Cabletron Systems CSX1000, CSX1200 manual Problem Diagnosis, LAN Adapter, General Procedures

PROBLEM DIAGNOSIS

OVERVIEW

This chapter, when used in conjunction with the System Verification chapter, helps diagnose and correct problems encountered in the verification process.

During some of the diagnosis procedures, we ask you to enter an administration console command. To enter these commands, you must have an active administration session. If you need instructions for starting an administration session, refer to Accessing the CyberSWITCH.

GENERAL PROCEDURES

For the following sections, note the following:

When you are given directions to “check configuration,” you may do so using CFGEDIT or Manage Mode. For details on these tools, refer to the Configuration Tools chapter.

In this chapter, if you are able to check or change information dynamically (i.e., while in Manage Mode), we will specify this. Remember, to enter Manage Mode, issue the manage command at the system prompt. Otherwise, assume that you will need to use the system’s configuration editor. To use CFGEDIT, enter the cfgedit command at the system prompt. Although this utility allows you to make changes to the configuration while the CyberSWITCH Software is still running, these changes do not take effect until the system is rebooted.

After making an configuration changes (and rebooting if necessary), return to the system software. The system prompt “System Name >” indicates that the system is up and running. Continue with the verification process using the dr command.

LAN ADAPTER

Problem:

The system does not display the LAN Adapter Initialization messages. Instead, the system displays one of the following messages:

Invalid LAN	Adapter	identifier
LAN Adapter	Command	Timeout
LAN Adapter	FIFO not	empty, status = #
LAN Adapter	LAN Controller error
LAN Adapter	Response	Timeout
Error opening file \system\io.bin
MAC layer Bridge did		not Initialize
[IP] Initialization		failure

Action:

1.Note the displayed error message. Restart the CyberSWITCH, and recheck for one of the above error messages.

2.If the error message is still displayed, contact your distributor for hardware replacement.
