Pinging the Processors
For proper operation, the integrity of the Ethernet LAN A and B links
must be be verified. Figure 3-5 represents a typical BTS Ethernet
configuration. The drawing depicts one (of two identical) links, A and B.
Ping is a program that sends request packets to the LAN network
modules to get a response from the specified target module.
NOTE
WinLMF (unreleased version 2.16.1.0.15 for example) has an
option in the LOGIN menu to ping the GLI prior to login.
Follow the steps in Table 3-7 to ping each processor (on both LAN A
and LAN B) and verify LAN redundancy is working properly.
CAUTION
Always wear a conductive, high impedance wrist strap while
handling any circuit card/module to prevent damage by ESD.

IMPORTANT: The Ethernet LAN A and B cables must be
installed on each frame/enclosure before performing this test. All
other processor board LAN connections are made via the
backplanes.
