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:

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

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

• CPU temperature alarm—If the temperature of the system CPU crosses the predefined threshold level,

• Fan alarm—The router has a fixed built-in fan for system cooling which runs at a variable speed. The

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.

• One or more hardware components on the router has failed.

• One or more hardware components on the router has exceeded the temperature threshold.

in router operation or degradation in router performance. A yellow alarm condition requires further

monitoring and/or maintenance.

the system triggers an alarm.

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.
