Note The line card slots are dedicated to only line cards; RSP/RP/FC cards cannot occupy these slots. The RSP/RP/FC slots are dedicated to only RSP/RP/FC cards; line cards cannot occupy these slots. A keying mechanism keeps line cards from entering RSP/RP/FC slots and RSP/RP/FC cards from entering line card slots; the keying mechanism pins engage before the card alignment pins engage.


Fiber and Interface Cable Management

Figure 1-13 shows how card interface cables are managed at the front of the Cisco ASR 9010 Router chassis using a cable management tray.

Figure 1-13 Cable Management Tray

 

The cable management tray is located above the card cage (the Cisco ASR 9922 Router and
Cisco ASR 9912 Router have an additional cable management tray below the bottom card cage) and does not interfere with the insertion or removal of cards. A hinged cover at the top of the tray can be raised for ease of access for routing cables.

Line cards and RSP/RP cards share the same cable management tray. Cables to a card must be disconnected before its removal (this does not affect adjacent cards). Removal of a line card or RSP/RP card does not require removal or adjustment of cables other than those associated with the card itself.

A cable management bend radius of 1.5 inches (3.81 cm) is accommodated. Line card slots at the extreme ends of the cable management trays use space outside of the chassis width to accommodate the 1.5-inch (3.81-cm) radii due to limited space per slot.

Space for the fiber bend radii and strain relief is 3.75 inches (9.53 cm) in front of the faceplate.

Figure 1-14 shows how the fiber and cables are routed upward away from slot number labels. Therefore slot number labels, located at the lower part of the card cage, are not obscured by the cables.

Figure 1-14 Fiber/Cable Routing in the Cisco ASR 9010 Router

 

Routing of DC Power Tray Source Cables

Power cables are located in the rear. The A and B source feeds to the DC power supply modules are separated so the cables route to opposite sides of the chassis. A cable tie down point is provided.

Figure 1-15 shows the DC power cable routing on the power trays.

Figure 1-15 Routing of DC Power Tray Source Cables

 

Slot Numbering and Marking

All card slots are clearly numbered. Labels identifying slots are visible from the front of the chassis and are clearly numbered below each slot. As mentioned previously, fiber and cables are routed upward and do not obscure the slot ID labels.

Figure 1-16 shows slot ID numbering for the Cisco ASR 9010 Router with version 1 power trays.

Route Switch Processor and Route Processor Cards

The RSP card is the main control and switch fabric element in the Cisco ASR 9010 Router, and Cisco ASR 9006 Router, and Cisco ASR 9904 Router. To provide redundancy, there can be two RSP cards in each router, one as the active control RSP and the other as the standby RSP. The standby RSP takes over all control functions should the active RSP fail.

The RP card is the main control element in the Cisco ASR 9922 Router and Cisco ASR 9912 Router. The RP card provides centralized chassis control, management, and data-plane switching. To provide redundancy, there are two RP cards in each router, one as the active control RP and the other as the standby RP. The standby RP takes over all control functions should the active RP fail.

On the Cisco ASR 9922 Router and Cisco ASR 9912 Router, the switch fabric has been moved to FC cards.

RSP Front Panel and Access Ports

System alarms reside on the RSP. Alarms consist of visual indicators with three levels: Critical (red), Major (red), and Minor (yellow). There is a console interface for remote viewing of alarms and fault information. The RSP has the following information and alarm LEDs and connectors:

  • One external Compact Flash type I/II (not on RSP-440)
  • Two EIA/TIA-232 RJ232 serial RJ-45 ports—one each for Console and Auxiliary modem ports, with Manufacturing Test connections to the backplane

Management Features

Two management LAN ports (MGT LAN 0, MGT LAN 1) are provided on the RSP/RP front panel. These are triple-speed RJ-45 connectors for use as out-of-band management ports.

An Auxiliary (AUX) port and Console port are also provided on the RSP/RP front panel. These are EIA/TIA-232 (also known as RS-232) asynchronous serial ports for connecting external devices to monitor and manage the system.

The RSP/RP card front panel also has a two synchronization (SYNC) timing ports that can be configured as BITS or J.211 ports. These ports provide connections for external timing and synchronization sources.

Alarm Connector

Each RSP/RP card drives a set of three alarm output contacts. Alarm circuitry on the RSP/RP card activates dry contact closures that are accessible through a nine-pin connector on the RSP/RP faceplate. Both normally open and normally closed contacts are available.

Serviceability

RSP/RP cards can be inserted or removed when adjacent (cabled) RSP/RP or line cards are installed. Compact Flash is serviceable without the need to remove the RSP card. Servicing the hard drive requires removal of the RSP/RP card.

RSP and RP Card Ejector Levers

Ejector levers are provided for inserting and removing the RSP/RP cards. The insertion and removal force of the card ejector levers is about 16 lbs (7.27 kg). Longer ejector levers are provided for the RSP/RP cards than for the line cards due to the higher pin count of the RSP/RP card.

Fabric Controller Card

On the Cisco ASR 9922 Router and Cisco ASR 9912 Router, the switch fabric has been moved to FC cards.

The switch fabric is configured as a single stage of switching with multiple parallel planes. The switch fabric is responsible for transporting packets from one line card to another but has no packet processing capabilities. Each fabric plane is a single-stage, non-blocking, packet-based, store-and-forward switch. To manage fabric congestion, the RP provides centralized Virtual Output Queue (VOQ) arbitration.

The switch fabric is capable of delivering 550-Gbps per line card slot. When five FC cards are installed in the chassis, the switch fabric is 4+1 redundant. When all seven FC cards are installed in the chassis, the switch fabric is 6+1 redundant. The switch fabric is fully redundant, with one copy of the fabric on each FC, and each FC carries enough switching capacity to meet the chassis throughput specifications.

Figure 1-27 shows the FC card.

Figure 1-27 FC Card

 

Figure 1-28 shows the front panel of the FC card. The front panel has a status LED, ejector levers, ejector lever release buttons, and mounting screws.

Figure 1-28 FC Card Front Panel

 

FC Card Ejector Levers

Ejector levers are provided for inserting and removing the FC cards from the backplane connectors. The insertion and removal force of the card ejector levers is about 16 lbs (7.27 kg). To release the ejector levers, push in the ejector lever release buttons.


Note Once any ejector lever release button is pushed in, the FC card must by physically removed and reinserted (OIR) to restart the FC card.

In addition to the line cards listed here, a SPA Interface Processor (SIP) and Shared Port Adapters (SPA) are supported on the Cisco ASR 9000 Series Routers. For information about these components, see the Cisco ASR 9000 Aggregation Services Router SIP and SPA Hardware Installation Guide .

Line Card Front Panel and Access Ports

Each line card drives a set of three alarm output contacts, one set for each of Critical, Major, and Minor. Alarm circuitry on the RSP/RP activates dry contact closures that are accessible through a nine-pin connector on the RSP/RP faceplate.

See the “Ethernet Line Cards” section for a description of each line card’s front panel indicators and their meaning.

Line Card Serviceability

Line cards can be inserted or removed when adjacent (cabled) RSP or line cards are installed.

Line Card Ejector Levers

Ejector levers are provided for inserting and removing line cards from the backplane connectors. Insertion and removal force of the card ejector levers is about 16 lbs (7.27 kg).

Power System

The Cisco ASR 9000 Series Routers can be powered with an AC or DC source power. The power system provides power for the cards and fan trays.

The power system is based on a distributed power architecture centered around a –54 VDC printed circuit power bus on the system backplane.

The –54 VDC system backplane power bus can be sourced from one of two options:

  • AC systems—AC/DC bulk power supply tray connected to the user 200 to 240 VAC +/- 10 percent (180 to 264 VAC) source
  • DC systems—DC/DC bulk power supply tray connected to the user Central Office DC battery source –48 VDC/–60 VDC (–54 VDC nominal)

DC output power from each power tray is connected to the router by two power blades that mate to the power bus on the backplane. The system backplane distributes DC power through connectors on the backplane to each card and the fan trays. Each card has on-board DC–DC converters to convert the –54 VDC from the distribution bus voltage to the voltages required by each particular card.

AC and DC Power Modules

Each AC or DC power tray houses up to four power modules.

  • The AC and DC power trays in the Cisco ASR 9006 Router and Cisco ASR 9904 Router provide N+1 redundancy.
  • The AC power trays in the Cisco ASR 9010 Router, Cisco ASR 9922 Router, and Cisco ASR 9912 Router provide N+N redundancy. The DC power trays provide N+1 redundancy.

The power trays drive a single output bus that delivers –54 V to all cards and fan trays that are plugged into the backplane.

  • To operate the Cisco ASR 9922 Router on AC power, four AC power trays should be installed, each with up to four power modules which are fed by a single-phase 220-V 20-A branch circuit. Eight power modules are enough to power a fully-populated chassis. Sixteen power modules are required for N+N redundancy. Fewer power modules can be used if the chassis is populated with fewer line cards.
  • To operate the Cisco ASR 9922 Router on DC power, four DC power trays should be installed, each with up to four power modules which are fed by separate pairs of redundant –48-V 60-A branch sources. Fifteen power modules are enough to power a fully-populated chassis. Sixteen power modules are required for N+1 redundancy. Fewer power modules can be used if the chassis is populated with fewer line cards.
  • To operate the Cisco ASR 9912 Router on AC power, three AC power trays should be installed, each with up to four power modules which are fed by a single-phase 220-V 20-A branch circuit. Six power modules are enough to power a fully-populated chassis. Twelve power modules are required for N+N redundancy. Fewer power modules can be used if the chassis is populated with fewer line cards.
  • To operate the Cisco ASR 9912 Router on DC power, three DC power trays should be installed, each with up to four power modules which are fed by separate pairs of redundant –48-V 60A branch sources. Eleven power modules are enough to power a fully-populated chassis. Twelve power modules are required for N+1 redundancy. Fewer power modules can be used if the chassis is populated with fewer line cards.

Cooling System

The Cisco ASR 9000 Series chassis is cooled by removable fan trays. The fan trays provide full redundancy and maintain required cooling if a single fan failure should occur.

In the Cisco ASR 9010 Router, the two fan trays are located one above the other below the card cage and are equipped with handles for easy removal.

In the Cisco ASR 9006 Router, the two fan trays are located above the card cage, left of center, and side by side. They are covered by a fan tray door hinged at the bottom, which must be opened before removing the fan trays.

In the Cisco ASR 9904 Router, a single fan tray is located in the rear, right side of the card cage and is equipped with a handle for easy insertion.

In the Cisco ASR 9922 Router, the two top fan trays are located between the top and middle cages, whereas the two bottom fan trays are located between the middle and bottom cages. The two bottom fan trays are inserted upside down compared to the two top fan trays. In the Cisco ASR 9912 Router, the two fan trays are located above the line card cage. Each fan tray holds 12 axial fans and includes a controller that reduces the speed of the fans when the chassis temperature is within limits, thereby reducing the generation of acoustic noise. The fan controller also senses and reports individual fan failures.

Cooling Path

  • The Cisco ASR 9010 Router chassis has a front-to-rear cooling path. The inlet is at the bottom front of the chassis, and the exhaust is at the upper rear. Figure 2-64 shows the cooling path of the Cisco ASR 9010 Router chassis.
  • The Cisco ASR 9006 Router chassis has a side-to- top-to-rear cooling path. The inlet is at the right side of the chassis, and the exhaust is at the upper rear. Figure 2-65 shows the cooling path of the Cisco ASR 9006 Router chassis.
  • The Cisco ASR 9904 Router has a side-to-side cooling path. Figure 2-66 shows the cooling path of the Cisco ASR 9904 Router chassis. The inlet is at the right side of the chassis, and the exhaust is at the left side.

If the router is installed in a 2-post 23-inch rack, air flow is circulated front-to-back. An optional air baffle accessory kit (ASR-9904-BAFFLE=) is available for mounting the router chassis in this configuration. For air baffle installation information, see:

Cisco ASR 9000 Series Aggregation Services Router Hardware Installation Guide

  • The cages of the Cisco ASR 9922 Router chassis have a front-to-rear cooling path. The inlet is at the front of the middle cage, and the exhaust is at the upper and lower rear. Figure 2-67 shows the cooling path of the Cisco ASR 9922 Router chassis.
  • The Cisco ASR 9912 Router chassis has a front-to-rear cooling path. The inlet is at the front of the RP/FC card cage, and the exhaust is at the upper rear. Figure 2-68 shows the cooling path of the Cisco ASR 9912 Router chassis.

Fan Trays

The Cisco ASR 9010 Router, Cisco ASR 9006 Router, and Cisco ASR 9912 Router contain two fan trays for redundancy (see Figure 2-69, Figure 2-70, Figure 2-72). The Cisco ASR 9904 Router contains a single fan tray for redundancy (see Figure 2-71). The Cisco ASR 9922 Router contains four fan trays for redundancy (see Figure 2-72). The fan tray has an LED indicator to indicate fan tray status. If a fan fails, it is possible to swap a single fan tray assembly while the system is operational. Fan tray removal does not require removal of any cables.


Note Due to air leakage, the chassis should not be operated with any of the fan trays completely missing. Replace any missing fan tray within five minutes. Any fan tray replacement should be performed when the chassis is back to room temperature.


Management and Configuration

The Cisco ASR 9000 Series Routers run IOS XR software and use the system manageability architecture of that operating system. The system management interfaces consist of the following three protocols running on the Cisco ASR 9000 Series Routers:

  • CLI—Command-line interface
  • XML—Extensible Markup Language
  • SNMP—Simple Network Management Protocol

By default, only CLI on the console is enabled.

Craft Works Interface (CWI), a graphical craft tool for performance monitoring, is embedded with the Cisco IOS XR software and can be downloaded through the HTTP protocol. You can use CWI to edit the router configuration file, open Telnet/SSH application windows, and create user-defined applications.
