Total Access 3000/3010 T1-OR/NIU Installation and Maintenance Practice

4 61181310L2-5D

Instructions for Installing the Module

To install the Total Access 3000/3010 T1-OR/NIU, perform the following steps:

1. Set the Span Power option to either T1-OR or NIU. Two board-mounted jumper straps (P4)

select this span power option.

a. Set Span Power option to T1-OR. Move P4 straps to posts 1-3 and 2-4 (default setting).

With the straps positioned in the 1-3 and 2-4 configuration (factory default setting),

span power is software controlled.

b. Set Span Power option to NIU. Move the straps to the 3-5 and 4-6 position.

In positions 3-5 and 4-6, span power is always disabled and software selection is

ignored regardless of screen indication.

CAUTION

If the card is provisioned as a T1-NIU, change jumper P4 to 4-6 and

3-5. Failure to change the strap prevents the span power from

looping back properly through the unit, and the line powered

devices do not receive power.

2. If present, remove the Access Module Blank (P/N 1191953L1) from the appropriate access

module slot of the Total Access 3000/3010 chassis.

3. Pull the ejector latch, located on the lower left-hand side of the T1-OR/NIU front panel,

from its closed position.

4. Hold the T1-OR/NIU by the front panel while supporting the bottom edge of the module

with the ejector latch opened to engage the chassis edge.

5. Align the module edges to fit in the lower and upper guide grooves for the access module

slot.

6. Slide the module into the access module slot. Apply simultaneous thumb pressure at the

top (above the

PWR LED) and at the bottom (below the electrostatic caution symbol) of the

module. This ensures that the module is firmly seated against the backplane of the

chassis.

7. Secure the T1-OR/NIU in place by pushing in on the ejector latch.

Once properly installed, the T1-OR/NIU performs a series of self-tests. Once the self-tests are

complete, the front panel LEDs indicate the true status of the hardware.
