61181500L2-5B 3
Total Access 3000/3010 4-Pair Line Power Unit Installation and Maintenance Practice
CAUTION
Per GR-1089-CORE the Total Access 3000/3010 System is
designed and intended for installation as part of a Common
Bonding Network (CBN). The Total Access 3000/3010 System is
not designed nor intended for installation as part of an Isolated
Bonding Network (IBN).
CAUTION
Per GR-1089-CORE Section 9, the LPU does not have an internal
DC connection between –48 VR and frame ground. The LPU can be
installed in a DC-I (isolated) or DC-C (common) installation. For
installations where other cards or the host system have internal
connections between –48 VR and frame ground, the system would
be intended for deployment only in a DC-C installation.
CAUTION
The Total Access 3000/3010 Chassis frame ground terminal must
be connected to an earth ground to ensure that the front panel of
the LPU is properly grounded via the backplane connector.
NOTE
The powering ports of the LPU are classified as Type 1, 3, and 5, as
defined in Appendix B of GR-1089-CORE Issue 4, and meet the
lightning and power fault criteria with primary protectors that meet
any of the voltage limits of GR-974-CORE or GR-1361-CORE (for
example, carbon blocks, gas tubes, solid states).
NOTE
Current limiting protectors are not required.
NOTE
The LPU is designed to operate with a nominal operating voltage of
–48 VDC and a minimum operating voltage of –40 VDC. The LPU
will not be damaged by any steady state voltage below –56.7 VDC.

Installation
INSTALLATION
After unpacking the Total Access 3000/3010 LPU, inspect it for damage. If damage has
occurred, file a claim with the carrier then contact ADTRAN Customer Service.
Refer to “Appendix A, Warranty” for further information. If possible, keep the original shipping
container for returning the LPU for repair or for verification of shipping damage.
Installation Considerations
The number of LPUs installed in a system is significant, because overloading the Total Access
3000/3010 shelf with too many LPUs can cause the 20 amp current limit to be reached or
exceeded. An LPU producing 100 watts draws approximately 2.6 amps of current from the
Total Access 3000/3010 backplane. A fully loaded Total Access 3000/3010 shelf with
fourteen LPUs, each drawing 2.6 amps, would draw a total of 36.4 amps of current from the
Total Access 3000/3010 backplane. This is over the Total Access 3000/3010 shelf limit and
can cause the shelf fuse to blow. Therefore, it is recommended for safety reasons that no more
than seven LPUs be placed into a Total Access 3000/3010 shelf supplying power to the
DSLAMs with sub-full rate ADSL modules. If deployed in a configuration which requires
heavier loads, this maximum number of seven LPUs should be reduced to keep the Total
Access 3000/3010 backplane current at ≤ 20 amps.
The gauge and length of the wire used to transfer power is significant, because impedance
increases as the gauge and length of the wire increases and a greater impedance causes power
to be wasted during transmission.

Instructions for Installing the Module
The LPU installs in any two adjacent slots in a Total Access 3000/3010 chassis. The Total
Access 3000/3010 backplane connectors allow for either odd-even or even-odd slot insertion.
For installations residing in a CO or other controlled environment, fan cooling is not required.
However, a heat baffle is required directly above each Total Access 3000/3010 chassis. For
installations in remote locations, fan cooling is required for each two-stack arrangement of
Total Access 3000/3010 chassis.
If heat-generating equipment is installed below the Total Access 3000/3010 chassis, an
additional heat baffle may be required between the heat-generating unit and the bottom of the
Total Access 3000/3010 chassis.

Total Access 3000/3010 4-Pair Line Power Unit Installation and Maintenance Practice
CAUTION
Installations in a CO or other controlled environment require heat
baffles.
CAUTION
Installations in remote locations require fans.
NOTE
A maximum of seven LPUs with a nominal load of about 0.3 amps
can currently be inserted into the Total Access 3000/3010 shelf.
This limitation is due in part to the 30 amp fuse used with the
Total Access 3000/3010 shelf and because the Total Access 3000/
3010 backplane traces that supply the –48 VDC current cannot
handle more than a consistent 20 amps.
To install the LPU, perform the following steps:
1. If present, remove the Access Module Blank (P/N 1181953L1) from the appropriate access
module slot of the Total Access 3000/3010 chassis.
2. Pull the ejector latch, located on the lower left-hand side of the LPU front panel, from its
closed position.
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 module edges to fit in the lower and upper guide grooves for the access module
slot.
5. Slide the module into the access module slot. Simultaneous thumb pressure at the top
(above the
POWER LED) and at the bottom (below the electrostatic caution symbol) of the
module ensures that the module 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 self-test. Once the power up self-test is completed, the
front panel LEDs reflect the true state of the hardware. For LED descriptions, refer to “Front
Panel LEDs” on page 9.

Each LPU 96-pin edge connector inserts into a 96-pin backplane socket. The main edge
connector has pins for ground, alarms, provisioning, and card input power, plus output power
for the remote DSLAM. The daughter card has pins for ground and input power. Output power
is available on the 64-pin amphenol connectors on the Total Access 3000/3010 backplane.
The Total Access 3000/3010 chassis has eight 64-pin amphenols on the backplane. They are
labeled as follows:
• PAIR 1
• PAIR 2
• PAIR 3
• PAIR 4
• PAIR 5
• PAIR 6
• PAIR 7
• PAIR 8
As shown in Table 2, if the LPU inserts into slots 1 and 2 of the Total Access 3000/3010, the
power pairs appear at loop connections 1 through 4 of slot 1. If the LPU inserts into slots 9
and 10, the power pairs appear at loop connections 1 through 4 of slot 9. If the LPU inserts
into slots 20 and 21, the power pairs appear at loop connections 1 through 4 of slot 20, etc.
for a maximum allowable number of LPUs based on the Total Access 3000/3010 amperage
input limit.

Powering
The LPU operates on a –40 VDC to –56.7 VDC input voltage range.
The LPU uses about 10 watts of total power on the board, as follows:
• 2 watts are in the following input circuitries:
– input diodes (A and B diodes)
– inrush limiting Field Effect Transistor (FET)
–input inductor
–input fuse
• 1 watt is dissipated in the locally powered micro-controller and power supply components
• 7 watts are in the span supply
The output voltages are ±145 VDC and are provided on the four loop pairs as shown in
Table 3.
Table 3. Span Powered Pair Assignments
Total Access 3000/3010 Backplane Pair Number Module Edge Connector Pin Number
(Tip, Ring)
Pair 1 C6, B6
Pair 2 C5, C4
Pair 3 B5, A5
Pair 4 B4, A4
The LPU current and voltage limits are shown in Table 4.
Table 4. Current and Voltage Limits
Voltage Supply Minimum Current Maximum Current
290 VDC ±5% 0.004 amps 0.4 amps
–40 VDC to –56.7 VDC N/A 2.6 amps
NOTE
Both A and B inputs should be wired to limit the amount of current
flowing into the powering pins on the Total Access 3000/3010
backplane connector.

Installation
Deployment Guidelines
The number of powering pairs required for powering a DSLAM is dependent on the total resistance in the loop serving the powering pairs. For more information, refer to “Line Powering” in
the specific DSLAM Installation and Maintenance Practice.

Under Voltage The output voltage is too low. There is damage to the LPU that caused the
output voltage to be lower than 230 VDC
(between tip and ring).
Ground Fault There is a path to ground. There is a connection between one of the
output wires and ground.
Overload LPU is sourcing too much current. The output current is greater than 0.4 amps.
Under Current LPU is sourcing very low current. The LPU is not connected to any load or a
connected load is drawing less than 0.004
amps.

Most personal computers or laptops can run communications software that will emulate a
VT100 terminal. Windows programs such as Terminal or HyperTerminal are two such
examples in the Windows format, but there are many other adequate, commercially available
software packages, virtually all of which allow the PC or laptop to emulate a VT100 terminal.
Certain configuration items must be set on a PC or laptop to act as a VT100 terminal for the
Total Access 3000/3010.
