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:
• EIA 19-inch rack—Attach the grounding lug to the rear of the router, as shown in the figure below.
