BATTERY BACKUP UNIT

The ADTRAN Battery Backup Unit (BBU) is an optional device designed as a backup DC power supply
for the Total Access 900e Series.

Total Access 900e Series BBU (P/N 1175044L1/L2)

The BBU connects to the Total Access 900e Series through a 6-foot charge/discharge, 2-conductor wire
with a keyed modular plug (included with the BBU). The 1175044L1 BBU is a low profile wallmount
configuration. It can be rack mounted with the appropriate 19-inch (P/N 117547L1) or 23-inch
(P/N 1175048L1) rackmount adapter brackets. The 1175044L2 is an equivalent BBU with a hinged front
access door.
Features of the BBU, P/N 1175044L1/L2, include the following:
• No-spill battery design
• Compact wallmount or rackmount box
• Double BBU rack mounting available
• 7 Ahr battery (up to 8 hours of backup, depending on load)
• Modular plug (provides quick and easy installation)
• All mounting hardware included

Unpack and Inspect the Battery Backup Unit

Removing the Battery Backup Unit 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 Battery Backup Unit (P/N 1175044L1/L2) weighs in excess of 30 pounds.
Arrange for assistance when handling the BBU for mounting.
Batteries are retained and pre-wired 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.
