62 CHAPTER 7: STATUS MONITORING AND STATISTICS You can configure the email address to which you wish the notifications to be sent. However, you cannot change the factory default notification messages for event emails. RMON traps continue to be sent, in addition to any email notifications you may receive. The events that can generate email notification are: ■ Unit powers up. ■ Unit in the stack fails. ■ Fan in the unit fails. ■ A link fails or returns to service - you can select specific links that you wish to receive messages for, for example, a mission-critical link to a server. ■ A security violation occurs. Hardware Status Monitoring Your Switch has a fan monitoring system that will generate fan failure warning messages. Fan failure could potentially reduce the lifetime of the Switch. The monitoring system polls the fan status at periodic intervals while the unit is powered up. Should a failure occur, a warning notification will be generated in one of the following ways: ■ Via the CLI menu: An indication of a general hardware failure will be provided on the Command Line Interface (CLI) through the top-level menu displayed when logging on. For more detailed fault information, you should enter the system summary menu for the device. No device status information is provided when the fans are operational. Figure 15 shows an example CLI screen, while Figure 16 shows an example of an individual unit system summary screen.

TATISTICS
You can configure the email address to which you wish the notifications
to be sent. However, you cannot change the factory default notification
messages for event emails.
RMON traps continue to be sent, in addition to any email notifications
you may receive.
The events that can generate email notification are:
■
Unit powers up.
■
Unit in the stack fails.
■
Fan in the unit fails.
■
A link fails or returns to service — you can select specific links that you
wish to receive messages for, for example, a mission-critical link to a
server.
■
A security violation occurs.
Hardware Status
Monitoring
Your Switch has a fan monitoring system that will generate fan failure
warning messages. Fan failure could potentially reduce the lifetime of the
Switch.
The monitoring system polls the fan status at periodic intervals while the
unit is powered up.
Should a failure occur, a warning notification will be generated in one of
the following ways:
■
Via the CLI menu:
An indication of a general hardware failure will be provided on the
Command Line Interface (CLI) through the top-level menu displayed
when logging on. For more detailed fault information, you should
enter the
system summary
menu for the device. No device status
information is provided when the fans are operational.
Figure 15
shows an example CLI screen, while Figure 16 shows an example of an
individual unit system summary screen.
