To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and
safety, for Ethernet RJ-45 ports, use only shielded Ethernet cables that are grounded on both
ends. In a NEBS installation, all Ethernet ports are limited to intrabuilding wiring.
Caution
The intrabuilding ports of the equipment or subassembly are only suitable for connection to
intrabuilding or unexposed wiring or cabling. The intrabuilding 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 intrabuilding interfaces (Type 2 or Type 4
ports as described in GR-1089-CORE), and require isolation from the exposed OSP cabling.
The addition of primary protectors is not sufficient protection to connect these interfaces
metallically to OSP wiring.
Caution
Products that have an AC power connection are intended for deployments where an external surge protective
device (SPD) is used at the AC power service equipment as defined by the National Electric Code (NEC).
This product is designed for a common bonding network (CBN) installation.
This product can be installed in a network telecommunication facility or location where the NEC applies.
An electrical conducting path shall exist between the product chassis and the metal surface of the enclosure
or rack in which it is mounted or to a grounding conductor. Electrical continuity shall be provided by using
thread-forming type mounting screws that remove any paint or nonconductive coatings and establish a
metal-to-metal contact. Any paint or other nonconductive coatings shall be removed on the surfaces between
the mounting hardware and the enclosure or rack. The surfaces shall be cleaned and an antioxidant applied
before installation.
The grounding architecture of this product is DC-isolated (DC-I).
DC-powered products have a nominal operating DC voltage of 48 VDC. Minimal steady-state DC operating
voltage is 40.5 VDC. Reference American National Standards Institute (ANSI) T1.315, Table 1.
Standard Warning Statements
This section describes the warning definition and then lists core safety warnings grouped by topic.
This warning symbol means danger. You are in a situation that could cause bodily injury. Before you
work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with
standard practices for preventing accidents. Use the statement number provided at the end of each warning
