5.1.2. Installing a New Unit

Use the following steps to install the T1-S.

Step Action

1. If not already installed, install the rear panel, screwing it to the appropriate mounting locations on the

shelf using the provided hardware.

WARNING

Due to mechanical differences the T1-S card can only be installed in Issue 3 or greater ICB

shelves. If there is already a rear panel installed on the shelf, check for interference when

installing. The rear panel may need to be removed and replaced with the rear panel that has

been shipped with the new unit.

2. Insert the unit into the shelf, making sure that the unit is aligned with the card guides inside the shelf.

3. Slide the unit fully into the shelf. Use the insertion lever to fully seat the unit.

4. Once the unit is fully inserted, tighten the securing screw on the front panel of the unit.

5. Wire the unit per the wiring information in the wiring section. When power is applied, the unit will per-

form a self-test.

6. After the self-test is performed, check the software provisioning of the card using the front panel craft

interface on the front of the controller unit.

5.1.3. Installing a Replacement Unit

If you are replacing a unit that is already in service, insure that the new unit is the same as the unit being re-

placed.

Step Action

1. Remove the wiring connectors from the front and rear of the unit (J1 & J2 if applicable).

2. Unscrew the front panel securing screw to release the unit from the shelf.

3. Using the card ejector, remove the unit from the shelf.

4. Follow the procedure for installing a new unit.

5.2 Wiring the Unit

Use the following steps to wire the unit.

Step Action

1. Connect T1 to the rear panel RJ48 jack (J1).

2. If using the Ethernet interface, connect the Ethernet to J2 at the rear of the unit.

3. Set composite clock termination for your system as described under Hardware Optioning, page 12.

4. If you are using composite clock, remove the connector and wire the signal to the connector CCLK IN.

5. Reinstall the connector with the composite clock signal wires.

6. Power and alarm should already be wired. If not, see the documentation for the ICB shelf.

5.3 Front Panel Switch and LED Definitions

The Audible Alarm Cut Off (ACO) switch is a pushbutton used to open the audible alarm contacts from the

360-80 system. This switch will only mask audible indications of present alarm conditions—it does NOT clear the

alarm. If a new alarm occurs, the audible indication will re-enable.

The Address ID switch on the front panel is a multi-section switch for setting the system address on the system

management bus. This switch is used if the system is connected together with other 360-80 systems into a man-

agement control center. This switch allows the control center to ‘address’ the individual systems. See section on

network management for more information.
