Using an earth bonding plug for grounding server rack enclosure
No!

That plug has a 1MEG series resistance to earth that allows static charge accumulation to bleed away to earth. This prevents you from destroying a component during handling with a static shock from your body to the chip. This resistor will explode if there is a fault to the chassis that causes large fault current to flow. Then the chassis could be live and floating. If you touch it, you are liable to die.

The earth connection is for safety. It must handle large fault currents to ensure that the circuit breaker protecting the circuit has time to trip.
