Do not work on the system or connect or disconnect cables during
periods of lightning activity.
Before working on equipment that is connected to power lines, remove
jewelry (including rings, necklaces, and watches). Metal objects will
heat up when connected to power and ground and can cause serious
burns or weld the metal object to the terminals.
Do not stack the chassis on any other equipment. If the chassis falls, it
can cause severe bodily injury and equipment damage.
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 terminal block plug.
Ethernet cables must be shielded when used in a central office
environment.
If a redundant power system (RPS) is not connected to the switch,
install an RPS connector cover on the back of the switch.
Read the wall-mounting instructions carefully before beginning
installation. Failure to use the correct hardware or to follow the correct
procedures could result in a hazardous situation to people and damage
to the system.
