Unpack and Inspect the BBU
After unpacking the BBU unit, inspect it for damage. If damage is noted, file a claim with the carrier; then
contact ADTRAN Customer Service.
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.
