front of the module has to level with the chassis frame) and that the lock becomes
engaged when releasing it.
Next -and if applicable-, the DEV 5072 can be powered up.
If the DEV 5072 was powered up during a power supply module exchange, the new
power supply module is activated automatically (if type and output voltage are
correct). If there were changes on the default configuration (chapter 4.3.1) of the
corresponding module, the current settings are transferred to the new module.
This can be verified easily by checking the settings via the Web Interface.
If the DEV 5072 is upgraded with an additional power supply module, the
surveillance of the power supply is to be enabled via the Web Interface
(chapter 5.4.4.1) or via SNMP (chapter 5.5.4.3.5.11).
4.2.4
Reset of the Device and the Restore of Factory Defaults
During power-up or after a reset of the device, the controller of the DEV 5072
performs a health check and scans the assemblies of the device e.g. to detect,
whether a module is installed in a slot or not. If there is a module installed, the
settings for this slot are transferred to the module.
A reset of the DEV 5072 is necessary only if there were applied elementary
changes, e.g. restoring the factory defaults via Web Interface.
The reset of the device can be performed in three different ways:
1. Reset via the "
Reset
" push button located at the rear side of the chassis
(please refer to the drawing in chapter 4.2.2): Press and hold (e.g. by using a
ballpoint pen) the "
Reset
" button for approximately 3 seconds.
2. Reset via the serial interface when terminating the configuration program
(chapter 4.4.2.2.1).
3. Reset via Web Interface (chapter 5.4.6.4.2).
Note:
During a reset, the device still delivers output voltage, i.e. the power supply
module outputs are not deactivated while resetting the device.
If a power supply module was deactivated via Web Interface (chapter 5.4.4.1)
or via SNMP (chapter 5.5.4.3.5.2), it will be activated after a power cycle or
after a reset!
It takes about 60 seconds after a reset or after a power cycle that the device is
completely accessible again via the serial interface, via Web Interface, and via
SNMP.
If –for any reason– a restore of the factory defaults is required, please proceed
as described in the following:
Usually, the factory settings (chapter 4.3) can be restored via Web Interface (chap-
ter 5.4.6.4.1). If –for any reason– the device is not accessible via Web Interface, the
factory settings can be restored in the following manner:
Press and hold the "
Reset
" push button located at the rear side of the chassis
(e.g. by using a ballpoint pen).
After ~20…50 seconds the yellow LED on the "
Ethernet
" connector starts to blink
(8 times, for ~4 seconds). If the "
Reset
" push button is released during this
blinking, the factory settings are restored and a device reset is initiated.
