TROUBLESHOOTING PROCEDURES
4.1
GENERAL
The CSMIM2's front panel displays 4 system indicators and 16 or 32
status indicators. The system indicators are labeled Stat, Traf, Attn, and
S/U. The status indicators are numbered 1 through 32. The MODMIM
and the MODEXT cards display 5 LED indicators, CTS, DTR, TXD,
RXD, DCD, per modem port.
The system indicators provide information about normal operations and
about problems that occur. Use these indicators and the ROM Monitor
commands to diagnose problems.
The status indicators display port activity during normal operations; each
indicator supports 1 port.
During power-up and booting, it is more complicated to diagnose
problems because they can originate in the CSMIM2 or the load server
host. However, the indicators provide both a progress report and an error
display to assist you in troubleshooting.
4.2
POWER-UP AND BOOT PROCEDURES
The CSMIM2 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 switch on the front
panel, within 30 seconds of powering–up, puts the CSMIM2 into Set Up
mode. When the CSMIM2 is in Set Up mode, the S/U indicator lights.
Figure 1-3 in Chapter 1 illustrates the CSMIM2's front panel.
During the power-up and boot sequence, the CSMIM2 performs a set of
diagnostics. The system indicators display the diagnostics' status. The
CSMIM2 stops when it detects one of two error conditions (see Table
4-2). The pattern of the system indicators identifies the error condition.
