AirBears Scheduled Outage, Soda and Cory Halls, June 10, 6:30-7:30am

by

SCHED OUTAGE AirBears at Soda and Cory Halls Wednesday, June 10, 2009 06:30am – 07:30am

Equipment: AirBears Access Manager, soda1am
Location: AirBears at Soda and Cory Halls
Date: Wednesday, June 10, 2009 Start: 06:30am End: 07:30am

Description:
In planning for the network equipment and cabling moves from Evans Hall to
Saturdja Dai Hall, a new path needs to be established from soda1am to
the router interface. To accomplish this, this network will be out of
service for about 20 minutes. There will be no network connections
via “AirBears” in Soda and Cory Halls during the outage, but the network
signal will still continue to be broadcast.

Although the outage should only take about 20 minutes, additional time (up
to 1 hour) has been scheduled for unforseen challenges.

Updates will be posted on the [IST Service Status Page](http://ucbsystems.org/).

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.
