3.4 PCB INSTALLATION

PCB Handling & General Installation

All boards should not be installed or removed while power applied.

Power must be turned off prior to insertion or removal of the PCB.

The system PCBs contain digital circuitry which can be damaged by exposure to excessive static electricity. When

handling PCBs, a grounded wrist strap should be used to protect the boards from static discharges. Also, use common

sense when handling the PCBs. For example, do not place a PCB in locations where heavy objects might fall on the PCB

and damage components.

To insert a PCB, hold the PCB and, with component side facing right, insert the card into the MBU’s din connector firmly

and tighten. To remove a PCB, reverse the procedure. Installation method of PCB is shown in Figure 3.4.1.

Figure 3.4.1 PCB Installation

There are 6 slots in the GDK-20W system for extend or modify the system configuration. But, there are some restrictions

when optional board installation. Note that the system can not operate properly with wrong installation. The SLOT1 of the

MBU is reserved only for DVIB/DVIBE, the SLOT2 & SLOT3 is reserved for LCOBs or STIB2/STIB, the SLOT4 are

reserved only for PMU and the SLOT5 and SLOT6 is reserved for WTIB and MFB, respectively.

To summarize, see the following table 3.4.1.

Slot No. Cards Remark

SLOT1 DVIB, DVIBE Fixed slot for DVIB

SLOT2

SLOT3

LCOB2, LCOB, LCOBE,

LCOBA, LCOB4,STIB2, STIB Option board for LCO, ISDN

SLOT4 PMU Fixed slot for PMU(Basic)

SLOT5 WTIB Fixed slot for WTIB

SLOT6 MFB Fixed slot for MFB

[Table 3.4.1] Option Boards Installation Table

When the system power on, the default slot assignment is automatically redefined according to board installation status.

Main Board Unit (MBU) Installation

The MBU is installed in the KSU default. It comprised of main processor, four(4) Digital Terminal interface circuits, two(2)
