Prepare for Installation (continued)
Verify the Following Before Going to a Subscriber Site:
Item Description
General
Coaxial cable is run from the CATV trunk to the subscriber building or residence.
Note: Cisco recommends that a dedicated (new) CATV cable drop be run from the grounding block
directly to the Cisco uBR924 cable access router. If such a drop is not available, careful qualification of
existing cable is often necessary. Cable ground should be connected to the grounding system of the
building or residence as close to the point of cable entry as practical. For the United States, refer to NEC
section 820-40 guidelines for proper grounding.
The site is characterized from the headend to support upstream transmission and meets DOCSIS upstream
and downstream RF requirements. Follow procedures in the NCTA Recommended Practises for
Measurements on Cable Television Systems.
All required headend routing and network interface equipment is installed, configured, and operational.
This includes all routers, servers (DHCP, TFTP, and TOD), network management systems, and/or other
configuration or billing systems.
DHCP, Cisco IOS images, and DOCSIS configuration files have been created and pushed to appropriate
servers such that each Cisco uBR924 cable access router, when initialized, can transmit a DHCP request,
receive an IP address, obtain TFTP and TOD server addresses, and download a DOCSIS configuration file
(and/or updated software image) in compliance with DOCSIS.
Note: The router’s cable MAC address found on a label at the bottom of the unit ensures each unit
downloads only the file(s) intended for that router.
PCs at each subscriber site meet the minimum computing requirements and that TCP/IP and DHCP
operating modes are enabled. Cisco recommends that the PC have a 486 DX 33 MHz processor minimum
configuration (a 75 MHz Pentium or greater processor is recommended); 16 MB of RAM; Windows for
Workgroups for 486-based PCs and Windows 95 (or higher) for Pentiums; an Internet browser; and a
pre-installed Ethernet Network Interface Card (NIC) with DHCP enabled.
Note: This recommendation is for Internet access in general. Other operating systems and hardware
platforms of comparable capability are also supported.
IP
Telephony
Telephones at each subscriber site support touch-tone dialing; rotary dialing is not supported.Wiring is in
place at subscriber sites supporting multiple telephones and fax devices per VoIP telephone line.
Fax devices—standard Group III and computer-based Group III machines up to 14,400 baud—are
supported in Cisco IOS Release 12.0(5)T or higher.
Note: In general, fax/modem cards are not supported over Voice over IP (VoIP) links. Contact your
network management, provisioning, or operations team to determine what your network supports.
A regular voice grade line and RJ-11 modular jack (USOC code) is installed near the location to install the
router for all sites that support backup PSTN connections.

Install the Router and Connect Cables
The Cisco uBR924 cable access router is DOCSIS-based and interoperates with any DOCSIS-qualified CMTS.
TherouterusesCiscoIOSRelease 12.0(4)XI,12.0(5)T,or highersoftware,andsupports manyadvancedrouting
features. The router can be configured to support data, voice, or a mixture of data and voice.
Note: The router ships from the Cisco factory with the console port enabled and a software image that
supports data only. Based on your licensing agreement, you can use Cisco Connection Online (CCO) to
download an image or images that support voice and/or other operating modes. Downloading a Cisco IOS
image disables the console port by default and erases all saved configurations.
Safety Information
Note: Before installing equipment, review the Regulatory Compliance and Safety Information for the
Cisco uBR924 Cable Access Router publication and follow all guidelines. Also refer to the Cisco uBR924
Cable Access Router Installation and Configuration Guide for more in-depth instructions.
Warning Only trained and qualified personnel should be allowed to install or replace this equipment.
Install the Router
Step 1 Place the router on a stable, flat surface close to the CATV drop connection and all devices to be
connected at the subscriber site.
Step 2 Make sure the bottom, sides, and rear of the router are clear and well-ventilated to prevent the unit
