Wired Networking

Currently power outlets in the 4th flr. restrooms are on a common electrical circuit with power in the 4th communications closet. Space and facilities team would like to shutdown the communications closet for about or less than 30 minutes to move these outlets onto a new circuit.

This will prevent outside areas from accidentally tripping the circuit feeding the communications closet. The network switches serving in the area of 4th floor will be affected by this move. Only users in 4th floor of Cory will be affected by this. Since wireless APs in 4th floor were fed by the switches in that closet, you may experience wireless outages if you are located in 4th floor area.

We have UPS and hopefully will be able to carry the load but you may experience some of intermittent wired and wireless conductivity issues for a short period of time.

If you have any concern, please send email to networks@eecs

We are continuing to do switch maintenance. The EECS switches(in 4A, 4B, 3B) are located at 4th and north east side of 3rd floor of Soda will experience brief outages on Thursday, Aug 25, 2011 beginning at 6:00a.m. due to network maintenance.

The wired network will be offline and users will experience a brief (couple minutes) outage while the switches are rebooted to apply new firmware. Since wireless networking devices are also fed by that device, wireless network will experience a brief outage as well.

We have received the replacement part from our vendor for the malfunctioning module in the edge router. Installing the new part will result in reduction of bandwidth for a few minutes, but we do not expect a complete outage.
