Cisco XR 12404 Router Installation Guide
OL-13830-02
The Cisco PRP-2 delivers all these functions with enhanced performance and
capabilities. It also delivers the following feature enhancements (depending on
the software version running):
•2 Ethernet management ports
•Hard-drive support (optional part)
•BITS input ports
•1 GB compact image Flash memory support (optional part)
•Memory scalability up to 4 GB
The PRP-2 communicates with the line cards either through the switch fabric or
through the MBus. The switch fabric connection is the main data path for routing
table distribution as well as for packets that are sent between the line cards and
the PRP-2. The MBus connection allows the PRP-2 to download a system
bootstrap image, collect or load diagnostic information, and perform general,
internal system maintenance operations.
The PRP-2 can be designated as either the Designated System Controller (DSC)
or the Secure Domain router (SDR).
The Designated System Controller (DSC) performs the following functions:
•Implements control plane operations for the chassis
•Monitors temperature and voltage
•Monitors line cards
•On boot up, the first card to become active is designated as the DSC.
The Secure Domain Router (SDR) controls domain security features independent
of any other SDRs on the network.

Route Processor
Performance Route Processor Overview
The performance route processor (PRP) uses a Motorola PowerPC 7450 CPU that
runs at an external bus clock speed of 133 MHz and has an internal clock speed
of 667 MHz.
Figure 1-2 identifies the slots, ports, and LEDs on the PRP front panel.
Figure 1-2 Performance Route Processor Front Panel
PRP PCMCIA Card Slots and Status LEDs
Two PCMCIA card slots (slot 0 and slot 1) provide the PRP with additional flash
memory capacity. All combinations of different flash devices are supported by the
PRP. You can use ATA flash disks, Type 1 or Type 2 linear flash memory cards,
or a combination of the two.
Note The PRP only supports +5.2 VDC flash memory devices. It does not support
+3.3 VDC PCMCIA devices.
Status LEDs (Slot-0 / Slot-1) indicate when the flash memory card in that slot is
accessed (see Figure 1-2). Each slot has an eject button (located behind the cover)
to remove a flash card from the slot.

PRP Ethernet Ports and Status LEDs
The PRP has two 8-pin media-dependent interface (MDI) RJ-45 ports for either
IEEE 802.3 10BASE-T (10 Mbps) or IEEE 802.3u 100BASE-TX (100 Mbps)
Ethernet connections. These ports are labeled ETH 0 and ETH 1.
The transmission speed of the Ethernet port is not user-configurable. You set the
speed through an autosensing scheme on the PRP which is determined by the
network that the Ethernet port is connected to. However, even at an autosensed
data transmission rate of 100 Mbps, the Ethernet port can only provide a usable
bandwidth of substantially less than 100 Mbps. You can expect a maximum usable
bandwidth of approximately 20 Mbps when using an Ethernet connection.
The following LEDs on the front panel indicate traffic status and port selection
(Figure 1-3):
•LINK, EN, TX, RX—Indicate link activity (LINK), port enabled (EN), data
transmission (TX), and data reception (RX).
•PRIMARY—Indicates which Ethernet port is selected (ETH 0 or ETH 1).
Note Because both ports are supported on the PRP, ETH 0 is always on. ETH 1
lights when it is selected.

Route Processor
PRP Auxiliary and Console Ports
The auxiliary and console ports on the PRP are EIA/TIA-232 (also known as
RS-232) asynchronous serial ports. These ports connect external devices to
monitor and manage the system.
•The auxiliary port—A (male) plug that provides a data terminal equipment
(DTE) interface. The auxiliary port supports flow control and is often used to
connect a modem, a channel service unit (CSU), or other optional equipment
for Telnet management.
•The console port—A (female) receptacle that provides a data
circuit-terminating equipment (DCE) interface for connecting a console
terminal.
PRP Reset Switch
Access to the (soft) reset switch is through a small opening in the PRP front panel
(see Figure 1-2). To press the switch, insert a paper clip or similar small pointed
object into the opening.
Caution The reset switch is not a mechanism for resetting the PRP and reloading the
Cisco IOS image. It is intended for software development use only. To prevent
system problems or loss of data, use the reset switch only on the advice of Cisco
service personnel.
Pressing the reset switch causes a nonmaskable interrupt (NMI) and places the
PRP in ROM monitor mode. When the PRP enters ROM monitor mode, its
behavior depends on the setting of the PRP software configuration register. For
example, if the boot field of the software configuration register is set to:
•0x0—The PRP remains at the ROM monitor prompt (rommon>) and waits for
a user command to boot the system manually.
•0x1—The system automatically boots the first Cisco IOS image found in
flash memory on the PRP.

Route Processor
PRP SDRAM
The PRP uses Error Checking and Correction (ECC) Synchronized Dynamic
Random Access Memory (SDRAM) to store routing tables, protocols, network
accounting applications, and to run Cisco IOS software.
Table 1-2 lists the DRAM configurations for the PRP. If you are using:
•One DIMM—Bank 1 (U15) must be populated first.
•Two DIMMs—You cannot mix memory sizes; both banks must contain the
same size DIMM.
Caution DRAM DIMMs must be 3.3-volt, 60-nanosecond devices only. Do not attempt to
install other devices in the DIMM sockets. To prevent memory problems, use the
Cisco approved memory products listed in Table 1-2.
PRP SRAM
Static Random Access Memory (SRAM) provides 2 MB of secondary CPU cache
memory. Its principal function is to act as a staging area for routing table updates,
and for information sent to and received from the line cards. SRAM is not
user-configurable and cannot be upgraded in the field.

PRP NVRAM
Non-volatile Random Access Memory (NVRAM) provides 2 MB of memory for
system configuration files, software register settings, and environmental
monitoring logs. Built-in lithium batteries retain the contents of NVRAM for a
minimum of 5 years. NVRAM is not user configurable and cannot be upgraded in
the field.
PRP Flash Memory
Use flash memory to store multiple Cisco IOS XR software and microcode
images that you can use to operate the router. You can download new images to
flash memory over the network (or from a local server) to replace an existing
image, or to add it as an additional image. The router can be booted (manually or
automatically) from any of the stored images in flash memory.
Flash memory also functions as a Trivial File Transfer Protocol (TFTP) server to
allow other servers to boot remotely from the stored images, or to copy them into
their own flash memory.
The system uses two types of flash memory:
•Onboard flash memory (called bootflash)—Contains the Cisco IOS boot
image
•Flash memory disks (or cards)—Contain the Cisco IOS software image
Table 1-3 lists supported flash disk sizes and Cisco part numbers.

–
The Alarm output function consists of a group of LEDs and their
associated drivers connected to an output port on the alarm MBus
module. As directed by the software on the route processor, the alarm
MBus module on the CSF card activates specific LEDs. The software
which drives these LEDs divides them into three levels, Critical, Major,
and Minor. The classification of a critical, major, or minor alarm is
determined by Cisco IOS XR software running on the route processor.
Each of the three LEDs is a dual LED (for failure redundancy).
–
The OK/Fail pair of LEDs indicate the status of the alarm MBus:
Green indicates that the alarm MBus module is operating properly.
Amber Fail indicates that the alarm MBus has detected an error in itself
or with the MBus module.
Power Source Monitoring
The alarm MBus monitors the power supply and signals when there is a condition
outside the normal range of operation.
•Power source voltage is not being provided to a component
•A fault exist in the power source or PEM
•A voltage monitor signal is outside the allowable range
•The current monitor signal is outside the allowable range

Power Entry Modules
Switch Fabric Functionality
Switch fabric circuitry provides up to 40 Gbps (full duplex) of synchronized speed
interconnections that carries user traffic between line cards or between the route
processor and the line cards.
Clock and Scheduler Functionality
The fabric card generates and distributes system-wide clock and cell time
synchronization signaling. System clock generation is delivered to the system
through the backplane and local clock functions are derived from the system
clock.
•System Clock—The system clock synchronizes data transfers between line
cards or between the route processor and a line card through the CSF. The
system clock signal is sent to all line cards and the route processor.
•Scheduler—The scheduler handles requests from the line cards for access to
the CSF. When the scheduler receives a request from a line card for CSF
access, the scheduler determines when to allow the line card access to the
CSF.
Power Entry Modules
The Cisco XR 12404 router chassis supports two hot swappable AC or DC PEMs.
The router must be populated with 2 PEMs to meet EMI standards.
Caution Do not mix PEM types in the router. PEMs must be the same type; either both
AC PEMs, or both DC PEMs and PDUs.

The status LEDs on the DC PEM provide information about the current
operational status of the power supply. Table 1-5 summarizes the function of these
indicators.
Power Distribution
The backplane distributes power through the Cisco XR 12404 router and to all
cards in the card cage. The PEM converts AC power source into –48 VDC. When
directed by the route processor or by MBus software, the MBus module turns on
the DC-DC converter; the –48 VDC is converted into +2.5 VDC, +3.3 VDC and
+5 VDC for all internal voltages required by the cards.
Power for the fan tray assembly is supplied directly from the backplane. An
internal fan tray assembly controller card converts –48 VDC into DC voltage that
powers the fans.
Fan Tray Assembly
The Cisco XR 12404 router is equipped with a fan tray assembly located at the
side of the chassis. The fan tray assembly maintains acceptable operating
temperatures for the internal components by drawing cooling air across the card
cage.

Cisco XR 12404 Router Installation Guide
OL-13830-02
Maintenance Bus
The Cisco XR 12404 router maintenance bus and MBus modules manage all of
the maintenance functions of the system. The MBus consists of two separate
busses (providing MBus redundancy). Each MBus is linked to all of the following.
•Line cards
•Route Processor
•CSF card
The MBus module located on each component, communicates over the MBus and
is powered by +5 VDC directly from the fabric card. The MBus performs the
functions of power-on/off control for each component, component (device)
discovery, code download, diagnostics, and environmental monitoring and
alarms.
Power-On/Off Control
Each MBus module directly controls the DC-to-DC converters on the component
it is mounted on based on commands the component receives from its on-board
EPROM and from the route processor. Each MBus module is tied directly to
+5 VDC from the consolidated fabric card.
When power is applied to the Cisco XR 12404 router, all MBus modules
immediately power on. The MBus modules on the route processor and CSF card
immediately turn on the DC-to-DC converter, powering up the respective card.
The line card MBus module waits to power on the line card until it receives a
command from the route processor.
Component Discovery
The route processor can determine the system configuration using the MBus. A
message is sent from the route processor over the MBus requesting all installed
devices to identify themselves. The response back provides component type, line
card slot number, and CSF card slot number.

Chapter 1 Cisco XR 12404 Router Overview
Maintenance Bus
Code Download
A portion of the line card operating software can be downloaded from the route
processor to the line card over the MBus. Because the MBus is relatively slow
compared to the CSF, only enough code is downloaded to the line card for it to
access the CSF and complete the download process.
Diagnostics
The diagnostic software image is downloaded from the route processor to the line
card during the test sequence.
Environmental Monitoring and Alarms
The MBus module on each component monitors that component’s environment as
follows.
•Line cards and the route processor are monitored for temperature by two
temperature sensors mounted on each card. The MBus module makes voltage
monitoring through software; for example the +2.5 VDC, +3.3 VDC, and
+5 VDC DC-to-DC converters.
•The CSF card is monitored for temperature by two temperature sensors
mounted on the card. The MBus module performs voltage monitoring through
software (for example, the +2.5 VDC and +3.3 VDC).
•Voltage monitoring the for +5 VDC, for example; is made by the alarm MBus
module on the CSF card.
•Environmental monitoring includes voltage and current monitoring,
temperature monitoring, and sensing for fan power and RPM.

Safety with Electricity
Most Cisco XR 12404 Router field replaceable units (FRUs) support online
insertion and removal (OIR), which means an FRU is hot-swappable and can be
removed and replaced while the system is operating without presenting an
electrical hazard or damage to the system.
Installation Site Requirements
This section provides site requirement guidelines that you must consider before
installing the Cisco XR 12404 Router.
Rack-Mounting and Ventilation Guidelines
Before installing the Cisco XR 12404 Router in a rack, consider the following
general rack-mounting guidelines.
As you face the rear of the chassis, the fan tray assembly is located on the right
side. Air flow to the air filter and fan tray assembly should not be blocked.
Note Warm air exhaust at the side of the chassis through the fan tray. Allow sufficient
air flow by maintaining 6 inches (15.24 CM) of clearance at both the inlet and
openings on the chassis.
•A ventilation system that is too powerful in an enclosed rack can also prevent
cooling by creating negative air pressure around the chassis and redirecting
the air away from the air intake vent. If necessary, operate the router with the
rack door open or in an open rack.
•The correct use of baffles inside an enclosed rack can assist in cooling the
router.
•Equipment located near the bottom of the rack can generate excessive heat
that is drawn upward and into the intake ports of equipment above, leading to
possible overheat conditions.

Rack Mounting Clearance
The rack-mounting hardware included with the Cisco XR 12404 Router is suitable
for most 19 inch equipment racks.
The following are rack-mounting guidelines for the Cisco XR 12404 Router.
•If you use a standard 19 inch racks be sure that the rack is bolted to the floor.
The chassis mounts to the two rack posts, and the rest of the chassis is
cantilevered off of the posts.
•Ensure that the weight of the Cisco XR 12404 Router does not make the rack
unstable.
•Some racks are secured to ceiling brackets, if necessary, because of the
weight of the equipment in the rack. Make sure that the rack you are installing
the Cisco XR 12404 Router in is secured.
•For the enhanced model of the Cisco XR 12404 Router, the mounting rails on
a 4-post rack must be recessed no more than 1.5 inches for the front door to
fully open and close and to provide adequate room for cable routing.
Multiple Routers in a Rack
One of the unique features of the Cisco XR 12404 Router is its size. Up to 8 Cisco
XR 12404 Routers can fit in a standard 19 inch equipment rack. When placing
multiple routers in a rack, ensure there is sufficient ventilation to accommodate
the router.
The heated exhaust air from other equipment can enter the inlet air vents and
cause an overtemperature condition inside the router.
•Install and use the line card brackets and chassis cable-management bracket
included with the router to keep cables organized and out of the way of line
cards.
•Ensure that cables from other equipment do not interfere with access to the
card cage, or require you to disconnect cables unnecessarily to perform
equipment maintenance or upgrades.
•When mounting the router in a four-post type rack, be sure to use all of the
screws provided to secure the chassis to the rack posts.

Environmental Guidelines
This section offers guidelines for operating your Cisco XR 12404 Router in
various environments; airflow, temperature and humidity, power source, AC and
DC powered routers, grounding connections and site wiring. To assure normal
operation and avoid maintenance difficulty, plan and prepare your site before you
install the router.
Airflow
The Cisco XR 12404 Router air circulation system consists of 1 fan tray assembly
mounted at the side of the chassis. The fan tray assembly maintains acceptable
operating temperatures for the internal components by drawing cooling air in
through a replaceable air filter, located on the right side of the chassis.
Air circulates through the card cage, and exhausts at the side of the chassis
(Figure 2-4).
•Allow sufficient air flow by maintaining 6 inches (15.24 cm) of clearance at
both the inlet and exhaust openings on the chassis.
•The site should be as dust-free as possible. Dusty environments can clog the
air filter, reducing the cooling airflow through the system. This can cause an
over temperature condition in the router.
Under extreme environment conditions, the environmental monitoring system
will shut down the power to protect the system components.

Chapter 2 Preparing for Installation
Installation Site Requirements
Power Connection Guidelines
The Cisco XR 12404 Router requires an AC PEM or a combination DC PDU and
DC PEM. Site requirements differ depending on the type of power source voltage.
We recommend you follow these precautions and recommendations when
planning power source connections to your router.
•Check the power at your site before installation and periodically after
installation to ensure that you are receiving clean power from the power
source.
•If necessary, install a power conditioner.
•Install proper grounding, or use the proper grounding receptacle located on
the side of the chassis, to avoid damage from lightning and power surges.
AC-Powered Routers
A Cisco XR 12404 Router configured with two AC PEMs, are shipped with a
three-wire electrical grounding-type plug that will only fit into a grounding-type
power outlet. This is a safety feature. The equipment grounding should be in
accordance with local and national electrical codes.
At sites where the Cisco XR 12404 Router operates with AC PEMs, observe the
following guidelines (Figure 2-3):
•A power factor corrector (PFC) allows the PEM to accept AC power source
voltage from an AC power source operating between 100 to 120 VAC,
15–Amp service in North America; and a range of 185 to 264 VAC, 10–Amp
service, in an international environment.
•All AC PEM power cords measure 14 feet (4.3 meters).
•Provide a dedicated power source for each PEM installed in the router.
•Install an uninterruptable power source where possible.
Caution Use the North American plug L6-20 20A only on 240 volt systems.

Figure 2-5 Cisco XR 12404 Router AC Power Plugs
Power Connection Guidelines for DC-Powered Routers
When the Cisco XR 12404 Router operates with a DC PDU, observe these
guidelines:
•A Cisco XR 12404 Router configured with a DC PDU and DC-input PEMs has
a maximum power rating of 35A per power module and requires a dedicated DC
power source to support this maximum current. The facility DC source circuit
breaker protection needs to comply with safety local codes and regulations.
This circuit breaker protects against short-circuit and overcurrent faults in
accordance with United States National Electrical Code NFPA 70 (United
States), Canadian Electrical Code, part I, CSA C22.1 (Canada), and IEC 364
(other countries).
•DC power cable leads should be #6 American Wiring Gauge (AWG)
high-strand-count wire.
•Provide a dedicated power source for each power entry module installed in
the router.

Installation Site Requirements
•Install an uninterruptable power source where possible.
Grounding Connections
Before you connect power or turn on your Cisco XR 12404 Router, you must
provide an adequate system ground for the router. The equipment grounding
should be in accordance with local and national electrical codes.
For installations other than in a network equipment building system (NEBS)
environment, you may chose to rely on the safety earth ground connection
supplied via the International Electrotechnical Commission (IEC) 320 inlets for
AC-powered units and the main terminal block ground connection for
DC-powered units.
Site Wiring
This section offers site wiring guidelines for setting up the plant wiring and
cabling at your site. When planning the location of the new system, consider the
following:
•Electromagnetic interference (EMI)
•Distance limitations for signaling and unshielded conductors
Electromagnetic Interference
Electromagnetic interference can occur between the signal on the wires and
external or ambient EMI fields when the wires are run for any significant distance.
This fact has two implications for the construction of plant wiring.
•Bad wiring practice can result in radio interference emanating from the plant
wiring.
Warning
Strong EMI, especially when it is caused by lightning or radio transmitters, can
destroy the signal drivers and receivers in the Cisco XR 12404 Router, and can
create an electrical hazard by conducting power surges through lines and may
cause damage to the equipment.

Chapter 2 Preparing for Installation
Unpacking and Repacking the Cisco XR 12404 Router
2-16
Cisco XR 12404 Router Installation Guide
OL-13830-02
Note To predict and remedy strong EMI, you may need to consult experts in
radio frequency interference (RFI).
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 when applicable.
Distance Limitations
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 (EMP) 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.
Most data centers cannot resolve the infrequent but potentially catastrophic
problems just described without pulse meters and other special equipment. These
problems can cost a great deal of time to identify and resolve, so take precautions
by providing a properly grounded and shielded environment, with special
attention to issues of electrical surge suppression.
Unpacking and Repacking the Cisco XR 12404 Router
The shipping package for Cisco XR 12000 Series Routers is engineered to reduce
the potential of product damage associated with routine material handling

Installing the Chassis on a Tabletop or Flat Surface
Use the following procedure to install the Cisco XR 12404 Router on a tabletop
or other stable flat surface.
Step 1 Move the router as close to the installation location as possible.
Step 2 With one person positioned at the front and rear of the chassis, lift the chassis off
of the pallet and position the chassis on the flat surface.
Step 3 Secure the chassis to the flat surface to ensure it does not fall off.
You can use the same mounting hardware that secured your router to the shipping
pallet to secure the chassis to the flat surface.
Supplemental Bonding and Grounding Connections
Before you connect power or turn on your Cisco XR 12404 Router, you must
provide an adequate system ground for the router. The equipment grounding
should be in accordance with local and national electrical codes.
If you are not installing the Cisco XR 12404 Router in a NEBS environment, you
can choose to bypass these guidelines and rely on the safety earth ground
connection supplied via the 5-15 15A North American plug to the AC-powered
PEMs, and the main terminal block ground connection for DC-powered PEMs.
•On Cisco XR 12404 Routers configured for AC-input operation, the AC PDU
is equipped with a three-wire electrical grounding-type connector that accept
three-wire, grounding-type AC power cords such as the power cords shipped
with the router. This is a safety feature.

•On Cisco XR 12404 Routers configured for DC-input operation, the DC PDU
is equipped with a DC power connector block with wire-connection terminals
for connecting the negative lead (top terminal), the positive lead (middle
terminal), and the ground lead (bottom terminal). This is a safety feature.
Note Cisco XR 12404 Router grounding architecture conforms to the DC-I
(DC-isolated) method of grounding as described in Telcordia
GR-1089-CORE. A DC-I architecture means that there is no connection
between the DC return terminal and the frame ground. DC return and
frame ground are isolated from one another at the router.
If the router is installed in a NEBS environment, we strongly recommend that you
connect the central office ground system or interior equipment grounding system
to the supplemental bonding and grounding point on the router chassis. This
grounding point consists of threaded inserts is located on the side of the chassis
near the back of the chassis (see Figure 3-3). It is also referred to as the NEBS
bonding and grounding receptacle, and is intended to satisfy the Telcordia NEBS
requirements for supplemental bonding and grounding connections.

Caution Carefully adjust the interface cable in the RP or line card cable-management
bracket to prevent any kinks or sharp bends in the interface cable. Kinks and sharp
bends can destroy or degrade the ability of the optical fiber to propagate the
signal-encoded beam of light accurately from one end of the cable to the other.
Also, allow adequate strain relief in the interface cable.
Step 3 Route the cable to the chassis cable-management bracket mounted to the left side
of the chassis (Figure 3-7).
•Use the screws packaged with the chassis cable management bracket kit.

Connecting to the Console Port and Auxiliary Ports
This section provides the information to connect a console to the router. Both Data
Set Ready (DSR) and Data Carrier Detect (DCD) signals are active when the
system is running. The console port does not support modem control or hardware
flow control. The console port requires a straight-through EIA/TIA-232 cable.
The system console port on the PRP is a DCE RJ-45 receptacle for connecting a
data terminal, which you must configure. The console port is labeled Console, as
shown in Figure 3-8.
Note To comply with Telcordia GR-1089 NEBS standard for electromagnetic
compatibility and safety, connect all console, auxiliary, Ethernet, and BITS
interfaces only to intrabuilding or non-exposed wiring or cabling. The
intrabuilding cable must be shielded and the shield must be grounded at both ends.
Check your terminal’s documentation to determine the baud rate of the terminal
you plan to use. If your documentation does not specify settings use the following
terminal settings:
1. Baud to 9600
2. Data bits to 8
3. Parity to no parity
4. Stop bits to 2
The console port requires a straight-through RJ-45 cable.

The software configuration register is set to 0x0102, which causes the router to
boot automatically from the Cisco IOS XR software image stored on the Flash
memory card.
•The Flash memory card that shipped with your system is installed in the
bottom slot, PCMCIA slot 0 of the RP (Figure 3-9).
Figure 3-9 Flash Memory Card Slots
Ensure that a console terminal is connected to the RP console port and turned on,
or that you have a remote login to the router from another device through a telnet
session.
Connecting the PRP to an Ethernet Network
The PRP includes two 10/100 Mbps Ethernet ports, each using an 8-pin RJ-45
receptacle for either IEEE 802.3 10BASE-T (10 Mbps) or IEEE 802.3u
100BASE-TX (100 Mbps) connections. The transmission speed of the Ethernet
ports is auto-sensing by default and is user configurable.
To connect cables to the PRP Ethernet interfaces (ports labeled ETH0 and ETH1),
attach the Category 5 UTP cable directly to a RJ-45 receptacle on the PRP.
Note The Ethernet interfaces on the PRP are end-station devices, not repeaters;
therefore, you must connect an Ethernet interface to a repeater or hub.

RJ-45 cables are not available from Cisco Systems, but are available from outside
commercial cable vendors.
Note Only connect cables that comply with EIA/TIA-568 standards. See Table 3-4 and
Table 3-5 for cable recommendations and specifications.
Note To comply with Telcordia GR-1089 NEBS standard for electromagnetic
compatibility and safety, connect all console, auxiliary, and Ethernet interfaces
only to intrabuilding or non-exposed wiring or cabling. The intrabuilding cable
must be shielded and the shield must be grounded at both ends.
Caution The Ethernet ports are primarily used as a Telnet port into the Cisco XR 12000
Series Router, and for booting or accessing Cisco IOS XR software images over
a network to which an Ethernet port is directly connected. Cisco Express
Forwarding (CEF) functions are switched off by default for security reasons.
Cisco strongly cautions you to consider the security implications of switching on
CEF routing functions on these ports.
Figure 3-10 is an example of the functionality of an Ethernet port. In this example,
you cannot access Network 2.0.0.0 through the Ethernet port (ETH0) on the PRP
in router A; you can only access the hosts and router C, which are in Network
1.0.0.0 (see dotted arrows in Figure 3-10).
To access Network 2.0.0.0 from router A, you must use an interface port on one
of your line cards (in this example, a Packet-over-SONET (POS) line card in
router A) to go through router B, through router C, and into Network 2.0.0.0 (see
solid arrows in Figure 3-10).

Step 6 Connect the other end of the AC power cord to the AC power source outlet.
Note We recommend attaching each AC PEM to an independent power source
for full redundancy. We also recommend that you use an uninterruptable
power source (UPS) to protect against power failures at your site.
Note When operating your router on an AC power source, both PEM bays must
have all AC PEMs installed to ensure compliance with regulatory EMI
standards.
Connecting to a DC Power Source
Each DC PDU should be connected to separate DC sources using six threaded
terminals. Two terminals for negative (source DC), two terminals for positive
(source DC return), and two terminals for ground. The DC power cable leads
should be 6 American Wiring Gauge (AWG) high strand count wire. The PEM
accepts DC power source voltage from a dedicated 35–Amp service DC power
source operating between -48 to -60 VDC.
Warning
Power to your router must be Off and all cables disconnected before you install
the DC power assembly. The DC PDU and DC PEM when connected, is not a
hot-swappable field replaceable unit.
Note We recommend each DC PDU be connected to an independent power source for
full redundancy. We also recommend that you use an uninterruptable power
source (UPS) to protect against power failures at your site.
Caution The DC PEM and DC PDU assembly weighs 14.0 pounds (6.35 kg.). Use two
hands when handling the power supply.

External Network Interface
Step 4 On the console terminal, verify that the console displays the system banner and
that the system and all interfaces initialize successfully.
If the router does not power on, or if any interfaces do not initialize properly, see
Chapter 4, “Troubleshooting the Installation,”. If you are still unable to resolve
the problem, contact your Cisco service representative for assistance.
External Network Interface
After configuration, the RP and line cards can communicate with external
networks.
You do not need to configure the network interfaces immediately, but you cannot
connect to a network until you configure the interfaces for operation in your
networking environment.
Note The interface-specific LEDs on the line cards go on when the line card interfaces
are configured.
To verify correct operation of each line card interface, complete the first-time
setup procedures and configuration, then check the status of the interfaces against
the LED descriptions in the configuration notes for each line card.
If the system does not complete each of the boot process steps, go to “Chapter 4,
“Troubleshooting the Installation.”
Manually Booting the System
If your router does not find a valid system configuration image, or if you interrupt
the boot sequence, the system might enter read-only memory (ROM) monitor
mode and display the ROM monitor prompt (rommon>). From ROM monitor
mode, you have access to a number of commands to locate and boot a valid system
image.

properly seated in the backplane. Although an overtemperature condition is
unlikely at initial startup, the environmental monitoring functions are included
here because they also monitor internal voltages.
When you start up the router for the first time, you should observe the startup
sequence. The normal startup sequence is as follows:
•Each card in the system has an MBus module and at least one DC-DC
converter. Each MBus module controls the DC-DC converter. The MBus
module receives +5 VDC directly from the power supplies through the
backplane. When the power supply is powered on, each MBus module boots
from an onboard electrically erasable programmable read-only memory
(EEPROM) device. Each MBus module processor reads a set of identification
pins on the card to the backplane connector telling the MBus module
processor what kind of card it is mounted on, which in turn, determines how
the MBus module will function.
•The consolidated switch fabric (CSF) containing the system clock,
immediately powers up.
•The MBus module on the RP monitors the progress of the clock and scheduler
card power on. When the CSF has powered up, the MBus module on the RP
turns on its DC-DC converter powering up the RP.
•The RP sends instructions to each line card to power up. Each line card
processor begins to perform its own boot process and notifies the RP when
the boot process is complete through its MBus module.
•As the boot process progresses for each card, the status of the card is shown
on the alphanumeric LED displays. The left display is powered by the DC-DC
converter on the card; the right display is powered by the DC voltage that
powers the MBus module.
By checking the state of the LEDs on the power supplies and the alphanumeric
displays on the RP and line cards, you can determine when and where the system
failed in the startup sequence.

Identifying Startup Problems
Using the System LEDs to Troubleshoot
You can determine when and where the system failed in the startup sequence by
checking the state of the LEDs on the power modules and line cards, and on the
alphanumeric displays on the RP.
You should observe the following when you power on the router:
•INPUT OK LEDs—These LEDs should light immediately; they should
remain on as long as the system is receiving power from the power source and
the power switch is in the on position.
The LEDs indicate the status of the PEM and internal DC voltages. If either
LED does not light, or if they shut off while the power switch is on, there
could be a problem with either the power source, the internal DC voltage used
to power internal components, or the cooling subsystem.
The LEDs remain on when all of the following conditions are met:
–
AC PEMs: The AC power source voltage is operating between
100-120 VAC and is using 15-Amp service for North America, or is
operating between 185-264 VAC and is using 10-Amp service in an
international environment.
–
DC PEMs: The DC power source is supplying power to the PEMs and the
power switch is in the on position.
Note The amber OUTPUT FAIL LED is normally off, but lights if the
PEM detects a fault.
–
The power supplies are providing –48 VDC to internal components.

–
All internal DC voltages are within tolerance.
If the AC power source or any of the internal DC voltages exceed
allowable tolerances, the OUTPUT OK LED shuts off, or will shut off
shortly after you turn on the power. Because both the RP (which uses
+2.5, +3.3 and +5 VDC), and the fan tray assembly (which uses –48
VDC) are required for operation, a problem with any of the internal DC
lines can prevent the system from starting up or continuing operation.
For example, if there is a problem with the –48 VDC line that supplies
the fan tray, the system powers up, but will also recognize that the fans
are not operating. The system will initiate a fan failure shutdown
sequence, display the appropriate warning messages, and then shut down
after two minutes.
If there is a problem with any of the other DC lines, the RP will not be
able to initialize the system software, so the system might attempt to start
up and fail during the boot sequence.
•The fan tray immediately begins operating.
•The alphanumeric LED displays on the RP indicate the following:
–
The left display indicates which RP software component is running.
–
The right display indicates the phase of the boot process that is currently
occurring.

Problem-Solving with Subsystems
Problem-Solving with Subsystems
The key to solving router problems is to isolate the problem to a specific
subsystem. The first step in solving startup problems is to compare what the
system is doing to what it should be doing. Because a startup problem is usually
attributable to a single component, it is more efficient to first isolate the problem
to a subsystem rather than trying to troubleshoot each component in the system.
For troubleshooting purposes, the Cisco XR 12404 router consists of the
following subsystems:
•Power subsystem—Includes the following components:
–
AC-input power supplies or DC-input power entry modules (PEMs). The
Cisco XR 12404 router can be configured for source AC or source DC
power (you can not mix AC and DC power).
–
Chassis backplane power distribution. The –48 VDC power from the
power supplies is transferred to the chassis backplane, which distributes
–48 VDC power to the cards in the card cages through the backplane
connectors.
–
DC-DC converters. Each card in the router is equipped with DC-to-DC
converters. These converters are controlled by the MBus module on each
card. The DC-to-DC converters take –48 VDC and convert it into the
voltages required by the card circuitry.
•Processor subsystem—The processor subsystem includes the RP and all line
cards. The RP downloads a copy of the Cisco IOS XR image to each line card
processor. The system uses alphanumeric LED displays to display status and
error messages, which can help in troubleshooting.
•Cooling subsystem—The cooling subsystem is comprised of one fan tray
assembly and one air filter. The fan tray assembly and air filter are
hot swappable, and can be replaced while the system is running.
Caution Replace the fan tray assembly within 2 minutes of removing it from the
chassis or the router will go into a critical failure mode and shutdown
due to an overtemp condition.

Troubleshooting an AC Power Subsystem
AC PEMs provide –48 VDC OUTPUT. The +5 VDC OUTPUT from the CSF
powers the MBus module on each card in the system. The MBus module, in turn,
control the DC-DC converters also present on each card in the system. The
DC-DC converter takes –48 VDC from the power supply and converts it into +2.5,
+3.3 and +5 VDC, which is distributed to the card circuitry.
AC PEMs are monitored by the MBus module and the RP for over- or
undervoltage and over- or undercurrent conditions.
Begin checking the power subsystem by first looking at the LEDs on the power
supply. The INPUT OK LED on an AC PEM lights when AC power is applied;
the OUTPUT OK LED lights when the PEM power switch is turned on.
Figure 4-1 shows the location of the LEDs on the AC PEM (item 5).

•Verify that each power supply in the router is attached to a separate AC power
source.
•If the router is connected to an uninterruptable power supply (UPS), verify
that the UPS is functioning correctly. Note that there might be a UPS for each
power supply in the system.
If the AC power source wiring appears to be okay, but the power supply
OUTPUT OK LED remains off, go to Step 3.
Step 3 Plug the power cord into a different, but compatible AC outlet.
•If the power supply OUTPUT OK LED is on, the original AC outlet is faulty
and cannot be used. Notify the appropriate facilities personnel and go to
Step 6.
•If the power supply OUTPUT OK LED remains off, go to Step 4.
Step 4 Exchange the existing power cord for another power cord.
•If the power supply OUTPUT OK LED is on, the original power cord is faulty
and must be replaced. The AC portion of the power supply is working
normally, go to Step 6.
•If the OUTPUT OK LED still fails light when connected to a different power
source with a new power cord, the power supply is probably faulty. Go to
Step 5.
Step 5 If a spare power supply is available, replace the existing module with the spare
and restart the system.
•If the OUTPUT OK LED on the spare power supply is on, the power supply
is working normally, go to Step 6. The original power supply is faulty and
should be returned for replacement.
Step 6 Is the power supply INPUT OK LED on?
•If yes, the power supply is functioning normally.
Note In a Cisco XR 12406 router with two power supplies, the output power
from the second power supply is adequate to maintain router operation.
•If no, and there is no other system activity (fan assembly is off; line cards are
not powered), the power supply is faulty. Replace the power supply.

Troubleshooting the Processor Subsystem
If you are unable to resolve the problem or if you determine that either the PEM
or power wiring is faulty, contact a service representative for assistance.
Troubleshooting the Processor Subsystem
The Cisco XR 12404 router processor subsystem consists of the RP, the line
cards, and the CSF card. The system cannot operate unless the RP is installed. The
RP and the line cards each have two processors. One processor is the main
processor; and the other processor is a component in the MBus module.
•The MBus module begins operation as soon as power is applied to the system.
The MBus module determines the type of card it is mounted on and whether
it should turn on the DC-DC converter.
•The RP MBus module turns on card power after a brief delay; the line card
MBus modules delay turning on power until they receive a command from the
RP.
A Cisco XR 12404 router requires that one RP be installed, or the system cannot
operate. A line card that is partially connected to the backplane can send
incomplete signals to the RP, which could cause the system to hang. If necessary,
you can troubleshoot individual line cards, but first make sure that the RP is
installed properly and the system software has initialized successfully.
Note The primary RP must be installed in Slot0 which is a narrow slot. If a redundant
RP is installed in another slot, a narrow card filler panel must be used to ensure
proper air flow through the chassis and electromagnetic compatibility (EMC).
A power-on self-test (POST) runs immediately at power-on to determine the
condition of the RP memory. Results are displayed in the alphanumeric LED
display as a pass/fail message.

Troubleshooting Using the RP Alphanumeric Display
You can use the alphanumeric display to isolate a problem with the RP. The two
rows on the alphanumeric display are powered separately:
•The upper row receives power from the DC-to-DC converters on the RP.
•The lower row is powered directly from the MBus on the RP through the
chassis backplane.
–
If the lower row is not operating, the MBus module may be
malfunctioning.
–
If the MBus module is operating, the lower row could be on even if the
RP failed to powered on.
•If neither the upper nor the lower row is on, but the power modules and the
blower modules are operational, the RP may not be installed properly, or the
+5 VDC output from the chassis backplane is faulty.
–
Make sure that the system is powered on.
–
Initialize the RP by ejecting it from the chassis backplane and then
reseating it.
Caution The soft reset (NMI) switch is not a mechanism for resetting the RP and reloading
the Cisco IOS image. It is intended for software development use. To prevent
system problems or loss of data, use the soft reset switch only when instructed by
a Cisco certified service representative.
•If both the upper and the lower displays are operating, check the meaning of
the messages (see Table 4-3).
When the DC-to-DC converters are powered-on by the MBus module, the RP
processor begins the boot process and displays various status messages. Some
messages appear briefly; while others appear for several seconds. If the
messages appear to stop at a particular point, the boot process may be halted.
–
Make a note of the message.
–
Turn off power to the router, then turn on the power again to reset the
router and start the boot process. If the router halts again, replace the RP.

Check the following to help isolate a problem with the RP.
•Are both alphanumeric LED displays on?
–
The two displays are powered separately. The left display receives power
from the DC-DC converter on the RP. The right display is powered
directly from the power supply; therefore, even if the RP has not powered
up, its right display could be on. If both displays are off, the RP may not
be properly seated in the backplane connector, there might be a problem
with the MBus module on the RP, or the system power supply might be
off.
•If both displays are on, check the message being displayed. As soon as the
DC-DC converter is turned on by the MBus module, the processor on the RP
begins the boot process. Status messages are displayed as the boot process
continues. If one of the messages appears frozen, the boot process could be
halted. Write the message being displayed on a piece of paper. Turn off the
PEM power switches, then turn them back on to reset the system and start the
boot process again. If the system halts again, the RP could be faulty and may
need to be replaced.
–
If the PEMs and fans appear operational but none of the RP LEDs or
displays are on, suspect that the RP has not been properly installed or that
the +5 VDC output from the CSF card is faulty.
–
Turn the PEM power switch to the OFF position on each PEM.
–
Loosen the two captive screws on the left and right sides of the
RP faceplate, and use the ejector levers to eject and reseat the RP. Tighten
the captive screws, then power on the system by turning the PEM power
switches on.
•Is a Critical, Major, or Minor alarm LED on the CSF card on?
–
If any of the three CSF card LEDs is on, a fault has been detected in the
system. Check the console for messages indicating the source of the
problem.
–
There could be a false error indication originating from the RP. You may
want to reseat or replace the RP.
Caution The RP reset switch resets the RP and the entire system. To prevent system errors
and problems, use it only at the direction of a Cisco-certified service
representative.

Troubleshooting the Line Cards
As each line card powers on, a power-on self-test (POST) is performed on the line
card memory. A full set of field diagnostics can also be run on a line card from
the system console providing a pass/fail message both in the line card
alphanumeric LED display and on the system console.
Check the following to help isolate a problem with the line cards:
•Are both banks of alphanumeric LED displays on?
–
The two displays are powered separately. The left display receives power
from the DC-DC converter on the line card. The right display is powered
directly from the power supply. So, even if the line card has not powered
up, the right display could be on. If both displays are off, the line card
might not be fully plugged into the backplane connector, there might be
a problem with the MBus module on the line card, or the system power
supply may be off.
–
If both displays are on, check the message being displayed. As soon as
the DC-DC converter is turned on by the MBus module, the processor on
the line card begins the boot process. Status messages are displayed in the
alphanumeric displays as the boot process continues on the line card.
The system attempts to boot identical line cards in parallel. Further, the system
boots line cards as soon as they are powered on and become available for backup.
During the line card boot process, which occurs immediately after the RP boot
process, you can observe the alphanumeric LED displays on each line card. For
additional information about the displays and definitions, see the Cisco IOS XR
Troubleshooting Guide (see “Obtaining Documentation, Obtaining Support, and
Security Guidelines” section on page -xii).

•7 fans
•2 controller cards
•1 connector
Check the following to help isolate a problem with the cooling system:
•Do the fans come on?
Note In noisy environments listen for the fans. Place your hand at the left side
of the chassis beside the fan tray assembly to feel for air being forced out
the exhaust vents.
•If the fans come on, the –48 VDC line from the power supply to the fan tray
assembly is good.
•If the fans do not come on, there could a problem with either the fan tray
assembly or the –48 VDC power. Check the OUTPUT FAIL LED on each
power supply. If the OUTPUT FAIL LED on a PEM is on, the PEM is faulty
and should be replaced.
•If the fans do not come on and the PEM OUTPUT FAIL LED is off (–48 VDC
is OK), ensure that the fan tray assembly is seated properly to the backplane
connector.
–
Remove the fan tray assembly by loosening the two captive screws
securing it to the chassis. Pull the assembly out a few inches and firmly
push in back in to reseat it. Tighten the two captive screws.
•If the fans do not come on, there could be a problem with the fan tray
assembly controller card.

clearance (at least 6 inches, 15.24 cm) around all sides of the chassis to allow
cooling air to enter and hot air to exhaust. Should an overtemperature
condition occur at initial startup:
–
Check the condition of the air filter. If the air filter appears dirty, you
should remove the air filter and replace it; or remove the air filter, take it
away from the chassis, and vacuum the air filter.
–
The overtemperature condition message could also indicate a faulty
component or temperature sensor. Before the system shuts down, use the
show environment all or show environment table commands to view
the internal system environment including voltages and temperatures
measured at each card.
If you are still unable to resolve the problem, contact a service representative for
assistance.

Maintaining the Router
This chapter contains safety at the field replaceable unit (FRU) level, removal and
replacement instructions for FRUs and procedures to troubleshoot the FRUs.
Your Cisco XR 12404 router is equipped as ordered and is ready for installation
and startup when it leaves the factory. After you install and configure the router,
you may need to perform other procedures to ensure that the router continues to
operate properly. Also, as your networking requirements change, you may need to
upgrade your system by adding or changing components.
Before performing the procedures in this chapter, be sure to review the safety
information in the “Laser Safety” section on page 2-6, and the “Lifting
Guidelines” section on page 2-6.
You should also be familiar with the Regulatory Compliance and Safety
Information for the Cisco 12000 Series Router document (78-4347-xx) that came
with the router.
Caution All procedures in this chapter assume that you are wearing and ESD-preventative
wrist strap. Refer to “Preventing Electrostatic Discharge Damage” section on
page 2-4 for additional information.

Chapter 5 Maintaining the Router
Powering Off the Router
Powering Off the Router
Unless otherwise noted, the maintenance tasks described in this chapter can be
performed while the router remains powered on. Most Cisco XR 12404 router
field replaceable units (FRUs) support online insertion and removal (OIR), which
means they can be removed and installed (hot-swapped) while the router remains
powered on.
•Line cards and the fan tray assembly are hot-swappable.
•PEMs and RPs also support OIR, but are hot-swappable only when the system
is equipped with two PEMs or two RPs, respectively.
•The power distribution unit (PDU) and CSF card do not support OIR.
Use the following procedure to power off an AC- or a DC-powered router.
Step 1 Turn off the power switches (AC) or circuit breaker switches (DC) on the PEMs.
Step 2 Turn off the facility circuit breakers for power source lines connected to the PDU.
Step 3 When the procedure requires that the router be disconnected from source power:
•AC-powered systems—Unplug the AC power cords from the power outlets.
•DC-powered systems—Disconnect and remove the source DC wires from the
power connector blocks on the PDU.
Step 4 Verify the following conditions:
•LEDs on the PEMs are off.
•LEDs on the RP, all line cards, and CSF are off.
•The fans in the fan module tray are off.

Removing and Replacing a DC PDU
Step 3 Loosen the terminal block screws to disconnect the positive, negative, and ground
wires from the DC PDU terminal block of the faulty PEM (Figure 5-13).
Warning
To prevent injury and damage to the equipment, always remove the source DC
power leads and ground from the power shelf terminals in the following order:
(a) negative (–), (b) positive (+), (c) ground.
Caution Before removing wires, be sure to note the color for each type of wire (positive,
negative, and ground). Because there is no color code standard for source DC
wiring, you must be sure which power wires are connected to the proper positive
(+) and negative (–) terminal ports. Typically, green (or green and yellow) indicate
a ground wire, while power wire leads may be labeled positive (+) or negative (–).
Because this is not always the case, the safest way to indicate the polarity of a wire
is to note its color and identify it as described in this procedure.

Chapter 5 Maintaining the Router
Removing and Replacing an RP or Line Card
Removing and Replacing an RP or Line Card
Line cards can occupy any slot, zero (0) through 3 in the RP and line card cage.
The Cisco XR 12404 router is configured with the RP in slot 0 (Figure 5-17).
Redundant RPs can be placed in any slot, but requires a line card spacer to comply
with EMI emission standards.
Note Installing a card in slot 1 when all other slots are filled may require additional
effort to properly seat the card. Because of the tight fit you have to either apply
extra pressure to properly seat the card, or you can remove the card in slot 2 before
installing the card in slot 1. After you install the card in slot 1 you can reinstall
the card in slot 2.
Cisco XR 12404 router line cards support OIR, so they can be removed and
installed while the router remains powered on. RPs also support OIR, but are
hot-swappable only when the system is equipped with two RPs.
Additional line card information can be found in the respective installation and
configuration documentation for each type of line card.

Step 1 Identify the RP or line card to be replaced and write down the following
information:
•The RP cable connections on the RP.
•The number and type of RP or line card, so that you will know the location of
the card when you re-install it or the replacement, in the card cage.
•The network interface cable connection ports, on the RP or line card.
Step 2 On RPs and line cards with multiple ports, start with the left port on the card and
disconnect the interface cable connectors from each of the ports.
Step 3 After all of the interface cables are disconnected, loosen the two captive screws
on the cable-management bracket and pull the bracket away from the card.
Step 4 Loosen the two ejector lever captive screws at each end of the card faceplate.
Step 5 Simultaneously pivot the ejector levers away from each other to unseat the card
from the backplane connector (Figure 5-18).

Step 6 Grasp the edges of the card carrier with both hand to support it and remove the
card.
Caution Remove each RP or line card completely from the slots. A card left
partially inserted into the slot can damage the EMI shielding on card in
the slot directly below.
•Immediately place the RP or line card in an antistatic bag to protect it against
ESD and to prevent dust from getting to the fiber-optic connectors on
fiber-optic line cards.
•If you plan to return the defective unit to the factory, repackage it in the
shipping container you received with the replacement RP or line card.
Step 7 Remove the RP or line card from its shipping package and antistatic bag.
Caution Handle the RPs and line cards by the metal card carrier edges only;
avoid touching the board itself or any connector pins.
Step 8 Seat the RP or line card:
a. Set both edges of the RP or line card into the card slot and partially slide the
card into the chassis.
b. Pivot the ejector levers away from each other by rotating each ejector lever
outward away from the faceplate.
c. Continue sliding the card into the slot until the ejector levers make contact
with the front of the card cage, then stop.
d. Seat the card by grasping each ejector levers and simultaneously pivot them
toward the card faceplate.
Note The line card does not boot properly if not fully seated.

Step 9 Tighten the captive screws on the card.
Note The card captive screws must be tightened to meet EMI specification
standards.
Repeat Step 1 through Step 9 for any additional replacement RPs or line cards,
and then proceed to the next section.
Attaching the Cable-Management Bracket and Connecting
Cables
The Cisco XR 12404 router line cards use cable-management brackets to:
•Organizing the network interface cables
•Keeping the network interface cables out of the way
•Positioning connectors at their respective ports on the line card faceplate
•Keeping the cables free of sharp bends (excessive bending in a network
interface cable can cause performance degradation)
When you install a new RP or line card, you need to attach the line card
cable-management bracket to the faceplate of the card before connecting the
cables. The type of cable-management bracket used by a line card is determined
by the card type and the number of network interface ports it has.
Use the following procedure to attach the cable-management bracket and cables
to a line card.
Step 1 Orient the top of the cable-management bracket with the top of the line card
faceplate (the end opposite the two four-character alphanumeric displays.)
Step 2 Align the two captive screws on the bracket with the threaded insert holes near the
ejector levers on each end of the line card faceplate and finger-tighten the screws.

Step 3 Use a flat-blade screwdriver to secure the two captive screws.
Caution Do not overtighten the captive screws; overtightening the screws can strip the
threads on the screw or the insert in the faceplate.
Step 4 Repeat steps 1 through 3 for any remaining line cards.
Step 5 Attach an appropriate number of velcro straps through the slots in the
cable-management bracket to support the network interface cables (Figure 5-19).
a. Pull the small end of the velcro strap through the slot in the
cable-management bracket.
b. Insert the small end of the velcro strap into the slot in the wide end of the
velcro strap.
c. Pull the small end through the velcro strap slot to secure it to the cable-
management bracket.

Step 6 Proceeding from the left port on the line card to the right port (on line cards with
multiple ports), identify the network interface cable for the line card port and
insert the cable connector into the line card port (see Figure 5-19).
a. Align the interface cable with the cable-management bracket.
b. Repeat for the remainder of the interface cables for this line card.
Note Carefully adjust the interface cables in the cable-management bracket to
prevent any kinks or sharp bends in the interface cables. Kinks and sharp
bends can destroy or degrade the ability of the optical fiber to propagate
the signal-encoded beam of light accurately from one end of the cable to
the other. Also, allow adequate strain relief in the interface cables.
Step 7 Secure the interface cables to the cable-management bracket by wrapping the
velcro straps around them (see Figure 5-19).
Note Do not wrap the velcro straps too tightly.
