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) and require isolation from the exposed outside plant (OSP)
cabling. To comply with NEBS requirements and 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 aroundyour bare wrist. Failure touse an ESDgrounding
strap could result in damage to the device.
