2.1 Initial Installation
This installation procedure applies to the first time an IBBC shelf will be populated with
a RTAU module. If the IBBC shelf has already been populated with a RTAU module, go
to 2.2. Maintenance Installation (Existing System).
Installation consists of unpacking and installing the RTAU module, and verifying that it is
functioning properly. Use the following procedure to install a RTAU module:
Caution: Electronic modules can be damaged by static electrical discharge. Before handling
modules, wear an anti-static discharge wrist strap to prevent damage to electronic
components. Place modules in anti-static packing material when transporting or storing. When
working on modules, always place them on an approved anti-static mat that is electrically
grounded.
Warning: If the RTAU module is improperly installed, damage can be caused to the system.
Be careful when inserting the RTAU module into a new chassis.
Caution must be used to prevent bending pins when inserting modules into a new IBBC shelf.
Once a module has been successfully seated in the connector, it “trains” the pins and aligns
them to the modules connector greatly reducing the chances of bending pins on subsequent
insertions. The following procedure outlines a method to mitigate the risk on a new shelf
installation.
1. Open the front cover of the Soneplex Broadband system.
2. Open the shipping carton and carefully unpack the RTAU module from its protective
packing material.
3. Once the Soneplex shelf has been installed and powered up:
a. Remove both-48V A and B side fuses (and “pilot” fuses if used).
b. Inspect the RTAU slots for bent or misaligned pins.
c. If pins are not bent, continue to the next step. If pins are bent, refer to 2.1.1 Damaged
Pins section.
4. With shelf unpowered, refer to the chassis marking above the module slot (Figure 2) to
install the RTAU module in the full-height slot labeled TAU.
