Safety Warnings
Safety warnings appear throughout this publication in procedures that may harm you if you perform them incorrectly. A warning symbol precedes each warning statement. The warnings below are general warnings that are applicable to the entire publication.
![]() Warning |
An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure that no exposed portion of the DC-input power source wire extends from the connector(s) or terminal block(s). Statement 122 |
![]() Warning |
AC connected units must have a permanent ground connection in addition to the power cable ground wire. NEBS-compliant grounding satisfies this requirement. Statement 284 |
![]() Warning |
High leakage current—earth connection essential before connecting to system power supply. Statement 342 |
![]() Warning |
Power Cable and AC Adapter - When installing the product, please use the provided or designated connection cables/power cables/AC adaptors. Using any other cables/adaptors could cause a malfunction or a fire. Electrical Appliance and Material Safety Law prohibits the use of UL-certified cables (that have the "UL or CSA" shown on the code) for any other electrical devices than products designated by CISCO. The use of cables that are certified by Electrical Appliance and Material Safety Law (that have "PSE" shown on the code) is not limited to CISCO-designated products. Statement 371 |

![]() Warning |
Class 1 LED product. Statement 1027 |
![]() Warning |
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. Statement 1029 |
![]() Warning |
Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030 |

Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040 |
![]() Warning |
To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 104°F (40°C). Statement 1047 |
![]() Warning |
Stability hazard. The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before you slide the unit out for servicing. Failure to stabilize the rack can cause the rack to tip over. Statement 1048 |
![]() Warning |
The chassis should be mounted on a rack that is permanently affixed to the building. Statement 1049 |
![]() Warning |
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051 |
![]() Warning |
