Installing the Chassis in a Workbench or Tabletop Environment
The Cisco uBR7200 series 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 uBR7200 series router requires at least 3 inches (7.72 cm) of clearance at the inlet and
exhaust vents (the right and left sides of the universal broadband router).
•
The Cisco uBR7200 series 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
universal broadband 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 uBR7200 series router for installing and replacing
field-replaceable units (FRUs), or accessing network cables or equipment.
•
Blank port adapters, cable interface card, cable clock card (Cisco uBR7246VXR), and power supply
panels are installed.
• The Cisco uBR7200 series 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 brackets on the front of the chassis, set aside the
cable-management brackets and the four M4 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 uBR7200 series 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, the
I/O controller, cable interface line cards, the cable clock card, and each power supply are tightened and
the port adapter retention clip is in the locked position.
Warning
Two people are required to lift the chassis. To prevent injury, keep your back straight and lift with your
legs, not your back.
Statement 164
Step 3 Place the Cisco uBR7200 series router on the tabletop or workbench.
Step 4
Ensure that there is the appropriate amount of space around the router.
Step 5 Add the five rubber feet supplied with the accessory kit to the base of the chassis. Five indented circles
are provided on the base of the chassis to indicate the location to which the rubber feet can be added.
If you want to install a cable-management bracket on the Cisco uBR7200 series router, proceed to the
following section, “
Installing the Cable-Management Bracket on a Cisco uBR7200 Series Router in a
Workbench or Tabletop Environment .” Otherwise, proceed to the “Cabling” section on page 3-14 .
