Grounding the Chassis
The chassis must be properly grounded prior to installing any chassis components or cards. The chassis and
the equipment rack/cabinet must be connected to the same ground point.
Failure to properly ground the chassis could result in personal injury and/or damage to the chassis and its
components.
Caution
There are two sets of grounding terminals located at the lower-rear of the chassis. Figure 4-8 shows the location
of these terminals and provides specifications for the appropriate lug and cable size.
Ground Cabling
The ASR 5500 is suitable for installation as part of the Common Bonding Network (CBN) in a network
telecommunications facility. It is not intended for installation in an Isolated Bonding Network (IBN).
Important
A 2-hole lug (Panduit LCD4-14A-L) is supplied for grounding the chassis. The lug must be crimped to the
end of a ground cable using Panduit crimp tool part number CT-720-1 (die color: gray, P29). The wire strip
length is 7/8-inch (22 mm),
The minimum, recommended stranded cable size is 4 AWG. the cable length to the site ground point should
not exceed 70 feet (21 m) one way.
The method of connection is: chassis -> lug -> flat washer -> nut (7/16-inch).
