CR-SEH
Configuring the CR-SEH
The network that the CR-SEH is connected to must be compatible with 10/100BaseT products. Before
connecting a default configured CR-SEH to an active network that does not have a BOOTP or DHCP
server, ask the network system administrator for an IP address for the CR-SEH that will not cause any
problems on the network.
Setting IP Addresses
CR-SEHs 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 CR-SEHs 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 CR-SEH. If a DHCP server is present
on the network, the IP address can be set up through it.
The Master CR-SEH can obtain its IP address through a DHCP server residing on the Master CR-SEH’s
local network. The slave CR-SEHs receive their IP address through the Master CR-SEH from the DHCP
server on the Master CR-SEH’s local network. If the slave CR-SEH cannot establish a link with the
master CR-SEH (due to different network numbers or some other configuration setting), the slave CR-
SEH 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 CR-SEH 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 CR-SEH obtain its
IP address from the DHCP server.
IP Hunter Utility
The CR-SEH 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.
