n Step Action
1 To gain access to the LAN Connectors, open the LAN Cable Access Door, then pull apart the
fabric covering the BNC “T” Connector and slide out the Service Tray, if desired.
– Refer to Figure 3-3.
2 Connect the LMF Computer to the LAN A (left–hand) BNC Connector by using a PCMCIA
Ethernet Adapter.
NOTE
Xircom Model PE3–10B2 or equivalent can also be used to interface the LMF Ethernet
Connection to the BTS 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 the Chassis Ground. The LAN Shield (exposed portion of the
BNC Connector) must not touch the chassis during Optimization.
