PCB Installation

Overview Instructions

The following is an overview for installing the Printed Circuit Boards (PCBs) into the Strata CTX28. After reading this section, proceed to the step-by-step instructions for each PCB.

1.Apply proper settings on the GMAU1A (motherboard Figure 1-7).

2.If applicable, set SW6 battery jumper to ON and install the GVMU1A Voice Mail card (Figures 1-8and 1-9).

3.Set P601 battery jumper to ON and install the GCTU1A (processor Figures 1-6and 1-10).

4.If applicable, install the GCDU1A (3 CO, 3 CLID and 8 DKT circuits Figure 1-11).

5.If applicable, install GSTU1A (standard telephone interface Figure 1-12).

6.If applicable, install the GETS1A 100Base-TX I/F PCB (Figure 1-13).

7.If applicable, install the BSIS1A for SMDR (Figure 1-6).

8.If applicable, install HPFB-6 battery/charger (Figure 1-14).

9.Connect wiring (Table 1-14).

10.Connect AC Adaptor to P2 of the CTX28 sub-motherboard (GMAS, Figures 1-15and 1-16) and plug the AC Adaptor into AC power.

11.Turn the System ON by sliding the SW1 ON/OFF switch down. The ON/OFF LED located by STANDBY will turn on (Figure 1-15).
