Installing or Removing the Module While Power Is Applied
You can install or remove the module while chassis power is
applied.
Install the Serial Adapter Cables
Three identical serial adapter cables are supplied. Each cable has a
locking-type
RJ45
plug on one end and a DB-9 male connector on
the other end. Insert the
RJ45
connector on each cable into the
RJ45
receptacles marked PRT1, PRT2, and PRT3 on the module.
When you insert or remove a module
while
backplane power is on, an electrical arc may occur.
An electrical arc can cause personal injury or
property damage by:
• sending an erroneous signal to your system’s
actuators causing unintended machine motion or
loss of process control.
• causing an explosion in a hazardous
environment.
Repeated electrical arcing causes excessive wear to
contacts on both the module and its mating
connector. Worn contacts may create electrical
resistance that can affect module operation.
To install the locking-type
RJ45
connector, slide the plug into
the receptacle. The locking
mechanism prevents the cable
from being removed during
normal operation. To remove
the cable, press the locking tab
and remove the plug.
