1. Remove the power from the base in which you are installing the

PPX:505–6860.

WARNING

Installing or removing any module from a powered-up base could cause

unexpected operation which could cause death or serious injury to personnel,

and/or damage to equipment.

To prevent disruption of the I/O channel, disconnect the I/O channel cable

before removing or installing the PPX:505–6860.

2. In the case of a 545–1104, 555–1103, or 555–1104 installation, install

the PPX:505–6860 in the same base as the CPU, in the first double I/O

slot adjacent to the CPU.

In the case of a 575–2104 installation, the PPX:505–6860 must be

installed in a Series 505 base within three feet of the 575 base that is

electrically bonded to the Series 505 base.

CAUTION

The PPX:505–6860 is sensitive to, and can be damaged by, electrostatic

discharge.

Ensure that personnel make contact with a static-dissipative pad and/or wear a

grounded wrist strap when handling the PPX:505–6860.

backplane connector.
