9.2 Monitoring the 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
X signal the device status out-of-band via a signal contact
(see on page 13 "Monitoring the device status via the signal contact")
X signal the device status by sending a trap when the device status changes
X detect the device status in the Web-based interface on the system side.
X query the device status in the Command Line Interface.
The device status of the Switch includes:
X Incorrect supply voltage,
the failure of at least one of the two supply voltages
or a permanent fault in the Switch (internal supply voltage).
X The temperature threshold has been exceeded or has not been reached.
X The removal of a module (for modular devices).
X The removal of the ACA.
X Failure of a fan (MACH 4000).
X 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
on page 72 "Displaying connection error messages"). On delivery, there
is no link monitoring.
X Event in HIPER-Ring:
The failure of the redundancy (in redundancy manager mode). On deliv-
ery, there is no ring redundancy monitoring.
X Event in the Ring/network coupling:
failure of the redundancy. On delivery, there is no ring redundancy moni-
toring.
The following conditions are also reported by the Switch in standby mode:
– Incorrect link status of the control line
– Partner device is in standby mode.
The management setting specifies which events determine the device status.
