Cisco Cisco 5508 Wireless Controller Guía De Instalación

If you mid-mounted the chassis in a 2-post rack (see 

), you cannot use the chassis grounding 

pad or the provided grounding lug. You will need to ground the chassis in a different location on the 
chassis (such as the rear bracket mount holes using an M3 screw) using your own grounding lug. 

A grounding pad with two threaded M4 holes is provided on each side of the chassis for attaching a 
grounding lug.

To maintain the chassis height of one rack unit (RU), install the grounding lug on the right side of the 
chassis in the wire-up position, or on the left side of the chassis in the wire-down position.

When installing or replacing the unit, the ground connection must always be made first and 
disconnected last. Statement 1046

We recommend grounding the chassis, even if the rack is already grounded.

All power supplies must be grounded. The receptacles of the AC power cables used to provide power to 
the chassis must be the grounding type, and the grounding conductors should connect to protective earth 
ground at the service equipment.
