Figure 11-1 shows the CTC node view Alarms window.

Alarms and conditions appear in one of five background colors, listed in Table 11-2, to communicate
severity.
Note
Major and Minor alarms may appear yellow in CTC under certain circumstances. This is not due to a
CTC problem but to a workstation memory and color utilization problem. For example, a workstation
might run out of colors if many color-intensive applications are running. When using Netscape, you can
limit the number of colors used by launching it from the command line with either the -install option or
the -ncols 32 option.
