GB522X Motherboard Removal
Prerequisites

cover is removed.
● Part Numbers:
○ Refer to
on page 5 for a list of all spare motherboards
About this task
This procedure describes how to replace a motherboard in a CS400-AC series GreenBlade chassis. Refer to
on page 16.
● Motherboards are shipped without DIMMs, processors, or heatsinks installed.
● We recommend swapping DIMMs, processors, and heatsinks from the defective motherboard to the
replacement motherboard when both motherboards are on a stable ESD-safe work surface. This is the
preferred method versus removing or replacing processors and DIMMs from a motherboard mounted in a
GreenBlade chassis.
● After the blade is returned to the system and booted, make sure the replacement motherboard uses the same
firmware revision as the other motherboards in the system.
