Pinging the Processors
Pinging the BTS
For proper operation, the integrity of the Ethernet LAN A and B links
must be verified. Figure 3-9 represents a typical BTS Ethernet
configuration for an SC4812T Lite stand–alone or companion frame.
The drawing depicts cabling and termination for both the A and B
LANs.
Ping is a program that sends request data packets to hosts on a network,
in this case GLI modules on the BTS LAN, to obtain a response from the
“target” host specified by an IP address.
Follow the steps in Table 3-11 to ping each processor (on both LAN A
and LAN B) and verify LAN redundancy is working properly.
CAUTION
Always wear an approved anti–static wrist strap while handling
any circuit card/module to prevent damage by Electro–Static
Discharge (ESD).
