Configuration using SNMP
The Simple Network Management Protocol (SNMP V.1 as specified in RFC
1157) allows monitoring and configuration of the devices on a network from
a single central instance.
Detailed information on the configuration of ELSA devices with SNMP can be
found in the electronic documentation on the CD.

New firmware with FirmSafe
The software in the ELSA device is constantly being updated. We have fitted
the devices with a flash ROM which makes child's play of updating the
operating software so that you can enjoy the benefits of new features and
functions. No need to change the EPROM, no need to open up the case:
simply load the new release and you're away.
3.6.1
This is how FirmSafe works
FirmSafe makes the installation of the new software safe: The used firmware
is not simply overwritten but saved additionally in the device as a second
firmware.
Of the two firmware versions saved in the device only one can ever be active.
When loading a new firmware version the active firmware version is not
overwritten. You can decide which firmware version you want to activate
after the upload:
'Immediate': The first option loads the new firmware and activates it
immediately. This can result in the following situations:
The new firmware is loaded successfully and works as desired. Then
all is well.
The device no longer responds after loading the new firmware. If an
error occurs during the upload, the device automatically reactivates
the previous firmware version and reboots the device.
'Login': To avoid problems with faulty uploads there is the second option
with which the firmware is uploaded and also immediately booted.
In contrast to the first option, the device will wait for five minutes
until it has successfully logged on. Only if this login attempt is
successful does the new firmware remain active permanently.
