Warning
Statement 1021 SELV Circuit
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage
(TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and
WAN ports both use RJ-45 connectors. Use caution when connecting cables.
Warning Statement 1024 Ground Conductor
This equipment must be grounded. To reduce the risk of electric shock, never defeat the ground conductor or
operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical
inspection authority or an electrician if you are uncertain that suitable grounding is available.
Warning Statement 1028 More Than One Power Supply
This unit might have more than one power supply connection. To reduce risk of electric shock, all connections
must be removed to de-energize the unit.
Warning Statement 1029 Blank Faceplates and Cover Panels
Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages
and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other
equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all
cards, faceplates, front covers, and rear covers are in place.
Warning Statement 1030 Equipment Installation
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Warning Statement 1040 Product Disposal
Ultimate disposal of this product should be handled according to all national laws and regulations.
