Hazard Identification, Notices, and Notes
This manual uses standardized graphic conventions to promote safe practices by technicians

getting labels. This section explains the conventions used and their meanings.

WARNING
Electrical Shock . Disconnect the computer from all power sources before opening the
cover and working inside the chassis. Failure to take this precaution could result in
electrical shock and injury.
CAUTION
Pinch Hazard . Keep fingers clear of the edges of the faceplate when inserting a trunk
module into the chassis. . . .
NOTICE
Equipment Damage Hazard . Only use a single appropriate power adapter. Do not
connect a U.S. power supply and a Universal power supply to the same device. Also,
when using the Universal Power Supply with a barrel connector, no devices (for
example, hubs) should be inserted between the KS/SLA jack on the adapter and the
LAN jack on the endpoint because power is supplied through the cable.
IMPORTANT
The chassis must connect firmly to earth ground at the Ground Lug.
NOTE Commercially available premoistened towels provide adequate cleaning.
