Overview

The Cisco RF Gateway 10 (RFGW-10) is a Carrier Class Universal Edge QAM (UEQAM) platform that
offers concurrent support for Standard and High Definition Digital Broadcast Television, Switched
Digital Video (SDV), Video on Demand (VoD), and DOCSIS/Modular CMTS services.

The Cisco RFGW-10 UEQAM is a chassis-based product that is based on open standards with superior
performance, capacity, power consumption, ease of management and scalability. All components of the
Cisco RFGW-10 UEQAM are designed for high availability including dual Supervisor and Ethernet
switching line cards, N:1 Universal Edge QAM line cards, dual Timing and Control line cards, dual load
balancing and load sharing Direct Current Power Entry Modules (DC PEMs) and integrated RF
switching modules.

The Cisco RFGW-10 is part of the Cisco Cable ecosystem, and is fully integrated and tested as part of
the Cisco Digital Broadband Delivery System (DBDS) video solution and Cisco uBR10012 DOCSIS 3.0
and Modular CMTS solution.

The Cisco RFGW-10 is a centralized switching architecture leveraged from the Cisco Catalyst 4500
Series switches. The Cisco RFGW-10 is a 13 rack unit carrier class, modular chassis designed for
providing front-to-back airflow and system level redundancy. All chassis components are hot-swappable
and redundant. The chassis supports “wire-once” cabling for RF line cards and an integrated dual-zone
RF switch matrix. The supervisor engine provides non-blocking, Layer 2 to Layer 4 switching with the
addition of wire-speed 10-Gigabit Ethernet uplinks, 136-Gbps capacity, and 102-mpps packet
throughput.

The Cisco RFGW-10 system is a UEQAM that supports both upstream and downstream RF cards over a
frequency range of 5 MHz to 1.2 GHz. The initial line card release is a UEQAM downstream card that
supports the DOCSIS (1.0/2.0/3.0), the EURODOCIS, and J-DOCSIS specifications.

Based on the Cisco IOS networking software, the Cisco RFGW-10 supports advanced switching and
routing features.

Cisco RFGW-10 Functional Overview

The Cisco RFGW-10 is a Carrier Class Universal Edge QAM (UEQAM) platform that offers concurrent
support for Standard and High Definition Digital Broadcast Television, Switched Digital Video (SDV),
Video on Demand (VoD), and DOCSIS/Modular CMTS services. The Cisco RFGW-10 is an edge
modulation device that aggregates multiple High Speed Data and/or Video sources, processes and
modulates the digital MPEG content, and forwards the QAM modulated MPEG data to the subscriber
side devices (cable modems and set-top boxes).

1-2

The initial application of the Cisco RFGW-10 is primarily as a downstream data delivery system
(downstream from the Cisco RFGW-10 to the cable modem or set-top box). External data and
management sources (VoD servers, MCMTS devices, DNCS, and so on) aggregate into the system via
the Gigabit Ethernet and 10 Gigabit Ethernet interfaces on the Supervisor and the RF line cards. The

Cisco RF Gateway 10 Hardware Installation Guide

OL-16264-04

Chapter 1 Overview

Cisco RFGW-10 Functional Overview

Cisco RFGW-10 architecture is based on a centralized Layer 2 to Layer 4 Ethernet switch fabric. All
external Ethernet interfaces, whether on the line cards or on the Supervisor front panel, terminate at the
Supervisor engine’s switch fabric. Traffic on any of the external interfaces can be routed to any card in
the chassis.

The supervisor engine receives either DEPI (DOCSIS) data or Video data (MPEG/UDP/IP) and forwards
the data to the RF line cards based on either the DEPI session content (IP/L2TP) or encapsulated video
session information (IP/UDP). All data path traffic is terminated at the line cards. The supervisor
receives data traffic, classifies the traffic, and forwards the data traffic to the line cards.

Control traffic for DOCSIS (DEPI mode), Video, and HA functionality is terminated on the Supervisor.
Local video mode (CLI, GUI, SNMP), remote video mode control plane (DNCS, GQI), and Native video
mode (GQI v2, object model) are implemented in the IOS and terminate at the Supervisor.

The Cisco RFGW-10 supports redundant, DTI source device inputs as part of the system clocking
architecture. It includes redundant DTI/TCC cards, which support DTI client functionality.

All line cards and modules are redundant. The Supervisors (RPR, SS), TCC, and DC PEMs support 1:1
redundancy. The line card slots can be enabled in either a single N+1 redundancy configuration or a dual
redundancy configuration (N+1, M+1). RF data path redundancy is enabled by the integrated RF Switch
matrix, which supports dual redundancy groups.

The following sections provide a high-level overview of the downstream data path:

1. Data packets are received by the Cisco RFGW-10 UEQAM via either the 10GE or multiple 1GE

interfaces.

2. Data packets are received by the switch fabric on the Supervisor card (all external Ethernet ports

terminate at the Supervisor Switch fabric). The supervisor forwards data traffic to the line cards
based on the session information and IP address. For data traffic, the supervisor de-encapsulates
IP/LT2P DEPI traffic and for Video, the supervisor de-encapsulates based on the IP address/UDP
range information.

3. All data path traffic terminates at the specific RF line card (chassis slots 3:12). All cards in the

system are synchronous to the DTI system clock reference.

4. For DEPI traffic, the DS line card extracts L2TP header information, parses and processes DOCSIS

packets, re-stamps data with DOCSIS time stamps, and completes the J.83 FEC processing.

5. For Video traffic, the DS line card classifies the video packets, manages intra-QAM scheduling,

PCR re-stamping, PID re-mapping, and J.83/FEC encoding.

6. The J.83 FEC encoded data is forwarded to the upconverter module, which modulates, upconverts,

and forwards data downstream in MPEG-2/MPEG-4 encoding.

Cisco RFGW-10 IOS Software

The Cisco RFGW-10 UEQAM runs the Cisco IOS software, which is stored on the compact flash
memory disks that fit in the single compact flash memory slot on the front of the Supervisor Cards. The
compact flash can store a Cisco IOS image or the configuration file.

In addition to the flash memory disks, each Supervisor module contains onboard flash memory that
stores a boot loader. The loader executes following a system reset to reload and execute the Cisco IOS
software on the flash memory disks.

The Supervisor module also stores the system configuration in the onboard flash memory. The
configuration information read from the flash memory is buffered in the operational memory following
initialization, and is written to the flash memory device when the configuration is saved.

Each line card also contains an onboard flash memory that is used to store a boot loader, similar in
function to that used on the Supervisor card. However, the line card loader executes following a system
reset, line card reset, or line card insertion to reload and executes any code that must run on the line card.

Software images may also be stored on an external TFTP server. Based on the configuration, the proper
image might be downloaded from the TFTP server and executed.

The Cisco RFGW-10 UEQAM is installed in a standard 19-inch equipment or telco rack. A rack-mount
kit ships from the Cisco factory with each router. The rack-mount kit includes the hardware needed to
mount the router in a standard 19-inch equipment rack or telco-type rack. Mounting in 23-inch
equipment rack is possible with optional third-party mounting hardware.

The components in the front include the Supervisor Cards, RF line cards, and the front panel LCD. The
components on the rear include the Fan Assembly, RF Switch cards (coaxial terminations), TCC (DTI
Clock) cards, and the power supply modules.

All components (excluding the LCD) are hot-swappable and field replaceable. A fully configured system
will operate with a single DC PEM installed; the second PEM is required for power supply redundancy
and power load sharing.

Note Proper configuration of the DC power input requires that both Input 1 and Input 2 are connected to the

external power source and the GND connections are connected to the Earth GND. Input 1 and Input 2
on the DC PEMs are not redundant power inputs. If only one of the inputs is connected to the external
power, the Cisco RFGW-10 UEQAM will not power-on correctly.

Fan Assembly

The Cisco RFGW-10 UEQAM system uses a modular fan assembly to dissipate heat from the system
and control the temperature of the chassis system components (except the DC PEM, which contains its
own internal fan). The fan assembly is a multi-fan design that pulls ambient air from the lower front of
the chassis and exhausts air out of the rear top of the chassis. The fan assembly provides individual fan
control and failure monitoring, multiple thermistors to monitor exhaust air and a wide range of speed
control parameters based on the system and the environmental conditions. Inlet air monitoring is
communicated to the fan tray via the system software from the sensors on each of the RF line cards.

The fan tray module provides the following features:

• Online insertion and removal OIR support

• Failure monitoring of individual fans

• Backup temperature monitoring to control individual fan rotation per minute (RPM)

• Usage counter based on hours of operation (CLI-based)

• Front panel LED for alarm status indication

• Control and power circuit failure alarms

• On board multi-level fan speed control based on system temperature

The fan assembly draws air into the chassis and directs it across the internal system components. The
heated air exhausts out of the rear of the chassis as shown in Figure 1-4.

Figure 1-4 Cisco RFGW-10 Airflow

Chapter 1 Overview

The fan tray has four speed levels based on the operating control modes for the system. After power on,
the fan speed is set according to the Supervisor provided ambient average air temperature and the
configured speed control mode in the system configuration. The default control mode setting configures
the fans at maximum speed. The speed of the fans regulate to a slower speed when the fan controller
stabilizes to the ambient temperature and chassis temperature. After startup, it may take up to 30 seconds
for the fans to stabilize at the requested RPM.

Figure 1-5 and Figure 1-6 show the fan assembly module. The fan tray has a single LED indicator (FAN

OK) located in the center of the module. The FAN OK LED status indicators are defined in Ta ble 1 - 2:

DC PEMs

Note Each DC PEM has an earth ground connection and two DC power input connections (Input 1 and Input

Chapter 1 Overview

The Cisco RFGW-10 system is powered by redundant DC PEMs. An individual PEM is capable of
providing 4536 watts of total output. The redundant modules work as a 1:1 redundancy configuration
and support OIR (hot swapping). These modules do not support current sharing as they are non-isolated
PEMs, which are diode OR'd into two separate load zones.

Each PEM includes two 60A input lines that operate between –40VDC and –60VDC input voltages.
Proper configuration and operation requires that both DC inputs are properly wired. The PEM also
includes an earth ground connection (this is not power return) for grounding the chassis.

2). Both external DC inputs (Input 1 and Input 2) must be connected as shown in Figure 1-7. Input 1 and
Input 2 are individual power inputs. Both power inputs on the PEM must be wired to external power for
the Cisco RFGW-10 UEQAM to operate properly. If both inputs are not connected to external power, the
Cisco RFGW-10 UEQAM will not power on.

DC PEM features:

• Closed frame, NEBS-compliant module design

• Front-to-back airflow (exhaust air exits out of the rear of the chassis)

• Power input range: –48VDC to –60VDC

• 4536W power capacity

• Supports OIR (hot swap)

• Supports 1:1 redundancy (system can run with a single PEM)

• CLI interface support for status and configuration

• Remote shutdown feature

• Front panel LED status and alarm indicators

Note When both the DC PEMs are installed, both need to operate with the breaker switches and the OUTPUT

OK LED on. If one PEM is not operational, it is recommended that the PEM either be removed from the
system or the power input cables be removed to limit the power supply Conductive Emissions (FCC
conductive Emission Requirements).

Cisco RFGW-10 DS-48 Line Card

1-20

The Cisco RFGW-10 DS-48 line card is a QAM modulator and upconverter product designed to support
DOCSIS downstream data traffic (DEPI D-MPT) and video applications (VoD, SDV, and broadcast
video). The DS-48 card is similar to the traditional QAM solutions where the card receives encapsulated
data, de-packetizes/re-formats the packets, maps them to the output QAM channel, and performs QAM

Cisco RF Gateway 10 Hardware Installation Guide

OL-16264-04

Chapter 1 Overview

Cisco RFGW-10 Components

modulation and frequency upconversion. From a high level, the DS-48 line card receives Video and
DOCSIS data encapsulated over Ethernet and outputs analog QAM data to the subscriber devices (STB,
DOCSIS modems).

As a DOCSIS engine, the DS-48 line card supports DEPI D-MPT mode (future SW releases may support
PSP mode). DEPI is based on the L2TPv3 protocol, which includes a data plane and a control plane.
DEPI data plane traffic is terminated at the line card. The Cisco RFGW-10 Supervisor terminates DEPI
control and communicates the control to each line card in the system via the chassis IPC infrastructure.
DOCSIS timing information (10.24MHz synchronous DTI clock) is received by the line card from the
system TCC cards.

As a video engine, the DS-48 terminates video data path traffic forwarded from the Supervisor Engine
(video control plane traffic is terminated and processed by the system Supervisor). The DS-48
processing path classifies video packets, performs inter QAM processing, bitrate scheduling, program
muxing/scheduling, PID remapping, PCR re-stamping, and CC re-stamping.

A critical feature for the DS-48 line card is redundancy and high availability support. The line cards are
designed to detect and react to a wide range of faults and failures and respond with sub-second failover
to a dedicated protect card.

The DS-48 line card is designed to support a wide range of line card health conditions and initiate
failover events if considered catastrophic:

• QAM/upconverter HW failure. The line card monitors both the digital and RF data integrity. The

modules also provide a comprehensive alarm structure to the system CPU, which allows constant
monitoring of the UPX.

• Environmental alarms (temperature, voltage, frequency).

• Software kernel failures.

• Software module failure.

• DTI Clock/Timing failures (both internal and external).

• SFP failures.

The DS-48 line card has 12 physical RF ports, which support up to four QAMs per port. The number of
QAM outputs is configurable on a per port basis (meaning an individual port can support 1, 2, or 4 QAMs
as well as muting of individual QAMs within a QAM group). In stacked QAM mode, the QAMs are
stacked contiguously over a 24-MHz or 32-MHz band. The line card supports a downstream channel
frequency range of 88 MHz to 870 MHz.

The front panel includes two 1xGE ports and a single DVB-ASI interface (covers all video output
streams). The front panel connectors support both copper and fiber SFP modules. The front panel GE
ports are not processed directly by the line card, these are independent of the line card and route directly
to the Supervisor switch fabric. These ports do not become out of service if the line card crashes and a
failover to the redundant card occurs.

Line Card Hardware Installation Guide.

TCC/DTI Card

The Cisco RFGW-10 UEQAM supports two Timing, Communication, and Control (TCC) slots. The
TCC card acts as a secondary processor that controls the overall system clock generation and
distribution, DOCSIS timestamp synchronization, and system control of the Front Panel Display (FPD)
and the RF Switch cards.

The TCC card’s most critical function is distribution of the system clocking, in particular the DTI
interface. The TCC card is a DTI client interface. It supports dual DTI external input allowing DTI server
redundancy. Based on the DTI input information, the TCC card generates DOCSIS 10.24-MHz clock and
timestamp information to every line card in the chassis. All clocks and DOCSIS information are
redundant. When there is no external DTI clock, the TCC provides an internal DOCSIS DTI clock and
time stamp reference.

When two TCC cards are installed, they are configured as active and backup (redundant). If the TCC
card in the first slot is working at system power-up, it automatically becomes the active card and the TCC
card in the second slot becomes the backup card (typically Slot 13 boots as the primary TCC and Slot
14 as the secondary, but this is not mandatory).

OL-16264-04

Cisco RF Gateway 10 Hardware Installation Guide

1-23

Cisco RFGW-10 Components

In terms of the overall system high availability, the TCC cards work autonomously from the centralized
control mechanisms. Redundant TCC cards monitor each other’s priority information so that when the
active card fails, the active card role is transferred to the redundant backup card without loss of data.

The following is a summary of the TCC card’s functions and features:

• Generates and distributes 10.24 MHz clock references and 32-bit timestamp references to every

• Drives the LCD module used to display the system configuration and status information

• Proxy control mechanism (via supervisor cards) for the RF Switch Cards

• Front Panel LEDs providing Status and Alarm Indicators

RF Switch Card

The RF Switch provides RF data path redundancy at both the line card (slot) level and the RF port level
for bi-directional DOCSIS traffic upto 1.2 GHz. Additionally, the RF Switch cards are the coaxial cable
termination point for the Cisco RFGW-10.

Functionally the RF Switch card physically switches out a failed line card (port by port) at the RF data
path level. The card is capable of supporting (two) simultaneous RF line card failures. It is designed to
support dual N+1 redundancy groups (where N is a group of RF line cards associated with a single
“protect” card).

Cisco RFGW-10 Components

273441

There are 12 RF Switch cards per chassis providing 120 RF ports for the system (Note: the chassis
MUST include all 12 RF Switch cards for proper operation). Each Switch Card supports a single Cisco
UCH2 connector header; the UCH2 supports 10 MCX coaxial connections per card. The RF Switch card
is physically separate from the RF line cards slots allowing insertion or removal of the RF line cards
without disruption of the cable plant wiring.

The RF Switch Card is the central hardware component for chassis-level HA features. The card can be
configured and controlled via the system level CLI functionality. The RF Switch card is a hardware and
firmware based module (no operating software) that can be field upgraded via the chassis CLI.

The RF Switch Card faceplate includes a single LED, which provides very high level status for power
and functionality. The LED does not indicate a line card failover.

Site Planning

Site Power Guidelines

The Cisco RFGW-10 UEQAM has specific power and electrical wiring requirements. Adhering to these
requirements ensures reliable operation of the system. Follow these precautions and recommendations
when planning your site the Cisco RFGW-10 UEQAM:

• The redundant power option provides a second, identical power supply to ensure that power to the

chassis continues uninterrupted if one power supply fails or input power on one line fails.

• In systems configured with the redundant power option, connect each of the two DC PEMs to a

separate input power source. If you fail to do this, your system might be susceptible to total power
failure due to a fault in the external wiring or a tripped circuit breaker.

• To prevent a loss of input power, be sure the total maximum load on each circuit supplying the DC

PEM is within the current ratings of the wiring and breakers.

• Check the power at your site before installation and periodically after installation to ensure that you

are receiving clean power. Install a power conditioner if necessary.

• Provide proper grounding to avoid personal injury and damage to the equipment due to lightning

striking power lines or due to power surges. The chassis ground must be attached to a central office
or other interior ground system.

• The Cisco RFGW-10 should be connected to the DC main supplies, which are earthed within the

same building.

Caution This product requires short-circuit (overcurrent) protection, to be provided as part of the building

installation. Install only in accordance with national and local wiring regulations.

OL-16264-04

Note The Cisco RFGW-10 UEQAM installation must comply with all applicable codes and is approved for

use with copper conductors only. The ground bond fastening hardware should be of compatible material
and preclude loosening, deterioration, and electrochemical corrosion of hardware and joined material.
Attachment of the chassis ground to a central office or other interior ground system must be made with
an AWG #6 gauge wire, copper ground conductor at a minimum.

Chapter 2 Preparing Your Site for Installation

If wires exceed recommended distances, or if wires pass between buildings, give special consideration
to the effect of a lightning strike in your vicinity. The electromagnetic pulse caused by lightning or other
high-energy phenomena can easily couple enough energy into unshielded conductors to destroy
electronic devices. If you have had problems of this sort in the past, you may want to consult experts in
electrical surge suppression and shielding.

Asynchronous Terminal Connections

The Supervisor provides a console port to connect a terminal or computer for local console access. The
Supervisor also provides an auxiliary port to connect to a modem for remote dial-in console access.

Both ports have RJ-45 connectors, support RS-232 asynchronous data, and have distance
recommendations specified in the IEEE RS-232 standard.

Interference Considerations

When wires are run for any significant distance, there is a risk that stray signals will be induced on the
wires as interference. If interference signals are strong, they can cause data errors or damage to the
equipment.

The following sections describe sources of interference and how to minimize its effects on the
Cisco RFGW-10 UEQAM system.

Site Planning

Electromagnetic Interference

All equipment powered by AC current can propagate electrical energy that can cause electromagnetic
interference (EMI) and possibly affect the operation of other equipment. The typical sources of EMI are
equipment power cords and power service cables from electric utility companies.

Strong EMI can destroy the signal drivers and receivers in the Cisco RFGW-10 UEQAM and even create
an electrical hazard by causing power surges through power lines into installed equipment. These
problems are rare, but could be catastrophic.

To resolve these problems, you need specialized knowledge and equipment, which could consume
substantial time and money. However, you should ensure that you have a properly grounded and shielded
electrical environment, paying special attention to the need for electrical surge suppression.

Radio Frequency Interference

When electromagnetic fields act over a long distance, radio frequency interference (RFI) can be
propagated. Building wiring can often act as an antenna, receiving the RFI signals and creating more
EMI on the wiring.

If you use twisted-pair cable in your plant wiring with a good distribution of grounding conductors, the
plant wiring is unlikely to emit radio interference. If you exceed the recommended distances, use a
high-quality twisted-pair cable with one ground conductor for each data signal.

Lightning and AC Power Fault Interference

If signal wires exceed recommended cabling distances, or if signal wires pass between buildings, you
should consider the effect that a lightning strike in your vicinity might have on the Cisco RFGW-10
UEQAM.

Chapter 2 Preparing Your Site for Installation

EN 60950-1

IEC 60950-1

AS/NZS 60950.1

The electromagnetic pulse (EMP) generated by lightning or other high-energy phenomena can couple
enough energy into unshielded conductors to damage or destroy electronic equipment. If you have
previously experienced such problems, you should consult with RFI/EMI experts to ensure that you have
adequate electrical surge suppression and shielding of signal cables in your Cisco RFGW-10 UEQAM
operating environment.

Rack-Mounting and Location Guidelines

The Cisco RFGW-10 UEQAM is designed for standalone, two-post 19-inch rack-mount, four-post
19-inch rack-mount and closed cabinet systems with front and rear doors.

The sections that follow describe criteria for selecting a rack to mount the Cisco RFGW-10 UEQAM,
guidelines for placing the rack for reliable operation, and safety precautions to take to prevent bodily
injury when mounting a Cisco RFGW-10 UEQAM system in a rack.

Precautions for Rack-Mounting

The following rack-mount guidelines are provided to ensure your safety:

• Do not move large racks by yourself. Due to the height and weight of a rack, a minimum of two

people are required to accomplish this task.

• Ensure that the rack is level and stable before extending a component from the rack.

• Ensure that proper airflow is provided to components in the rack.

• Do not step or stand on any component or system when servicing other systems or components in a

rack.

• When mounting the Cisco RFGW-10 UEQAM in a partially filled rack, load the rack from the

bottom to the top with the heaviest component at the bottom of the rack.

2-12

• If the rack is provided with stabilizing devices, then install the stabilizers before mounting or

servicing the unit in the rack.

Cisco RF Gateway 10 Hardware Installation Guide

OL-16264-04

Chapter 2 Preparing Your Site for Installation

Rack Selection Guidelines

The Cisco RFGW-10 UEQAM can be mounted in most two-post or four-post, 19-inch equipment racks
that comply with the Electronics Industries Association (EIA) standard for equipment racks (EIA-310-D
19-inch). The rack must have at least two posts with mounting flanges to mount the chassis.

Caution When mounting a chassis in any type of rack equipment, make certain the inlet air to the chassis does

not exceed 104°F (40°C).

The distance between the center lines of the mounting holes on the two mounting posts must be 18.31
inches ± 0.06 inch (46.50 cm ± 0.15 cm). The rack-mounting hardware included with the chassis is
suitable for most 19-inch equipment racks.

We recommend that you mount the Cisco RFGW-10 UEQAM in an equipment rack that includes the
necessary rack-mounting hardware, which is suitable for most 19-inch equipment racks.

Consider installing the Cisco RFGW-10 UEQAM in a rack with the following features:

• NEBS-compliant, 19-inch (48.3 cm) wide rack.

• EIA or ETSI hole patterns in the mounting rails. Required mounting hardware is shipped with the

Cisco RFGW-10 UEQAM. If the rack that you plan to install the system in has metric-threaded rails,
you must provide your own metric mounting hardware.

Site Planning

• Perforated top and open bottom for ventilation to prevent overheating.

• Leveling feet for stability.

Equipment Rack Guidelines

The placement of the rack can affect personnel safety, system maintenance, and the system ability to
operate within the environmental characteristics described in Table 2 - 2. Choose a proper location for the
Cisco RFGW-10 UEQAM by following the guidelines below.

Locating for Safety

If the Cisco RFGW-10 UEQAM is the heaviest or the only piece of equipment in the rack, consider
installing it at or near the bottom to ensure that the rack center of gravity is as low as possible.

For additional information about the proper placement of electronic equipment, consult the document
GR-63-CORE, Network Equipment Building System (NEBS) Requirements: Physical Protection.

Locating for Easy Maintenance

Keep at least 3 feet of clear space in front and behind the rack. This space ensures that you can remove
the Cisco RFGW-10 UEQAM components and perform routine maintenance and upgrades easily.

Avoid installing the Cisco RFGW-10 UEQAM in a congested rack and consider how the routing of
cables from other pieces of equipment in the same rack could affect access to the routers cards.

The front and back of the chassis must remain unobstructed to ensure adequate airflow and prevent
overheating inside the chassis.

OL-16264-04

Cisco RF Gateway 10 Hardware Installation Guide

2-13

Site Planning

Allow the following clearances for normal system maintenance:

• At the back of the chassis for maintenance—To 4 ft (91.44 cm to 121.92 cm)

• At the back of the chassis for airflow obstructions—At least 4 inches (7.6 cm)

• In the front of the chassis for maintenance—3 to 4 ft (91.44 cm to 121.92 cm)

• In the front of the chassis for airflow obstructions—At least 4 inches (7.6 cm)

To avoid problems during installation and ongoing operation, follow these general precautions when you
plan the equipment locations and connections:

• Use the show environment all command regularly to check the internal system status. The

environmental monitor continually checks the interior chassis environment; it provides warnings for
high temperature and creates reports on any occurrences. If warning messages are displayed, take
immediate action to identify the cause and correct the problem.

• Keep the Cisco RFGW-10 UEQAM off of the floor and out of areas that collect dust.

• Follow ESD prevention procedures to avoid damage to equipment. Damage from static discharge

can cause immediate or intermittent equipment failure.

Locating for Proper Airflow

Chapter 2 Preparing Your Site for Installation

Ensure the location of the Cisco RFGW-10 UEQAM has enough airflow to keep the system operating
within the environmental characteristics and the air temperature is sufficient to compensate for the heat
dissipated by the system.

Avoid locating the Cisco RFGW-10 UEQAM in a location in which the chassis air intake vents could
draw in the exhaust air from adjacent equipment. Consider how the air flows through the Cisco
RFGW-10 UEQAM. The Cisco RFGW-10 UEQAM airflow direction is front to back with ambient air
drawn in from the venting located on the chassis front sides.

Preventing Electrostatic Discharge Damage

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, occurs when electronic cards or components are improperly
handled and can result in complete or intermittent failures. The Supervisors, and all line cards consist of
a printed circuit card that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding and
connectors are integral components of the carrier. Although the metal carrier helps to protect the cards
from ESD, use an antistatic strap each time you handle the modules. Handle the carriers by the edges
only; never touch the cards or connector pins.

Caution Always tighten the captive installation screws on all system components when you are installing them.

These screws prevent accidental removal of the module, provide proper grounding for the system, and
help to ensure that the bus connectors are properly seated in the backplane. Captive screws should be
torqued to 6-8 in-lbs to ensure proper grounding and mechanical support. Never use cordless or corded
drills to tighten screws, power screwdrivers and hand tools are acceptable.

Static electricity can harm delicate components inside your system. To prevent static damage, discharge
static electricity from your body before you touch any of your system components, such as an
microprocessor. As you continue to work on your system, periodically touch an unpainted metal surface
on the computer chassis.

Following are guidelines for preventing ESD damage:

• Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.

Before removing a card from the chassis, connect the equipment end of the strap to the ESD plug at
the bottom of the chassis below the power entry modules (see Figure 3-13, and Figure 3-14).

• Handle line cards by the faceplates and carrier edges only; avoid touching the card components or

any connector pins.

• When removing a card, place the removed module component-side-up on an antistatic surface or in

a static-shielding bag. If the module will be returned to the factory, immediately place it in a
static-shielding bag.

• Avoid contact between the modules and clothing. The wrist-strap protects the card from ESD

voltages on the body only; ESD voltages on clothing can still cause damage.

• When transporting a sensitive component, first place it an antistatic container or packaging.

• Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and

workbench pads.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be

between 1 and 10 megohms.

Electrical Safety

OL-16264-04

All system components are hot-swappable. They are designed to be removed and replaced while the

• Before beginning any procedures requiring access to the chassis interior, locate the emergency

power-off switch for the room in which you are working.

• Disconnect all power and external cables before installing or removing a chassis.

• Do not work alone when potentially hazardous conditions exist.

• Never assume that power has been disconnected from a circuit; always check.

• Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

Never install equipment that appears damaged.

• Carefully examine your work area for possible hazards such as moist floors, ungrounded power

extension cables, and missing safety grounds.

In addition, use the guidelines that follow when working with any equipment that is disconnected from
a power source but is still connected to telephone wiring or other network cabling.

• Never install telephone wiring during a lightning storm.

• Never install telephone jacks in wet locations unless the jack is specifically designed for wet

locations.

• Never touch un-insulated telephone wires or terminals unless the telephone line has been

disconnected at the network interface.

designed to support the weight of the unit.

Installation Methods

Rack-mounting is the preferred method of installation for the Cisco RFGW-10 UEQAM. You can mount
the chassis:

• Front mount or mid mount

• In a 19-inch wide (standard), four-post equipment rack or two-post, using the rack-mount brackets

in the accessory kit

Note The Cisco RFGW-10 UEQAM usually ships fully loaded. It is recommended that you remove the

components from the chassis to make the chassis lighter for your rack installation. It is recommended to
remove the two DC PEMs, the two Supervisor Cards, and the 10 Universal RF Line Cards.

Caution Before you proceed, read the instructions in the “Chassis-Lifting Guidelines” section on page 2-17.

Statement 1032

General Rack Installation Guidelines

When planning your rack installation, consider the following guidelines:

• The Cisco RFGW-10 UEQAM requires a minimum of 13 rack units (22.75 inches or 57.785 cm) of

vertical rack space. Measure the proposed rack location before mounting the chassis in the rack.

• Before using a particular rack, check for obstructions (such as a power strip) that could impair

rack-mount installation. If a power strip does impair a rack-mount installation, remove the power
strip before installing the chassis, and then replace it after the chassis is installed.

• Allow sufficient clearance around the rack for maintenance. If the rack is mobile, you can push it

back near a wall or cabinet for normal operation and pull it out for maintenance (installing or moving
cards, connecting cables, or replacing or upgrading components). Otherwise, allow 36 inches
(91.44 cm) of access to remove field-replaceable units.

• Maintain a minimum clearance of 4 inches (10.16 cm) on the front and the rear of the chassis for the

cooling air inlet and exhaust ports, respectively. Avoid placing the chassis in an overly congested
rack or directly next to another equipment rack; otherwise, the heated exhaust air from the other
equipment can enter the inlet air vents and cause a high temperature condition inside the router.

Caution To prevent chassis overheating, never install a Cisco RFGW-10 UEQAM in an enclosed room that is not

properly ventilated or air conditioned.

• Always install the heavier equipment in the lower half of the rack to maintain a low center of gravity

to prevent the rack from falling over.

Chapter 3 Cisco RFGW-10 UEQAM Installation

Rack-Mounting a Cisco RFGW-10 UEQAM

• Install and use the cable-management brackets included with the Cisco RFGW-10 UEQAM to keep

the cables organized and out of the way of the cards and processors. Ensure that the cables from the
other equipment already installed in the rack do not impair access to the cards or require you to
disconnect cables unnecessarily to perform equipment maintenance or upgrades.

• Install rack stabilizers (if available) before you mount the chassis.

• Provide an adequate chassis ground (earth) connection for your Cisco RFGW-10 UEQAM chassis.

In addition to the preceding guidelines, review the precautions for avoiding excessive temperature
conditions in the “Electrical Safety” section on page 2-15.

The Cisco RFGW-10 UEQAM can be installed in either front-mount or mid-mount configurations. The
chassis rack-mounting flanges must be secured directly to the chassis before lifting it into the rack.

Verifying Rack Dimensions

Before you install the chassis, measure the space between the vertical mounting flanges (rails) on your
equipment rack to verify that the rack conforms to the measurements shown in Figure 3-3.

Step 1 Mark and measure the distance between the two holes on the left and right mounting rails. The distance

should measure 18.31 inches ± 0.06 inches (46.5 cm ± 0.15 cm).

Note Measure the pairs of holes near the bottom, middle and top of the equipment rack to ensure that the rack

posts are parallel.

Step 2 Measure the space between the inner edges of the left front and right front mounting flanges on the

equipment rack.

The space must be at least 17.7 inches (45 cm) to accommodate the chassis, which is 17.25 inches
(43.8 cm) wide and fits between the mounting posts on the rack.

Installing the Chassis Installation Brackets

Each chassis is shipped with two chassis installation brackets in the accessory kit. These brackets are to
aid in installing a chassis into a 19-inch rack and used as a support base to vertically position and set the
chassis before the rack-mount screws are installed.

To install the chassis installation brackets into a rack, complete the following steps:

Step 1 Determine where in the rack you want the chassis to be mounted. If you are mounting more than one

chassis in the rack, then start from the bottom up or the center of the rack. Install the chassis installation
bracket where the chassis bottom will be positioned vertically in the rack.

Step 2 Secure the chassis installation bracket to the front rails with the rack-mount screws.

Step 3 If there is a second internal rack rail, which is not more than 20 inches from the front rail, you can

position the second installation bracket to act as a rear support for the chassis during installation.

Connecting DC-Input Power to Cisco RFGW-10 UEQAM

This section describes how to connect the DC power supply to the Cisco RFGW-10 UEQAM.

Before you begin, read these important notices:

• The color coding of the DC-input power supply leads depends on the color coding of the DC power

source at your site. Typically, green or green/yellow is used for ground (GND), black is used for
–48V on negative (–) terminal and red is used for RTN on the positive (+) terminal. Ensure that the
lead color coding you choose for the DC-input power supply matches the lead color coding used at
the DC power source.

3-22

Cisco RF Gateway 10 Hardware Installation Guide

OL-16264-04

Chapter 3 Cisco RFGW-10 UEQAM Installation

• For the DC input power cables, select the appropriate wire gauge based on the National Electrical

Code (NEC) and the local codes for 60-amp service at nominal DC input voltage (–48 VDC). Two
pairs of cable leads, source DC (–) and source DC return (+), are required for each power
distribution unit (PDU). These cables are available from any commercial cable vendor. All input
power cables for the chassis should have the same wire gauge and cable lengths should match within
10 percent of deviation.

Each DC input power cable is terminated at the PDU by a cable lug (included in the accessory kit).
The cable lugs must be dual-hole, and have a 90 degree tongue (reference Panduit LCD4-14AF-L).
They must be able to fit over M6 terminal studs at 0.625-inch (15.88-mm) centers.

Note The DC input power cables must be connected to the PDU terminal studs in the proper positive (+) and

negative (–) polarity. In some cases, the DC cable leads are labeled, which is a relatively safe indication
of the polarity. However, you must verify the polarity by measuring the voltage between the DC cable
leads. When making the measurement, the positive (+) lead and the negative (–) lead must always match
the (+) and (–) labels on the power distribution unit.

• An earth ground cable is required for each DC PDU. We recommend that you use at least 4-AWG

multi-strand copper wire. This wire is not available from Cisco; it is available from any commercial
cable vendor.

The ground wire cable lug (provided in the accessory kit) should be dual-hole (as shown in Figure 3-18),
90 degree tongue (reference Panduit LCD4-14AF-L), and able to fit over M6 terminal studs at 0.625 inch
(1.588 cm) centers.
