OPERATION OF THE PRODUCT
After going through the installation steps as described above, the device is
ready to use.
The DEV 5071 can be monitored locally; additionally there are the
possibilities for the surveillance and for the control of the product via the
Web Interface and/or via SNMP. Before the operation of the device via each
of these possibilities is explained, the different device operation modes are
described:
5.1
MODES OF OPERATION
Local Mode and Remote Mode define the manner how the device is
controlled.
Note:
Changing the operation mode can only be done via Web Interface
(please refer to chapter 5.4.2) and via SNMP (chapter 5.5.4.2.1), only.
5.1.1
Local Mode
In Local Mode the device executes commands (i.e. the change of settings),
which are issued via the Web Interface.
The communication to the SNMP remote interface is disabled for modifying
the settings of the device, but open for surveillance and status queries.
5.1.2
Remote Mode
The Remote Mode is implemented for operation via SNMP.
In Remote Mode, the status of the power supplies is still indicated via the
LEDs at the device and via Web Interface, but the control functionality of the
Web Interface is disabled.
5.2
INITIALIZATION OF THE DEVICE
The device performs a health check and a configuration check during power
up or after a reboot e.g. via Web Interface. This takes about 60 seconds,
there is no manual configuration necessary, all settings (including the
operation mode of the device,
except
possible switched off power supply
modules) after power-up or after a reboot are the same as before shut down.
However -as explained in chapter 4.2.4- it is
highly recommended
to reboot
the device after power up!
5.3
OPERATION AT THE DEVICE
Beside the reset push button at the CPU module (please refer to
chapter 3.2.2), there are no elements to be operated. The status of the
power supply modules is indicated via LEDs, which were already presented
in chapter 3.2.1.
