Attendant Console m2250 failure code 8ch

[bdabson]

Hi,

I have a couple of 2250 consoles showing

failure code 8ch

all the time on the screen
all the built in diagnostics come back fine, no sticky keys

but I can't identify what this error code means

can anyone throw some light on this as no Nortel documentation has this code.

cheers

The message could be interpreted a few different ways.

Have a look for a document: 553-3001-367_3.00

It is known as Telephones and Consoles, Description Installation and Maintenance.

Under Attendant Consoles / Operation / M2250 Failure Codes, you may find the answer.

be careful though, sometimes the 8 and B look very much the same.

thanks this is the main NTP source I checked.
the Failure code is definitely 8CH
which is not listed in the NTP you refer to.

All 8xH codes refer to some kind of component or chip fault so I will have to work on this basis.

Again any other ideas would be welcome.

cheers
