text field that will display the selected image
filename.
Pressing

board and the next page will display results and verification
of the image being burned.

This page displays non-editable information about the
image validity. The
Image Check
field will display “invalid”
if the image does not correspond to the hardware version.
The
Current Software Version
field shows the old
software version. The
New Software Version
field shows
the new version of the software image.
This page needs to be confirmed in order to continue
image updating. If you are sure that the image version is
appropriate for your device press
Save
.
Fig. II-47: Firmware Check page
If you have confirmed the firmware version, a new page
with firmware update progress will be displayed next.
There are no functions available on this page, just
information about the firmware update procedure. At some
point the connection with the device is being lost and you
need to wait until the firmware will be burned on the
Quadro.
You will not be automatically redirected to the Login page.
To access the Quadro’s Web GUI, you need to connect
Quadro again and login.
Attention:
After the firmware update, all IP phones
attached to the Quadro should be restarted.

Networking Tools
The
Networking Tools
page provides the possibility to check the Internet connection.
Ping
sends four ICMP (Internet Control Message Protocol)
requests with a default size of 64 bytes to the destination (IP
address or host name) specified in the text field
Ping Target
.
The response times are logged, and the round trip time (the
time required from being sent until being received again) is
measured. The minimum and maximum round trip time and its
average as well as the percentage of lost and of received
frames results are displayed in the lower area of the page.
Traceroute
checks the Internet connection by triggering the
routers (hops) that are passed to reach the destination
specified in the
Traceroute Target
text field.
Trace routing
gives feedback on the routers passed by packets on the way
toward the destination and the round trip delay of packets to
these routers.
Attention
: No
Traceroute
is possible if a high priority Firewall
has been enabled (see chapter
).
Fig. II-49: Networking Tools page
For the purpose of tracerouting, several IP packets are sent out. UDP (User Datagram Protocol) is used to send packets and ICMP (Internet Control
Message Protocol) is used to receive information about the routers. In their headers, the TTL (Time To Live) value increases from 1 to 30. When the
first IP frame is received by the first router, its IP address will be returned in its acknowledgement.
