Installing the Chassis Ground Connection

Before you connect the power or turn on the power to the Cisco ASR 903 Router, you must provide an
adequate chassis ground (earth) connection to your router.
This section describes how to ground the Cisco ASR 903 Router chassis. The router provides two
locations for attaching a 2-hole grounding lug according to the rack-mounting brackets you use to install
the router. The Cisco ASR 903 Router supports the following rack-mounting types:
