Switching the Active LAN
When the LMF Computer is connected to the BTS at the I/O Panel
10Base–2 LAN Connectors, switching the INS_ACT GLI Card to
another LAN (Active LAN Swap) requires more operator actions than
with a Service Shelf LMF Connection. Follow the procedure in
Table 3-8 to force the active LAN Swap with this type of connection.
This procedure is written so it can be used starting with
either LAN A or LAN B.
NOTE
Table 3-8: Forcing an Active 10Base–2 LAN Swap with LMF I/O Panel Connection
n Step Action
1 With the LMF Computer connected to a 10Base–2 LAN at the I/O Panel, force the INS_ACT GLI
Card to swap to the other 10Base–2 LAN by performing the following actions.
– Refer to Figure 3-4.
1a Disconnect the LMF COAXial Cable from the I/O Panel LAN OUT Connector.
1b Remove the 50Ω Terminator from the BNC “T” Connector at the 10Base–T/10Base–2 Converter
or Hub (Figure 3-4).
1c Install the 50Ω Terminator on the I/O Panel LAN OUT Oonnector from where the COAXial
Cable was removed in Step 1a, above.
1d Wait approximately 15 seconds.
1e Remove the 50Ω Terminator from the other I/O Panel LAN OUT Connector, and install it on the
open jack of the BNC “T” Connector at the 10Base–T/10Base–2 Converter or Hub (Figure 3-4).
1f Connect the COAXial Cable to the LAN OUT Connector from which the 50Ω Terminator was
removed in Step 1e, above.
1g Wait approximately 15 seconds.
2 If applicable, return to the procedure that required performing this operation.
3 If not directed to this operation from another procedure, briefly remove and then replace the 50Ω
Terminator on the I/O Panel LAN IN Connector for the LAN from which the LMF was
disconnected in Step 1a, above.
4 Verify the LAN is active by pinging the processor of the INS_ACT GLI Card using the procedure
in Table 3-15.
