To verify the availability of WAN lines, the WAN resource must already be operational. Also, the
WAN lines must already be configured and connected to the CyberSWITCH.
To verify the availability of WAN lines:
1.
Check the Line SYNC LED for each line. If the operational software determines that Layer One
is up, then this indicator light is on.
If you are not where you can see the system’s LED display, use the
status
command via
Telnet to verify the availability of WAN lines. Instructions for using this command are
provided in the
chapter.
2.
You may also determine if WAN lines are operational by viewing the system messages: at the
administration console type:
dr
The
dr
command displays the current system messages.
3.
For each basic rate or primary rate line configured and attached to the CyberSWITCH, the
following line initialization message should be displayed among the system messages:
Data Link up:
Depending on the resource switch type, the system will delay up to 2 minutes before
attempting to bring up the data links.
Note:
Other messages may also be displayed with the line initialization messages.
If this message is displayed for each configured line, then the WAN lines are available for use.
If the line initialization message for a configured line is NOT displayed, refer to
in the Problem Diagnosis chapter.

To verify the operation of the LAN connection, the Ethernet LAN adapter resource must already
be operational.
To verify the operation of the LAN connection:
1.
Connect the CyberSWITCH to as properly terminated Ethernet LAN. If an external MAU is
used, AUI cabling must be used. 10Base-T can also be used (with no MAU). If both types of
connections are used, the 10Base-T will be the overriding connection.
2.
If 10Base-T is used, check the 10Base-T LED on the CyberSWITCH. If this connection is
working properly, the 10Base-T LED light will shine steadily.
3.
If a MAU with AUI cabling is used, check the MAU’s LED.
