Maintenance and Troubleshooting

Now that you have installed and connected the vEdge 5000 router, you can monitor and troubleshoot the various LEDs and system alarms on the router.

​Alarm Severity Levels

The system alarms on the vEdge 5000 router have two types of severity levels:

  • Critical (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 critical alarm condition requires immediate attention. If a temperature related major alarm persists for more than five minutes, the router will shut down.

  • Major (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 5000 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 5000 router triggers the following types of hardware alarms:

  • Main board temperature alarm—The main board of the router has four temperature sensing points (board sensor 1 through 4). If the temperature of the sensor location crosses the predefined threshold level, the system triggers an alarm.
  • CPU Junction temperature alarm—If the temperature of the system CPU crosses the predefined threshold level, the system triggers an alarm.
  • PIM temperature alarm—If the temperature of the PIM modules crosses the predefined threshold level, the system triggers an alarm.
  • Fan alarm—The router has modular fan trays for system cooling. The Viptela software maintains the fans 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 a fan stops running, the system triggers an alarm. Also if a fan starts to run below a predefined RPM threshold, the system triggers an alarm.
  • Power supply alarm—The router has two power supplies for redundancy reasons. If one of the power supplies is not plugged in or there is a failure on a power supply input, the system triggers an alarm

​Table 1 lists the yellow and red alarm threshold for the nine temperature sensing points in the system—four board sensors spread across the board, one CPU junction temperature sensor, and two PIM temperature sensors. The lower threshold value (Bad Fan) applies if a fan failure condition is also detected; otherwise the higher threshold value applies (normal).

Checking Alarms and Notifications

To view the current chassis environment condition , enter the show hardware environment command at the system prompt. The system displays the power supply status, temperature sensor readings, fan speed, and related alarm status if any exists.

To view the severity of active alarms, enter the show hardware alarms command at the system prompt. The system displays the alarm severity and a brief description of the cause of each active alarm.

To view temperature thresholds at which green, yellow, and red alarms are generated, enter the show hardware temperature-thresholds command at the system prompt. The system displays the alarm temperature threshold information for a mother board in the router and for the router's CPU.

To view all other events on a Viptela device, enter the show notification stream command. The system displays notifications about events that have occurred on the Viptela device.

LEDs and LCD Panel

The chassis LED located on the front panel of the vEdge 5000 router indicates the status of the router. See Front Panel Components for details of the LEDs and the status they indicate.

The LCD panel also displays information about the status and health of the router.
