Chapter 3 Installing the Router
Supplemental Bonding and Grounding Connections
Installing the Chassis on a Tabletop or Flat Surface
Use the following procedure to install the Cisco XR 12404 Router on a tabletop 
or other stable flat surface.
Step 1
Move the router as close to the installation location as possible.
Step 2
With one person positioned at the front and rear of the chassis, lift the chassis off 
of the pallet and position the chassis on the flat surface.
Step 3
Secure the chassis to the flat surface to ensure 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 12404 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 12404 Router in a NEBS environment, you 
can choose to bypass these guidelines and rely on the safety earth ground 
connection supplied via the 5-15 15A North American plug to the AC-powered 
PEMs, and the main terminal block ground connection for DC-powered PEMs.

On Cisco XR 12404 Routers configured for AC-input operation, the AC PDU 
is equipped with a three-wire electrical grounding-type connector that accept 
three-wire, grounding-type AC power cords such as the power cords shipped 
with the router. This is a safety feature.
