3. At the command prompt, type ping nnn.nn.nn.nn (the external IP trunk server’s
address), and press Enter.
If configured correctly, the system displays:
Reply from nnn.nn.nn.nn: bytes=32 time<##ms TTL=###
If there is no reply, verify the IP address and check the physical connections to and from the
TN802 circuit pack.
4. At the command prompt, type ping nnn.nn.nn.nn (the IP address of another computer
on the network), and press Enter.
If configured correctly, the system displays:
Reply from nnn.nn.nn.nn: bytes=32 time<##ms TTL=###
If there is no reply:
a. Verify the IP address.
b. Check the physical connections to and from the TN802 circuit pack.
c. Check the internal cables on the TN802 circuit pack (Notes 4 and 6 in Figure 87: TN802
board assembly and cables (side view) on page 1520).
d. Try pinging another device in the same subnet.
e. Try pinging the gateway to the rest of the network from the subnet.
f. Try pinging a device outside the local subnet but inside the network or another subnet.
5. When finished, type exit at the command prompt, and press Enter.
Internal Connections to the LAN
Test the internal connections to the LAN by pinging the local host, an internal IP trunk server,
and another device connected to the network.
1. Click Start in Windows (lower left-hand corner), then select Programs, then Command
Prompt.
This starts a DOS command-line session.
2. At the command prompt, type ping 127.0.0.1 (the local host’s default address), and
press Enter.
If configured correctly, the system displays:
Reply from nnn.nn.nn.nn: bytes=32 time <##ms TTL=###
If there is no reply:
a. Check that the internal cables on the TN802 circuit pack (Notes 4 and 6 in
Figure 87: TN802 board assembly and cables (side view)
on page 1520 have not
worked loose.
b. Otherwise, replace the circuit pack.
