Standard operating practices for handling FRUs
Replace or install only one FRU at a time. Attempting to replace or install more than one hardware component at a time might cause serious system outages, processor halts, and connectivity problems.
When you handle a FRU, follow standard operating practices to minimize any potential damage to yourself or to equipment:
Complete Hewlett Packard Enterprise training courses on system support for HPE Integrity NonStop BladeSystems.
Install or upgrade only hardware components that are designated as field-replaceable units (FRUs) and for which this guide or the documents referred to by this guide includes installation procedures.
Remove all jewelry and metal accessories, such as rings, watches, and necklaces, before working with the equipment. These items can damage electrical equipment or result in personal injury.
Before working with electromechanical equipment, restrain any dangling items (such as long hair and sleeves) that could get caught in the equipment.
Inspect the FRU for any physical damage. Use a flashlight to check the connectors for bent or broken pins and look for any other obvious damage. The topic “Avoiding Connector and Backplane Damage During CRU/FRU Replacement” in the Service Procedures collection of the Support and Service library in NTL includes illustrations of damaged pins and connectors.
CAUTION:If you do not inspect the FRU and there are damaged pins, inserting the FRU can propagate damage in all the connectors it is ever joined to, which in turn damages any devices later connected to those connectors as well. If you find a bent or broken pin in the backplane, you must replace the backplane (or enclosure). You cannot straighten bent pins without damaging them. Locate all FRUs that have been installed in the slot and inspect their connectors. Follow the trails and correct any damage that has been propagated.
Examine the sockets, the connector shell, and the pin acceptance windows in the shell.
Check the outer rim of the shell for an indentation or small notch.
Check the windows for deformed ramps and obstructions.
Pay particular attention to the three right sockets on the top row (facing the connector). The most common damage is in one of these three pin locations.
When installing a FRU that is located on the front of the enclosure, work quickly to minimize the amount of time that the enclosure door is left open.
Follow ESD guidelines for working in an electrostatic discharge (ESD)-protected environment and for handling FRUs.
