SYSTEM SHUTDOWN
Powering Off the System
Observe the following when powering off the system.
• It is advisable to make a back up of the customer configuration before powering off.
• DO NOT power off by disconnecting the AC (or DC for battery back up) power. ALWAYS use
the push button switch on the front of the PSU. There may a short delay whilst the NTCPU
becomes idle before the system powers down.
• For systems with an expansion cabinet installed powering off the expansion cabinet's PSU will
not power off the system. Power off the main cabinet's PSU, this will power off both the main
and expansion cabinet.
• All calls in progress will be cut off when the system is powered off, if COIU power fail ports are
installed they will become operational.
• All user's setting (e.g call forward, camp-on etc) will be kept.
Resetting the System (Hot Start)
Observe the following when resetting the system.
• DO NOT reset a system with the RESET switch on the NTCPU (SW2), this performs a forced
reset regardless of the operating state of the NTCPU.
• Always reset the system by powering off (and then on) the PSU (see instructions above). This
will wait for the NTCPU to become idle before powering down.
For further information on Hot Start and Cold Start for the system refer to CPRU Installation
(Figure 2-4) (page 2-12).

To save customer data a blank PC-ATA card is required. Insert the card
into the NTCPU and, using Program 90-03, save the software to the PC-
ATA card. (Program 90-04 is used to reload the customer data if neces-
sary.) Note that a PC-ATA card can only hold one customer database.
Each database to be saved will require its own separate card.
