DOCSIS-compliant bridging data operations. When installed and configured as a bridge, the Ethernet hub ports at the rear of the Cisco uBR905 router can be connected directly to PCs at the subscriber site. A maximum of four PCs can be directly connected to the router’s hub ports, or a maximum of 254 PCs can be connected if one of the four...
Routing Operations When configured as a router, the Cisco uBR905 can be connected directly to four PCs via the Ethernet hub ports at the rear of the router. One of the four Ethernet hub ports can also be connected to a standard 10BaseT Ethernet hub, which then connects additional computers or Ethernet devices at the site to a local area network (LAN).
Chapter 1 Product Overview Overview of the Cisco uBR905 Cable Access Router Features This section provides an overview of the Cisco uBR905 cable access router’s features, divided into the following categories: Basic Features • Configuration Options • Management Capabilities •...
Special web interface is automatically activated when the cable interface is not operational, • allowing users to easily supply configuration and status information to support engineers. LEDs on the front panel provide run-time status information on the Cisco uBR905 cable access • router, its interfaces, and its links.
By default, downloading a Cisco IOS configuration file disables the console port and erases all previously saved configurations. This default behavior prohibits configuration access at the remote site. Figure 1-3 depicts the front of the Cisco uBR905 cable access router. Figure 1-4 shows the rear of the unit. Figure 1-3...
Power Supply • See Appendix B, “Connector and Cable Specifications,” for the pinouts and cabling information for each of these connectors. For information on using the console port, see the Cisco uBR905 Software Configuration Guide. LED Descriptions The Cisco uBR905 router contains 11 LEDs on the front panel that provide information about the router’s status and network connections.
LED for custom applications or services. 1. These are the Cisco factory-default LED settings. Configuration control messages can be sent to the Cisco uBR905 cable access router through Simple Network Management Protocol (SNMP) set requests. Using Management Information Base (MIB) objects in the Cisco cable device MIB, the CMTS system administrator can define these LEDs to have other meanings.
Power Supply The Cisco uBR905 cable access router uses an external AC-input power supply. Refer to Table A-1 in Appendix A, “Technical Specifications,” for the AC-input power supply power specifications, including input voltage and operating frequency ranges.
Chapter 1 Product Overview Functional Overview Functional Overview This section provides a functional overview of the operation of the Cisco uBR905 cable access router, divided into the following categories: Initial Power On and Provisioning • Data Operations • Initial Power On and Provisioning The Cisco uBR905 cable access router ships from the Cisco factory ready to work in a DOCSIS-compliant bridging mode.
To ensure that subscribers obtain the exact services they have ordered, the Cisco uBR905 router arrives from the Cisco factory with a unique identifier (UID) that consists of a serial number and MAC address. These factory-assigned values are on a label at the bottom of the router; for convenience, these values are also in a barcode label that can be easily scanned for easy entry into the service provider’s...
If the DOCSIS configuration file specifies that the router must download a secondary Cisco IOS image and a Cisco IOS configuration file, the router uses TFTP to download the image and configuration files into its local memory. It then installs the new Cisco IOS image and runs the configuration file.
Interface (RFI) specification (SP-RFII01-990731 or later revision). After the Cisco uBR905 router goes online, it sends data traffic between the attached CPE devices and the network. The service provider typically uses DHCP to assign IP addresses to the CPE devices. The number of IP addresses each subscriber can obtain depends on the services purchased from the provider.
Upgrading the Software Image When Cisco IOS images are updated to new releases, the service provider can download them as needed to Cisco uBR905 routers installed in the field (based on the software licenses purchased). See the release notes for the router (listed in the “Related Documentation”...
Functional Overview Data Operations This section provides an overview of how data is transmitted to and from the Cisco uBR905 router across the cable system’s HFC network. Figure 1-7 illustrates a typical broadband data cable system, showing the network path between the Cisco uBR905 router and the CMTS headend equipment (Cisco uBR7200 series universal broadband router or other DOCSIS-compliant CMTS).
The Cisco uBR905 cable access router receives the upstream data from the CPE devices to which it is connected. It modulates this data for transmission on the coaxial cable system to the CMTS. The CMTS then routes the data to the appropriate destination (local server, Internet, and so forth) through its WAN interfaces.
Baseline Privacy Interface BPI security is defined by the DOCSIS 1.0 BPI specification (SP-BPI-I02-990319 or later revision). Both the CMTS and Cisco uBR905 cable access router must support BPI security and enable its use before this option can be used.
This chapter recommends general safety guidelines to follow and identifies requirements to meet before going to a subscriber site to install a Cisco uBR905 cable access router. It also lists the major agency approvals for the router. For additional safety and regulatory information, see Appendix C, “Regulatory Compliance and Safety Information.”...

(except for the four Ethernet LEDs and the ACT LED) briefly come on and then go off. As the self-test is executed, various LEDs light to reveal diagnostic progress and turn off when self-test is complete. The OK LED then blinks as the router completes self-test and boots a Cisco IOS image. When this is Step 2 finished, the OK LED comes on again.
From a PC connected to the Cisco uBR905 router, start the Internet browser program installed on the Step 2 Enter a URL of your choice in your web browser. If a URL is not known, use http://www.cisco.com to connect to Cisco’s CCO web site.
Installation problems with Cisco uBR905 routers are commonly due to the cable system and its topography. LEDs on the front panel of the Cisco uBR905 router reveal operational status and help you determine problem areas. See Figure 4-1 for the layout of the LEDs on the router’s front panel; see Table 1-1 on page 1-7 for a description of these LEDs.
The console port is initialized and the banner is output to the console port. Next, the Cisco uBR905 router performs a self-test on the low memory area of the DRAM. When this test starts, the LINK, DS, US, and MSG LEDs come on.
A memory or controller problem was detected while clearing the remaining DRAM. If all self-tests passed, the Cisco uBR905 router turns off all LEDs except OK and boots the Cisco IOS image stored in its Flash memory. The OK LED blinks during the boot process. If this LED does not start to blink, or if it continues blinking for more than ten minutes, see the “Power...
