6.2 Hot Swapping An Ethernet Module
You ma
y
 replace 
y
our Ethernet web embedded server module while the controller 
is runnin
g
. However, 
y
ou should first make sure that the IP network address of the 
replacement module will be uni
q
ue on 
y
our network.
The new Ethernet module will inherit an
y
 confi
g
uration chan
g
es 
y
ou had made. If 
the ori
g
inal Ethernet module was 
g
iven a user-confi
g
ured address, the new module 
will assume that address. If 
y
ou will be usin
g
 the default address, check with 
y
our 
s
y
stem administrator to ensure that address is not alread
y
 in use on 
y
our network.
To hot swap the module, simpl
y
 disconnect the cable and remove the old module 
from the backplane. Then insert the new module in the slot and reconnect the 
cable.
If 
y
ou are replacin
g
 the module because it failed, be aware that 
y
ou ma
y
 have lost 
several transactions. These transactions are not captured in memor
y
 and cannot 
be recovered b
y
 the new module.
