Firmware upgrade: EECS border router

by

Tuesday July 14th at 7:00AM, we will be upgrading software on the EECS department border router. During the outage, all EECS networks will be disconnected from the Internet, including Soda, Cory, Sutardja Dai,BWRC, and portions of HMMB. The work should only take a few minutes,but we’re reserving a 30-minute window in case of problems.

Please plan accordingly.

Cory Router to Undergo Code Maintenance

by

On Tuesday July 7th at 6:30am, the main Cory Router will undergo code maintenance till 7am. This will affect ALL network activity in Cory Hall with the exception of a few hard wired ports in 2nd floor campus classrooms which are connected directly to the campus network.

If all goes well, the outage will only be for a few minutes and may not
even be noticed, but there are no guarantees.

BWRC wireless networking maintenance

by

There will be maintenance affecting BWRC
wireless networking starting Thursday
June 25, 2009 at 9:30 am. During the
maintenance, BWRC wireless clients will
not be able to get a new dhcp lease on the
IRIS wireless network. Devices that obtained a
dhcp lease prior to the maintenance will not
be affected. AirBears will not be affected.

Maintenance is scheduled to be completed by
10:30am, but if work goes as planned
it could be completed by 9:40am.

The existing dhcp server at BWRC providing
IRIS wireless support has a corrupted operating
system and will be replaced by another device
during the maintenance.

AirBears Disruption

by

The AirBears access manager serving Soda/Cory/BWRC/HMMB/Sibley malfunctioned; wireless clients were unable to get DHCP leases. The campus Wireless Network Engineer rebooted the controller at 10:40 and the service appears to be operating normally.

Sutardja Dai Hall switch updates

by

We’ve experienced unexpected blade reboots and multicast errors on some of the new switches in Sutardja Dai Hall. Per the vendor’s suggestion, I’ll be upgrading these to a newer software release.

Subnets Affected:
128.32.156.0/24, 128.32.247.0/25, 169.229.14.0/24, 169.229.222.0/23

The code revisions are close, so we expect to be able to perform a hitless upgrade; there should be no perceivable disruption. Nevertheless, I’m scheduling a 45 minute maintenance window (1715-1800) in case of problems.

Planned Sutardja Dai Hall electrical shutdown

by

There will be a temporary shutdown of power on Sat May 2, from 8am to noon to verify Building Automation Function with loss of power.

All network equipment, including wireless, should run on UPS and then emergency power once the main generator kicks in. While we expect no problems, this is the first operational test of the network UPSs.

(Note: All switches successfully remained online over the weekend. May 4, 0900.)
