Cisco ASR 907 Router Overview

The Cisco ASR 907 Router seven-rack unit router that belongs to the Cisco ASR90x family of routers. This router complements Cisco’s offerings for IP RAN solutions for the GSM, UMTS, LTE and CDMA. Given its form-factor, interface types and GigabitEthernet density the Cisco ASR 907 Router can also be positioned as a Carrier Ethernet aggregation platform.

The Cisco ASR 907 Router is a cost optimized, fully redundant, centralized forwarding, extended temperature, and flexible pre-aggregation router.

Cisco ASR 907 Router Features

The key feature of the Cisco ASR 907 Router is to increase per platform and rack-unit interface density, especially when combining multiple interface types such as Gigabit Ethernet (GE), TDM, 10GE, 40GE, and 100GE.

The Cisco ASR 907 Router has the following hardware features:

  • A larger service scale and higher throughput (400G) Route Switch Processors (RSP)—A900-RSP3C-400-W

  • One-port 100GE Interface Module (A900-IMA1C)

  • Two-port 100GE QSFP28 Interface Module (N560-IMA2C)


    Note
    After SSO, the packet rate increases and the packet count may vary.

  • Two-port 40GE Interface Module (A900-IMA2F)

  • 1200-Watt PSUs to power the new RSP modules.

The Cisco ASR 907 Router includes the following specific components:

  • Larger chassis—7 rack units in height while still maintaining a shallow depth and side-to-side airflow.

  • Larger fan-tray with removable dust filter.

  • New form factor and higher performance RSP—This high performance RSP has aggregate switching capacity of 480 Gbps in oversubscribed mode.

  • The backplane and the RSP together have the provision to support higher density 10GE modules like 8x10GE and 100GE modules.

  • Airflow baffle to allow a system to redirect air and allow front-to-back airflow for cooling.

  • Flexible I/O configurations through 16 hot pluggable interface modules (single width). For example, with RSP3-400-W in oversubscribed mode:

    • 16x10G + 2x100G + 80x1G

    • 48x10G

  • Metro ENET switching features along with TDM pseudowire support.

  • Network processor provides flexibility to off-load control plane CPU processing for select OAM and management packets (for example, CCM, BFD, LBM).

  • Flexible ENET processing through table-driven packet processing engines.

  • On-line insertion or removal (OIR) of all FRUs except GPS module, while the system is operational.

  • Power supply (1+1)—Support for both, AC and DC power supplies. A single power supply can support full system load. If there are two PSUs in the system, they work in a load-sharing mode.

  • Fully redundant system with redundant combined control plane and data plane (excluding interfaces), timing support, power supplies, and fans.

  • Active and standby support of redundant control plane and data plane, and timing

  • Intrachassis IOS redundancy (requires both RSPs).

  • Stateful-switchover (50 ms) between active and standby RSPs (for protocols that are supported by IOS).

  • In-service software upgrade (ISSU) supported with same RSPs.

  • Timing support for receipt and distribution of network frequency and time including SyncE, BITS, 1PPS/10MHz I/O, IEEE 1588-2008, and NTP.

  • Support for ENET OAM.

  • T1/E1 line protection compliant with NEBS GR-1089.

GNSS Module (A900-CM-GNSS)

The GNSS module is present on the RSP. It is a pluggable module that allows direct interface with the external antenna.


Note

Using a single GPS antenna input for both RSPs requires usage of external splitters.


Warning

To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023


Note

The GNSS module is not hot swappable.

GNSS Module RF Input Requirements

  • The GNSS module requires an active GPS/GNSS antenna with built-in Low-Noise Amplifier (LNA) for optimal performance. The antenna LNA amplifies the received satellite signals for two purposes:
    • Compensation of losses on the cable
    • Lifting the signal amplitude in the suitable range for the receiver frontend

    The Amplification required is 22dB gain + cable/connector loss + Splitter signal loss.

    The recommended range of LNA gain (LNA gain minus all cable and connector losses) at the connector of the receiver module is 22dB to 30dB with a minimum of 20dB and a maximum of 35dB.

  • GNSS module provides 5V to the active antenna through the same RF input.
  • Surge requirement:

    • GNSS modules have built-in ESD protections on all pins, including the RF-input pin. However, additional surge protection may be required if rooftop antennas are being connected, to meet the regulations and standards for lightning protection in the countries where the end-product is installed.

    • A lightning protection must be mounted at the place where the antenna cable enters the building. The primary lightning protection must be capable of conducting all potentially dangerous electrical energy to PE (Protective Earth).

    • Surge arrestors should support DC-pass and suitable for the GPS frequency range (1.575GHz) with low attenuation.

  • Antenna Sky visibility:
    • GPS signals can only be received on a direct line of sight between antenna and satellite. The antenna should see as much as possible from the total sky. For proper timing, minimum of four satellites should be locked.

      Note
      The antenna terminal should be earthed at the building entrance in accordance with the ANSI/NFPA 70, the National Electrical Code (NEC), in particular Section 820.93, Grounding of Outer Conductive Shield of a Coaxial Cable.

  • Use a passive splitter if more than one GNSS modules are fed from a single antenna.

Power Supply Features

The Cisco ASR 907 Router supports 1200 W DC or AC power supplies on all the three PSU slots.

The AC and DC power supplies support:

  • -40.8 VDC to -72 VDC

  • 85 VAC to 264 VAC

The power supplies are hot-swappable. They are enclosed to prevent exposure to high voltages, and therefore, no power cable interlock is required. However the power supplies are automatically shut down when removed from the chassis. The power supplies are rated to deliver 1200W (~100A at +12VDC) to the other FRUs in the system and are rated for operation at 5ºC above the chassis operating temperature.

See the below tables for the AC and DC power supply specifications.

For more information about installing the Cisco ASR 907 Router power supplies, see Installing the Power Supply.

Redundancy

The Cisco ASR 907 Router chassis includes a slot for an optional redundant power supply. The redundant power supply option provides a second power supply to ensure that power to the chassis continues uninterrupted if one power supply fails or input power on one line fails. Redundancy is supported either with identical power supplies or a combination of AC and DC power supply. The Cisco ASR 907 Router supports current sharing between the power supplies.

If you install a redundant power supply on the Cisco ASR 907 Router, we recommend that you connect each power supply to a separate input power source in order to ensure that the router maintains power in the event of a power interruption caused by an electrical failure, a wiring fault, or a tripped circuit breaker.

Dying Gasp

The Cisco ASR 907 Router DC power supply does not support the Dying Gasp feature.

Status LEDs

LEDs are also provided on each power supply to indicate the status of the input power and the health of the power supply. For more information about the LEDs on the Cisco ASR 907 Router, see Troubleshooting.

Fan Tray

The fan tray module supported on the router is:

  • A907-FAN-E

The fan tray has:

  • Four dual rotor fans—for the PSU area cooling
  • 12 fans (three columns for four fans)—60x60x38mm fans for the RSP and IM area

The fan tray has the following hardware features:

  • It provides side-to-side forced air cooling
  • It provides redundant fans
  • It is field replaceable
  • It contains status LEDs

For more information about air flow guidelines, see Air Flow Guidelines. For instructions on how to install the fan tray, see Installing the Fan Tray . For a summary of the LEDs on the fan tray, see LED Summary .

Dust Filter (A907-FAN-F)

The dust filter on the fan tray is a quadrafoam 45PPI filter which is 85 percent dust resistant. For installing the fan filter, see Removing and Replacing the Dust Filter section.

Air Plenum (A907-F2B-AIR-U)

Air Plenum or air baffle assembly is used to change the air flow pattern of the unit. When the router is installed with the plenum, the air flow pattern is changed from side-side to front-back. The air flow front-back pattern provides a rack installation bay with a cool front zone and hot rear zone. For installing the plenum, see Installing the Chassis in the Air Plenum section.


Note
When the air plenum and the fan filter are installed in the chassis, the system operating temperature is 55º C.

RSP Modules

The Cisco ASR 907 Router is designed to use up to two RSP modules to handle the data plane, network timing, and control plane functionalities for the router. The RSP configuration allows you to use Cisco IOS software to control chassis management, redundancy, external management, and system status indications on the router.

RSP features include:

  • Loading software onto processor-based interface modules
  • Redundant RSP management—The RSP manages detection of RSPs, exchange of health and status information, role negotiation, function for detection, health and status exchange, role negotiation
  • Packet processing
  • Traffic management, including buffering, queuing, and scheduling, Ethernet MAC functions
  • Network clocking functions including phase and time-of-day for BITS, 1 PPS, 10 MHz, and 1588 PTP clock references.
  • Storage of software images, system configuration, SysLog
  • PTP packet processing including IEEE 1588-2008 for recovering network timing (frequency, phase, and time) from upstream PTP clocks, for generating PTP frequency and phase references as inputs to the SETS, and for distributing them to downstream PTP clocks
  • External management interfaces (RS232 console, management ENET, USB console, USB storage) and system status LED indicators

Supported RSPs

Effective Cisco IOS-XE Release 3.16, the Cisco ASR 907 Router supports the following RSP:

  • A900-RSP3C-400-W—Provides 8 GB of SDRAM, 20 Mb of TCAM memory on every ASIC.

8 The restrictions for Cisco N560-IMA-8Q/4L interface module is same as that of Cisco A900-IMA8Z interface module.

RSP Redundancy

The Cisco ASR 907 Router chassis includes two RSP slots to allow for redundant RSPs. When the router uses redundant RSPs, one RSP operates in the active mode and the other operates in the hot standby mode. Removal or failure of the active RSP results in an automatic switchover to the standby RSP.


Note
If you are using redundant RSPs, both the RSPs must be of the same type because a mixed configuration of two different RSP types is not supported.

Network Timing Interfaces

The RSP supports the following network timing interfaces:

  • BITS input/output port—RJ48 jack

  • 1 PPS input and output—Mini coax connectors

  • 2.048 or 10 MHz input and output—Mini coax connectors

  • Time of Day (ToD) input/output port and 1 PPS input port—Shielded RJ45 jack

Network timing interfaces support redundancy in a redundant RSP configuration. Network timing interfaces on a redundant RSP remain in operation while the RSP is in hot standby mode.

Figure 11. 2-Port 100 Gigabit Ethernet Interface Module (2X100GE)

For information on supported QSFP modules, see Cisco ASR 900 Series Interface Modules Data Sheet.

Limitations of 2X100 GE IM

After any QSFP28 100G optics is inserted, it takes approximately 10 seconds for the optics to be detected and the link to come up. We recommend this time delay for complete initialization and operation.

After inserting the cable or after unshutting the 100G interface, the 100G link may take approximately about 2 seconds to come up.


Note

QSFP-100G-SR4-S and QSFP-100G-LR4-S are the supported optics for 2X100GE IM for the release 16.11.1.

ASR 900 1-Port OC-192 or 8-Port Low Rate CEM 20G Bandwidth Interface Module (A900-IMA1Z8S-CXMS)

The ASR 900 1-Port OC-192 or 8-Port Low Rate CEM 20G Bandwidth Interface Module is a cost-effective interface module (IM) that supports CEM and Multiservice Gateway features on the OCn interfaces.


Note

The Multiservice Gateway features are not supported on this IM on Cisco IOS XE Release 16.12.1.
Figure 24. CEM and iMSG Interface Module

The ASR 900 1-Port OC-192 or 8-Port Low Rate CEM 20G Bandwidth Interface Module, 20G IM supports eight SFP optical interfaces supporting at OC-3/OC-12/OC-48/1G rates and a single SFP+ optical interface supporting at OC-192/10G.

This IM operates in two modes:

  • 20G mode; uses two XFI lanes towards the system

  • 10G mode; uses single XFI lane towards the system

The benefits of this IM are:

  • Improves backplane efficiency

  • Increases system capacity

  • Increases client flexibility

The most important feature of the ASR 900 1-Port OC-192 or 8-Port Low Rate CEM 20G Bandwidth Interface Module, 20G IM is it provides more flexibility from the interface, which allows you to configure any interface speed on the OCn port irrespective of the IM bandwidth. The bandwidth restriction comes into effect only when the circuit is configured.

For example, you can configure the SFP+ port as an OC-192 and the other eight optical ports as OC-48 to have the total interface speed of 30G. However, if you configure only one STS-1 HO CEP on each port that will take only 9xSTS-1, which is equivalent to 500 Mbps (9 x 52Mbps x1.06) of the backplane traffic.

Restrictions

  • On the port capable of OC-192 speed, lower speed such as, OC-3, OC-12, or OC-48 are not supported.

  • Separate licenses are required for every OC-3, OC-12 ports, OC-48, and OC-192 ports.

8-Port 10G SFP+ Single-Rate Interface Module (N560-IMA-8Q/4L)

The 8-Port 10G SFP+ Single-Rate Interface Module (N560-IMA-8Q/4L) is a single-width-single-height IM. The 8 ports of the IM are split into two modes of 4 ports each called as quads.

The single-rate optic is supported and can support on 10G.

Figure 27. Cisco N560-IMA-8Q/4L Interface Module

The interface module has a maximum power draw value of 50 W.

Temperature Sensor

The Cisco ASR 907 Router has a temperature sensor to detect ambient overtemperature conditions inside the chassis. The operating temperature range is between –40 C to +65 C. Temperatures outside this range are reported to the processor as an interrupt, and the software takes action to generate the appropriate alarms.

Interface Numbering

Following is an explanation of the slot or port numbering:

  • The numbering format is Interface type slot or interface number . Interface (port) numbers begin at logical 0 for each interface type.
  • Interface module slots are numbered from bottom to top, with logical interfaces on each module numbered from left to right. Interfaces are hard-wired. Therefore, port 0 is always logical interface 0/0, port 1 is always logical interface 0/1, and so on.

Following is the A900-RSP4 port numbering:

  • For IM N560-IMA2C the port numbering is HundredGigE — 0/0/0/0 - 0/0/0/1

  • For IM A900-IMA8Z the port numbering is TenGigE — 0/0/0/1 - 0/0/0/7

  • For IM A900-IMA8CS1Z-M the port numbering is:

    • GigE — 0/0/0/0 - 0/0/0/15

    • TenGigE — 0/0/09/16

The following commands display the active RP slot number. The interface module is referenced as 1/x instead of 0/x:

  • show diag all eeprom detail
  • show platform software trace message iomd
  • show platform software agent iomd
  • show platform software peer shell-manager brief
  • show platform software peer chassis-manager
  • show platform software memory iomd
  • set platform software trace iomd
