Chapter 5 Operating the Cisco ICS 7750
Accessing the System
Installing or Enabling a DHCP Server on Other SPE310s or Other Servers
Do not install or enable a DHCP server on the SPE310 that is running System Manager. You can install or configure DHCP on an external server, provided that
•The external DHCP server is configured to not respond to DHCP or BOOTP requests from Cisco ICS 7750 cards
•If ICS System Manager is providing DHCP services to IP phones or external DHCP clients, the external DHCP server should not be configured to respond to these hosts
•The DHCP IP address ranges of the external DHCP server must not conflict with the DHCP or BOOTP IP address ranges in use by ICS System Manager
Note If you are using a DHCP server on an external server, consult your DHCP server documentation for additional DHCP configuration guidelines.
SSP Error Messages
If you are using Cisco IOS 12.0(5)WC2b on the SSP, and if you are monitoring the system through a console connection to the SAP, error messages similar to the following might be generated as the SSP boots:
%error opening tftp://255.255.255.255/cisconet.cfg (Time out)
%error opening
%error opening tftp://255.255.255.255/ciscortr.cfg (Time out)
This is an expected condition. The system will continue to operate normally without any external intervention.
Best Practices for Using the Cisco IOS CLI
ICS System Manager is designed to communicate with and to monitor the status of all the components in the chassis. To enable ICS System Manager to perform these functions, a configuration program (ICSConfig) guides you through the configuration process. ICSConfig enables you to change key system parameters, such as the IP addresses of system cards, passwords, destination for syslog messages, and Simple Network Management Protocol (SNMP) community strings.
