Installing the Chassis on a Tabletop or Flat Surface

Use the following procedure to install the Cisco XR 12406 router on a tabletop or
other stable flat surface.
Step1 Move the router as close to the installation location as possible.
Caution Do not lift the chassis by the blower module handle. This handle is designed to
support only the weight of the blower module.
Step2 With one person positioned at the front of the chassis and one at the rear, lift the
chassis off the pallet and position the chassis on the flat surface.
Step3 Secure the chassis to the flat surface to ensure that it does not fall off.
You can use the same mounting hardware that secured your router to the shipping
pallet to secure the chassis to the flat surface.
Supplemental Bonding and Grounding Connections
Before you connect power or turn on your Cisco XR 12406 router, you must
provide an adequate system ground for the router. The equipment grounding
should be in accordance with local and national electrical codes.
If you are not installing the Cisco XR 12406 router in a NE BS environment, you
can choose to bypass these guidelines and rely on the safety earth ground
connection supplied using the 5-15 15A North American plug to the AC-powered
PEMs, and the main terminal block ground connection f or DC-powered PEMs.
•On Cisco XR 12406 routers configured for AC-input operation, the AC PDU
is equipped with a three-wire electrical grounding-type c onnector that accept
three-wire, grounding-type AC power cords such as the power cords shipped
with the router. This is a safety feature.
