Card Slot and Logical Interface Numbering The cable interface line card slots maintain the same slot number regardless of whether other cable interface line cards are installed or removed. However, when you move a line card to a different slot, the logical interface number changes to reflect the new slot number.
Temperature and Humidity Requirements Table 1 Table 2 list the nominal operating and non-operating environment requirements. Any measurements that approach the minimum or maximum of a range indicate a potential problem.

Installation Tools and Equipment The tools and equipment listed below are recommended as the minimum necessary to install the Cisco uBR7225VXR router. Other equipment may include test equipment to check electronic and optical signal levels, power levels, and communications links.
Table 3 Ethernet and Fast Ethernet Maximum Transmission Distances Transceiver Speed Cable Type 100 Mbps Category 6 100 Mbps 100 Mbps Single mode fiber (SMF) 1000 Mbps MMF and SMF For details about cabling specifications, refer to the Network Processing Engine and Network Services Engine Installation and Configuration guide at the following URL: http://www.cisco.com/en/US/products/hw/cable/ps2217/prod_installation_guides_list.html A shielded CAT5e cable must be used to meet EMI Class A certification.
Installing the Chassis The Cisco uBR7225VXR routers may be installed on a tabletop or rack-mounted. A rack-mount kit ships from the factory with each router. The rack-mount kit includes the hardware used to mount the router in a standard 19-inch equipment rack or Telco-type rack.

(only one set is available) to align the bracket to the threaded holes in the sides of the chassis. The Cisco uBR7225VXR chassis has only five holes in the rack-mount brackets. You must use four holes for the front Note rack-mount and middle rack-mount, and five holes for the rear mount.
Installing the Chassis in the Rack Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security. Statement 1017 Because the brackets support the weight of the entire chassis, be sure to use all of the required slotted screws to Caution fasten the two rack-mount brackets to the rack posts.
Statement 1024 Caution The Cisco uBR7225VXR router installation must comply with all applicable codes and is approved for use with copper conductors only. The ground bond fastening hardware should be of compatible material and preclude loosening, deterioration, and electrochemical corrosion of hardware and joined material.
Step 6 Connecting the Chassis to Power The Cisco uBR7225VXR router is equipped with AC-input power supplies. For more information on the supported power supplies, see the Cisco uBR7225VXR Universal Broadband Router Hardware Installation Guide at the following URL: http://www.cisco.com/en/US/docs/cable/cmts/ubr7200/ubr7225vxr/installation/guide/uBR7225VXR_HIG.html Note The DC-input power supply is not supported on the Cisco uBR7225VXR router.
Power switch Handle Plug the power cable into the AC connector of the power supply. Step 2 For additional AC power cable strain relief, secure the cable to the power supply handle by inserting a nylon cable tie Note through the hole in the handle and around the cable. Plug the AC power supply cable into the AC power source.
Step 2 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.
