Cabletron Systems manual POWER-UP and Boot Procedures, Normal Mode CSMIM-T1 Diagnostics

Chapter 5: Troubleshooting Procedures

During power-up and booting, it is more difficult to diagnose problems because they can originate in the CSMIM-T1, the network, or the load server host. However, the LEDs provide both a progress report and an error display to assist you in troubleshooting.

NOTE

If an error occurs, save the status of these LEDs. Technical support personnel can use this information to diagnose problems.

5.2POWER-UP AND BOOT PROCEDURES

The CSMIM-T1 has two modes of operation: normal and set up. Normal mode is the standard operational mode. SET UP mode provides access to the ROM Monitor commands. Pressing the SET UP button on the front panel puts the CSMIM-T1 into SET UP mode. When the CSMIM-T1 is in SET UP mode, the SET UP LED lights.

During the CSMIM-T1 power-up and boot sequence, the CSMIM-T1 runs a set of diagnostics. The system LEDs display the diagnostics’ status. The CSMIM-T1 stops when it detects one of two error conditions (see Table 5-2). The pattern of the system LEDs identifies the error condition.

5.2.1Normal Mode CSMIM-T1 Diagnostics

Following power-up or reset, the CSMIM-T1 enters normal mode. The following subsections describe both the possible error and error-free conditions that can occur during power-up and booting in normal mode.
