MOUNTING STRUCTURE

The ZCP270 are installed in the 1x8 and 2x8

mounting structures. The two modules of a fault

tolerant ZCP270 must be mounted in adjacent

mounting structure slots to allow for installation of the

interconnecting fault-tolerant connector

LED INDICATORS

Light-emitting diodes (LEDs) on the front of the

ZCP270 module provide visual indication of the:

 ZCP270 operational status

 Communications activity of Ethernet control

network A and B links

 Communications activity of Ethernet fieldbus A

and B.

The control network path Tx LEDs indicate which

controller is primary as well as the network path it is

using; these LEDs are only active on the primary

module
