Determining the Operating Status
Turning on power to a Stinger unit
–
Using a number 2 Phillips screwdriver, remove the two screws that secure
the protective cover over the studs. Then remove the protective cover.
–
Using a 3/8-inch wrench or socket, remove the top locking nut from each of
the two studs (labeled -48V and RTN). Do not remove the bottom locking
nut.
–
Install the ring lugs onto the appropriate posts.
Note
You can optionally ground the chassis to the enclosure by attaching dual
mount ground lugs to the ground terminal on the back of the unit. Do not
remove the ground lugs.
–
Reinstall the locking nut onto each post, then use a 3/8-inch wrench or
socket to tighten the nut.
–
Reinstall the protective cover with the two screws.

Turning on power to a Stinger unit

Caution
Do not turn on power to a Stinger unit without a control module installed
in the chassis. Starting up a unit with no control module installed can damage
hardware components.
To turn on power to the unit, press the power switch on each power filter to the
ON ( | ) position.
All Stinger status lights, except the MASTER light, momentarily turn ON just after
startup.
On the control module, the MAJOR status light turns ON at startup. It then starts
blinking slowly while the control module runs its POST in the boot loader. It
continues to blink while the control module loads its operational code from the
PCMCIA flash card. If the control module successfully loads its operational image
from the PCMCIA flash card and again passes POST, the MAJOR status light turns
OFF. If the MAJOR status light continues to blink, it indicates a failure.
