8.  After rebooting, set the SNMP Write Lock switch back to NORMAL.  The 
previously made settings to the application modules will be active. 
 
NOTE 
When removing an SNMP card with the SNMP Write Lock enabled (set to LOCKED), 
current application modules settings will not be changed.  Never power-cycle the chassis 
while the SNMP Write Lock is enabled (except during Step 5 in the preceding process).  
This will revert the SNMP card back to its original factory settings.  (iView² should only be 
accessed with the SNMP Write Lock disabled.) 
Using Telnet 
The iMediaChassis series supports Telnet for remote configuration.  All 
configurations that can be performed via the serial port can also be 
performed using Telnet (except serial passwords).  Use only one Telnet 
session at a time.  Do not use an RS-232 serial session and a Telnet session at 
the same time. 
About DHCP 
DHCP Disable (Static IP Addressing) 
DHCP is disabled in the default configuration. Initially, modules are assigned 
a Static default IP Address of 10.10.10.10.  Changes to the Static IP Address 
can be added manually through iConfig, an RS-232 Serial session, or Telnet.  
The changes will be initiated following reboot of the module 
 
DHCP Enable (Dynamic IP Addressing) 
If a DHCP server is present on the network and DHCP is enabled, the DHCP client 
will initiate a dialog with the server during the boot up sequence.  The server will 
then issue an IP address to the management card.  Once the new IP address is 
received, the SNMP Management Module will reboot so that the new IP address will 
take effect.  Refer to the About Serial Port Configuration for more information about 
Enabling/Disabling DHCP.  When there is no DHCP server on the network, use 
iConfig or serial configuration to manually set the IP addresses. 
 
When DHCP is enabled, the IP address (default 10.10.10.10 or user configured) is 
saved.  When DHCP is disabled, the saved IP address will be reinstated and the 
device will reboot. 
 
DHCP servers give out lease times: devices renew their leases based on the 
administrator-specified time.  If a device cannot renew its lease, and the lease 
expires, the device will be given the IP address 10.10.10.10 and will reboot.
