Ground interface

The Alcatel-Lucent B25 RRH4x30 is to be grounded via one two-hole lug. The
B25 RRH4x30 has one bare metal grounding location on the bottom of the
B25 RRH4x30 with two M6 tapped holes. The M6 holes are 19 mm apart and intended
for use with a two-hole lug. A two-hole lug and M6 mounting screws are provided in the
Warrantee Eligibility System (WES) kit (part number 301022679, also known as the
ground lug kit), which must be ordered separately. The RRH outdoor grounding kit
(301080628) includes a 35 mm

(2 AWG) ground wire, C-tap, and hardware for this

connection. The RRH outdoor grounding kit is also required and must be ordered
separately.

The following figure shows the location of the grounding points on the bottom of the
