Pinging the Processors

PRELIMINARY
Pinging the BTS
For proper operation, the integrity of the 10Base–2 Ethernet LAN A and
B Links must be verified. Figure 3-10 represents a typical BTS Ethernet
Configuration for an SC4812T Lite Stand–alone Frame. The drawing
depicts cabling and terminators 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 Cards on the BTS LAN, to obtain a response
from the “Target” Host specified by an IP Address.
Perform the steps in Table 3-15 to ping each processor (on both LAN A
and LAN B) and verify that LAN Redundancy is working properly.
Always wear an approved Anti–static Wrist Strap while
handling any circuit card/module to prevent damage by
Electrostatic Discharge (ESD).
