Power Outages
Many IET Services Susceptible
by Autumn Bouck
 
You AskedYou probably have questions about how to protect your computer equipment and electronic data when the power goes out. You might also want to know what Information and Educational Technology (IET) services will be available when the power is out, and for how long. This information is available on the UC Davis Unplugged Web site and the IET power outages page at http://iet.ucdavis.edu/poweroutages/. Here are some highlights:

Q. Are all IET departments located on campus where they will be exempt from blackouts?
A. No. In fact, many IET services are located off-campus on Chiles Road and are not exempt from rotating blackouts like the core campus. This building is in Block 14 for rotating blackouts, and they expect to have several blackouts this summer. For detailed information about which services are affected by these blackouts, see the Chiles Road services table on the IET Power Outages page.

Q: Are any servers such as DaFIS, Banner, PPS, email or AFS located at the Chiles facility?
A: No. All of these servers are located in the Data Center, which is on campus. In case the power does go out on-campus, a generator will backup administrative systems but, unfortunately, when the campus network goes down, you will not be able to access them. For this reason, it is important to save your transactions as often as possible so you do not lose your work. If there are problems with the generator, the systems will need to be shut down. For a more details on which servers are located in the Data Center, and how long they will be available in case of a power outage, see the Data Center Power Outage plan.

Q: How long will the campus network be available?
A: The campus network has battery power for 40 minutes when the power goes out. After 40 minutes, a backup generator will be turned on and provide power to both the campus network and the voice switch. Unless your building has a generator that powers the building network, you will have long enough to turn off your server and finish DaFIS, Banner, and PPS transactions, but not much longer.

Q: Once the power comes back on, will the network be available right away?
A: The network and database servers (DaFIS, Banner, PPS, etc.) may take some time to be restored, especially if they are affected by power surges or other complications. Service should be restored within 20-30 minutes of power being restored.

Q: Will wireless services in Shields Library, the MU, and King Hall be available?
A: In the event of a power outage, these services will continue for 20 minutes.

Q: If the power is out on campus, will I still be able to connect to the Modem Pools?
A: Yes. The modem pools will be operational during a core-campus power outage.

Q: If the power goes out, will I still be able to use my telephone?
A: Yes. Phones both on and off campus will still ring and have a dial tone. If the phone is electronic, the display and lights probably will not work. For more information about single and multi-line phones, both on and off campus, see the IET Power Outages site.

Q: Will I still be able to get and retrieve voice mail messages during a power outage?
A: Yes. The voice mail system has batteries for up to eight hours. For more details, see telecommunications information on the IET Power Outages site.


Q: Will power outages affect my cellular phone?
A: No.

Q: What kinds of things can I do to conserve energy?
A: There are serveral things you can do to save energy. One easy way to conserve energy is to turn off computer peripherals (scanners, zip drives, printers, etc.) except for when are using them. You can also change the settings on your computer and monitor to use the least amount of energy and automatically turn them off your when you are away from your desk. For more tips on energy conservation, see the Unplugged Web site.

Q: What can I do to protect my computer equipment and data in the event of a power outage?
A: Most of the things you can do to protect your equipment need to be done when the electricity is still on. These things include backing up your system, saving your work, using UPSs or surge protectors, and checking batteries. See the Unplugged Web site for more information on these options.

Q: Should I buy a UPS?
A: A UPS (Uninterruptible Power Supply) is basically a battery that charges when the power is on and kicks in when the power goes out. It also protects your computer from power surges or spikes. There are several different kinds of UPSs; the least expensive allow you time to safely shut down your system. More expensive models will allow anywhere from 20 minutes to several hours worth of power. The decision to purchase a UPS is based on individual and departmental needs. Before deciding, you should know that the campus network may not be available 20 minutes after a power outage, so if the work you intend to do is network-based, a UPS might not benefit you. If a device does have an UPS or other type of battery back up, it might not need to be shut down during an outage.

Q: I provide computing support to my entire department. Is there a place where I can find more technical information?
A: Yes. The Technology Support Program has this information on their Web site.
