Configuring the Switch

48-Port 10/100 + 4-Port Gigabit Switch with WebView and Power over Ethernet

The Switch provides more efficient throughput for large
sequential data transfers by supporting jumbo frames
up to 10240 bytes on the Gigabit ports and mini jumbo
frames on the 10/100Mbps ports. Compared to standard
Ethernet frames that run only up to 1.5 KB, using jumbo
frames significantly reduces the per-packet overhead
required to process protocol encapsulation fields.
To use jumbo frames, both the source and destination
end nodes (such as a computer or server) must support
this feature. Also, when the connection is operating at
full duplex, all switches in the network between the two
end nodes must be able to accept the extended frame
size. And for half-duplex connections, all devices in the
collision domain would need to support jumbo frames.
Enabling jumbo frames limits the maximum threshold for
broadcast storm control to 64 packets per second.

Admin > Firmware Upgrade
Downloads or uploads Switch firmware files from a
TFTP server. The Switch allows the runtime software and
diagnostic boot files to be upgraded. You must specify
Upgrade to download a new firmware file or Backup to
save a firmware file to the server.
Select the Upgrade or Backup option, then the file type
from the drop-down menu, either Software Image or
Boot Code. Enter the IP address of the TFTP server, specify
the file name of the software on the server, and then click
Save Settings.
Admin > HTTP Upgrade
Download new Switch runtime software from the local
web management PC.
