Did you already update the firmware of the series E modules?
• Yes — Go to step 6.
• No — Continue with step 5.
A. Remove the 1757-SRM module from the secondary chassis.
B. Set the address of each series E module to the address of its corresponding series D
module plus one.
C. Replace each series D module with the corresponding series E module.
Important: Make sure you connect the correct ControlNet tap to each module.
D. Use ControlFlash software and update the firmware of each series E module.
E. Remove the series E modules from the secondary chassis and set their addresses to
match the original series D modules.
F. Repeat steps B-E for the second set of series E modules.
G. Put the secondary SRM back into the secondary chassis.
H. Put one set of series E modules into the secondary chassis.
Important: Make sure that you use the correct address, slot, and ControlNet tap for
each module.
I. Go to step 7.
Replace the CNB/D modules in the secondary chassis with series E modules. As you
replace the modules:
• make sure that you set each module to the same address as the module that it is
replacing.
• make sure that you connect the correct ControlNet tap. To avoid connecting the wrong
tap, replace the modules one at a time and reconnect the ControlNet tap.
