The data center has scheduled a power supply replacement in one of the distribution switches to address a failure.
Date: Sunday, March 8th, 2015
Start Time: 12:00 AM CST (GMT -6)
End Time: 3:00 AM CDT (GMT -5)
Maintenance Scope: Power supply replacement in distribution switch in Chicago, IL
During the maintenance, a failing power supply will be replaced. There should be no interruption to this switch as a result of the replacement, however a simultaneous fault in the redundant power supply could cause the device to reboot. This switch is in a redundant pair and each unit has redundant connectivity to the rest of the network. In case of a problem, we expect brief inaccessibility and sub-optimal routing to occur as traffic immediately fails over to the second switch. Traffic will then return to the normal pattern once the rebooting device returns to operation.
While the work itself is expected to be completed quickly, extra time is reserved in case of problems to resolve issues without having to extend the maintenance window.
If you need assistance during the maintenance, or if you have any questions about this planned work, please contact us via our Ticket System or email firstname.lastname@example.org
