PCB INSTALLATION

Handling the PCBs

The PCBs are sensitive to static discharge. To minimize static discharge, keep PCBs in static free bags when
not installed. Observe the following when installing or removing a PCB:
● Ground the cabinet.
● Wear a grounded wrist strap to install/remove any PCBs.
● Do not touch PCB components. Handle the PCBs in the corners.
● All PCBs must be installed with the system power off.

Installing an Extension or Trunk PCB (Figure 2-2)

To install an extension/trunk PCB:

● Power down the system.
● Push the retaining bar up (or back depending on the cabinet's position).
2-2 ◆ Section 2: PCB Installation and Startup
Whenever powering down the system, check to make sure the only LED flashing on the CPU
card itself is the LD2 LED (farthest right of the LEDs). This LED is located in the lower left-hand
corner of the CPU. If any other LEDS are flashing on the CPU, wait until they stop or else the sys-
tem data may be corrupted.
