ugly english). Best regards!

Re: W cable A5191-63001 wiring

Something to note is that for the rp7400 server you do not require the W cable as there are (3) DB9 ports built on the Core I/O board.

In order to reset the GSP to its default login/password push and hold the GSP reset button for 5 seconds and monitor the console. A prompt will appear to reset the login info.

The default login are cleared values. That is press twice to login. Press CTRL+b to access the GSP prompt.

From the GSP prompt issue the DC command to reset all values to the factory defaults.

Re: W cable A5191-63001 wiring

Hello Bob! Yes, I've seen the DB9 console port at the rp7400, thanks!
I've reset the GSP with that button days ago, but still couldn't login. So, I removed the battery from the GSP... may be something was screwed (if so, no matter, I've 3 more to take spares)? After that, the server started blinking an red led in front. The servers are at an office far away from I'm now, so tomorrow I'll try to connect to the GSP with the suggestions from the another guys.
One question: the server can be started from one SCSI CD drive, in order to install Debian? And... can be installed a PCI video card from another brand? (it's not the one that HP offers for this server). Best regards and thank you again.

Re: W cable A5191-63001 wiring

The L3000 does have an internal DVD/CDROM, but the N4000 does not. An external device would have to be used.

In regards to the video card, that will depend on what Debian supports on this hardware. The PCI slots are standard, but the bus architecture behind them (what HP calls WSIO) is not.

Re: W cable A5191-63001 wiring

Zygmunt, I am very very grateful to you for the wiring diagram of the W cable for the HP9000 server. Now I can try to connect an UPS.
May be you know what are the serial port settings for this machines: The rp5470 (aka L3000) and rp7400 (N4000)? If not, no problem, they can be found somewhere for sure.
Regards!!
Torsten.

Re: W cable A5191-63001 wiring

This depends on the type of UPS and the management software.

Hope this helps!

Re: W cable A5191-63001 wiring

Hello Torsten! OK, but could be that there is some default program already part of HPUX that manages the UPS? If so, may be only manages some range of bauds, etc; and this must be supported by the UPS selected. That is, when I ask the vendor for a model, I need to say him: "this UPS can comunicate at for example 1200/8/n/1/x flow control??". Well, the truth is that I'm not going to buy a new UPS for this machines, because is absolutely out of my budget (the big ones, according to the power consumed by a N4000, are very expensive!), but at my working place, there is one big LUNAR that could be gave it to me, and would be useful to know if can be "understanded by HPUX". Hope you can understand me too... :-). Thanks!
Torsten.

Re: W cable A5191-63001 wiring

You need a UPS that is powerful enough for your server (of course) and it must have management software for HP-UX.

There is default software (ups_mond), but it works for certain models only!

Even different HP UPS models need different management software.

Hope this helps!
Regards
Torsten.

Re: W cable A5191-63001 wiring

Torsten, thank you again for transmitting your valuable knowledge. So, I need to see if the big Lunar UPS has HP-UX soft (I think it has not...). Then, I could set a second PC that manages the UPS, and send the shutdown signal to the HP9000s in case of power is down. Suggestions about this? Regards!
Torsten.
Acclaimed Contributor

Re: W cable A5191-63001 wiring

Even if the HP-UX server is a client for another UPS management server, you need a piece of software that is "listening" to the master and starts the shutdown.

Hope this helps!
Regards
Torsten.

Re: W cable A5191-63001 wiring

Yes Torsten, the second machine would be listening to the UPS, but it is an old Acer Windows server, so more easy to find soft to do that. I need an UPS, because each lot of chemical molecular simulations could take hours or days of calculations, and if shut down not gracefully, work and energy spent would be lost.

Re: W cable A5191-63001 wiring

BTW, I found used HP UPS (e.g. PowerTrust II) sold for around 70 EURO on different places in the world. The question is, if the batteries are still good enough ...


IMHO your problem is how to initiate the server shutdown in case of power loss.

Hope this helps!
Regards
Torsten.

Re: W cable A5191-63001 wiring

UPS standards (something that would allow HP-UX or a PC to perform a group shutdown) simply do not exist. The ups_mond program works with the (very old) Sola systems (Power Trust). The newer UPS models from Compaq (the R3000, R6000, etc) are completely incompatible with ups_mond and came with software called Power Manager. Alas, it appears that HP has obsoleted Power Manager for HP-UX:

http://h18004.www1.hp.com/products/servers/proliantstorage/power-protection/software/power-manager/index.html

and points to a very old 3rd party product called LanSafe III. Unfortunately, it is fairly clunky and seemingly incomplete without a shred of documentation. I did locate the UPS's current owner (Eaton) and found LanSafe 6 which comes in several OS versions, but with the same lack of documentation as LS3. However, it appears that you can install this on 11.11 (and higher) and it will issue a shutdown (halt) before the batteries run out:

http://powerquality.eaton.com/portugal/support/software-drivers/default.asp

The same software, when installed on other HP-UX systems can be configured as a group and they will be commanded by the controller system to also shutdown at the same time. This is for all the machines running off the same UPS, usually in the same rack.

The Compaq-branded Eaton units use a serial straight through extension cable, that is, a male+female cable. Although Eaton supplies a LAN card as an option, I haven't been able to test this connection with LanSafe6. Eaton also provides a PC-based information program called LanSafe WebView (but listed as "legacy"). It does work with a HP-UX based system. Note that for an L-class and N4000, you must use the Remote port (not the UPS). Apparently the HP desing for the UPS port is incompatible with the Eaton UPS models.

As far I can tell, UPS support for HP-UX appears to have been dropped early in 2010. Probably the thinking was that these big servers would always be in a data center with a generator.

Note that you can never predict the length of time for a future power failure. It may be seconds or hours...the batteries will only last long enough to ride through a short (a few minutes depending on the load). So your lengthy calculation programs need a restart mechanism that detects standard kill signals, saves intermediate results and gracefully shuts down before HP-UX finishes shutdown and halts.

> old Power Trust batteries...

The Sola/PowerTrust and Eaton units all use sealed lead acid batteries which have a finite shelf life as well as active service life. Batteries older than 3-5 years must be recycled. While they may read 12 volts DC, the UPS may run for only a few seconds before the voltage drops below a useable level. Modern UPS (*NOT* the old Power Trust) circuits will evaluate the battery health and provide battery warnings so they can be replaced before you need them. I have seen some systems with 8-9 year old batteries but never saw a power failure. When there is one, the batteries will be useless.

Re: W cable A5191-63001 wiring

Bill, Torsten; your data was very useful; thank you very much again!! Sorry for the delay, I was ill. Well, I see that an UPS is not going to work automatically with HP-UX. That brands/models availabe are unreachable because of budget limitations; as they are too heavy (shipment cost) to buy it at ebay, for example. Maybe the best choice is keep pinging to some small device as an old router (or an old 486 PC) not connected to the UPS (any what I can get), and when response fails, means the line is down, some script alarms, I access remotely the server and shut it down manually. What do you think? Could work?
Regards!

Re: W cable A5191-63001 wiring

> ping an old router

Yeah, that would probably work as long as you have enough battery power to keep the HP-UX box going until it shuts down.

Note that you may be able to get a cheap UPS without the batteries (make sure the battery clips and tray come with the empty box). UPS units on eBay probably have dead or almost dead batteries anyway.

Re: W cable A5191-63001 wiring

Hi Bill. Yes, this only would work if I've a fast response... With regard the UPS, may be I've not said in this thread that I'm at Argentina, so the shipment cost, even without the batteries, may be too high. I was thinking that some guy with electronics knowledge could design a small device that detects the falls on power, and sends via RS232 a simple signal, using a microcontroller. At the machine side, a simple C routine could be listening, and in the event detected, send the shutdown signal. This could finish all the hassle with UPSs and softwares that can't understand each other. What do you think? Could be good bussiness! :-) Regards.

Re: W cable A5191-63001 wiring

Have you measured the time required to shutdown your server? It will require at least 20 to 200 seconds to shutdown your server. So unless you can find some sort of UPS to keep power supplied for a couple of minutes, your server instantly halts when power is removed. Nothing in memory is saved.

So back to the original solution: rewrite your application with checkpoints, saving intermediate results in a file every few seconds. Then if power disappears, you reboot and tell your program to start at the last checkpoint.

Re: W cable A5191-63001 wiring

Bill, you are right, the time required to shut down is too long; so the best is save at disk every some second or minutes... Shame that UPSs technologies are so incompatible between them. Could HP-UX get corrupted (as to need reinstall) if server is shut down not gracefully? Cheers.

Re: W cable A5191-63001 wiring

Any power fail has the potential to corrupt a filesystem. That's why you have a tape backup or a dd (drd if you are running 11.23 or later) copy of your boot disk on another disk.
