General troubleshooting procedures
Many problems can be resolved by starting with the following:
•
Verify no loose connections (on page 53 ) exist.
•
Search for and review any existing service notifications (on page 53 ).
•
Power cycle the chassis (" Power cycle the HPE Apollo a6000 Chassis " on page 53 ).
Loose connections
The first step to troubleshooting any issue is to verify that no loose connections exist. Verify the following:
•
Be sure all power cords are securely connected.
•
Be sure all cables are properly routed and securely connected for all external and internal
components.
•
Remove and check all data and power cables for damage. Be sure no cables have bent pins or
damaged connectors.
•
Be sure each device is properly seated. Avoid bending or flexing circuit boards when reseating
components.
•
If a device has latches, be sure they are completely closed and locked. If screws are integrated into
the latch, be sure the screws are tightened properly.
•
If problems continue to occur, remove and reinstall each device, checking the connectors and
sockets for bent pins or other damage.

power shelf. Since multiple chassis are often connected to one power shelf, this will result in power being
removed from all chassis attached to the power shelf.
