Router Module Front Panel Components

42
The router module contains the following front panel items (as shown in Figure 2-7):
• L1 display. The L1 display is a 55.7 mm X 32 mm backlit liquid crystal display
(LCD) that displays system messages. It displays two lines with a maximum of 12
characters on each line.
• On/Off switch with LED. Press this button to turn on the router internal
components. You can also turn on the router internal components at a system
console.
• Three LEDs:
– Power-button LED. This green LED illuminates when the router internal
components are on and turns off when they are off.
– Service-required LED. This amber LED illuminates to indicate that an item is
broken or not operating properly (for example, a fan is off), but the router is still
operating.
– Failure LED. This red LED illuminates to indicate that a system failure has
occurred and the router is down.
• Fans. Two hot-pluggable fans provide N+1 redundant cooling.
