When the Routing Engine detects an alarm condition, it lights the appropriate red or
yellow alarm LED on the HCM. The HCM is located on the front of the chassis below the
FPC card cage, as shown in Figure 1 on page 6.
The circular red alarm LED indicates a critical condition that can result in a system
shutdown. The triangular yellow alarm indicates a less severe condition that requires
monitoring or maintenance. Both alarms can occur simultaneously. For more information
about the alarm LEDs, see "M10i HCM Alarm LEDs" on page 23.
Chassis alarms—Indicate a problem with a chassis component such as the cooling
system or power supplies.
Interface alarms—Indicate a problem with a specific network interface, as described
in Table 16 on page 94.
In both tables, the text in the column labeled "CLI Message" appears in the output from
the

command.
