hicom 300 analog phones not ringing !

[mubshar]

Hi,

I am Having a ringer problem with all analog lines of hicom 300 Seimens, Digital extns are working fine. I am new to this system need help and knowledge, documentations to understand the hardware and programming.

I need to know the default passwords and acc. ? I am using comwin ?

Thanks !

There are two possible problems for this that I can think of right off the top of my head, and some of it depends on which version of the 300 you have - whether it is E, EX or EP.

The first thing is that normally on the E and the EX every other cabinet will have a Ring Generator card. The card is normally in the very first slot on the left if it is in the cabinet, and without making the effort to look I believe it is labelled RCG. That card normally has an LED on it that flashes in the normal ring cadence, and you can hear relays on it clicking on and off when analog phones ring. The cabinet that has the board in it normally has a cable to the next cabinet up so that each board can serve 2 cabinets. You can try yanking that board out (using the tool) and then push it back in so it reseats and reloads its software and see if that helps.

The other problem, and I have especially seen this on the 30EP systems, is there could be an issue with the power supply for the shelf. I'm not sure where the E and EX systems get their ring voltage from (one of the power supplies, obviously) but I know the EP power supply provides ring voltage per cabinet. I have a two cabinet system and one of the cabinets has a failed power supply and will not ring analog phones. Becuase neither of those two cabinets is too stressed, after I found out the replacement power supply was in excess of $1000 I just reconfigured my system and moved the board from the bad cabinet into the other cabinet that I know was properly ringing phones. That solved my immediate problem, but long term that power supply is still bad!

Please note that what I did to fix MY problem is not as simple as moving the board, and required several hours of work!

Its a hicom 300 H pbx system, Thanks alot for supporting. I will check with this if it solves problem, but i need more knowlegde about it. !

I believe the Hicom 300H systems are all running the EP cabinets unless they have been upgraded from a lower system. Hopefully it's not a bad power supply as they are over a grand if memory serves me correct.

donb01,

How i can i login to the system using console cable from my laptop, what software do i need for hicom 300 H ?

If i will try swapping the powersupply with other power hope it works ?

comwin soft can be used to access the system ?

I dont know the Account ID & password of the site, how can i retrieve it, or reset it ?

Thanks !

Plug the Cable from your laptop into the 25-pin port that should be on the right side of the Custom Callout Adapter. That will get you a unix login prompt using 115200, 8, N, 1.

The tech use Comwin to access 9006, but I have never done it before. I'm kind of a rookie at Comwin and I still have to fire it up using the assistant on HiPath 4000. I can run it, but I don't know how to kick off the connection process. I assume you would create a new serial connection using the above COM parameters and whatever serial port you have the cable connected to, and then tell it to connect. I don't think when you use Comwin that you have to worry about the keyboard mapping files you need for Procomm. If it's a 30EP the best way to administer it with LC-Win software. Usually they will leave the install CD inside the cabinet - unless your people moved it.

I can't help you with your password for the rsca login - that is usually left up to the vendor that installs the system. If you happen to be in WI and have Norstan/BlackBox as your vendor I could give you an educated guess, but otherwise I can't. You can try using "password1" (that is a numeral one) which is sometimes used by techs as a temporary password when it makes you change it - until you can login and change it back to what it was.

If there is anyone else there that used to administer it on your company's behalf there might also be a customer login set up for you, and manybe there are notes about it.

If you have a 2 cabinet system, and you have NO Analog cards installed in the second cabinet, you probably could swap the power supplies between the two cabinets and it will probably fix the problem. I have a lot of spare parts, but I don't have one of those power supplies, and I wasn't about to spend $1000 to buy one just to troubleshoot a problem!

Good luck!

I have only one cabinet ?? Your further suggestions on it? Thanks !

 

[donb01]

If you can get your hands on a spare power supply without dropping a grand on it (or however much you can deal with spending if it doesn't work) then try that. Otherwise, I never fixed my own because I didn't want to pay for it and just migrated all my Analog cards to the cabinet with the working power supply.

 

[mubshar]

Swapped the power supply with the working one, still the problem persists ? no alarms, no programming errors !

Do you have an RCG board in the system on the left side? Normally I don't think you need one with only one cabinet, but there might be one. If there is, pull it out and then push it back in to reseat and reload it. See if that makes a difference. Otherwise, assuming phones have rang before and just suddenly stopped, I don't know if any other hardware problem that would cause that.

Just an off the wall question here, but if you pick up one of the phones do you hear a steady dial tone or a broken dial tone?? If it's a broken dial tone first dial # # 5, hang up, and then dial # # 9 1. The first one shuts off do not disturb, and the second one removes all forwarding set up by the phone user. The broken dial tone can indicate the phone is forwarded, on do not disturb, or there is a voicemail message waiting.

No use !!! cant solve out, maybe the backboards or the slot has become faulty ???

 

[donb01]

Incidentally - I may have transposed those letters - it might be RGC. I would have assumed if there was one you might have assumed that, but.... just in case.

If you have reseated the board, if any, and it has a green LED lit on the front that is going on and off at a rate of every 2 seconds maybe, then the board should be good. If you have swapped out the power supply then you know that is good. There isn't much else to do. There are jumpers on the back of the cabinet that have some relevance to ring voltage, but no one would have ever touched any of that stuff so I don't even give it consideration. The only other thing would be if the phones were set not to ring, but again, I doubt that ALL of them would be set that way.

That's as far as I can take you in the troubleshooting - sorry.

Check for the RG MOD card, if you do not have one on any shelf then check the backplanes for a 'gold ringer'.
They are known to go faulty.
Part Number S30122-H5929-X
Newer ones are actually silver in colour.
There are 4 settings on them depending on the territory.

The gold ringer looks like a large pack of cigarettes bolted on to the back plane
You will need to power down the shelf to remove and refit the new one
Then power it up again
