Step Action
15 After the BTS has been successfully pinged, be sure the 50Ω termination was replaced on the BTS
frame LAN B IN connector in the power entry compartment (Figure 3-9). Disconnect the LMF cable
from the LAN shelf LAN A connector, and connect it to LAN B (right–hand connector) (refer to
Figure 3-3).
16 In the power entry compartment, remove the 50Ω termination on the BTS frame LAN A IN connector.
17 Repeat steps 5 through 9 using LAN B.
18 After the BTS has been successfully pinged on the secondary LAN, replace the 50Ω termination on
the frame LAN A IN connector in the power entry compartment.
19 Disconnect the LMF cable from the LAN shelf LAN B and connect it to LAN A.
20 Remove and replace the 50Ω termination on the LAN B IN connector to force the MGLI to switch to
primary LAN A.
21 Repeat steps 5 through 9 to ensure proper primary LAN operation.
