7-6 Installing replaceable parts
Electrostatic
discharge (ESD)
precautions
Failure to follow these
precautions may damage
the electrostatic-sensitive
components.
Electronic components are sensitive to elec
trostatic discharge. Before working with the
modules in the terminal, put on your ESD
wrist strap and connect it to the ESD connec
tion points shown in Figure 7-2.
Before replacing any component, disconnect
the supplementary power supply.
When removing any component with a PCP,
put it in an anti-static bag or on an anti-static
surface to work with it.
Do not get any components wet.
1.
Remove the handset from its cradle and let it hang by
the armored cord.
2. Grasp the front housing assembly firmly by both sides
and tip it forward until the housing clears the rear of the
terminal.
3. Hold the front housing and move it downwards to the
open position, as shown in Figure 7-2.
In the fully open position, the weight of the front housing
is supported by the link assembly tie rods attached to
the front and rear housing, also indicated in Figure 7-2.
4. Attach your ESD wrist strap to an ESD connection
point, which is indicated in Figure 7-2.
5.
Disconnect the power to the terminal in one of the fol
lowing ways:
• Disconnect the rear terminal PCP cable (J18) from
the control PCP connector (J5). Refer to Figure 7-
2
.
• If you will be working with the rear terminal PCP,
disconnect the upper terminal block, shown in Fig
ure 7-3, which attaches at the rear terminal PCP.
