Cisco uBR7225VXR Router Installation Checklist
A rack-mount and cable-management kit is included in the shipping container. The rack-mount brackets in the kit are for mounting the Cisco uBR7225VXR in standard, 19-inch-wide, 4-post equipment racks or telco-type equipment racks. The rack-mount brackets are not suitable for use with other racks, such as 23-inch telco racks. The cable-management bracket is designed to relieve the strain on interface cables that are installed on cable interface line cards in a Cisco uBR7225VXR router.
If you are installing an equipment shelf or using mounting hardware other than that supplied with the chassis, review the guidelines in the "Equipment Racks" section, then proceed to the "Cisco uBR7225VXR Router Chassis Rack-Mounting Options" section.
If you do not plan to install your Cisco uBR7225VXR router in an equipment rack, proceed to the "Installing the Chassis in a Workbench or Tabletop Environment" section.
To assist you with your installation and to provide a historical record of what was done, and by whom, use "Cisco uBR7225VXR Router Installation Checklist" section.

Cisco uBR7225VXR Router Chassis Rack-Mounting Options
The chassis mounts to two rack posts with brackets that attach to either the front, middle, or rear sides of the chassis. The inside width between the posts or mounting strips (left and right) must be at least 17.5 inches (44.45 cm).
Some equipment racks provide a power strip along the length of one of the mounting strips. Figure 3-1 shows a typical 4-post equipment rack with a power strip along one of the back posts. If your rack has this feature, consider the position of the strip when planning fastener points and ensure that you will be able to pull cable interface line card cables and other FRUs straight out of their respective slots.
The inlet and exhaust ports for cooling air are located on the right and left of the chassis, respectively, so multiple universal broadband routers can be stacked in a rack with little or no vertical clearance.
Note
We recommend the rear bracket mounting system for 4-post racks. This method enables you to keep cables from protruding too far out in front of the Cisco uBR7225VXR router and to simultaneously manage the cables at the front of the chassis with the cable-management bracket.
Figure 3-1 Typical 4-Post Equipment Rack Posts and Mounting Strips
Mounting options are as follows:
•
If you want the cable interface line card end (the front) of the chassis recessed in the rack, install the rack-mount brackets at the rear of the chassis in the orientation shown in Figure 3-2.
•
If you want the front of the chassis mounted flush with the front posts of the rack, install the rack-mount brackets at the front of the chassis in the orientation shown in Figure 3-3.
•
If you want the front of the chassis protruding out of the rack, install the rack-mount brackets at the front of the chassis in the orientation shown in Figure 3-4.
•
If you want the chassis in a telco-type rack, install the rack-mount brackets in the middle of the chassis in the orientation shown in Figure 3-5.

Warning The intra-building port(s) of the equipment or subassembly is suitable for connection to intra-building or unexposed wiring or cabling only. The intra-building port(s) of the equipment or subassembly MUST NOT metallically connect to interfaces that connect to the 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 4) 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. Statement 7005
|
Caution
To comply with GR-1089-Core intra-building lightning-immunity requirements, you must use shielded (screened) cable that is grounded at both ends.
Connecting Cable Interface Line Card Cables
The instructions for connecting the cables for each cable interface line card installed in the Cisco uBR7225VXR universal broadband router are contained in the cable interface line card installation document. Refer to the Cisco uBR7200 Series Interface Line Card Hardware Installation Guide at the following URL:
http://www.cisco.com/en/US/docs/interfaces_modules/cable/line_cards/installation/guide/mcxxfru.html
Console and Auxiliary Port Connection Equipment
The NPE contains the console and auxiliary ports. The console port is a RJ-45 receptacle for connecting a data terminal, which you use to configure the interfaces and bring up the Cisco uBR7255VXR router. The auxiliary port is a RJ-45 receptable for connecting a modem or the other DCE device (such as a channel service unit/data service unit [CSU/DSU]) to the router. (See Figure 3-12.)
Note
Both the console and auxiliary ports are asynchronous ports; any devices connected to these ports must be capable of asynchronous transmission. (Asynchronous is the most common type of serial device; for example, most modems are asynchronous devices.)

This completes the procedure for connecting AC-input power. Proceed to the "Powering On the Cisco uBR7225VXR Router" section.
Powering On the Cisco uBR7225VXR Router
After installing your Cisco uBR7225VXR universal broadband router and connecting cables, power on the universal broadband router as follows:
Step 1
Check for the following:
•
Each cable interface line card is inserted in its slot and its captive installation screws are tightened.
•
The network processing engine is inserted in to its slot and the captive installation screws are tightened.
Note
If the cable interface line card or the network processing engine is not properly seated or not fully locked into place, the Cisco uBR7225VXR router might enter a continuous restart loop. Make sure that the boards are seated and locked into position.
•
Hybrid fiber-coaxial (HFC) network coaxial cable is connected to the cable interface line cards.
•
A CompactFlash Disk is installed in a CompactFlash Disk slot in the front panel of the NPE-G1 or NPE-G2. Use only authorized Cisco provided CompactFlash Disks.
•
Each AC-input power cable is connected.
•
The console terminal is turned on.
Step 2
At the rear of the Cisco uBR7225VXR router, place the power switch on the power supply in the on (|) position. Repeat this step if a second power supply is installed. The power supply OK LEDs comes on.
Step 3
Listen for the fans; you should immediately hear them operating. In a very noisy environment, also look for air movement around the chassis to verify that the fans are operating. If the Cisco uBR7225VXR router was recently switched off, it might take up to 90 seconds for the power supply to restart and the fans to start operating.
Note
To facilitate headend installation, a Cisco uBR7225VXR universal broadband router equipped with at least one cable interface line card generates a downstream IF carrier when it starts running.
The downstream IF carrier will be present if a cable interface line card is properly installed and passes diagnostics, the router has been powered on for more than two minutes, the IF downstream shutdown command (no cable downstream if-output) has not been configured, or the Cisco uBR7225VXR router is not in ROMMON mode. The amplitude and shape of the downstream IF carrier will not change after the Cisco uBR7225VXR router is configured, unless a non-DOCSIS data rate is configured.
Step 4
Observe the initialization process. When the system boot is complete (a few seconds), the network processing engine begins to initialize the cable interface line cards. During this initialization, the LEDs on each cable interface line card behave differently (most flash on and off). The enabled LED on each cable interface line card goes on when initialization is complete, and the console screen displays a script and system banner similar to the following:

Configuring the Interfaces
When you start up the Cisco uBR7225VXR router for the first time, the system automatically enters the setup facility (also called the system configuration dialog), which determines which cable interface cards are installed. The setup facility prompts you for configuration information.
On the console terminal, after the system displays the system banner and hardware configuration, the following System Configuration Dialog prompt appears:
--- System Configuration Dialog ---
At any point you may enter a questions mark `?' for help.
Use ctrl-c to abort configuration dialof at any prompt.
Default settings are in square brackets `[]'.
continue with configuration dialog? [yes]:
You can proceed with the setup facility or exit from the setup facility, using the command interface to configure global (system-wide) and interface-specific parameters.
Caution
The setup
facility currently excludes cable-specific configuration commands. Upstream ports, therefore, have a default state of "shutdown" after the setup
facility is run. You must configure upstream parameters. For additional information, refer to the
Cisco uBR7200 Series Software Configuration Guide at the following URL:
http://www.cisco.com/en/US/docs/cable/cmts/ubr7200/configuration/guide/cr72scg.html
You do not have to configure the interfaces immediately; however, you cannot enable the interfaces or connect them to any networks until you have configured them.
Many of the cable interface line card LEDs do not come on until you have configured the interfaces. To verify correct operation of each interface, complete the first-time startup procedures and configuration, then refer to the document for each cable interface line card for LED descriptions and to check the status of the interfaces.
Your Cisco uBR7225VXR chassis installation is complete. To set up your cable network headend, proceed to Chapter 4 "Connecting the Cisco uBR7225VXR Router to the Cable Headend." To begin configuring your Cisco uBR7225VXR router, see the Cisco uBR7200 Series Software Configuration Guide at the following URL:
