General Electrical Safety Guidelines and Warnings
WARNING: Certain ports on the device are designed for use as intrabuilding
(within-the-building) interfaces only (Type 2 or Type 4 ports as described in
GR-1089-CORE, Issue 4) and require isolation from the exposed outside plant
(OSP) cabling. To protect against lightning surges and commercial power
disturbances, the intrabuilding ports must not be metallically connected to
interfaces that connect to the OSP or its wiring. The intrabuilding ports on
the device are suitable for connection to intrabuilding or unexposed wiring
or cabling only. The addition of primary protectors is not sufficient protection
for connecting these interfaces metallically to OSP wiring.
CAUTION: Before removing or installing components of a device, attach an
electrostatic discharge (ESD) grounding strap to an ESD point and place the
other end of the strap around your bare wrist. Failure to use an ESD grounding
strap could result in damage to the device.
