Maintenance and Troubleshooting
You can monitor and troubleshoot the vEdge 100m router using the various LEDs and system alarms on the
router.
Alarm Severity Levels
The system alarms on the vEdge 100m router have two severity levels:
• Major (red)—Indicates a critical situation on the router resulting from one of two conditions:
• One or more hardware components on the router has failed.
• One or more hardware components on the router has exceeded the temperature threshold.
A major alarm condition requires immediate attention. If a temperature related major alarm persists for more
than five minutes, the router will shut down.
• Minor (yellow)—Indicates a warning on the router that, if left unattended, might result in an interruption
in router operation or degradation in router performance. A yellow alarm condition requires further
monitoring and/or maintenance.
Hardware Alarms
Hardware alarms on the vEdge 100m router are predefined and are triggered by a physical condition on the
router such as a power supply failure, excessive component temperature, or fan failure. The vEdge 100m
router triggers the following types of hardware alarms:
• Main board temperature alarm—The main board of the router has one temperature sensing point (board
sensor 0). If the temperature of the sensor location crosses the predefined threshold level, the system
triggers an alarm.
• CPU temperature alarm—If the temperature of the system CPU crosses the predefined threshold level,
the system triggers an alarm.
• Fan alarm—The router has a fixed built-in fan for system cooling which runs at a variable speed. The
Viptela software maintains the fan at an optimal fan speed, raising the speed as the ambient temperature
increases and decreasing the speed as the temperature decreases, to keep the router operating at the lowest
possible temperature in the green temperature threshold. If the fan stops running, the system triggers an
alarm. Also if the fan starts to run below a predefined RPM threshold, the system triggers an alarm.
Table 1 lists the yellow and red alarm threshold for the temperature sensing points in the system—one board
sensor on the board and one CPU junction temperature sensor. The lower threshold value (Bad Fan) applies
if a fan failure condition is also detected; otherwise, the higher threshold value (normal) applies.
