Attaching a Chassis Ground Connection
Connecting the Cisco ASR 1004 Router chassis to ground is required for all DC powered installations and
any AC powered installation where compliance with Telcordia grounding requirements is necessary.
The dual-lug chassis ground stud must be installed, the SIP and SPA must be fully inserted and screwed
in and earthed to prevent a potential hazard in a telecom line.
Caution
Have the recommended tools and supplies available before you begin this procedure.
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority
or an electrician if you are uncertain that suitable grounding is available. Statement 1024
Warning
Before you connect power or turn on power to your chassis, you must provide an adequate chassis ground
(earth) connection for the chassis. A chassis ground connector is provided on each Cisco ASR 1004 Router.
(See the image on the following section “Recommended Tools and Supplies.”) There is a grounding stud on
the side of the chassis and on the –48 VDC power supply (primary grounding stud).
The grounding wire is always the first to be installed or connected and the last to be removed or
disconnected.
Caution
Recommended Tools and Supplies
The following tools, equipment, and supplies necessary to connect the system ground to the chassis:
•
Phillips screwdriver
•
Dual-lug chassis ground component
•
Grounding wire
