Data Centre Transfer Switch Replacement: Service Impacts

Transfer Switch[updated Oct. 9, 2014] As previously communicated, during the upcoming Thanksgiving Weekend (October 10-13) Facilities Management will be replacing the electrical power transfer switch that feeds power to the Trafalgar campus data centre. This will require that most of the equipment in the data centre be shut down while the electrical work is being performed. Consequently, many IT services will be unavailable during the upgrade period.

Will Any Services be Available During the Service Period?

Yes. Barring any unforeseen circumstances, we expect to offer the following services:

Service Name Notes
Network Connectivity Users on campus should still be able to connect to the Internet and access any network service on campus that is unaffected by the transfer switch replacement (e.g. email)
Student/Alumni Email Students & alumni should still be able to send and receive email.
Staff Email Staff should still be able to send and receive email.
Internal/External Voice services Internal/external voice services, including voice mail, will be available.
Sheridan College website We expect that Sheridan's corporate website will be available during the service period.
SLATE Students and staff should still be able to access SLATE although some custom modules will be inaccessible, including: SLATE Self Service and Teaching w/Technology portal
Virtual Machine(VM) log-ins in Learning Commons & Labs Users accessing VMs in Sheridan's Learning Commons and labs will be able to log-in


What Services will be Impacted?

At this time, we anticipate that the services listed below will be unavailable during the service period. However, as many of our network services are interdependent, there are no guarantees that any services will be available.

​​In addition to the critical services listed below, other technology systems will also be unavailable. Information Technology is communicating with the stakeholders of each of these services directly to understand, and if possible mitigate, the impact on their operations.
