Scheduled
Time and Duration:
The maintenance window is scheduled from 10:00 PM to 4:00 AM (6 hours total) on Aug 27th. Work will begin promptly at 10:00 PM, with completion and service restoration expected by 4:00 AM.
Purpose:
We will be replacing existing Cisco 3850 switches with new Cisco 9300 switches. This upgrade is being performed to improve network performance, reliability, and capacity, as well as to ensure continued vendor support and compatibility with newer technologies.
Affected Systems:
All network connectivity (wired and wireless) will be down at the HMC B-Wing 1st floor during the maintenance window.
Expected Impact:
Complete network outage in the affected area during the replacement period. Services will be unavailable intermittently as switches are swapped and configurations are verified.
Action Steps for Users:
Before maintenance: Save your work and close any applications that rely on network access before 10:00 PM. If you are working remotely, avoid connecting to systems within the affected area during the maintenance window.
After maintenance:
Reconnect devices to the network if needed (wired or wireless). If you experience connectivity issues after 4:00 AM, please restart your device and contact the IT support team if the issue persists. Normal connectivity will resume once the new switches are fully operational and tested.
