Card Cage Components
Inside the card cage is found the Backplane PCB lying against the end of the chassis
leg with its respective PCBs inserted into its connectors. The PCBs installed are:
• The CPU PCB
• The Ethernet network PCB
• The Interface PCB
• Blank space
• The LV Driver PCB
Refer to Figure 2-19 for identifying where each PCB is specifically located.
CAUTION! In removing any PCBs from the EMT 10/4T, use extreme
care in handling. Portions of the boards are very sensitive to static
charges and handling them must be done using a static grounding
strap as instructed in specific procedures in this manual.
