The Cisco ASR 901 10G router provides a grounding point on the rear of the unit for a 2-hole lug.
To ensure the chassis ground connection that you provide is adequate, you need the following parts and
tools:

pressure for attaching the ground wire to the router.
• Crimping tool as specified by the ground lug manufacturer
• 16-AWG copper wire for the power cord
• Appropriate wire-stripping tools
Caution Before making connections to the Cisco ASR 901 10G router, ensure that you disconnect the power at
the circuit breaker. Otherwise it may result in severe injury to yourself, or damage to the router.
