Connect the LMF to the BTS
The LMF is connected to the LAN A or B connector located on the left
side of the frame’s lower air intake grill, behind the LAN Cable Access
door (see Figure 3-3).
Table 3-5: LMF to BTS Connection
Step Action
1 To gain access to the connectors on the BTS, open the LAN Cable Access door, then pull apart the
Velcro® tape covering the BNC “T” connector (see Figure 3-3).
2 Connect the LMF to the LAN A BNC connector via PCMCIA Ethernet Adapter with an unshielded
twisted–pair (UTP) Adapter and 10BaseT/10Base2 converter (powered by an external AC/DC
transformer).
3 Start the LMF application (see Table 3-6 or Table 3-7) and test the connection.
– If there is no login response, connect the LMF to the LAN B connector.
– If there is still no login response, see Table 6-1, Login Failure Troubleshooting Procedures.
NOTE
– Xircom Model PE3–10B2 or equivalent can also be used to interface the LMF Ethernet
connection to the frame connected to the PC parallel port, powered by an external AC/DC
transformer. In this case, the BNC cable must not exceed 91 cm (3 ft) in length.
– The LAN shield is isolated from chassis ground. The LAN shield (exposed portion of BNC
connector) must not touch the chassis during optimization.
