Hardware and Environmental Faults

This section describes the hardware and environmental faults. It includes information about fan speed, voltage, temperature, and power supply for the system.

Note:

If you suspect you have a hardware fault, contact Oracle Support for assistance with running the diagnostics image loaded on the Oracle Communications Session Border Controller.

Hardware Temperature Alarm

The following table describes the hardware temperature alarms.

Alarm Name Alarm ID Alarm Severity Cause(s) Example Log Message Actions Trap
TEMPERATURE HIGH 65538 CRITICAL: -100 MAJOR: -50 MINOR: -25 Fans are obstructed or stopped. The room is abnormally hot. Temperature: XX.XXC (where XX.XX is the temperature in degrees) 1. Check if fans or air vents that are obstructed 2. Check dust accumulation on vents or fans 3. Check Heating, Ventillation and Air Conditioning (HVAC) of the room. 4. Clean the filter apSysMgmtTempTrap
SD5_TEMPERATURE_HIGH_PHY0 NONE CRITICAL:>100°C MAJOR:>95°C MINOR:>90°C Fans are obstructed or stopped. The room is abnormally hot. Temperature: XX.XXC (where XX.XX is the temperature in degrees) Temperature X is at Y degrees C over minor/major/critical threshold of Z (Where X is sensor name, Y is temperature and Z is threshold) 1. Check if fans or air vents that are obstructed 2. Check dust accumulation on vents or fans 3. Check Heating, Ventillation and Air Conditioning (HVAC) of the room. 4. Clean the filter ap-env-monitor

Note:

If this alarm occurs, the system turns the fan speed up to the fastest possible speed.

Fan Speed Alarm

The following table describes the fan speed alarm.

Alarm Name Alarm ID Alarm Severity Cause(s) Example Log Message Actions Trap Generated
FAN STOPPED 65537 CRITICAL (-100): any fan speed is <50%. Or speed of two or more fans is >50% and <75%. MAJOR (-50): speed of two or more fans is > 75% and < 90%. Or speed of one fan is >50% and <75% and the other two fans are at normal speed. MINOR (-25): speed of one fan> 75% and <90%, the other two fans are at normal speed Fan speed failure. Fan speed: XXXX XXXX XXXX where xxxx xxxx xxxx is the Revolutions per Minute (RPM) of each fan on the fan module 1. Check if fans or air vents that are obstructed 2. Check dust accumulation on vents or fans. 3. Clean the filter apSysMgmtFanTrap

Note:

If this alarm occurs, the system turns the fan speed up to the fastest possible speed.

If the fan speed drops directly from functional RPM to 0 RPM, the SBC will generate a MINOR alarm and will decrement the health score by 25.

If the fan speed drops gradually to 0 RPM with intermediate RPM's involved, that is from a functional RPM to some lower RPM and then to 0 RPM, the SBC will generate a CRITICAL alarm and will decrement the health score by 100.

Environmental Sensor Alarm

The following table describes the environmental sensor alarm.

Alarm Name Alarm ID Alarm Severity Cause(s) Example Log Message Actions Health Score Impact
ENVIRONMENTAL SENSOR FAILURE 65539 CRITICAL (-10) The environmental sensor component cannot detect fan speed and temperature. Hardware monitor failure! Unable to monitor fan speed and temperature! Power cycle the standby Oracle Communications Session Border Controller peer using the power supply on/off switches located on the rear panel of the chassis Force a manual switchover by executing the ACLI notify berpd force command Power cycle the active Oracle Communications Session Border Controller peer apEnvMonI2CFailNotification

Media Link Alarms

Media link alarms include the following:

  • Major

    If the Oracle Communications Session Border Controller’s media link goes from being up to being down, it is considered a major alarm. This alarms applies to both slots 1 and 2 on the Oracle Communications Session Border Controller. A message appears on the front panel of the Oracle Communications Session Border Controller’s chassis, similar to the following: 

    MAJOR ALARM
Gig Port 1 DOWN
  • Minor

    If the Oracle Communications Session Border Controller’s media link goes from being down to being up, it is considered a minor alarm. This alarm applies to both slots 1 and 2 on the Oracle Communications Session Border Controller.

Power Supply Alarms

The following table describes the power supply alarms

Alarm Alarm ID Alarm Severity Cause(s) Log Message Actions Trap Generated
PLD POWER A FAILURE 65540 MINOR (-10) Power supply A has failed. Back Power Supply A has failed! 1. Check if the power supply is powered down. 2. Check whether the physical layer is functioning properly. This includes the server hardware, any attached peripherals, and the cabling. apSysMgmtPowerTrap
PLD POWER A UP 65541 MINOR Power supply A is now present and functioning. Back Power Supply A is present! Run Hardware Diagnostics to rule out any issues, if there was no power fluctuation at datacentre. apEnvMonPowerSupplyStatusEntr
PLD POWER B FAILURE 65542 MINOR (-10) Power supply B has failed. Back Power Supply B has failed! 1. Check if the power supply is powered down. 2. Check whether the physical layer is functioning properly. This includes the server hardware, any attached peripherals, and the cabling. apSysMgmtPowerTrap
PLD POWER B UP 65543 MINOR Power supply B is now present and functioning. Back Power Supply B is present! Run Hardware Diagnostics to rule out any issues, if there was no power fluctuation at datacentre. apEnvMonVoltageStatusEntry

Note:

If the system boots up with one power supply, the health score will be 100, and no alarm will be generated. If another power supply is then added to that same system, this same alarm will be generated, but the health score will not be decremented.

Physical Interface Card Alarms

The following table describes the physical interface card alarms.

Alarm Alarm ID Alarm Severity Cause(s) Log Message Actions Trap Name
PHY0 Removed 65550 MAJOR Physical interface card 0 was removed. PHY card 0 has been removed. Check for loose connection and reseat the card. Run HW Diagnostics if this was not performed by administrator. apEnvPhyCardStatusEntry

PHY1 Removed 65553 MAJOR Physical interface card 1 was removed. PHY card 1 has been removed. Check for loose connection and reseat the card. Run HW Diagnostics if this was not performed by administrator. apEnvPhyCardStatusEntry
PHY1 Inserted 65554 MAJOR Physical interface card 1 was inserted. None N/A apEnvPhyCardStatusEntry

Transcoding Alarms

The transcoding feature employs several hardware and software alarms to alert the user when the system is not functioning properly or overload conditions are reached.

Graphic Window Display

The Environment display lets you scroll through information about the operational status of the hardware displayed in the Oracle Communications Session Border Controller chassis’s graphic window. For example, you can view hardware- and link-related alarm information, highest monitored temperature reading, and fan speed.

The graphic display window presents the following Environment information in the order listed:

Alarm state
temperature
fan speed
  • alarm state: HW ALARM: X (where X is the number of hardware alarms, excluding ENVIRONMENTAL SENSOR FAILURE) and LINK ALARM: X (where X is the number of link down alarms)
  • temperature: format is XX.XX C, where XX.XX is the temperature in degrees
  • fan speed: XXXX, where XXXX is the RPM of the failing fan on the fan module

For example:

HW ALARM: 1
LINK ALARM: 2
TEMPERATURE: 38.00 C
FAN SPEED: 5800

From this display, pressing Enter for the Return selection refreshes the information and returns you to the main Environment menu heading.

Note:

Environmental sensor failure alarms are not displayed in the graphic display window on the front panel.

Fan Stopped Alarm

The fan stopped alarm presents the following in the graphic display window:

X HW ALARM(S) (where X indicates the number of HW alarms that exist on the system)

Temperature High Alarm

The temperature high alarm presents the following in the graphic display window:

X HW ALARM(S) (where X indicates the number of HW alarms that exist on the system)
