Determining Hardware Status

SmartEdge 400 Router Hardware Guide
Table 5-3 lists the LEDs that indicate system-level alarm status.
Determine Card Status with LEDs
Each SmartEdge 400 controller and traffic card has equipment (card) and facility (port) LEDs to indicate
current status of the card and its ports. Additionally, the controller cards have synchronization LEDs to
indicate the status of any externally configured timing sources.
The card LEDs are described in the following sections:
• Ethernet and Gigabit Ethernet Cards
For information about configuring cards and using the operating system software to troubleshoot errors, see
the
Basic System Configuration Guide
for the SmartEdge OS.
