LMF to BTS Connection
Connect the LMF to the BTS
The LMF computer may be connected to the LAN A or B connector
located behind the frame lower air intake grill. Figure 3-6 below shows
the general location of these connectors. LAN A is considered the
primary LAN.
Table 3-10: Connecting 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 3-6). If desired, slide
out the utility shelf for the LMF computer.
2
Connect the 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 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.
