SITE AVAILABILITY

This is a departmental/LTS shared PC teaching site. It is available for public use when not scheduled for classes or labs. Reservations for classes may be made through the Chemistry Department. Select Site Hours to determine this site’s operating hours or for a listing of other computing locations.

HARDWARE

The lab contains (18) Dell GX620 P4 3.4GHz computers with 80GB hard drives, 1.0GB memory, CDRW/DVD, and 1.44MB floppy. One computer is designated as the instructor computer and will project when selected from the touch-screen control.

NETWORK - PRINTING

All computers are connected via a 100Baset to the Backbone Network. The HP4250 printer located in this room can be accessed from any computer within this room.

USAGE OF THE AUDIO VISUAL EQUIPMENT

1. Power up the equipment rack and projector by touching the AMX touch-screen located on the wall to the right of the instructor station computer (two touches may be required). Please note that the projector turns on gradually and you may not see an image for 30 seconds. A message will display as the system turns on. Please be patient. The switch for the projection screen is located near the door.
2. Power up the computer CPU and monitor if being used (buttons on monitor and computer). You must complete a LAN login to use a public computer by typing your user name and password in the appropriate fields in the opening dialog box. Remember to log out when you are done. See the "LTS Guide to Public Computing Sites and Classrooms" for additional information onuse of public sites.
3. Adjust the volume by touching the Volume up or down arrows on the AMX touch-pad. The “mute” button at the bottom of this control turns off the sound.

POWER DOWN THE EQUIPMENT

1. Before leaving the room you MUST logout of the system. Double click the bright yellow exclamation point icon on the Windows Desktop. You may then select "Shutdown" or "Logout": one button clears the system and leaves the computer ready for the next user; the other turns off the computer. If you make no selection your account will be logged out and the system will return to the login screen. If you fail to logout, the next user of the system will have access to your account and files.
2. Press "System Power Off" button on the AMX touch screen to turn off the projector and related equipment. A confirmation message will be displayed. Select "Yes" to turn off the system.

PROBLEMS

If you have hardware problems, call the Library and Technology Help Desk at X8HELP (X84357), and report the position letter of the failing unit and the problem. Call the Chemistry Department’s operational contact at x83470 if printing supplies are needed.

POTENTIAL PROBLEM AREAS

• You must login to every public site computer. If you find a computer that is not displaying the login screen, the previous user failed to logout. Double click the bright yellow exclamation point icon on the Windows Desktop, select "Logout", and wait for the login screen.
• The system is currently set to turn off automatically at 12 PM EST if anyone fails to turn it off. Should the system turn off inappropriately users may turn it back on with the AMX touch panel although there will be a delay while the system resets.
• Note that the projector does not turn on instantly. It can take as long as 30 seconds for a picture to become visible. Please be patient when selecting inputs.
• If there is no sound, check the audio mute button and the volume up arrow on the AMX touch-pad.
• If there is no picture be sure that "picture off" has not been selected
