Environmental Monitoring Temperature Sensor
REVIEW DRAFT - CISCO CONFIDENTIAL
Check the power at your site before router installation (and periodically after installation) to ensure clean
•
power (free of spikes and noise) is being received.
Always disconnect the power source and unplug the power cable before working on the router.
•
Install proper grounding for the site to avoid damage from lightning and power surges.
•
Introduction
Warning
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
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
Environmental Monitoring Temperature Sensor
The Cisco ASR 901S Series Aggregation Services Routers has a temperature sensor to detect over temperature
conditions inside the chassis. The over temperature detection trips at 158°F (70°C). This condition is reported
to the processor as an interrupt, where the software generates the appropriate alarms. If the router reaches a
temperature of 181.4°F (83°C), the power supply cycles itself to prevent the router from exceeding the
maximum temperature while being powered up.
The following table provides the over temperature alert settings.

For environmental specifications, see table 8 in Product Specifications, on page 72.
External Connections and Chassis Cable Ports
When connecting the router internal ports to external cables or exterior devices, the router cables must be
threaded through the chassis cable ports designated for this purpose. Some chassis ports are reserved for
specific cables and remaining ports can be used based on the network configuration and cabling requirements.
For details about the interfaces, see Cisco ASR 901S Series Aggregation Services Router: Top and Bottom
View, on page 5.
The cable connectivity can be provided as follows:

External Connections and Chassis Cable Ports
REVIEW DRAFT - CISCO CONFIDENTIAL
The power input is provided on the extreme right through an IP-65 compliant gland for DC. An ordinary
•
DC cable can be routed through the gland. For AC inputs, a special IP-65 compliant connector system
should be used. The AC input cable can be removed from the system without opening the door.
Each SFP port is connected with an LC-LC patch cable from the SFP module to the bottom panel. For
•
the external connectivity, an LC cable system with IP-65 sealing should be used.
For configurations with two or three SFP ports, one or two copper ports will have an internal patch cable
•
arrangement. For these configurations, an external RJ-45 connection with IP-65 sealing should be used.
For configurations with four SFP ports, the RJ-45 connections for the copper ports with common copper
•
cables (non IP-65 compliant) should be used. These cables can be routed through the four-wire gland
shown adjacent to the power entry cable.
The alarm port has a single Cat5e cable routed through the four-wire gland.
•
The management, Ethernet, and console ports are usually not used in the OSP because the access to the
•
router is limited (the Wi-Fi interface is used instead). However, when these ports are used, the
corresponding cables should be routed through the four-wire gland.
Note
In certain configurations, like 4 SFPs, 2 CUs, and alarm, it is not possible to route the
console and management ports through the four-wire gland.
For the optical ports, multimode patch cables are supplied by default with the router. The single mode
•
cables can be ordered separately.

•
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.
•
Caution
OL-29732-01 15
For the safety of your equipment, periodically check the resistance value of the antistatic wrist strap. It
should be between 1 and 10 Mohm.

Preparing to Install the 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 equipment rack 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.
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:
Site Planning
REVIEW DRAFT - CISCO CONFIDENTIAL
•
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 15 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.
