9.2 Monitoring Device Status
The device status provides an overview of the overall condition of the Switch.
Many process visualization systems record the device status for a device in
order to present its condition in graphic form.
The Switch enables you to
D signal the device status out-of-band via a signal contact
(see “Monitoring the Device Status with a signal contact” on page 177).
D signal the device status by sending a trap when the device status
changes.
D detect the device status in the Web-based interface on the system side.
D query the device status in the Command Line Interface.
The device status of the Switch includes:
D Incorrect supply voltage,
the failure of at least one of the two supply voltages
or a permanent fault in the Switch (internal supply voltage).
D The temperature threshold has been exceeded or has not been reached.
D Removing a module (at modulare devices).
D Removing the ACA.
D Failure of a fan (MACH 4000).
D The defective link status of at least one port. With the Switch, the indica-
tion of link status can be masked by the management for each port (see
“Displaying connection error messages” on page 70). Link status is not
monitored in the delivery condition.
D HIPER-Ring event:
the loss of redundancy guarantee (in Redundancy Manager mode). Ring
redundancy is not monitored in the delivery condition.
D Redundant Ring/Netcoupling event:
the loss of redundancy guarantee. Ring redundancy is not monitored in
the delivery condition.
In Stand-by mode the Switch reports additionally the following conditions:
– the faulty link status of the control line
– partner device is in stand-by mode
