• Monday, December 14 starting at 10:00 P.M.  - All ETS managed Linux servers (excluding the CSE research networks) will be patched. These systems will reboot at 7:30AM on December 15^th. Please make sure your systems are powered on, and on the network, before the patch window opens. Further, it is recommended that all files be saved before the patch window opens and that all users log off before the reboot time.

• Thursday, December 17 from 6:00 to 8:00 P.M.  - ETS will remove FastX 2 from all COE Linux systems except for systems running Red Hat Enterprise Linux 6 (RHEL 6) or CentOS 6.  FastX 3 is already installed on all COE Linux systems that have FastX 2.  If you are not currently using FastX 3, please install and switch to it before 6pm on December 17 (unless you are connecting to a RHEL 6 or CentOS 6 system).  Instructions for obtaining and configuring FastX 3 can be found here - https://wiki.engineering.osu.edu/display/DOCS/FastX+v3+Install+Instructions. FastX 2 and FastX 3 clients can co-exist on the same system and you can have both versions installed.

If you're unsure if the Linux system you connect to is running RHEL 6 or CentOS 6, you can open a command line and type cat /etc/redhat-release (the file exists on both RHEL 6 and CentOS 6).  If you are using RHEL 6 or CentOS 6 you'll something similar one of the lines below in the command's output.  If you receive an error when typing the command, you are not running any version of RHEL or CentOS.

• Friday, December 18 from 8:00 to 10:00 A.M - stdlinux and faclinux servers will be offline for maintenance. Please make sure you are logged out prior to the outage window to avoid losing data.

• Monday, December 28 7:00 A.M. to Tuesday, December 29 5:00 P.M.  Power to the ETS Data Center in Dreese Lab 886, 894 & 898 will be shut off to facilitate the installation of a new Uninterruptible Power Supply (UPS). For those with research equipment in these rooms, please plan to shut your equipment down before 7:00AM on the 28th. Any long running experiments/computations should be scheduled so they are complete well before this time. If the equipment is still up at 7:00AM, our Systems Administrators will physically power the equipment off. Starting at 7:00AM on Monday, 12/28 all systems housed in the mentioned three rooms will be shutdown and at 8:00AM the power to the rooms will be turned off.

The power to the room will not be restored until the UPS installation and startup is completed on Tuesday 12/29. Once the UPS is back online and stable we will work to bring all the equipment back up as quickly as possible.

If you need help shutting your equipment down safely please enter a request at http://go.osu.edu/ets or email the ETS Help Desk at etshelp@osu.edu.
