3 Site Preparation Check the following: • Site is capable of maintaining an ambient temperature of 32 to 104 degrees Fahrenheit • Site power is available and adequate • Cabling requirements (type, distance) • Rack-mounting requirements (working space, proper airflow) Site Environment 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.
Power Connection Guidelines for DC-Powered Systems The DC-input power supply allows the Cisco uBR7246VXR router to operate on either -48 or -60 VDC systems. Warning Connect the unit only to DC power source that complies with the safety extra-low voltage (SELV) requirements in IEC 60950 based safety standards. Statement 1033 The Cisco uBR7246VXR router (using DC power supplies) is not shipped with wiring to connect to a DC power source.
4 Installing the Chassis Rack-Mount Installation Guidelines • Allow sufficient clearance around the rack for maintenance.You need 36 in. (91.44 cm) of clearance to remove and replace system components. • If the Cisco uBR7246VXR chassis is the only unit in a rack, mount the chassis at the bottom of the rack. Use the rack-mount kit that comes with the chassis. • Always place the heavier equipment in the lower half of the rack.
Verifying Contents After Unpacking Power cables, manuals, and other additional items are packaged in separate boxes. After you have unpacked the system, verify that you have received all the required components and documentation. Step 1 Using the packing list as a guide, verify that you have received everything that is listed, including the following: a. System hardware documentation and software documentation (if ordered). b.
Attach the Rack-Mount Brackets to the Rear of the Chassis To install the rack-mount brackets on the chassis for a rear rack-mount configuration, complete the following steps: Step 1 Locate the threaded holes in the rear sides of the chassis. Step 2 Align the first rack-mount bracket to the threaded holes in the right side of the chassis. See Figure 4.
Installing the Rack-Mount Brackets so the Front of the Chassis Is Flush with the Rack 103557 Figure 5 Rack-mount bracket Rack-mount bracket Note Installing the Rack-Mount Brackets so the Front of the Chassis Protrudes Out of the Rack 103558 Figure 6 You cannot use the cable management bracket in this configuration.
Installing the Rack-Mount Brackets in the Middle of the Chassis for Open or Relay-Type Racks Rack-mount bracket Rack-mount bracket 103561 Figure 7 Installing the Cable-Management Brackets If you are rack-mounting the chassis at the rear or middle of the chassis, both rack-mount brackets and the cable-management bracket must be installed before the chassis is installed in the rack. See Figure 8 for cable management bracket locations.
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 Caution Because the brackets support the weight of the entire chassis, be sure to use all of the required slotted screws to fasten the two rack-mount brackets to the rack posts.
Installing the Chassis on a Workbench or Tabletop Complete the following steps to install the Cisco uBR7246VXR router on a workbench or tabletop: Step 1 Remove any debris and dust from the tabletop or workbench, and the surrounding area. Step 2 On the chassis, ensure that all captive screws on the network processing engine, the I/O controller, the line cards, the clock card, and each power supply are tightened and the port adapter retention clip is in the locked position.
Complete the following steps to connect the Cisco uBR7246VXR router chassis to ground: Step 1 Ensure that there is no power going to the router. Step 2 Strip approximately 0.75 in (2 cm) of shielding from the wire. Step 3 Insert the stripped end of the wire into the open end of the ground lug, and crimp the lug. Step 4 Slide a segment of heat shrink tubing over the exposed grounding lug and wire connection. Step 5 Shrink the tubing in place, using a suitable heating device.

DC Power Supplies Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement 1003 Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046 Warning A readily accessible two-poled disconnect device must be incorporated in the fixed wiring.
Warning The illustration shows the DC power supply terminal block. Wire the DC power supply using the appropriate wire terminations at the wiring end, as illustrated. The proper wiring sequence is ground to ground, positive to positive (line to L), and negative to negative (neutral to N). Note that the ground wire should always be connected first and disconnected last.
Caution If the port adapters, cable interface line cards, network processing engine, or I/O controller are not properly seated or not fully locked into place, the Cisco uBR7246VXR router might enter a continuous restart loop. f. A flash memory card is installed in its Personal Computer Memory Card International Association (PCMCIA) slot. g. Each AC-input power cable is connected and secured with the cable-retention clip. h.
Resolve the problem if possible or contact the Cisco Technical Assistance Center. For Cisco TAC contact information see the “Obtaining Technical Assistance” section on page 21.
This message indicates that the system has detected an overtemperature condition or power out-of-tolerance condition inside the chassis. The shutdown message could also indicate a faulty component or temperature sensor. Before the system shuts down, use the show environment or show environment table command to display the internal chassis environment.
