Installation
Before installing your EPC-6A, you should unpack and inspect it for shipping damage.
Avoid causing ESD damage:
• Remove modules from their antistatic bags only in a static-free environment.
• Perform the installation process (described later in this chapter) only in a
EPC-6A modules, like most other electronic devices, are susceptible to ESD
damage. ESD damage can cause a partial breakdown in semiconductor devices
that might not immediately result in a failure.

Determine whether to use the EPC-6A as a system controller

Before installing the EPC-6A in a VMEbus chassis, you need to decide whether the EPC-
6A will be the VMEbus Slot 1 System controller. Every VMEbus system needs a module
that performs the system controller functions, including generation of the 16 MHz
SYSCLK signal, arbitration of the bus, detection of Bus time-out conditions, and initiation
of the interrupt-acknowledge daisy chain. The EPC-6A can serve as the system controller.
To use the EPC-6A as the system controller:
• Make sure the jumper labelled SLOT1 is installed on the EPC-6A processor board to
connect the two pins. For information about jumper locations, see Figure 2-1, Jumper
locations on page 6.
• Install the EPC-6A in the leftmost slot on the chassis.
If you do not plan to use the EPC-6A as the system controller:
• Make sure the jumper labelled SLOT1 on the EPC-6A processor board is removed.
• Install EPC-6A in a slot other than slot 1 in the chassis.
Other jumpers and headers on the board are shown in the next table.
