Is this card hot swapable and dose anyone know where to get a manual?

I always power down when swapping cards

try the manuals link at the top of the page here

Thanks for the quick reply but I couldent find the DX2 sys32 manual in the all types private section or for sale in the telemanuals sections this system has been up for years and I worried about program loss on power down

you need to find out just what system you have , I suspect its a "I series "

what phones is it using ?
