Cabletron Systems CSX1000, CSX1200 manual Verifying WAN Lines are Available for USE

USER’S GUIDE

VERIFYING WAN LINES ARE AVAILABLE FOR USE

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 System Commands chapter.

2.You may also determine if WAN lines are operational by viewing the system messages: at the administration console type:

dr <return>

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: <slot #> <port #> <ces>

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 WAN Line Availability in the Problem Diagnosis chapter.

VERIFYING LAN CONNECTION IS OPERATIONAL

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.
