LMF to BTS Connection
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 3-4).
Table 3-6: LMF to BTS Connection
Step Action
1 To gain access to the connectors, open the LAN Cable Access door, then pull apart the Velcro tape
covering the BNC “T” connector and slide out the computer service tray, if desired (see Figure 3-4).
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). If there is no login response, connect the LMF to the LAN B BNC connector. If there is
still no login response, see Table 6-1, Login Failure Troubleshooting Procedure.
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.
* IMPORTANT
The LAN shield is isolated from chassis ground. The LAN shield (exposed portion of BNC connector)
must not touch the chassis during optimization.
