Battery Backup Unit

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.
