Claim of US Patent No. 10,660,239

1. A system comprising:a cooling system for cooling one or more electronic components, the cooling system comprising:
a coolant circulation loop;
a control system;
at least one primary coolant pump coupled to facilitate circulating, by the control system, coolant through the coolant circulation loop in a normal operational mode; and
a fill and drain pump sized to facilitate selective filling of the cooling system with the coolant during a fill cooling system process, and draining of the coolant from the cooling system during a drain cooling system process;
the fill and drain pump being integrated with the cooling system in parallel with the at least one primary coolant pump as a backup coolant pump to the at least one primary coolant pump, the fill and drain pump being activated by the control system to circulate the coolant through the coolant circulation loop in a backup operational mode responsive to an error in the at least one primary coolant pump; and
wherein the at least one primary coolant pump is different from the fill and drain pump.
