Description

An issue has been identified with the Intel

Server Chassis SC5650BRP when using the Intel

server board S5500BC.

The system may fail to power on when the “AUX” power cable (used for the Power Management Bus- PMBUS) is

plugged into the Intel

server board S5500BC. This issue ONLY occurs when using the Intel

Server Board S5500BC

and does NOT affect any other server boards that may be used with this chassis.

Root Cause

The failure analysis indicated that a capacitor (C553), which is located on the internal power distribution board of the

redundant power supply cage (Intel part number E35772-006), caused the filter circuit to fail when using the Intel

Server Board S5500BC.
