43 You can change the LAN Port Speed and Duplex settings. The default setting is for
the switch to automatically negotiate a speed and duplex that matches your
current network. However, you can select a setting between 10 and 100Mbps and
between Half and Full Duplex.
NOTE: The LAN Port Speed and Duplex settings will not work for the NJ240FX
because you cannot configure the fiber uplink. This field will be grayed out if
you are using the Configuration Management software with an NJ240FX.
44 You can change the Maximum Frame Size setting if your network uses
non-standard frame sizes.
The standard maximum size of an Ethernet frame is 1518 bytes. If a VLAN tag is
added, the maximum size increases to 1522 bytes. As a result, this is the default
setting. If your network uses larger frames, you can select the 1536 byte option.
