Cisco ASR 901 10G Series Aggregation Services Router Hardware Installation Guide
OL-28105-02
Chapter 1 Introduction
Power Supply
• Install proper grounding for the site to avoid damage from lightning and power surges.
Warning
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network
voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some
LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.
Statement 1021
Warning
There is the danger of explosion if the battery is replaced incorrectly. Replace the battery only with
the same or equivalent type recommended by the manufacturer. Dispose of used batteries according
to the manufacturer’s instructions.
Statement 1015
Warning
This unit might have more than one power supply connection. All connections must be removed to
de-energize the unit.
Statement 1028
Warning
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 in order
to connect these interfaces metallically to OSP wiring.
Warning
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect the (Management Ethernet) ports only to intra-building or unexposed wiring or cable. The
intrabuilding cable must be shielded and the shield must be grounded at both ends. The intra-building
port(s) 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 as intra-building interfaces only (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 in order to connect these interfaces
metallically to OSP wiring.
