Publication 1734-IN041B-EN-P - October 2013
If you set the switches to an invalid number (for example, 000 or a value greater than 254
excluding 888), the adapter checks to see if you enabled DHCP.
Replace The Adapter
Use these procedures to install a replacement adapter to an existing system.
1. Disconnect the Ethernet connector(s) from the adapter.
2. Pull up on the Removable Terminal Block (RTB) handle to remove the terminal
block.
DHCP Enabled and Not Enabled
DHCP State Adapter Action
Enabled Asks for an address from a DHCP server. The DHCP server also assigns other
Transport Control Protocol (TCP) parameters.
Not enabled Uses the IP address (along with other TCP configurable parameters) stored in
nonvolatile memory.
WARNING: When you change switch settings while power is on, an electrical
arc can occur. This could cause an explosion in hazardous location
installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
WARNING: When you insert or remove the module while backplane power is
on, an electrical arc can occur. This could cause an explosion in hazardous
location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
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.
WARNING: When you connect or disconnect the Removable Terminal Block
(RTB) with field side power applied, an electrical arc can occur. This could
cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
