TN747B Install TN747B Install PowerSp (IS/IT--Management) (OP) 6 Nov 01 17:59 I have to install a TN747B board for CO lines. I just need to know if I can install in any slot, or is there a specific slot to use. And do I have to powerdown the system..? RE: TN747B Install pbxman (MIS) 6 Nov 01 21:06 It's hot-swappable..just plug it into any slot, and configure away.Just to make sure - it's for a Definity Prologix or System 75 right?If so - just plug it in. No need to power-down or worry about slots. PbxmanSystems Administrator Please let Tek-Tips members know their posts were helpful.
