Bunnell Network Equipment Replacement
Problem Impact Analysis
Event Occurrence: 24 July 2024 14:45
The Bunnell West Wing switch stack is a 6 member, 48 port switch stack that provides wired network access ports to the West Wing of the Bunnell building, as well as providing connectivity to the switch stack which serves that function to the rest of the building.
On 24 July 2024, at 11:16 we received notice that one of the digital signs in Bunnell 230C had lost network connectivity. A ticket was opened, and later that day, about 14:00, investigation into that ticket began and it was determined that the switch stack member the sign was connected to was unresponsive. A replacement switch was prepared and the failed member was replaced with the new. During the replacement work it was discovered that the only active device on this particular switch was the digital sign. Work was completed, and service restored to normal operation, by 15:21.
The network should operate within acceptable service utilization thresholds and be available to customers 24/7 except during pre-defined maintenance windows.
Hardware failure. The device in question will be returned to the vendor for replacement under our support contract.
There is no countermeasure for electronics failure. Had there been more devices connected to the device, our response would have been more urgent, however all initial appearances were that the problem was isolated to the cable/wall port for the single sign, and not a switch failure.
The response to the issue at hand was in line with the severity of the problem (one digital sign offline). No further action is required.
Failed switch stack member replaced and service was restored to the one active device on that switch on 24 July 2024, 15:21.
