ATTENTION: Do not force and I/O module into a backplane
connector. Forcing an I/O module can damage the backplane
connector or the I/O module.
Calculate the total current requirement for all installed modules to ensure
that the sum does not exceed the limit of the I/O chassis’ power supply.
The 1772-LWP, -LXP, and -LZP processor provides 4A to power the I/O
modules. If you need additional power, you can choose either a 1771-P3
or 177-P4 power supply module to parallel to the 1772-LWP, -LXP, -LZP:
