NetVanta 6240/6250 Series HIG Unit Installation

Optional Battery Backup Unit (P/N 1175044L1/L2)

The ADTRAN battery backup unit (BBU) is an optional device designed as a backup DC power supply for

the NetVanta 6240/6250 Series. The BBU connects to the NetVanta 6240/6250 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 or

23-inch rackmount adapter brackets. The 19-inch rackmount adapter bracket part number is

P/N 1175047L1. The 23-inch rackmount adapter bracket part number is P/N 1175048L1.

Features of the BBU, P/N 1175044L1, 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 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.
