Abstract

When a hardware failure occurs within the IT infrastructure, rapid diagnosis and location of a hardware fault is required so that the failed component can be replaced as quickly as possible. The illumination of LED indicators located on the part that could fail is a common method for guiding the customer to a failed component. By using a single Indicator to identify a fault located on a component in an attached device, the customer is informed that the fault location is not in the local hardware and can look elsewhere for the fault. This saves time and effort in fault diagnosis and should reduce downtime.

Indicator to Identify Fault on Component Located in an Attached Device

Customers require that their IT systems maintain a high level of operability and availability. When a hardware failure occurs within the IT infrastructure, rapid diagnosis and location of the fault is required so that the failed component can be replaced as quickly as possible. The illumination of LED indicators located on the part that could fail is a common method for guiding the customer to a failed component.

Today's IT equipment is typically rack-mounted. Some customers have large numbers of this equipment connected together which adds complexity to locating a failed component. xSeries 360(2Q02), and subsequent similar products, had a front mounted general fault indicator. When activated, the user would inspect exterior for secondary fault, if nothing found, user would slide server open and view additional indicators for fault in attached expansion drawers. This was a drawback because of the additional steps first required to eliminate the concern of a local fault.

This submission builds upon the lightpath concept by using a single Indicator to identify a fault located on a component in an attached device, the customer is informed that the fault location is not in the local HW and can look elsewhere for the fault. This saves time and effort in fault diagnosis and should reduce downtime.
