SUBJECT TO ELECTROSTATIC DAMAGE OR DECREASE IN RELIABILITY.
HANDLING PRECAUTIONS REQUIRED.
This job aid provides information for the installation, function, and operational use of the ADTRAN® 3192 Line Power Unit (LPU). The LPU (P/N 1181501L2) is designed to provide power for the Total Access® 1124/1148 Line Powered Digital Subscriber Line Access Multiplexer (DSLAM).
Each ADTRAN LPU provides up to 100 watts of power to an associated DSLAM on a
Each LPU occupies any two adjacent slots in a 3192 shelf. Slots not occupied by an LPU can house standard channel cards. Total slot population is limited by the maximum input current of the 3192 shelf.
The LPU receives
The total power wiring pair requirement is based on transmission distance to the remote location.
Power input to the LPU is fused at 4.0 amps; Tip and Ring power output is fused at 1.5 amps each. Fuses are not replaceable.
After unpacking the unit, inspect it for damage. If damage is noted, file a claim with the carrier, and then contact ADTRAN. For more information, refer to the warranty.
The LPU installs in any two adjacent slots in a 3192 shelf.
WARNING: Adhere to static discharge precautions when handling circuit cards.
To insert the LPU, perform the following steps:
1.If present, remove the blank panel from the appropriate module slot of the chassis.
2.Pull the ejector latch, located on the lower
3.Hold the LPU by the front panel while supporting the bottom edge of the module with the ejector latch opened to engage the chassis edge.
4.Align the LPU card edges to fit in the lower and upper guide grooves for the access module slot.
5.Slide the LPU into the module slot. Simultaneous thumb pressure at the top (above the POWER LED) and at the bottom (below the electrostatic caution symbol) of the front panel ensures that the LPU is firmly positioned against the backplane of the chassis.
6.Secure the LPU in place by pushing in on the ejector latch.
Upon installation, the LPU initiates a
Five front panel LEDs provide status for the LPU. The POWER LED is green; its normal condition is on. All other LEDs are red; their normal condition is off. LEDs are as follows:
