Ensure the cabinets are powered off.
Insert the NTCPU PCB into the CPU slot.
Insert an ESIU PCB in slot 1 of the Main Cabinet.
PCBs for slots 2-16 are not installed at this time.
Plug in all system telephones. A display telephone should be plugged into port 001 (extension
200).
When starting the system for the first time, hold the LOAD button on the NTCPU and turn
the AC Power Panel switch to ON. After approximately 3 seconds, release the LOAD button.
This performs a cold start on the Aspila EX system to make sure you're starting with a
defaulted system.
When powering up any other time, simply turn the AC Power Panel switch to ON.
Refer to Switch Settings and LED Indications on page 2-9 for NTCPU LED status.
Wait about three minutes for the system to boot. The telephone display at extension 200 will
show the Time/Date and extension number when the boot sequence completes.
Set the run/block switch to run UP on the ESIU in slot 1.
After setting the run/block switch DOWN for all SLIU/ESIU PCBs, insert SLIU/ESIU PCBs
in the Main Cabinet in sequential order.
The order in which SLIU and ESIU PCBs are physically inserted determines the num-
bering plan. The installer must install extension PCBs in order (i.e.; slot 1 first, slot 2 next,
slot 3 next, etc.) for a sequential numbering plan.
For example, with a 16ESIU in slot #1 (ext. 200-215), when 3 more 16ESIU PCBs are
installed in the following order, the numbering plan below would apply:
Order of

Set the run/block switch UP on each PCB.
