Chapter 3 Installing the Cisco uBR7225VXR Router
Installing the Chassis in a Workbench or Tabletop Environment
Step 6 Insert the 10/32 x 3/8 slotted screws (two to a side) through the brackets and into the mounting strip (use
the top and bottom bracket holes, shown in Figure 3-2 on page 3-4, Figure 3-3 on page 3-4, Figure 3-4
on page 3-5, and Figure 3-5 on page 3-5). Using a 7/16-inch flat-blade screwdriver, tighten all the
screws.
This completes the procedure for installing the chassis in the rack. Proceed to the “Cabling” section on
page 3-13 to continue the installation.
Installing the Chassis in a Workbench or Tabletop Environment
The Cisco uBR7225VXR universal broadband router should already be in the area where you will install
it, and your installation location should already be determined. If not, refer to the “Site Requirements”
section on page 2-5.
When installing the router on a workbench or tabletop, ensure that the surface is clean and in a safe
location and that you have considered the following:
• The Cisco uBR7225VXR router requires at least 3 inches (7.72 cm) of clearance at the inlet and
exhaust vents (the right and left sides of the router).
• The Cisco uBR7225VXR router should be installed off the floor. (Dust that accumulates on the floor
can be drawn into the interior of the router by the cooling fans. Excessive dust inside the router can
cause overtemperature conditions and component failures.)
• There must be approximately 23.25 inches (59.06 cm) of clearance at the front, and 19 inches
(48.3 cm) at the back of the Cisco uBR7225VXR router for installing and replacing
field-replaceable units (FRUs), or accessing network cables or equipment.
• Make sure that blank cable interface line card and blank power supply filler plates are installed in
empty slots.
• The Cisco uBR7225VXR router will receive adequate ventilation (it is being installed in an enclosed
cabinet where ventilation is adequate).
• If you plan to install the cable-management bracket on the front of the chassis, set aside the
cable-management bracket and the four M3 x 6-mm Phillips panhead screws.
Warning
Do not stack the chassis on any other equipment. If the chassis falls, it can cause severe bodily injury
and equipment damage.
Statement 48
Complete the following steps to install the Cisco uBR7225VXR router on a workbench or tabletop:
Step 1 Remove any debris and dust from the tabletop or workbench, and the surrounding area. Also make sure
that your path between the router and its new location is unobstructed.
Step 2 On the chassis, ensure that all captive installation screws on the network processing engine, cable
interface line cards, and each power supply are tightened.
Warning
Two people are required to lift the chassis. To prevent injury, keep your back straight and lift with your
legs, not your back.
