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.

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.

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.

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