1.
Mark all fibers that you plan to disconnect from the UFM4 and reconnect to the UFM3.
2.
If the UFM being replaced contains a BIC in BIC slot 2, and if you want to reuse that
BIC in the new UFM, follow the procedures in
“Removing a BIC” on page 126 to remove
the BIC from BIC slot 2.
3.
Follow the procedures in “Removing a UFM” on page 119 to remove the UFM4 you want
to replace.
4.
Wait a minimum of 60 seconds to allow time for the CMM to recognize that the UFM
has been removed.
5.
Follow the procedures in “Installing a UFM” on page 117 to install the UFM3.
6.
Follow the procedures in “Installing a BIC” on page 125 to install a 1x CFP BIC into BIC
slot 1, and to reinstall the BIC that you removed in 2 into BIC slot 2 of the UFM.

You have successfully completed this procedure.
UFM6 Installation Rules
Installation rules exist for the UFM6 when running on a BTI7814 powered with AC PEMs.
Table 43: Installation Rules
Power available for other modules
Maximum number of UFM6
modules
Input voltage to AC PEM
100 W 8 100 VAC
100 W 9 110 VAC
No restrictions are necessary. 180 VAC and above
The power available for other modules increases if you deploy fewer UFM6 modules
than the maximums specified in the scenarios above. This increase is equal to the power
saved for each UFM6 module allowed but not deployed. See
“BTI7800 Series Component
Power Consumption” on page 53 for the power consumption of the UFM6 and other
modules.
