Mounting the Assembled Adapters on the I/O Base

Overview

This section gives guidelines, safety precautions and a procedure for mounting the

assembled Processor and Option Adapter on an I/O base.

Guidelines

The assembled adapters connect with the I/O base at these seven points:

Two plastic snaps on the front of the Option Adapter fit into two slots on the

front of the I/O base

The plastic snap extensions on the two sides of the Option Adapter fit into the

two slots on the sides of the I/O base

The 12-pin ATI connectors on the center of the back walls of the two units mate

together

The plastic stirrup on the back of the Option Adapter clips onto the bottom of

the I/O base

CAUTION

ELECTRICAL CIRCUITRY MAY BE EXPOSED

Electrical circuitry on the I/O base may be exposed when an adapter is not mounted. Make

sure that the I/O base is not under power whenever it does not have a Momentum adapter

mounted on it.

To make sure that power is not present, do not insert the wiring connectors to the I/O base

until after the adapter has been mounted. When more than one connector is on the I/O

base, remove all connectors to prevent the unit from receiving power from an unexpected

source.

Failure to observe this precaution can result in injury or equipment damage and will

void the product warranty.
