Figure 40: Installing the IOM
e. When the IOM is lowered fully, apply light pressure with both hands evenly on the IOM
body, not the handles, to seat the IOM in the connector. If the IOM won't seat correctly,
DO NOT FORCE IT. Instead, back the IOM out, check the pins to make sure none are
damaged, and try again.
f. Once the IOM is seated properly in the slot, close the handles until they latch closed.
6. Push the chassis back into the rack. Verify that the fan have slowed to their regular RPM. This
ensures that the enclosure is back to its proper cooling settings.
7. Check the fault LEDs on the IOM or on the enclosure's front and rear LED panels to determine
if there is a firmware mismatch between the replacement IOM and the IOM that was not
replaced.
a. If the fault LED is illuminated, open a command prompt on the host server issue the
following command using SG3_utils.
