Cisco UCS B260 M4 and B460 M4 Blade Server Installation and Service Note for Servers with E7 v4 CPUs

CPUs come with two syringes of thermal grease; one with a blue cap and one with a red cap. Use

the syringe with the blue cap. This thermal grease has very specific properties. Thermal grease from

any other sources should not be used because it may lead to damage.

Left and right heat sinks are different and are not interchangeable. They must be installed in the

correct position.
