If they are not listed in CAESAR on the primary scheduled component (i.e. lecture rather than discussions), they will not be included on the evaluation form. Please make sure to review all instructor/TA assignments for your department's classes to ensure the correct individuals are evaluated, and to prevent issues with missing instructors/TAs.

The use of network distribution devices on CSUS network is not allowed. These devices include hubs, repeaters, switches, routers, firewalls, and wireless access points. While these devices might work just fine when used in a home office environment, they are not intended for use as part of a large network such as CSUS network and may have adverse effects on the security and reliability of your devices. The supported method of connecting multiple machines to CSUS network is to have a dedicated network drop installed for each machine. This gives you greater reliability and a higher quality of network service than using a hub, and it will not cause service problems for other users of the network. Options for adding devices that require network connectivity are:
Information Resources and Technology (IR&T) reserves the right to turn off network service to illegal devices (and any machines connected to such a device) in order to keep the network running smoothly for everyone.
