They plan to start work around 11am that Friday, and they expect it could take 4 hours, more or less, to replace them all. During that time, wifi access might disappear and reappear. Additionally, when your wireless device tries to reconnect to the newly-replaced access point, you ''might'' be prompted to accept a certificate, and we were informed that you should do so.<br/>

| − | ::JHU Networking has indicated they are testing power transfer equipment in Mason Hall that will affect several buildings, including Malone and Hackerman. They will be cycling power to the buildings, perhaps several times. They expect their outages to be < 10 seconds each.
| |
| − |
| |
| − | ::Our CS IT servers that provide you most of our IT services should remain up and running, since our servers have backup battery power. Unfortunately, the JHU network in the building does not. So, you will probably experience brief network interruptions when the power is cycled by Facilities. And each time the power is out, CS services that you interact with (email, web, home directories, etc.) will be inaccessible due to the building's network being unavailable during the outage times.

| |
| − | ::Faculty who run their own servers in the CS Server Room (MH G-29), please note that if you do not have UPS units in your racks (and most of you do not), you can expect your systems will power cycle each time Facilities cycles power in Malone Hall. Please be aware. PhD students who maintain those systems (and perhaps other systems in the building), please keep that in mind as well.

| − |
| |
| − | ::The CS computing labs' systems (currently, for the summer, all located in G-61), those computers are not on UPS systems, so those computers will power cycle and should boot back up on their own. But, if you're planning to use our lab systems, because they might go up and down several times during the electrical work time period, you might not want to do your school work on those systems during that time.

If you recall, back on May 6, there was a very short power outage that affected our building and others. The testing BGE will be doing is part of their troubleshooting what happened in May.

| |
| − | ::A short outage of this type will affect our CS servers and IT services in the following way: Although our servers should physically stay running, as they are on battery-backed equipment, because our services require network connections that are controlled by JHU (and not on battery backup), all of our CS IT services will be unavailable during the expected brief outage.
| |

| |
| − | ::Once the power returns, our services should be available again, because the network should be available again.

| − | ::Also, if there is indeed an outage, the CS Grad and Undergrad Lab systems (that currently, you can only access remotely) will power off. However, when power is restored, those lab systems should automatically reboot.
| |
| − |
| |
| − | ::Other notes: WiFi and other networking in the building would be unavailable during the outage. Most likely, lights would be unavailable. My group does not maintain J-Card systems, so we do not know how the J-Card readers will perform during a power outage.

PLANNED CS IT SERVICE OUTAGES
OUTAGE: CS Linux Lab Systems Downtime/Upgrade Schedule
WHEN: Monday, August 19 through Friday, August 23
WHAT: Subsets of the CS Linux clients will be down for upgrades over the course of the week.
DETAILS: In prepping for the new semester, we will be upgrading the CS Dept's Linux clients (our lab systems and others that are remotely-accessible-only) from Fedora 38 to Fedora 40. This will require having the clients offline during the upgrades. We'll do this in stages, so there will always be some clients available at all times.
The upgrade schedule for these systems will be as follows:
- On Monday, August 19, ugrad1 through ugrad12 (in MH 122) will be upgraded.
- On Tuesday, August 20, ugrad13 through ugrad24 and masters1 through masters16 (in MH G61) will be upgraded.
- On Wednesday, August 21, ugradz and gradz (remotely-accessible only) will be upgraded.
- On Thursday, August 22, ugradx and gradx (remotely-accessible only) will be upgraded.
- On Friday. August 23, any systems that had to be skipped during the previous days will be upgraded. Our Notices page will have information about any such systems.
CS COMPUTING LAB AVAILABILITY
- MH 122 (CS Undergrad Lab/Collaboration room) is available for in-person access.
- MH G61 (CS Masters/Ugrad Labs) is available for in-person access.
