Pinging the BTS
For proper operation, the integrity of the Ethernet LAN A and B links
must be be verified. NO TAG 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.
Follow the steps in Table 3-12 to ping each processor (on both LAN A
and LAN B) and verify LAN redundancy is working properly.
Always wear a conductive, high impedance wrist strap
while handling any circuit card/module to prevent damage
by ESD.
