Installing the Chassis on a Workbench or Tabletop
Complete the following steps to install the Cisco uBR7246VXR router on a workbench or tabletop:
Remove any debris and dust from the tabletop or workbench, and the surrounding area.
Step 1
On the chassis, ensure that all captive screws on the network processing engine, the I/O controller, the line cards, the
Step 2
clock card, and each power supply are tightened and the port adapter retention clip is in the locked position.
Place the Cisco uBR7246VXR router on the tabletop or workbench.
Step 3
Ensure that there is the appropriate amount of space around the router.
Step 4
Connecting the Chassis to Ground
Before connecting power and turning on the router, you must provide an adequate ground connection for your system. Two M5
ground receptacles provide a chassis ground connection for electrostatic discharge (ESD). The receptacles are located adjacent
to the lower power supply bay on the Cisco uBR7246VXR router chassis. See Figure 9.

Caution
The Cisco uBR7246VXR 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. Attachment of the chassis
ground to a headend, hub, or other interior ground system should be made with a 6-AWG, copper ground
conductor at a minimum.
Warning
Use copper connectors only. Statement 1025
Warning
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of
a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if
you are uncertain that suitable grounding is available. Statement 1024
