Unpack and Inspect the BBU

Removing the BBU covers could allow batteries to fall out.
After unpacking the BBU unit, inspect it for damage. If damage is noted, file a claim with the
carrier; then contact ADTRAN Customer Service.
The BBU (P/N 1175044L1/L2) weighs in excess of 30 pounds. Arrange for
assistance when handling the BBU for mounting.
Batteries are retained and prewired in the BBU in a specific pattern. Battery position is
maintained by foam spacers press-fitted against the housing walls. Removing batteries or
disconnecting wires compromises correct reassembly and should not be attempted.
The BBU should only be used in specified ADTRAN applications.
This device complies with Part 15 of the FCC rules. Operation is subject to the following two
