Not looking good here today. My second cabinet is not responding, yet the power is on and I have blinking lights.

From the programming terminal, screen F page 1, all is normal. Page 2, cabinet 2, it does not list any of the card descriptions, yet it does have all of the station programming for the cards.

What is the best way to determine if the communication between the two cabinets is impaired? How can I 'cold-boot' the system to see if that clears things up?

Any other thoughts on why the slave is not being 'seen'?

Do you have a I/O MDF hooked up to second cabinet. You can pull Fiber card and is if cabinet works as stand alone, by hooking up laptop direct to second cabinet.

Good Luck!!

Have you checked the options on the main cabinet, make sure 432 is in the options.

Okay, been away trying to 'recover' from this failure. This was a working installation, so I would not think the option for the second cabinet would have anything to do, but I shall check later.

What I have done at this point is to physically move all of the extentions from the slave and reporgram them into the master. Yes, a long task, but at least it all works now (and to think we had that much excess capacity).

I will need you guys to assist with troublshooting the hardware. My 'user manual' does not seem to cover the troubleshooting portion.

Let's start with connecting to the slave. Is the RJ45 jack on the CPU card the serial interface? If so, I will connect to that and I assume log in as I would from the RS232 port on the master. If I need to do anything different, please advise.

Once I'm connected, what can I 'see' and test through the menus? How can I test the communication between the master and slave? Where do I find some alarm indicators?

What would be some good steps to 'reset' the hardware in the slave, without resetting the configuration?

Thanks guys,
MF

That RJ-45 jack if its an ACPU card is for programming the flash memory chips if the card has them.
The programming ports come out of the cabinet at the bottom right corner on a 36 pin amphenol.I think in the US you guys used what they called an MDF which pins them out for you.
The reason you see the extensions on page 2 of the F screen is that the programming for the system is in cabinet 1 as well but it doesn't see the cards anymore.The cabinetsa are of course tied together through the fibre mux crads and the fibre cable.If you have the advanced fibre mux cards they do have the capability of hooking up a third cabinet so you might be able to try that and see if the port on the main cabinet fibre mux is bad.

Are there any diognostic screens within this system to assist me in figuring out WTF is going on here?
Posted By: nonameyet Re: Slave Communication Down. Now What? - 03/16/05 02:42 PM
Dumb question..

Have You tried Resetting the Complete System?

Shut down Cab 1 and the shut down cab 2

Turn on cab 1 , wait untill it working, then turn on cab 2 , if the system ' see's ' the second CPU, it will Reset again by-itself.


also, You ' Could ' try swapping CPU's NOTE:


Be real careful when doing this, There are Dip-Switches on the CPU's to tell the system which is Number 1 and which is Number 2


There are 8 led's on the CPU's LOOK at them, Notice the different Leds that are lite, and which ones are Blinking?

I'm going from memory here... I might be Wrong. BUT, Cpu 1 will have the Top led Blinking, and Cpu 2 will have the Top led solid ON and the 2nd from the Top Blinking

the rest of the Leds on BOTH CPU's should be On.


Also, Somebody else here did ask if You still have Your 432 Option?


If It's Gone(which, I have seen happen) YOU will Not be able to see the cards in the second cabinet.


Possible problem : You blew a Power Supply..

These are also Interchangeable...NOTE: the PS on the left side of the cabinet Plugs into the one on the Right ... ALWAYS...
Posted By: MagnusFox Re: Slave Communication Down. Now What? - 03/17/05 08:03 AM
Must of this will be in response to nonameyet's post above.

I'm not sure how to 'check the 432 option'. On the main screen my system options show: VMS 540 ACD...So, is the 540 option similar to the 432 you guys are asking about? If I am way off, please tell me where to look/enable it.

On the two CPUs I found the 8 LEDS.
CPU1=Solid,off,off,off,off,off,off,off
CPU2=Blink,Solid,off,off,off,off,off,off
There are 3 green and 2 red larger LEDs near the top of the card. Both are 3 solid green and 2 blinking red, from top down.

Anyn help on where to decipher what that translates to?

As for getting my terminal connected to the slave, I can see that plug in the lower right so I may have to try and make a connector between that and my PC later.

I have not rest the system, but could do that after hours Friday. I'm worried about losing the configuration when the power goes off. How do I backup the configuration and save it someplace? What are the proper steps for shutting this thing down and powering it back up? Just flip the switch, or something thru the software?

Thanks much so far all. Please continue.
Posted By: nonameyet Re: Slave Communication Down. Now What? - 03/17/05 06:04 PM
Yes the 540 is GOOD that means You can go to 540 ports

as far as a reset.. Look at my Last Post.

as far as Saving the Database..If you have Your computer running Procomm? and it is hooked up to one of the rs232 ports usually 1 or 2 unless, your going thru a DDI then it could be ports 5 thru 10 , go to the Main menu and press ' D ' Then press ' S ' for System Backup, pick a Name for your backup, with the extenstion being ' . pgm '

for example " abcco.pgm " that will save the SYSTEM programming

look at the other options in the D screen, You can also save the ACD programming, the Auto Att programming and I think with some software versions Call Accounting (if you have it) Use the " .ACD " extenstion for ACD

The System program is about 975Kb and the ACD is about the same if not a little bigger, They Both won't fit on a 1.44MB disk though....SAVE THEM TO YOUR HARDDRIVE.


As far as Making a cable to hook-up to the 2nd cabinet... GOOD LUCK!! That connector is a 'Bastard ' config...I think its 37pin amphenol...Not 25 like standard..
Posted By: JJ Re: Slave Communication Down. Now What? - 03/18/05 04:01 AM
If you have a transient surpressor between your IO panel and the switch. Use one of those cables for the second cabinet.

Cable Pin out Port 1:
cable to DB25 or DB9
Green /Red 2 3
Blue/Red 3 2
--------
--------
Orange/Red 7 5
Yellow/Blue 20 4

Cable Pin out Port 2:
cable to DB2 or DB9
Green /Yellow 2 3
Blue/Yellow 3 2
--------
--------
Slate/Red 7 5
Yellow/Green 20 4


If you are shutting down system, you can flip flop ACPU cards as mentioned earlier.

If you do not need the second cabinet. System runs faster and performs better as stand-alone.

GooD Luck!!
Posted By: MagnusFox Re: Slave Communication Down. Now What? - 03/19/05 01:48 PM
Trust me I need more than luck at this point!

Info on cards within this system (both Cab1 and Cab2):
21640 MOH
21630 Fiber
21380-6 CPU

I swapped the CPUs, however I did not find any dip/jumpers different on the two cards.
I could not find any info on the CPU card I have. Perhaps this is a later version card able to determin which cabinet it is in?
When I put the Cab2 CPU in Cab1, it powered Cab1 for succesful call processing within that cabinet.
However, I could not use the default password to access the programming screens.
I was unable to logon to the system with CPU2 in Cab1.
With both CPUs swapped, there was no change in Cab1 being able to see Cab2.

I do not have a way to terminal into Cab2, as I am not taking the time to build a cable, so we will know know what CPU1 in Cab2 is doing.

Here is where I am now:
CPU1 in Cab1
CPU2 in Cab2
Cab1 works fine
Cab1 cannot see Cab2
LEDs on CPU1
Solid, Off, Off, Off, Off, Off, Off Off
LEDs on CPU2
Blink, Solid, Off, Off, Off, Off, Off, Off
LEDs on Fiber both Fiber cards
Red blink, Green Solid, Red blink
Ligth from both TX ports
Light from both strands of fiber on the RX side
Lights on all 4 of the side power units of each Cab

Open questions:
What do my LED lights indicate?
Why does CPU2 seem to have a different password than CPU1?
How do I diagnose the Fiber cards communication?
Posted By: JJ Re: Slave Communication Down. Now What? - 03/20/05 05:07 AM
When you looked at cabinet 2. Did it have the same features as cabinet 1?


Plug laptop into cabinet 1,and then goto "C" screen. Press Control "E", "E". This copies info from cabinet 1 to cabinet 2. You should see the numbers at bottom of screen jump up to larger numbers. Wait till numbers count back down before exiting this screen.

Ok, My bad... the dip-switches that control which cabinet is what are on the Fiber-mux cards.


I still think Your problem is a Power Supply.

Try swapping them around, But, before You do that, TAG each one with a number so, You know where it was originaly.

The way the IDS was designed each PS would power each Half of each Cabinet although the Power Supply on the RIGHT has a LOT more to Power...

I know You said You have lites on the power supplys, But what Have You got to lose at this point?

were You able to Backup the database?
Most of your options wont show up in second cpu. Cntrl E E coppies info from cab 1 to 2 Not Cntrl A A
Posted By: MagnusFox Re: Slave Communication Down. Now What? - 03/21/05 07:55 AM
I was able to backup the database, so I feel much better about doing all of this swapping around of stuff.

I will take a look at the Fiber Mux cards for dip switches and try a swap of those. Still no way to test them within the system?

When swapping the power supplies, I assume the Cab1 PSLeft can only be moved to Cab2 PSLeft. Same for the rigth PSs. Any tricks to swapping them before I get myself in too deep?
Posted By: MagnusFox Re: Slave Communication Down. Now What? - 03/21/05 08:00 AM
JJ, I'm not sure I get exactly what you are talking about. I am not able to look at Cab2, because I do not have a cable plugged into it (and cannot get one into it). I am unable to look at CPU2 when in Cab1 because I cannot get the default password to take.

With CPU1 in Cab1, I am unable to see Cab2, so will this copy stuff from the C screen work? Will it overwrite programming on Cab2 (not that I care too much as I have a backup of the programming)? How can I reset the PW for CPU2?
Posted By: nonameyet Re: Slave Communication Down. Now What? - 03/21/05 08:18 AM
You keep saying the password is different on the 2nd CPU...is it in DEFAULT?


Be REAL careful when trying to do a ' COPY '

If you're not at the Right place, You will COPY the DEFAULTED CPU over to the Good one...and LOSE all Your OPTIONS as well

THOSE OPTIONS are NOT on Your Backup.

(TRUST ME, I did this one time, it wasn't pretty)


as far as swapping Power supplys, They are ALL THE SAME...left can go on the right, right can go on the left...The only thing to make sure You do, is Plug the one on the left into the one on the right...
Posted By: DrJohn Re: Slave Communication Down. Now What? - 03/21/05 06:38 PM
Stupid question, but with the fiber connected to the second cabinet, pull the connectors off the first cabinet and look at the fiber strands. Since this is LED light you should not go blind looking at the strands. Is one of the strands red in color, and the other clear, or white?
Before trying to copy data from one cpu to the other...swap the two and make sure you have the one with all your options in cabinet one.Then from the "C" screen hold down cntrl and press "E" 2 times. Only do this when the system is not busy.
Based on the led's you have cabinet 2 see's cabinet one but 1 cant see two.The solid led is the cabinet that cpu is in the flashing leds are the 2nd and or 3rd cabinets connected
Posted By: MagnusFox Re: Slave Communication Down. Now What? - 03/22/05 06:55 AM
CPU1 has the default password loaded. I had to have a baord member dial in and reset the passwords to default a couple months back as I was unable to get into the system when I received the system. I'm not understanding how CPU2 does not have the same password.

I have checked the color of the light from the Fiber Mux, and everything is red on the far end of the strands.

I am unable to view CPU2's options, however, CPU1 does seem to have all of the options I need to run my system.

I'm kinda worried about this copy thing, but I will give it a go. I hate to do things durring business hours, so it may be some time before I can get to that.

Can the system self test check the power supplies or Fiber Mux cards?
Posted By: trico94 Re: Slave Communication Down. Now What? - 03/22/05 11:01 AM
When copying from cabinet one to cabinet two you must go to C screen. You will be looking at Cabinet 1. To coppy to cabinet 2 you must first hit 2 enter. This will change in upper left corner to Cab2 and then hit CTRL EE. After doing so you must wait for about 5 or 10 minutes. You will see the LRX/s speed increase when it goes back down it is safe to exit screen. Then you need to reset system.

If you have a transient surpressor between your IO panel and the switch. Use one of those cables for the second cabinet.


Do you have the transient suppressor?

If so, then You ' do have ' the 2nd cable that You could use for the 2nd cabinent.

the cable starts out in cabinet #1 on the bottom right, the other end plugs into the TS, on the other side of the TS there is another cable going to the MDF I/O panel.

Temporally disconnect the Transient Sup. plug the first cable directly into the I/O panel (till looking at Cab 1 at this point.

Take the ' other ' cable plug it into Cab 2, UNPLUG the first cable from the I/O panel and plug the 2nd cable in, NOW you can look at the CPU in cab 2.

Shut down the Complete system, take out the Fiber-mux cards(just get them off the backplane) turn on cab 2 ... Is there any database there? Does it match what WAS there?

Are the OPTIONS there?

can You ' see ' any cards there?

If he's showing 540 as an option then he's got an ACPU.Depending on the software level,the options are only downloaded into the first cabinet and are ported across to any other cabinets.This started in ACPU level 8 software encrypted downloads.

I'll take a look see at the TS and a cable to the second cab this weekend when I attempt to work on the switch next.

More next week all.
