- Slots CN5-CN8 are only available with the 8 slot cabinet.
- A 4 slot cabinet can only accept two 16DSTU PCBs.
- In an 8 slot cabinet, you can have only two 16DSTU PCBs per power supply.
!! Important !!
Install telephones connected to DSTU and ASTU PCBs as on-premise extensions only.
!! Caution !!
• Do not plug in the CPU PCB hot (i.e., with the system power applied).
• You can plug in ASTU and ATRU PCBs hot as required.
• You can plug in DSTU PCBs hot provided you first disconnect the station cabling from the PCB.
