Safety Requirements
Warning
Ethernet cables must be shielded when used in a central office environment.
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 terminal block plug.
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, and front covers are in place.
Warning
When installing the unit, the ground connection must always be made first and
disconnected last.
Warning
This equipment is intended to be grounded. Ensure that the host is connected to earth
ground during normal use.
Warning
This equipment needs to be grounded. Use a green and yellow 12 to 14 American Wire
Gauge (AWG) ground wire to connect the host to earth ground during normal use.
Warning
Incorrect connection of this or connected equipment to a general purpose outlet could
result in a hazardous situation.
Warning
Read the installation instructions before you connect the system to its power source.
Warning
Only trained and qualified personnel should be allowed to install, replace, or service
this equipment.
Warning
The ISDN connection is regarded as a source of voltage that should be inaccessible to
user contact. Do not attempt to tamper with or open any public telephone operator
(PTO)-provided equipment or connection hardware. Any hardwired connection (other
than by a nonremovable, connect-one-time-only plug) must be made only by PTO staff or
suitably trained engineers.
Warning
Do not stare into the beam or view it directly with optical instruments.
