IBM TS3100 Setup, Operator, And Service Manual page 26

CAUTION:
The intra-building ports of the equipment or subassembly are only suitable for connection to
intra-building or unexposed wiring or cabling. The intra-building ports of the equipment or
subassembly must NOT be metallically connected to interfaces that connect to the OSP or its wiring.
These interfaces are designed for use only as intra-building interfaces (Type 2 or Type 4 ports as
described in GR-1089-CORE, Issue 4), and require isolation from the exposed OSP cabling. The
addition of primary protectors is not sufficient protection in order to connect these interfaces
metallically to OSP wiring.
An external Surge Protective Device (SPD) is not required for operating this library.
This product can be installed in a network telecommunication facility or location where the NEC applies.
