CPU PCB Replacement
The CPU PCB is the first PCB located toward the front of the card cage as shown in
Figure 2-19. Refer to the following procedure for replacing the CPU PCB.
1. Turn OFF the power switch to the EMT 10/4T.
2. Remove the card cage cover and install a static grounding strap between the
working surface and the personnel performing this procedure.
3. Grasp the CPU at the corners and gently rock it out of its connectors in the
backplane PCB. Remove the CPU.
CAUTION! It is advised to place the removed PCB into an anti-static
bag before handling it any further. Portions of this board are very
sensitive to static charges.
4. To replace the CPU PCB, perform the previous steps in reverse order.
5. Remove the static grounding strap and replace the card cage cover.
NOTE: If during this procedure, the CPU has been replaced with a different one,
you must "configure" the embroidery peripheral. Refer to the peripheral
operation manual and Section 1 of this manual for information regarding
the configuration process.
Ethernet Network PCB
The Ethernet PCB is positioned inside the card cage of the peripheral between the
CPU PCB and the Interface PCB as Figure 2-19 shows. Refer to the following
procedure for replacement.
1. Turn OFF the power switch to the EMT 10/4T.
2. Remove the card cage cover and install a static grounding strap between the
working surface and the personnel performing this procedure.
3. Disconnect the Ethernet cable from the bottom end of the PCB at the Ethernet
card edge mounting bracket.
4. Remove the screw and washer at the card edge mounting bracket for the PCB.
5. Grasp the Ethernet PCB at the corners and gently rock it out of its connectors in
the backplane PCB. Remove the Ethernet PCB.
CAUTION! It is advised to place the removed PCB into an anti-static
bag before handling it any further. Portions of this board are very
sensitive to static charges.
