SEM910
Configuring the SEM
The network that the SEM is connected to must be compatible with 10/100BaseT products.
Before connecting a default configured SEM to an active network that does not have a BOOTP
or DHCP server, ask the network system administrator for an IP address for the SEM that will
not cause any problems on the network.
Setting IP Addresses
SEMs are shipped from the factory with default settings that include a default IP address of
0.0.0.0 and a default configuration as a slave bridge. In order to set up a wireless link, alternate
IP addresses need to be assigned and one of the SEMs must be configured as a master device. If
a BOOTP or DHCP server is not present a different IP address must be assigned to the SEM. If a
DHCP server is present on the network, the IP address can be set up through it.
The Master SEM can obtain its IP address through a DHCP server residing on the Master SEM’s
local network. The slave SEMs receive their IP address through the Master SEM from the DHCP
server on the Master SEM’s local network. If the slave SEM cannot establish a link with the
master SEM, the slave SEM will need to have its IP address entered manually unless it will be
configured through the console port. If it is desired to configure the slave SEM through a
browser session instead of the console port but use a DHCP server to provide the IP address after
initial setup, a temporary IP address can be assigned manually but the IP address will need to be
reset to 0.0.0.0 to have the slave SEM obtain its IP address from the DHCP server.
IP Hunter Utility
The SEM910 CD has a device detection and IP setting utility named IP Hunter. This utility will
detect all Cirronet Ethernet devices on the local network, even those with no IP address. For
those units without an IP address, IP Hunter can set the IP address and then open a browser
session with that device to allow for further configuration. The IP Hunter will display devices
that already have IP addresses and will open browser sessions with those units, but will not
change the IP address already set.
