Narrative:

Las tower cleared us for takeoff on runway 25R. It was the first officer's leg from las to ZZZ. The first officer applied takeoff thrust, I assumed control of the thrust levers. At a speed of 100-110 KTS, we received the following message: on the EICAS -- right engine hydraulic pump on and the right engine hydraulic pump light on the overhead panel illuminated as well. The rejected takeoff was normal. All checklists were complied with. We cleared runway 25R at taxiway A6, and taxied normally back to our gate. No emergency equipment was necessary. Maintenance examined the right engine hydraulic pump at the gate. It was determined the pump should be replaced. Company dispatch decided to replace our aircraft with another B757 parked at an adjoining gate. We continued our flight from las-ZZZ.
