Note
If you elect to assign the IP address using DHCP, it is advisable to set the
lease time on the DHCP server/router to a value of at least a day.
Otherwise, you may notice that the ioSafe R4 IP address may change even
when it has been powered down for only a few minutes. Most DHCP
servers allow you to assign a static IP address for specified MAC addresses.
If you have this option, this would be a good way to ensure your ioSafe R4
maintains the same IP address even in DHCP mode.
►
SPEED/DUPLEX MODE
If you have a managed switch that works best if the devices are forced to a particular speed or
duplex mode, you can select the desired setting. It’s advisable to keep t he setting in auto-negotiation
mode otherwise.
►
MTU
In some network environments, changing the default MTU value may fix throughput problems. It’s
advisable to leave the default setting otherwise.
►
VLAN SETTING
Virtual Local Area Network, or VLAN, allows devices residing on different segments of a LAN to
appear in the same segment, or conversely allows devices on the same switch to behave as though
they belong to a different LAN.
If you wish to use the ioSafe R4 in a VLAN environment, select the
Enable VLAN support
checkbox and input a numeric VLAN tag. You will need to reboot the ioSafe R4 for the VLAN
function to take effect.
