PRELIMINARY
The Ethernet LAN A and B cables and/or terminations
must be installed on each frame/enclosure external LAN
connector before performing this test. All other processor
board LAN connections are made through the backplanes.

Table 3-12: Pinging the Processors
Step Action
1 If this is a first–time communication with a newly–installed frame or a GLI2 which has been replaced,
perform the procedure in Table 6-3 and then return to step 2.
2 Be sure uncabled LAN A and B IN and OUT connectors in the power entry compartment (rear of
frame – Figure 3-9 and Figure 3-12) are terminated with 50 Ω loads.
3 If it has not already been done, interface the LMF computer to the BTS (refer to Table 3-6 and
Figure 3-10.)
4 If it has not already been done, start a GUI LMF session and log into the BTS ( refer to Table 3-7).
5 In the power entry compartment, remove the 50Ω termination on the frame LAN B IN connector. The
CDMA LMF session should remain active. Replace the 50
Ω terminator on the BTS frame LAN B IN
connector.
6 From the Windows desktop, click the Start button and select Run.
7 In the Open box, type ping and the GLI2 IP address (for example, ping 128.0.0.2).
NOTE
128.0.0.2 is the default IP address for the GLI2 in field BTS units.
8 Click on OK.
9 If the targeted module responds, a DOS window will appear with a display similar to the following:
Reply from 128.0.0.2: bytes=32 time=3ms TTL=255
S If the device responds, proceed to step 18.
If there is no response the following is displayed:
Request timed out
S If the GLI2 fails to respond, it should be reset and re–pinged. If it still fails to respond, typical
problems would be: failure of the CDMA LMF to login, shorted BNC to inter-frame cabling, open
cables, crossed A and B link cables, or the GLI2 itself.
10 Logout of the BTS as described in Table 3-9, exit from the CDMA LMF program, and restart the
Windows operating system on the CDMA LMF computer.
11 Restart the CDMA LMF GUI program as described in LMF Help function, and log into the BTS as
described in Table 3-7.
12 Perform steps 6 through 9 again.
S If the device responds, proceed to step 18.
If there is still no response,proceed to step 13.
