The following section provides details about the internal interface ports (within the cable bay area) supported
on Cisco ASR 901S Series Aggregation Services Router.
•
Gigabit Ethernet and Fast Ethernet Ports—The router supports two Gigabit Ethernet and Fast Ethernet
Cu (RJ45) ports. The ports support standard 100/1000 Base-T Ethernet features including auto-MDIX.
•
Management Ports—The router supports two types of management port: an RS-232 serial console and
10/100 Base-T Ethernet ports. Both ports use the RJ45 connector and are accessible via the cable gland
interface. .
Introduction
The RS-232 serial console port can operate with flow control signals clear-to-send and ready-to-send
◦
and without flow controls. The default baud rate is 9600 and can be reconfigured to operate at a
maximum baud rate of 115200.
The 10/100 Base-T Ethernet port can auto-negotiate or force to operate at either 10 Mbps or 100
◦
Mbps, half or full duplex. The traffic on this port is isolated from switching ports.
•
Alarm Inputs— The router supports four dry-contact alarm inputs. These alarm inputs can be configured
to trigger an open or closed alarm, individually. Each input can be provisioned to generate minor, major,
or critical alarms.

Safety Precautions
Observe the following general safety precautions and recommendations in planning the source power
requirements for the Cisco ASR 901S Series Aggregation Services Router (for additional safety information,
see Safety Guidelines, on page 15).
Cisco ASR 901S Series Aggregation Services Router Hardware Installation Guide
10 OL-29732-01
Introduction
Environmental Monitoring Temperature Sensor
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.
•
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
Environmental Monitoring Temperature Sensor
The Cisco ASR 901S Series Aggregation Services Router has three temperature sensors on board to detect
over temperature conditions inside the chassis.
•
Inlet temperature sensor—Monitors the local air temperature of the board.
Note
•
Board temperature sensor—Monitors the air temperature exiting the chassis.
•
CPU temperature sensor—Monitors the air temperature on the CPU.
When over temperature is detected it is reported to the processor as an interrupt, where the software generates
the appropriate alarms. If the router reaches a temperature of 248°F (120°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.
The term inlet used here refers to the air circulating from the bottom to the top within
the router chassis; inlet does not refer to air entering through an inlet or through the fans
because there are no air vents or fans on the router.

External Connections and Chassis Cable Ports
When connecting the router internal ports to external cables or exterior devices, you must thread the router
cables 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 your network configuration and cabling requirements.
Note
When you make router cable connections through these ports, you must use cable glands as described in
Using Cable Glands, on page 58, to protect the router interior from environmental elements, including
moisture, heat, cold, and dust. Failure to use cable glands with the chassis cable ports can result in damage
to the router.
The cable connectivity can be provided as follows:
The power entry is provided on the extreme right of the bottom panel, which is through a DC connector
•
for DC (FD chassis). Use an outdoor-rated DC cable that can be routed through the DC connector. For
AC inputs (on a FA chassis), use a special IP-65 compliant AC connector. The AC or DC input cable
can be removed from the router without opening the router cover.
Each SFP port can be connected with an LC-LC patch cable from the SFP module to the faceplate. For
•
external connectivity, an LC cable system a with IP-65 sealing should be used.
Cisco ASR 901S Series Aggregation Services Router Hardware Installation Guide
12 OL-29732-01
Introduction
External Connections and Chassis Cable Ports
For configurations where the number of SFP ports is 2 or 3, one or two copper (Cu) ports will have
•
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, use outdoor-rated, shielded, Cat5e copper cables with RJ-45
•
connections for the copper ports. These cables can be routed through the three-wire gland shown adjacent
to the power connector on the bottom panel of the router.
The alarm port has a single Cat-5e cable routed through the three-wire cable 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 three-wire cable gland.
Note
In certain configurations, like four SFPs, two Cus, and alarm, it is not possible to route
the console and management ports through the three-wire cable gland.

Preparing to Install the Router
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:
Preventing Electrostatic Discharge Damage
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.
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
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 :
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.
Preparing the site (site planning) and reviewing the installation plans or method of procedures (MOPs).

Preparing to Install the Router
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 Environment
•
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 17 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).
