Brief Scheduled Outage for EECS Wireless

by

There will be a brief scheduled outage of all EECS wireless networks on this Friday, September 19th, in order to perform a minor configuration change which will require a reboot of the wireless controllers. The maintenance will begin at 6:30AM and is expected to be complete by 7AM.

This is scheduled to coincide with a related maintenance being performed by IST on their wireless controllers, which serve the rest of campus. Information on the IST scheduled outage can be found at ucbsystems.org, CMR #3214.

This outage will affect all wireless networks (including AirBears) in all EECS locations: Soda, Cory, Sutardja Dai, and Blum Halls, as well as the Calvin Lab and the BWRC, and some areas of the Hearst Memorial Mining Building.

For questions, concerns, or comments, please contact help@eecs.berkeley.edu.

Thanks,

EECS Wireless Network Upgrades, Outages, and Changes

by

On Saturday, August 30th, between 11AM and 6PM, we will be replacing the EECS wireless controllers with newer models. As a result, all wireless networks in all EECS locations will be offline during the upgrade. The wired network will not be affected.

Networks affected: EECS, EECS-Secure, EECS-Open, EECS-Guest, EECS-Robonet, EECS-Viper, 326capture, 540capture, AirBears, AirBears2, attwifi.

Locations affected: Soda Hall, Cory Hall, Sutardja Dai Hall, Calvin Lab, Blum Hall, Sibley Auditorium, Hearst Memorial Mining Building

Additionally, the following changes are being made to EECS wireless network offerings:

EECS: this network will be renamed to EECS-PSK and the security protocol will be changed from WEP to WPA2-PSK, which is much more secure. The preshared key (password) used to access the network will not change.

EECS-Open: this network will no longer be offered.

326capture and 540capture: these networks are being merged into a single network called EECS-Capture. The preshared key will not change.

Simons: the Simons SSID will no longer be offered.

Please direct any questions or concerns to help@eecs.berkeley.edu.

Responses Needed for Changes to “EECS” and “EECS-Open” Wireless Networks

by

In the near future, we will be making some changes to the EECS department’s wireless network offerings. The largest will be centered around the current “EECS” WEP network; proposed alterations include a switch to WPA2 and a probable name change for the SSID. We are also planning the removal of the “EECS-Open” unencrypted network.

To minimize any potential impact on classes, research, and projects, we must find out who relies specifically upon the “EECS” WEP network or the “EECS-Open” unencrypted network, especially for any instructional or research purposes. If you or your group fits this description, please get in touch by sending an e-mail to help@eecs.berkeley.edu with a short description of your use case so that we can keep in touch with you about the proposed changes and ensure that they will not have any adverse affect on your project.

To avoid a mid-semester change in service, we hope to make these changes around Labor Day, so please contact us quickly if you use the “EECS” or “EECS-Open” networks.

Thank you,

EECS/IRIS Network Group

UPS Maintenance in SDH 158

by

At 11 AM today we will be replacing batteries and performing maintenance on a faulty UPS located in our primary server and network room for Sutardja Dai Hall. No service interruptions are expected. However, in the event of a failure, there may be a ~5 minute loss of wired and wireless networking in Sutardja Dai Hall, as well as a loss of the NetApp network file storage for the EECS Instructional Labs. The maintenance is expected to last for approximately one hour, but two have been allotted in case of complication.

Cory Hall 5th Floor Switch Failure

by

On Friday night, we experienced a failure of an access switch on the 5th floor of Cory Hall. This has resulted in a loss of connectivity to approximately one third of the wired devices and wireless access points on the floor. We are currently in the process of replacing the switch and should restore full connectivity by 12:30 PM.

EECS Network Scheduled Outage on Mar. 29 2014

by

We will be having a large scheduled outage of the EECS network in order to physically relocate some core devices as Phase Three of a project to overhaul the EECS network core. This maintenance will occur between 10AM and 6PM on Saturday, March 29, 2014. We do not anticipate the outage to last for the full eight hours, but extra time has been allotted in case of complications.

Expected impacts of this outage include:

– Internet connectivity to all EECS Wired buildings* will be offline
– Soda Hall wired and wireless networking will be entirely offline
– BWRC will be isolated from EECS and unable to access the Internet or EECS network resources
– Wireless networking in EECS Airspace** will be unavailable (the networks will continue to be visible in some locations, however the underlying network services will be offline)
– EECS Wired buildings other than Soda Hall and BWRC should retain connectivity and access to EECS network resources (filers, AD, etc.), but to reiterate, the Internet connection will be unavailable.

We apologize for any inconvenience that this maintenance will cause. For any questions or concerns about the maintenance, please email networks@eecs.berkeley.edu.

Thank you, IRIS Network Group

*EECS Wired buildings are Soda, Cory, and Sutardja Dai Halls, and the BWRC

**EECS Airspace includes Soda, Cory, Sutardja Dai, Calvin, and Blum Halls, as well as the Sibley Auditorium, Hearst Memorial Mining Building, and BWRC
