Chassis
The ASR 5500 is a 21RU, 19" rack-mount midplane-based chassis with input/output (I/O) and processing cards in the
rear, and fabric cards in the front. Two ASR 5500 chassis fit into 42RU of rack space. However, the typical deployment
will be a single chassis per rack with other equipment in the same rack.
The rear cards are larger and used for chassis management, I/O and session processing. The smaller front cards are used
for fabric crossbars and persistent storage. There are 10 slots at the front and rear of the chassis.
The rear slots have a common midplane connector that is shared between the supported cards. This allows for different
mixes of I/O and processing capacity depending on the customer's intended use.
The chassis can be flush-mounted or mid-mounted in a rack or equipment cabinet.
Figure 2. Front and Rear Views of the ASR 5500 Chassis
Power
The chassis accepts up to eight 80-amp, -48 VDC power feeds across redundant power filter units (PFUs). The
connections are made at the top-rear of the chassis. The front-mounted PFUs incorporate separate circuit breakers for
each power feed.

Cooling
The ASR 5500 uses two types of fan tray units and a total of four fan trays per chassis – two front fan trays and two rear
fan trays. Air is drawn from the front and sides of the chassis and exhausted out the top rear and sides. Two fan trays are
mounted at the bottom of the chassis with another two at the top. The bottom fan trays incorporate replaceable
particulate air filters.
Slot Numbering
The rear slots are numbered 1 through 10 with slots 5 and 6 used for the chassis management cards. The front slots are
numbered 11 through 20. Lower slot numbers begin at the left side. There are no direct relationships between front and
rear cards.
The figure below shows the slot numbering sequence and the general layout of other components in the ASR 5500
chassis.

Power Filter Units (PFUs)
Two PFUs mount at the top front of the chassis. Each PFU supports four power planes.
A total of eight -48 VDC, 80-amp power feeds are required for a full chassis. The eight feeds operate in a 4+4 redundant
configuration. In lab environments where power redundancy is not required, four 80 A lines can be used.
Cable Management System
The ASR 5500 cable management system consists of two components. The first is a tray that mounts at the rea r of the
chassis immediately below the card cage. The second is a cable management bracket that mounts to the front panel of
each Management Input/Output (MIO) or Management Input/Output Universal (UMIO) card.
Network cables are fed from either side or both sides of the tray and are then routed to the MIO/UMIO ports. The cables
are secured to the cable management brackets on the MIO/UMIOs via cable ties or hook-and-loop straps, and within the
cable management tray via hook-and-loop straps.

Midplane
The midplane within the ASR 5500 chassis interconnects rear input/output ports and processing cards with front fabric
cards. The larger rear cards support chassis management, input/output, and session processing. The smaller front cards
provide fabric crossbars, persistent storage and system status monitoring.
The rear slots have a common midplane connector that is shared between the supported cards. This allows for different
mixes of input/output and processing capacity depending on the customer's intended use. The two MIO or UMIO slots
(5 and 6) have additional midplane connections to perform chassis control operations, including support for a serial
Console port and dual remote management ports.

Card Types
The ASR 5500 supports rear cards and front cards. Rear cards are larger and perform node management, packet
processing and I/O functions (traffic sources). Front cards determine the amount of bandwidth for the switching fabric
(crossbars), and indicate the operating and alarm status of the ASR 5500. The figure below is a simplified block diagram
showing the ASR 5500 card architecture.

Rear Cards
The ASR 5500 supports four types of rear-mounted cards:
Management I/O Card (MIO) or Management I/O Universal Card (UMIO) [two per system]
Data Processing Card (DPC) or Data Processing Universal Card (UDPC) [up to eight per system]
The ARS 5500 supports ten rear cards, a mix of MIOs, UMIOs, DPCs and/or UDPCs. Each card is interconnected with
the others via the switching fabric.
Important: UMIO cards and UDPCs are direct replacements for MIO cards and DPCs. However, a special
Universal PID license must be purchased and installed on the chassis for each installed UMIO and UDPC. Contact your
Cisco account representative for additional information.
Management I/O
The ASR 5500 chassis supports two MIO and/or UMIO cards placed in the rear facing slots of the chassis. These cards
perform chassis management, as well as local context and non-local context external I/O operations.
Important: The MIO/UMIO cards automatically implement 1:1 port redundancy (active/standby). Ports are 1:1
redundant across slots 5 and 6. For example, port 10 on the MIO in slot 5 is redundant with port 10 on the MIO in slot 6.
Each MIO/UMIO has:
One CPU subsystem with 96 GB of RAM
Four NPU subsystems
The two 1000Base-T (1GbE) ports on MIO/UMIO cards can only be used for local context (OAM). An MIO/UMIO
includes support for:
Midplane connections for chassis control operations
SAS storage controller for FSC solid state drives (SSDs)
RS-232 serial console (RJ45) for CLI management
USB port for an external flash device
32 GB SDHC internal flash device
MIO/UMIO cards support two daughter card (DCs) for external I/O interfaces (100 Gbps aggregate per DC). The
optical ports on the daughter cards can only be used for non-local context. The currently available DC supports ten 10
GbE interfaces. The interface ports accept SFP+ SR and LR transceivers.
Important: MIO/UMIO daughter cards are not user installable or replaceable.
Important: MIO/UMIO cards are shipped with SFP+ SR or LR transceivers installed.

Data Processing Card
The ASR 5500 chassis supports multiple DPCs and/or UDPCs in the rear facing slots of the chassis.
The DPC/UDPC has two identical CPU subsystems with each containing:
96 GB of RAM
NPU for session data flow offload
Crypto offload engines located on a daughter card
DPC/UDPCs manage subscriber sessions and control traffic.
Front Cards
The ASR 5500 supports two types of front-mounted cards:
Fabric and Storage Card (FSC)
System Status Card (SSC)
The crossbars that comprise the switching fabric are on the FSCs. The ASR 5500 supports multiple FSCs. Each FSC
provides six physical fabric planes. When fully populated, there are 24 fabric planes in the system. A physical fabric
plane provides full-mesh connectivity between all traffic sources.
Fabric and Storage Card (FSC)
The ASR 5500 chassis supports multiple FSCs in front facing slots of the chassis.
The FSC features:
Fabric cross-bars providing in aggregate:
120 Gbps full-duplex fabric connection to each MIO/UMIO
60 Gbps full-duplex fabric connection to each DPC/UDPC
Two 2.5" serial attached SCSI (SAS), 200GB solid state drives (SSDs) with a 6 Gbps SAS connection to each
MIO/UMIO.
Every FSC adds to the available fabric bandwidth to each card. Each FSC connects to all MIO/UMIOs or DPC/UDPCs,
with a varying number of links depending on the MIO/UMIO or DPC/UDPC slot. Three FSCs provide sufficient
bandwidth while the fourth FSC supports redundancy.
Important: Although four FSCs are required for redundancy, the system can operate with three FSCs in the
presence of a fourth failed FSC. Four FSCs must be installed for normal operation.
Important: The SSDs are not field replaceable units (FRUs). If an SSD fails the FSC must be replaced.
The ASR 5500 uses an array of solid state drives (SSDs) for short-term persistent storage. The RAID 05 configuration
has each pair of drives on an FSC striped into a RAID 0 array; all the arrays are then grouped into a RAID 5 array. Each
FSC provides the storage for one quarter of the RAID 5 array. Data is striped across all four FSCs with each FSC
providing parity data for the other three FSCs. The array is managed by the master MIO/UMIO.

Important: A minimum of three FSCs must be online at all times for the array to operate. When an FSC is
removed, one RAID 0 array is lost with the RAID 5 array providing redundancy.
Important: Removal of an FSC while the array is degraded or rebuilding may result in data loss.
The array appears under /hd-raid and is available to all DPC/UDPCs and MIO/UMIOs.

Installing Cards
The installation procedure is identical for all cards in the chassis.
Caution: During installation, maintenance, and/or removal, wear a grounding wrist strap connected to the
ASR 5500 chassis to avoid ESD damage to the components. Failure to do so could result in damage to sensitive
electronic components and potentially void your warranty.
Important: Save several of the shipping cartons and ESD protective bags for use if a card must be returned to
Cisco for fault analysis.
Important: On a chassis equipped with the cable management tray, you must lower the tray to insert rear circuit
cards. Refer to the Lowering the Cable Management Tray section in the Cable Management System Installation
appendix. The cable management tray can be installed after all rear cards have been installed.
Important: Install cable management brackets on MIO cards before inserting the card into the chassis. Refer to
the Installing the Cable Management Bracket on an MIO or UMIO Card section in the Cable Management System
Installation appendix.
Card Interlock Switch
The top and bottom handles of ASR 5500 circuit cards incorporate hooks that fit behind the upper and lower rails of the
card cage. Lifting the handles outwards ejects the card from the midplane. Pushing the handles inwards seats the card
into the midplane.
The top handle incorporates an interlock switch that signals the system that a card is seated in the slot. The blue
subhandle must be pushed fully upward to engage the interlock switch. The subhandle also locks the top handle against
the front of the card. Tightening the captive screw within the top handle secures the subhandle and circuit card to the
card cage.

MIOs or UMIOs support two autosensing RJ45 10/100/1000Base-T (IEEE 802.3ab) Ethernet, twisted-pair copper
interfaces (logical Ports 1 and 2) for out-of-band system management access to the CLI.
Important: To comply with GR-1089 intra-building, lightning-immunity requirements and FCC Radiated
Emissions Criteria, you must use shielded-twisted pair (STP) cable and ensure that it is properly terminated at both
ends.
Caution: The 1000Base-T management ports are suitable for connection to intra-building or unexposed wiring
or cabling only. These intra-building ports MUST NOT be metallically connected to interfaces that connect to the
outside plant (OSP) or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type
4 ports as described in GR-1089-CORE, Issue 5) and require isolation from the exposed OSP cabling. The addition of
Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.
The ports support MDI and MDI-X connectors. Ethernet ports normally use MDI connectors and Ethernet ports on a
hub normally use MDI-X connectors.
An Ethernet straight-through cable is used to connect an MDI to an MDI-X port. A cross-over cable is used to connect
an MDI to an MDI port, or an MDI-X to an MDI-X port.

or its wiring. This interface is designed for use as an intra-building interface only (Type 2 or Type 4 ports as described
in GR-1089-CORE, Issue 5) and requires isolation from the exposed OSP cabling. The addition of Primary Protectors is
not sufficient protection in order to connect these interfaces metallically to OSP wiring.

CO Alarm Interface
The Central Office (CO) Alarm interface on the SSC is a DB15 female connector that supports three low voltage,
normally-closed/normally-open dry-contact relays (see Figure 7-1). These Form C relays interface with an CO alarm
monitor panel to trigger external audio and/or visual indicators.
Three alarm levels are supported by the relays:
Minor Alarm – This alarm is triggered when a high temperature is detected on a card, causing the fan tray to
switch the fans to high speed.
Major Alarm – This alarm is triggered when there is a:
Hardware failure that causes the card to be placed in an off-line state
PFU failure or removal from the chassis
Failure of one or more fans on any of the upper or lower fan tray units
Fan tray failure or any fan tray unit is removed from the chassis
Critical Alarm – This alarm is triggered when a degradation in service is detected. For example, if the system is
supporting a large number of subscribers and DPCs are removed, the amount of available CPU and memory
resources available for use are reduced.

Power Cabling
This chapter describes how to connect -48 VDC power feeds to the Power Filter Units (PFUs) on the ASR 5500 chassis.
It includes the following sections:
Power Considerations
Internal Power Planes
Power Cable Requirements
Connect Power Feeds to the PFUs
Important: The -48 VDC Battery Return (BR) input terminals to the PFUs are not connected to the equipment
frame (chassis) are treated as Isolated DC returns (DC-I) in compliance with GR-1089-CORE (sec.9.8.3).
Page 86
Power Cabling
▀ Power Considerations
▄ ASR 5500 Installation Guide
86
Power Considerations
Each chassis supports up to eight -48 VDC, 80-amp power feeds, four per PFU. Table 8-1 lists the power load factors
that should be considered for this installation site. Each feed consists of a supply and return cable.
Important: The power source must be a UL/CSA listed device with a regulated output no greater that -60VDC.
Typically, the DC power feeds are fed from a power distribution frame (PDF) to a power distribution panel (PDP) at the
rack.
Important: The DC power Battery Return (BR) or positive terminal, must be grounded at the source end (power
feed or mains power end).
Important: Minimum 4 AWG multiple strand, high-flex cable is recommended for final connections from the
PDP to the PFUs.
Each feed connects to supply and return terminals on the rear of the PFUs using two-hole lugs crimped to the end of
each cable. The feed cables are routed through openings in each side of the chassis. The input terminals are wired
through EMI filters to the ASR 5500 backplane.
The circuit breakers at the power distribution panel must disconnect the supply line of each -48VDC feed. However, it is
recommended that the circuit breakers at the power distribution panel simultaneously disconnect both poles (supply and
return) for each -48 VDC feed to completely isolate the ASR 5500 from the power source.
To maintain power redundancy, separate –48 VDC supply circuits should be used to feed each DC power input on both
PFUs.
Caution: Set the circuit breakers on the distribution panel to the OFF position before making the power
connections at the PFUs.
Each power input cable must be terminated with a supplied Panduit LCD4-14AF-L 2-hole, 90-degree lug using the
appropriate crimping tool and die.
The following alternate lug types (not supplied with the chassis) are also approved for use on the power feeds:
Panduit LCC4-14AF-L, 4 AWG, 2-hole, 90-degree long barrel lug
Burndy YAZ2C2TC1490, 2 AWG, 2-hole, 90-degree long barrel lug
If a DC power input should fail, the operating supply circuits continue to power the ASR 5500.

Power Feed Connections
The figure below shows a recommended method for connecting -48 VDC power feeds from the power distribution
frame (PDF) through a power distribution panel (PDP) to the power filter units (PFUs) on the ASR 5500 chassis.
This method preserves electrical redundancy from the PDF to the PFUs.

▀ Power Cable Requirements
▄ ASR 5500 Installation Guide

Power Cable Requirements
Sizing Power Cables
The following guidelines should be adhered to when sizing cable gauges for connecting the PFUs to a rack-mounted
power distribution panel.
Each conductor between the PDF and PDP should be calculated assuming a 0.3 volt drop from the PDF to the
panel.
Each cable between the PDP and ASR 5500 PFUs should be calculated a 0.3 volt drop from the panel to the
chassis. This is a total voltage drop of 0.6 volts.
Use high-flex, multiple-strand cable (minimum 4 AWG) between the power distribution panel and the chassis.
Terminating Power Cables
Each cable should be terminated with a 90 degree, 2-hole lug (supplied). Each feed consists of a supply (-48VDC) and
return (RTN) cable. The feed cables terminate at the rear of each PFU on 0.25-inch posts spaced 0.63-inch on center.
Cable Routing
All feed cables must be routed through the openings at the upper rear sides of the chassis.
Method of Connection
The method of connection at each PFU terminal is: flat washer, lug, lock washer and nut (7/16-inch). The nut(s) must be
torqued to 50 in-lb. (5.65 N-m).
Insulate Lugs
Use heat shrink tubing or non-conductive tape to insulate much of the exposed metal on the lug without interfering with
the attachment point.
Crimp Lugs on Cables
Use the Panduit® lugs supplied with the chassis (LCD4-14AF-L). The lug must be crimped to the end of a ground cable
using Panduit crimp tool part number CT-720-1 (die color: gray, P29). The wire strip length is 7/8-inch (22 mm),
Follow the OEM recommendations for preparing and crimping the lugs on the ends of each feed cable.
Label All Cable
Label the supply and return cables going to each terminal on the rear of the PFUs. Include the terminal number (A-1 to
A4, B1 to B4) and power distribution panel circuit number. This will facilitate troubleshooting, as well as removal and
replacement of a failed PFU.

Caution: To avoid personal injury or possible equipment damage, ensure that the circuit breakers for all
ASR 5500 chassis feeds from the power distribution panel are all set to OFF before attempting to attach power cables to
the PFU(s).
Caution: Verify that all circuit breakers on the front panels of both PFUs (four per PFU) are set to OFF before
attaching power feed cables to the PFUs (see figure below). The breakers must remain OFF until the chassis is to be
powered up.
Figure 18. PFU Front Panel
Important: The eight power terminals on the back of each PFU are shipped with nuts and washers attached.
Step 1 Remove the plastic power input cover from the top-rear of the ASR 5500 chassis. Use a Phillips #2 head screw driver to
loosen the two captive screws securing the cover to the chassis. Removing this cover exposes the power feed terminals
at the rear of the PFUs.

▀ Connect Power Feeds to the PFUs
▄ ASR 5500 Installation Guide
92
Step 2 Remove one nut, a lock washer and a flat washer from each of the eight terminals; leave the bottom nut on each
terminal. The nuts on the PFU terminals require a 7/16-inch nut driver or socket wrench for removal.
Step 3 Before proceeding, verify that the bottom nuts on all terminals are torqued to 50 in-lb. (5.65 N-m).
Step 4 Slide a 1.25 in. (3.2 cm) length of heat shrink tubing over the end of each feed cable. You can skip this step if you
choose to use non-conductive tape to insulate the crimp portion of the 2-hole lug.
Step 5 Crimp a 2-hole 90o lug to each -48 VDC and Return cable.
Step 6 Slide the heat shrink tubing over the crimp portion of the lug until it contacts the flat attachment point. Use a heat source
to warm the tubing until it tightly wraps the metal. Alternatively, you can firmly wrap the crimp portion of the lug with
a non-conductive tape.
Step 7 Thread each cable through an opening in the side of the chassis and route it to the appropriate terminal (-48V 1, Return
1, -48V 2, Return 2, etc.). Rectangular openings are provided at the sides of the chassis for this purpose. See the figure
below.
Caution: Do not route any cables through openings in the plastic power input cover. The openings are for air
flow only.
Step 8 Install each lug over the two terminals.
Step 9 Secure each lug to the terminals with flat washers, lock washers and nuts. Tighten the nuts while holding the lug
perpendicular to the attachment studs and maintaining as much separation as possible with adjacent cables. The nuts
should be torqued to 50 in-lb. (5.65 N-m).
Important: The supply and return lugs for each power feed will be separated by the ridge in the insulating
spacer shown in Detail A of the figure below.
After all feeds are attached, move/push all cables to verify there are no potential shorts.
Caution: To avoid the risk of fire, take proper precautions to ensure that the power supply and return lugs are
not touching.
Step 10 Continue installing the feeds on the terminals until all power feed connections have been completed to both PFUs.
Step 11 Reinstall the plastic terminal cover on the top-rear of the chassis.
Caution: To avoid the risk of personal injury and/or potential damage to the system, never operate the chassis
without the power input cover.
Step 12 Proceed to the System Power-up chapter for information and instructions on applying power to the chassis and verifying
that the installation was successful.

Chapter 9
System Power-up
This chapter describes the boot process that occurs when the system is first powered up.
It includes the following sections:
System Boot Process
Applying Power to the Chassis
Verifying System Startup
Important: The system boot process is governed by StarOS licenses. Refer to Chassis, UMIO and UDPC
License Requirements for additional information on the effect licenses and card types have on the boot process.
Page 96
System Power-up
▀ System Boot Process
▄ ASR 5500 Installation Guide
96
System Boot Process
The boot process is initiated after power is applied to the chassis.
Step 1 When power is first applied to the chassis, the MIOs or UMIOs in slots 5 and 6 and all fan trays are the first to receive
power.
Once the software is running, power is then quickly applied to the remaining cards in the system.
Important: The fans in the fan trays initially rotate at medium speed until the first MIO completes its boot up. If
no MIO or UMIO boots successfully within a few minutes, the fan speed increases to 100%.
Step 2 During the startup process, each card performs a series of Power-On Self Tests (POSTs) to ensure that the hardware is
operational. These tests also verify that the card meets all license requirements to operate on this chassis.
Step 3 If the MIO or UMIO in slot 5 successfully executes all POSTs, it becomes the active chassis management MIO or
UMIO for the system. The MIO or UMIO in slot 6 becomes the standby.
Important: If the MIO or UMIO in slot 5 fails to boot, the MIO or UMIO in slot 6 automatically becomes the
active chassis management MIO.
Step 4 The active MIO/UMIO begins loading the operating system software image that is designated in the boot stack. The
boot stack entries are contained in the boot.sys file that resides on the MIO/UMIO's flash device.
The standby MIO/UMIO observes the active card's startup. If the file on the active card is loading normally, the standby
MIO/UMIO boots from the active card's image. If the active MIO/UMIO experiences a problem during this phase, the
standby card loads its software image, that is designated by its own boot stack entry in its boot.sys file, and takes control
of the system as the active card.
Step 5 After the software image is loaded into MIO RAM, the active card determines if other cards are installed in the chassis
by applying power to the other slots and signaling them. If the chassis slot contains a card, power is left on to that slot.
All empty slots are powered off.
Important: If no MIOs or UMIOs are installed in slots 5 and 6 or if they both fail to boot, other cards in the
system will not boot.
Step 6 When power is applied to the other installed cards, they each perform their own series of POSTs.
Important: After successful completion of the POSTs, each of the DPCs or UDPCs enter standby mode.
Installed DPCs or UDPCs remain in standby mode until they are made active via configuration.
Step 7 After entering the standby mode, each of the DPC/UDPC control processors communicate with the active chassis
management MIO to receive the appropriate code.
Step 8 Upon successful loading of the software image, the system loads a configuration file designated in the boot stack
(boot.sys file). If this is the first time the system is powered on and there is no configuration file, the active MIO
invokes the system's Quick Setup Wizard. Use the Quick Setup Wizard to configure basic system parameters that enable
the system to communicate across the management network.
Page 97
System Power-up
Applying Power to the Chassis ▀
ASR 5500 Installation Guide ▄
97
The Wizard creates a configuration file, saved as system.cfg, that can be used as a starting point for subsequent
configurations. The system is configured by automatically applying the configuration file during any subsequent boot.
After the system successfully boots and the initial configuration is applied, the system is ready to be configured or offer
services.
Applying Power to the Chassis
With all power and ground cables connected, you apply power to the chassis by following the instructions below.
Caution: Never operate the chassis if any slots are uncovered. This reduces airflow through the chassis and
could cause it to overheat. A card or blank panel must be installed in every chassis slot at all times.
Step 1 If the top-front cover is installed on the chassis, remove the cover to access the PFU circuit breakers.
Step 2 At the front of the chassis verify that the circuit breakers on the PFUs are in the OFF position.
Step 3 Set the circuit breakers on the power distribution panel (PDP) to ON.
Step 4 At the rear of the chassis, remove the plastic terminal cover to access the PFU input terminals.
Step 5 Use a voltmeter to check the voltage level and polarity across the input terminals for each PFU. The meter should
display a voltage approximately equal to that of the power source.
Step 6 Turn ON all the circuit breakers on both PFUs.
Step 7 Proceed to Verifying System Startup .
Step 8 When the initial checks are completed, reinstall the covers removed in step 1 and step 4.
