Chapter 2 Setup and Installation
Set Up the Switch for the First Time
IP Assignment Mode The IP assignment mode determines if the switch IP information will be
manually assigned (static) or be automatically assigned by a Dynamic Host
Configuration Protocol (DHCP) server. The default is Static.
We recommend that you select Static and manually assign the IP address for
the switch. You can then use the same IP address whenever you want to access
the device manager.
If you select DHCP, the DHCP server automatically assigns an IP address,
subnet mask, and default gateway to the switch. As long as the switch is not
restarted, the switch continues to use this information, and you can use the
same IP address to access the device manager.
Note If you manually assign the switch IP address and your network uses a
DHCP server, make sure that the IP address that you give to the switch
is not within the range of addresses that the DHCP server will
automatically assign to other devices. This prevents IP address
conflicts between the switch and another device.
IP Address The IP address is a unique identifier for the switch in a network. The format is
four numbers separated by periods. Each number can be from 0 to 255.
This field is enabled only if the IP assignment mode is Static.
Note Make sure that the IP address that you assign to the switch is not being
used by another device in your network.
The IP address and the default gateway cannot be the same.
The IP addresses in the 10.0.0.0 network cannot be configured on the
switch.
Subnet Mask List The subnet mask is the network address that identifies the subnetwork (subnet)
to which the switch belongs. Subnets segment the devices in a network into
smaller groups. The default is 255.255.255.0.
This setting is enabled only if the IP assignment mode is Static.
