1. If the IOTA is installed on a carrier in a cabinet, rotate the rotary
button to unlock the NAMholding the NAM to the IOTA and
remove the module from the IOTA so power is removed from the

the long gray plastic screw located on the module's face.)
2. Carefully align the pins in the bottom of the NAM with the sockets
in the connector on the IOTA and gently push down on the module
until it is fully seated.
3. Rotate the rotary button clockwise in the base of the module to
secure it to the IOTA .
4. Connect appropriate fiber optic cable to the plug provided with
the fiber optic module.
