Hardware

Note There are several alerts that are not displayed on some models due to hardware differences:
  1. Right hard disk and Left hard disk: Some models have only one disk, so disk failure renders the unit inoperable.
  2. Right power supply and Left power supply: Some models have only one power supply, so a power supply failure renders the unit inoperable.
  3. Right power supply fans and Left power supply fans: Some models have only one power supply fan, so a fan failure renders the unit inoperable.

The Hardware section displays the following information:

  • CPU: A critical alert is triggered if there are problems with the appliance CPU that could affect the stability of your system.
  • Disk mirroring: A warning or a critical alert is triggered, depending on the severity of a problem with the hard disks, that will affect the stability of the Email Appliance.
  • Right hard disk: A warning alert is triggered if there is a problem with the right hard disk that will affect the stability of the Email Appliance. A critical alert is triggered if the right hard disk fails. This is the rightmost disk when the Email Appliance is viewed from the front. If it becomes necessary to replace this disk, the alert continues to be displayed on the System Status tab until the RAID controller has finished rebuilding the new drive. This could take several hours, depending on the amount of data and the system load at the time.
  • Left hard disk: A warning alert is triggered if there is a problem with the left hard disk that will affect the stability of the Email Appliance. A critical alert is triggered if the left hard disk fails. This is the leftmost disk when the Email Appliance is viewed from the front. If it becomes necessary to replace this disk, the alert continues to be displayed on the System Status tab until the RAID controller has finished rebuilding the new drive. This could take several hours, depending on the amount of data and the system load at the time.
  • Right power supply: A warning alert is triggered if the right power supply is removed. A critical alert is triggered when the right power supply is not functioning properly or is disconnected. In both cases, as long as the left power supply is operating normally, the appliance will continue to process mail. This is the rightmost power supply when the Email Appliance is viewed from the rear.
  • Left power supply: A warning alert is triggered if the left power supply is removed. A critical alert is triggered when the left power supply is not functioning properly or is disconnected. In both cases, as long as the right power supply is operating normally, the appliance will continue to process mail. This is the leftmost power supply when the Email Appliance is viewed from the rear.
  • Right power supply fans: A critical alert is triggered if one or more of the right power supply fans in the appliance has failed.
  • Left power supply fans: A critical alert is triggered if one or more of the left power supply fans in the appliance has failed.
  • System fans: A critical alert is triggered if one or more of the system fans in the appliance has failed.
  • System memory: A warning alert is triggered if the appliance is consuming over 90% of available physical memory. This may indicate that it is handling unusually heavy mail volumes. Slower mail delivery should be expected.
  • System memory usage: A warning alert is triggered when 98% of physical memory is used.
  • System temperature: A warning or critical alert is triggered, depending on how much the appliance exceeds its normal temperature range.
  • System voltage: A warning or critical alert is triggered, depending on how far outside of its normal voltage range the appliance is operating.
