LMF to BTS Connection
The CDMA LMF computer may be connected to the LAN A or B
connector located behind the frame lower air intake grill. Figure 3-10
below shows the general location of these connectors. LAN A is
considered the primary LAN.
Table 3-6: Connect the LMF to the BTS
Step Action
1 To gain access to the LAN connectors, open the LAN cable and utility shelf access panel, then pull
apart the hook–and–loop fabric covering the BNC “T” connector (see Figure 3-10). If desired, slide
out the utility shelf for the LMF computer.
2
Connect the CDMA LMF computer to the LAN A (left–hand) BNC connector via PCMCIA Ethernet
Adapter.
NOTE
Xircom Model PE3–10B2 or equivalent can also be used to interface the CDMA 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 three feet 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.
