About Service Connections
A Series 494 Chassis can have several service connectors. There are two
types of connectors:
• The chassis connection monitors the power supply.
• The connection on the I/O carrier board monitors the output of each
card.
J3 I/O carrier service
connection
The J3 Service connector on the Model 494.40 I/O Carrier board provides
the monitor output from each of the four I/O option cards installed. It is an 8-
pin RJ-45 connector.
Important The signals at the J3 Service connector are provided for
service and troubleshooting only. These signals are defined by
the I/O option cards that are installed on a respective Model
494.40 I/O Carrier board. Some of these signals may be
uncalibrated. Before use, take appropriate steps to determine
the characteristics of these signals.
