The TS4300 is the one that can't stop. Payroll runs through it. The server room is in the back office. When it dies at 6pm on a Friday, you don't want a 'next business day' ticket sitting in a queue. This is Lenovo's Essential Service tier: five years, 24 hours a day, seven days a week, with a 4-hour response window. A technician gets to your site fast. Part number 5WS7A03773
