Safety with Electricity

•Never assume that power is disconnected from a circuit; always check.
•Never perform any action that creates a potential hazard to people or makes the equipment unsafe.
•If an electrical accident occurs, proceed as follows:
◦Use caution, and do not become a victim yourself.
◦Switch off power to the router.
◦If possible, send another person to get medical aid. Otherwise, determine the condition of the
victim, and then call for help.
◦Determine whether the person needs rescue breathing or external cardiac compressions; then take
appropriate action.
In addition, use the following guidelines when working with any equipment that is disconnected from a power
source, but still connected to telephone wiring or network cabling:
•Never install telephone wiring during a lightning storm.
•Never install telephone jacks in wet locations unless the jack is specifically designed for it.
•Never touch un-insulated telephone wires or terminals unless the telephone line is disconnected at the
network interface.
•When installing or modifying telephone lines, use caution.
Preventing Electrostatic Discharge Damage
Electrostatic Discharge (ESD) can damage equipment and impair electrical circuitry. ESD can occur when
electronic printed circuit cards are improperly handled, and can cause complete or intermittent failures. When
removing and replacing modules, always follow ESD prevention procedures:
•Ensure that the router chassis is electrically connected to earth ground.
•Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. To channel unwanted
ESD voltages safely to ground, connect the clip to an unpainted surface of the chassis frame. To guard
against ESD damage and shocks, the wrist strap and cord must operate effectively.
•If no wrist strap is available, ground yourself by touching a metal part of the chassis.
For the safety of your equipment, periodically check the resistance value of the antistatic wrist strap. It
should be between 1 and 10 Mohm.

Prerequisites
Before installing the Cisco ASR 901S Series Aggregation Services Router, it is important to prepare for
installation by :
•Preparing the site (site planning) and reviewing the installation plans or method of procedures (MOPs).
•Unpacking and inspecting the Cisco ASR 901S Series Aggregation Services Router.
Site Planning
Ideally, you should have prepared the installation site beforehand. As part of your preparation, obtain a plan
of the site and the exact location where the Cisco ASR 901S Series Aggregation Services Router would be
housed. Determine the location of any existing routers and their interconnections, including communications
and power.

4OL-29732-02
Preparing to Install the Router
Prerequisites

All personnel involved in the installation of the router including installers, engineers, and supervisors should
participate in the preparation of a Method of Procedure (MOP) for approval by the customer.
Site Environment
Every network application is a unique installation. Before installing the Cisco ASR 901S Series Aggregation
Services Router, you should perform a site survey to determine the optimum use of networking components
and to maximize range, coverage, and network performance.
Consider the following operating and environmental conditions when performing a site survey:
•Data rates—Sensitivity and range are inversely proportional to data bit rates. The maximum radio range
is achieved at the lowest workable data rate. A decrease in receiver sensitivity occurs as the radio data
increases.
•Antenna type and placement—Proper antenna configuration is a critical factor in maximizing radio
range. As a general rule, range increases in proportion to antenna height. However, do not place the
antenna higher than necessary, because the extra height also increases potential interference from other
unlicensed radio systems and decreases the wireless coverage from the ground.
•Physical environment—Clear or open areas provide better radio range than closed or filled areas.
Always follow ESD-prevention procedures described in Preventing Electrostatic Discharge Damage,
on page 3 to avoid damage to equipment. Damage from static discharge can cause immediate or
intermittent equipment failure.
•Obstructions—Physical obstructions such as buildings, trees, or hills can hinder performance of wireless
devices. Avoid locating the devices in a location where there is an obstruction between the sending and
receiving antennas.
Method of Procedure
Part of site preparation includes reviewing installation plans or method of procedures (MOPs). An example
of a MOP that includes pre-installation checklist of tasks, considerations to address and agree upon before
proceeding with the installation, is as follows:
•Read this hardware installation guide.
•Assign personnel.
•Determine protection requirements for personnel, equipment, and tools.
•Evaluate potential hazards that may affect service.
•Schedule time for installation.
•Determine space requirements.
•Determine power requirements.
•Identify required procedures or tests.
•Make a preliminary plan that locates each Cisco ASR 901S Series Aggregation Services Router that
you plan to install.
•Verify the list of replaceable parts for installation (screws, bolts, washers, and so on).
