14. Powering Up the System

The system should not be powered up until the appropriate point in the initialization
procedure (which is documented in the Guide to DNC Base Software Installation,
450-1011-302). However, should an installed system require reinitialization, use the
procedure below.
Your system may or may not be equipped with a power switch on the Input Jumper
Assembly. (See Fig. 14-1.) If your system is so equipped, you power up the system
by setting the switch to ON. If your system is not equipped with a power switch, it
is powered up when plugged into an ac source (115 or 220 Vac).
Some applications may use an uninterrupted power supply (UPS). If so, make sure
the UPS is powered up first.
To reinitialize a system already in operation, power it off and power it up again after
about 30 s. If the system is equipped with a switch, switch it to OFF, then to ON. If
it is not equipped with a switch, unplug the power input cable from the cabinet input
jumper assembly, then plug it in again.
