URGENT HELP ON MD110 1

[ladeeh]

Hi gentlemen,
I have this big problem of link cut-off between two LIMs (MD110 BC 8) which were initially connected by2mbp/s radio through group switch. The remote LIM (160 extensions) loads from the main LIM (320 extensions), but now that the radio link is down, the remote LIM went off due to power problem.
I have less than a week to bring-up the remote as stand alone or face the music. There is no immediate plan to replace the faulty radio link due to insurance related issues.
I am now considering two options:
1. Take the HDU and IPU boards from the main LIM to the remote LIM.
2. Physically carry the remote LIM to the main LIM and connect direct through the GJUL4 then boot up and relay on the MEU to sustain the PBX to return to the remote site.

I am fairly knowledgeable on the programming and I understand that the first option may not give a stable boot up else some configurations have to be effected.
Although the PBXs in question are very old, I have been mandated to solve this problem before my proposal for upgrade or replacement will be entertained.
This forum is capable in providing solutions to various problems. Let mine not be an exception.

Please advice.

carry to remote lim to the main lim, connect some good batteries and let it reload, once up, return the lim (powered on)

whosrdaddy ,
I have tried option 2 as sugested but I am still having problem of GJUL4 to GJUL4 connection between the 2 LIMs. The remote LIM is not seeing the master LIM. code 2300 on my LPU display. I am using the coax cable from the faulty radio.
Pls advice further.

It seem to be a faulty LPU board in lim 2 !

 

[ladeeh]

The coax cable Iam using still passes through the PCM equipment but NOT through the faulty radio itself.
Does GJLU4 to GJLU4 connetion between 2 LIMs require any special cable?

Mundus,Thanks. I have tried the LPU board from the main LIM and it is still the same code 2300

 

[whosrdaddy]

mundus is right! 23xx indicates your LPU has a faulty watchdog, replace LPU is the message...

Does GJLU4 to GJLU4 connetion between 2 LIMs require any special cable?
No, but you have to reverse the sender and transmitter in one of the GJUL-4 end.

 

[ladeeh]

Ok Mundus, pls send me the pin out so that I can make a fresh cable.

ladeeh, the easiest way is take an existing coax cable, remove the covers on one end and reverse the covers (in effect turning one plug upside down)

Thats all I did to setup my 2 lim lab system.
